Western Digital 2TB RE4 Review - Fastest 2TB Internal Hard Drive

If you're one of those hungry for speed enthusiasts and looking for the fastest 2TB internal hard drive, the Western Digital 2TB RE4 is the king in this category. The RE4 is almost the same as the WD 2TB Caviar Black, but loaded with a feature that increases its reliability that makes your data even safer. This is an enterprise drive that is built to gain extra speed besides its reliability.
What Makes The WD RE4 Fast?
The Western Digital RE4 is all about speed, Engineers at this company are devoted to create a state of the art lightning fast hard drive. This hard drive is packed with huge disk space of 2TB, to make sure that you never run out of storage for your wide collection of files. The WD RE4 runs at 7,200rpm for fast data transfer, making all your programs and games runs at vast speed.
To further add in its speed, a 64MB cache buffer is included to store most frequently used data for faster access time in a SATA 3GB/s interface. The WD RE4 is made of 4 platters in a 3.5 inch form factor. It has a total of 8 read/write heads and 500GB each platter capacity.
A dual processor design to make it twice the performance you'll need. A dual actuator technology is added for accurate head positioning. The first actuator serves as for coarse displacement using the electromagnetic actuator and the second uses a piezoelectric motion to fine tune its head positioning. In this kind of technology, you get a fast head positioning for accurately fast data access. With the Dual Actuator, a 0.4ms improvement in access time compare to other drives.
The RE4 has a drive shaft anchored at both ends not only in just one end. This feature is called the StableTrac, it further reduces the vibrations and noise while increasing its life span. This improves more durability and a silent running drive compared to other hard drives.
All Western Digital hard drives feature a "No Touch" technology. It means that, all read/write heads never touch the platters and automatically park at shuts down. Western Digital is giving a 5 year warranty to make sure of your purchase.
The WD RE4 enterprise is equipped with more additional features for making it more reliable. The multi-axis sensor protects the data written on the drive by automatically detects any shock events that may occur. The RAFF enhancement technology that monitors the drive to correct both linear and rotational vibration, thus resulting in a more reliable drive even in a high vibration environment.
To increase further its reliability, each drive is put into a burn-in-test in 24/7 operation with thermal cycling. In addition to that, each read/write head is adjusted in Dynamic Fly High in real-time for optimum reliability. Another is the Time Limited Error Recovery (TLER), this prevents the drive fallout caused by the extended drive error which is mostly common with desktop drives.
Performance
The Western Digital RE4 was tested against the 2 famous hard drives with the same capacity of 2TB. Among these are the   Seagate  Barracuda XT 2TB and WD Caviar Black 2TB, All drives are running at 7,200rpm.
For this test, two partitions are made on the same disk, a file was created on one partition and to be copied in the other partition. File transfer on the same drive on a different partition forces the drive to do two tasks at the same time that puts them under heavy loads. The first is reading the files on the source drive, second is writing on the destination drive. The time to complete these operations is measured with the speed of the drives, one is for reading and the other one is for writing.
The first test was the large file transfer with 3.4GB size. The Write/Read speed performance. WD RE4 rules the read speed while the WD Caviar Black tops in write. The  Seagate  Barracuda XT was slightly quicker in read compare with WD Caviar Black, but slower in write.
Barracuda XT dominates the write speed and the WD Caviar Black rules the read speed. However, the WD RE4 doesn't tops on both category it shows the most impressive performance and having a very small margin compare with those two competing drive.
Conclusion
The Western Digital 2TB RE4 shows the most impressive performance with all of these competing drives. The WD Caviar Black in second place with the  Seagate  Barracuda XT on third, although not much in a bigger way. These two are also worthy to be a great contender.
The additional features of the RE4 enterprise level don't go far the leads in terms of speed performance, but still that advancement pays off. The main focus for this drive is reliability that keeps your data even more secure, this is what an enterprise version is. This is ideal for servers that demands write intensive applications as well as for longer time operations.
What about the price? The price for the WD RE4 is $70 higher than the Barracuda XT and $80 compare with the Caviar Black at this time. Is the price difference worth? Yes, beside its speed performance it's got the highest reliability you can get in any hard drive which is very important in keeping your most valuable data safe. If the price would not be a problem, and your craving for an extra speed and a more secure data, go for it!

The Intel Forecast and Flash Drive Technology

My experience with Flash Drive Technology as opposed to CD Storage, has drastically changed in the usage of external and internal data storage. I have struggled with several types of data conservation and storage for many years. The upgrading of this particular hardware has decidedly corrected the dilemma. While searching for the ultimate storage media for the many types of data to which I am involved, I ran across an advertisement for flash drives. Some people identify them as "jump drives." The convenient drive(s) allows for instantaneous storage and convenience as opposed to having to burn data to a CD driven storage media device. It also allows for the saving of desktop or closet/cabinet space and fits on the end of a key chain as easily as dropping the item into a pocket of brief case. The devices have a storage capacity that exceeds many CD's, as high as 8 to 15 Gigabytes of better. Whereas, a CD may only have a capacity of only 700 Megabytes.
My review of two articles by Don Clark "Intel Forecast Signals Strong Technology" and Lee Gomes, "As Disk Drives Reach New Milestones, Flash Gains New Currency," I am inclined to agree with the majority of the information therein.
The experience of Flash Drive usage lends input from this writer's point of view. The introduction and usage of flash drives came into existence for me in 2003, while studying

computer science at the Berean Institute of Philadelphia. The experimentation and usage of these drives made for good storage media and practically wiped out our usage of floppies.
Various software applications and hardware equipment was the prime directive within the computer lab. Floppy drives were the dominant media in those days but, they just did not have the storage capacity needed for storing programs and reports. The floppy has only 1.5 megabytes of storage while the earliest flash drive media has 256 megabytes of storage. And all the while they kept getting bigger and bigger. From 256 megabytes to 512 megabytes, these drivers became the rage of our Computer Science and Business Administration, Information Technology, and Business Intelligence Communities.
Mr. Gomes was right on target with his report. These convenient and devices have continually and continue to evolve into major mass media storage. Mr. Gomes speaks of 1 gigabyte sized flash drive devices and larger in the coming years. Will the flash drive storage capacity ever reaches a limit on its storage size? I believe that I will wait and see.
The utilization of CD's for software storage is greatly appreciated by computer users, music lovers, movie lovers, and the mass technology population. It's capacity to store large amounts of data are a necessary media tool for computer and mainframe users.
Albeit, tape drives all the storage media of choice for many technicians. The large capacity flash drives 16 and 32 Gig's, of which Mr. Gomes speaks, will be a much welcomed commodity. I wonder if the average PC user is in need of 100 Gig's of storage? I'll wait for that time to come as well. Semiconductors that are produced by the Intel Corporation and comparable companies do indeed support evidence that technology demand is broad based and accelerated, as reported by Mr. Clark. The Intel remark also supports the encouraging signs regarding the health of the computer market, including its related products.
Although this reporter's interest in primary mainframes and its revenue are not a focal point, the market health of PC's is. Hewlett-Packard Co.'s report its third quarter earnings rose 33% in its fiscal third-quarter, according to Don Clark also points out Dell Inc.'s subsequent jump in its profit earnings, as did   Seagate  Technology.  Seagate  Technology manufactures disk drives. Its benchmarking rival, Western Digital Corp., reported its revenue progression also, said Mr. Clark.
Don Clark stated Bill Watkins' views of an "explosive growth in the industry over the next five years." Apple Inc. reached its goal of i-phone sales, as reported by Mr. Clark. At Jeffries an Co., Mr. Lau, an analyst at the co., said demand is surging from the companies that purchase PCs for employees as reported Mr. Clark. He also said that growth is strongest in notebook PCs. Mr. Clark quoted Paul Bell of Dell Inc. as stating, "notebooks continue to explode as a category." The competition between Intel and AMD is forcing both companies to step up the pace of product introductions and price reductions. This action boosts the appeal of both consumer and business companies, reported Don Clark.
This reporter goes on to state the long awaited version of the Opterion Chip line for PC and Network servers. The chip is reported to have the equivalent of four electronic brains on a single silicon piece. Don Clark continued to report Intel shares fell on the stock exchange while AMD's shares rose.
The report(s) were very informative and enlightening. It is recommended reading for individuals with interests in computer technology.

The Truth About Online Backup Services

Now, I will admit part of me is thinking, "What in the heck am I doing trusting an online backup company far away to store my data?"
None of us is conditioned to trust people we don't know or let them see our data.
We have become a paranoid nation...No one is supposed to see my stuff!
With HIPAA laws to protect us from other people finding out our health records -- like anyone really cares about my health records -- and screen shields to keep the guy at the next table at the coffee shop from seeing our work, we are afraid of data-peeping Toms.
My feeling was, it is MY data and I just don't want someone else's prying eyes looking over it seeing all my work and my play.
With all that said, what is the truth about online backup services and can they give you peace of mind?
Can they really simplify our lives or they just another opportunity for a gullible public to get screwed and look like an idiot?
Make up your own mind, but I confronted my fears about sending my data way off to be stored and started using internet backup some time ago...
Here is the logic I used in deciding to trust the online service:
1. Just thinking about backing up is worthless...it is done daily -- I wasn't doing backup daily (I am embarrassed to admit, not even weekly.)
2. The backup copy needs to be stored remotely or it is worthless -- My external drive was kept at my house.
3. The external hard drive I was using started to have maintenance issues -- I was constantly dealing with   Seagate  customer support to figure out if my  data  was actually being

stored on the drive.
4. Admitting to myself the solution had to be automatic or it wouldn't work.
What is the truth about online backup services? The real story is, the model isn't perfect but it works. It is cheap -- about $5 a month and you can set everything up one time an forget about it.
Bottom line -- If you choose one of the larger services, like Mozy or Elephant Drive, you can sleep at night knowing your data is protected.

External Hard Drive - Keeps Your Data Protected

A storage device that functions similar to an internal hard drive with the only difference that it can be connected via a USB port and is placed outside the CPU is called an external hard drive. The device is very popular for the simple reason that it makes your data portable and secure from threats. With heavy internet access the hard drive is exposed to threats like virus, spyware and Trojan horses. It becomes important to safeguard your data from such threats and this is possible only with a highly secure external drive. Not just online threats even many people using the same system can put your sensitive documents at risk. This is where password encryption comes handy. Moreover with multimedia information on the rise need to store this digital information safely become a priority, which can be done using external drives.
Sitting outside the computer enclosure the external hard drive acts as a storage device that lets users to store any type of data either for sharing or for backup. Many use external drive for backup purpose, incase the internal hard drive fails. The external drive is connected to the computer with the help of a high speed interface cable. The external device can be connected to the computer using USB port. These days you can find high speed USB 3.0 interface that allows data transfer twice the speed of a 7200 SATA drive and ten times that of USB 2.0 interface. The drive is small and compact and can fit into your pant pocket or your purse comfortably. Some drives come with power grip that protects the drive from rough handling.
External hard drive comes in a number of interfaces like USB and FireWire. Depending on the port availability a drive can be chosen from the market. Some drives also come with both the interfaces making it versatile. Large backup of movies, music, graphic and games can be taken comfortably on the external drive as it comes in terabyte capacity. The device also comes with 256 bit hardware encryption that when enabled allows access to only authorized users. This is a welcome feature that protects the external drive from the prying eyes of trespassers. The external drive is easy to operate and does not require any special software for backup, though most of the manufacturers offer free backup software that can be downloaded from their website. Some even offer online backup up to a few gigabytes free space.
The easy access feature of the external hard drive has made it highly popular. You can carry sensitive data with you wherever you go. Once the computer recognizes the drive, the drive is assigned a letter and you can start transferring files to and fro onto the external drive. It works just like an internal hard drive. Huge files can be transferred back and forth without any hassle. The device can take as many rewrites as possible and can stay with you for long. You would realize that backup on the external drive is very useful especially when you experience internal disk failure.

External Hard Drives - Best Storage Solution

External hard drive is one type of the hard disk drives that is made for the external storage use. Actually, it is connected outside the computer system (desktop & laptop) by USB port or FireWire. It has the main functions like data security, mobility, backup system, and choice to remove the device and take your data. There are 2 kinds of the external hard drives, which are portable hard drive and desktop. In spite of different kinds of external hard drive, however it doesn't work differently. It very different in the terms of convenience and portable hard drive is much smaller & lighter than the desktop hard drive, and it is made for simple carrying in the pocket, briefcase and purse where no one will steal the information.

My Opinion on Portable External Hard Drives

Hi all my name is Kerron, and basically I just wanted to share my opinion on why I think portable external hard drives are a very valuable device to have around. We all have massive amounts of data stored on our internal hard drives whether it's PC or Mac, and if your like me, the thought of losing all my music collections, videos, photos and important software can be a terrifying experience.
Well I was fortunate (not really) to have one of those so called "Blue Screen Of Death" moments where apparently some sort of system file got corrupted, or so Windows said and for nothing it would boot into my profile. Needless to say, I have never done any sort of backing up in my life ( when I first heard the term "back up" I thought it to be a very difficult and tedious process that only people with technical knowledge could perform) which is why i never really bothered with the task.
Luckily for me I was able to take my PC to the local computer repair shop, and after a quick diagnostic ( like literally quick, the guy powered it on took one look at the error and said he's gonna have to reformat my hard drive), he then asked if I had previously backed up my data at any point prior to the crash. I kept my cool, and with a calm, relaxed voiced I replied NO. After a very cheeky smile, he told me not to worry he would be able to retrieve my data and "back it up" to a portable external hard drive so he can restore it later. That term external hard drive had sparked my interest.
I was a bit curious to find out how it worked and was getting ready for some long tech jargon (that i would probably have to go look up after agreeing with what he said). Instead he brought out this little back box no bigger than the palm of my hand which isn't very big, and explained all that all he needed to do was plug it into the USB port and after the windows recognises it automatically, it's as easy as copy and pasting what ever type of data I like across to the external drive. Now the process to retrieve my data was a more complicated one (which I didn't quite fully understand) so I won't get into that. But I was sold on the idea of this little black box that is capable of holding my most valuable data, and the process of " back up" was as simple as copy and paste.
After getting my PC back up an working (big smile), I decided to invest in one of those portable external hard drive (there were also larger sized ones that you can place on your desk, but I like the idea of portable data) for keeping my data safe. I was actually surprised that it was not as expensive as I thought. I paid under $100 USD for my Seagate 250gb portable external hard drive, that was actually more storage space than my internal hard drive (kind of old PC). All I have to do is plug in the external drive into the USB port and it's as simple as drag and drop my data. Now I rest comfortably knowing my most precious data is safe from unexpected system crashed, and the best of all what i really like about these portable external hard drives are the fact that you can take them with you anywhere and they only weight a few ounces, I've seen cell phones weigh more than them.
I highly recommend investing in a portable external hard drive if you have never backed up your data or need more storage space for backing up data, and also if you travel a lot and need access to your personal data on the go. Feel free to visit my blog where I discuss certain factors to look at when purchasing a portable external hard drive.

USB 3.0 PCI Adapter for Super Speed Data Transfer Rates

Once my manager asked me to transfer huge data files (up to 300GB) from the server to the external USB 2.0 hard drive, it took me hours to complete the task successfully. The reason why the data must be transferred to external disk was because the data must be copied to the mirror server in Sydney. It was in remote site where communication must be done via satellite. WAN link between remote sites to central office use satellite link with only 512 Kbps bandwidth.
Normally we use the autoloader tape backup as the central backup system for all the data servers. Autoloader tape backup solution is very advantageous for multi-server environment which reduces the overhead cost and time spent by the administrator to maintain the backup system. I didn't copy the data on the backup tape, which must be easier and faster, because the backup cartridge used in remote site was not compatible with the mirror server in the head office. So, the solution was to transfer the data to the USB 2.0 external hard disk.
The maximum data transfer rate for USB 2.0 based adapter is around 480 Mbps. Actually this is a fast enough transfer rate for home usage. But for business environments where huge data backup / data transfer tasks frequently use USB external storage for some cases, the transfer rates of up to 480 Mbps (using USB 2.0 based device) is not fast enough to support your data copy tasks. Today, you can use the Super Speed USB 3.0 for super speed data transfer rates of up to 5Gbps using USB 3.0 card adapters. With USB 3.0 card adapter, you can transfer your business data to the external USB 3.0 storage (such as Iomega eGo 2 TB USB 3.0 external hard drive) 10 times much faster than the speeds of USB 2.0 devices can transfer.
This type of USB 3.0 PCI express card adapter will only work on the computers / servers that support PCI Express slots. Peripheral Component Interconnect Express (PCI Express or PCI-E) is PCI which uses a much faster physical-layer communications protocol than traditional PCI bus architecture. PCI-E uses dedicated, unidirectional, point-to-point connections lanes to communicate with PCI Express devices.
The following are two types of USB 3.0 PCI-express card adapters you can use for your computers with PCI-express enabled.
TRENDnet 2-Port USB 3.0 PCI Express Adapter TU3-H2PIE
TU3-H2PIE is a USB 3.0 Card to add two super speed USB 3.0 ports to your desktop computers or servers with PCI Express enabled. It can support the super speed transfer rates of up to 5Gbps which is 10 times faster than traditional USB 2.0. The adapter is backward compatible with traditional USB 2.0 devices. It supports Windows 7 (32/64-bit), Windows Vista (32/64-bit), and Windows XP (32/64-bit).
Belkin SuperSpeed USB 3.0 PCI Express Card
Like Trendnet TU3-H2PIE, Belkin USB 3.0 Card adds two USB 3.0 ports to your desktop computers for super speed data rate transfers up to 5Gbps. It is also backward compatible with USB 2.0 devices. Belkin USB 3.0 can support computers with Windows XP; Windows Vista, and Windows 7 platforms.
USB 3.0 PCI adapter is a high speed data transfer rate solution for your business computers. But you can use the adapter only if your computers support the PCI Express slot. To obtain the maximum data transfer rates of up to 5Gbps, you need to connect the adapter to the same USB 3.0 devices such as Iomega eGo 2 TB USB 3.0 disk drives.
