WD Caviar Blue – Performance and reliability for everyday computing
To make drive selection simple, we've gathered all our popular WD Caviar SE16, WD Caviar SE, and WD Caviar drives under one umbrella we call WD Caviar Blue. Built to Western Digital's awarding winning quality standards, these drives are available in a full range of performance features.
PATA - Enhanced integrated drive electronics (PATA), also called Parallel ATA (PATA), hard drives have been the standard in the computer industry for more than 10 years.
SATA - Serial ATA (SATA) hard drives are quickly becoming the new standard. Motherboard manufacturers now include SATA inputs on their boards. Because of their considerably narrower cables, SATA hard drives provide increased airflow and less clutter and in the computer system compared to PATA drives.
The performance difference - PATA drives support data transfer rates up to 100MB/sec, and all WD Caviar Blue SATA drive support 3 Gb/s transfer rates.
Cache - WD Caviar Blue is available in 2 MB, 8 MB, and 16 MB cache sizes. Bigger cache memory yields faster performance.
Capacity- We offer drives ranging from 40 GB to 750 GB. Pick the biggest capacity your budget will allow. You can never have too much storage space.
Reliability - We understand the importance of your data, and we are committed to protecting that data with exceptionally reliable products, advanced data protection technology and superior customer support.
Cool - Keeping the drive cool enhances reliability. WD continues to develop new and innovative ways to keep drives cool while they are operating.
Quiet - The technology that Tom's Hardware Guide called "very fast and nearly silent" is used throughout this family of drives. Our WhisperDrive technology minimizes noise to levels near the threshold of human hearing. To cut seek noise, SoftSeek technology streamlines read/write seeking algorithms, resulting in more efficient operation.
NoTouch™ ramp load technology - The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit. (Available on 120 GB capacities and above)
IntelliSeek™ - Calculates optimum seek speeds to lower power consumption, noise and vibration. (Available on 120 GB capacities and above)
Compatible - We perform tests on hundreds of systems and a multitude of platforms in our FIT Lab and Mobile Compatibility Lab to give our customers confidence that our drives will work in their systems.

Top Customer Reviews
It has been months.
Not a hiccup.
It is very fast. Noticeably faster than the stock 160.
And it is very quiet.
It has increased my system speed and gives lots of room for expansion.
I am impressed.
Update January 2009. This drive is still going strong and works great every day.
Update January 2010. This fine piece of equipment has yet to have a problem.
If you want to replace a failed drive and don't want the clutter that usually comes with a drive, this is for you.
If you want to add an additional drive to an existing system, you'll need to get the cabling and mounting hardware elsewhere.
My only complaint: the drive is warranted for 3 years not 5.
Amazon had the lowest price I found, and shipped the drive quickly. Turn around time from placing the order to delivery at my door step was four days. Stable, reliable and excellent price to performance ratio, this drive is a great choice for everyday computing needs.
Newegg (as of 8 months ago from this posting) still has problems with DOA units. I think Newegg may stack these and stress surface mount components, etc. No such problems with the amazon.com drives so we buy 100% of our drives from Amazon.
- Bulletproof (the AAKS) We have 20+ (now 30+) of these in Dell T3400 Precision workstations and put 3 in each machine.
NOTE: We have not had even ONE problem in 2+ years of NORMAL use - see 01/05/2010 update - (oldest 12/30 drive units are 2+ years old, others are 1+ years).
- None that I know of so far.
Did a lot of research on the platters they use on these drives and the technology. The AAKS seems to be the sweet spot in the line. AACS and AAJS were a bit different but not much. The WD5000CSRTL model seemed to have the most problems.
The environment these drives run are lab servers that are "ON" 24/7 so we don't get the same ON/OFF cycles that a home system would have.
Checking the hard drive
Run the "WD diagnostics" that come with the disk or you can download the utility from the Western Digital site to find bad sectors just in case you get a bad one (we never have).
This utility will run on *ANY* disk (not just WD). It may take a few hours for a "full scan" but it's time well spent.
01/05/2010 Update: Finally lost one of these 500GB drives due to a move to a new building. The drive was near 2+ years old. The head didn't crash and the drive spun up but Windows XP wouldn't recognize it so it needs some specialized software kung-fu to re-mount the drive.Read more ›
