Why pay for someone else to build one (one size fits does not fit all) when building your own is not too difficult and you can build with quality parts tailored to your own specific needs. Case in point, the WD 640GB HDD. Large hard drive prices are economical right now. Generally speaking, the larger the drive, the less the cost per gigabyte (GB). At Amazon's prices the WD 640GB drive was about $10 bucks more than the WD Caviar 16 320 GB drive with the same cache. Western Digital has recently color coded their drives: Black (high performance), Blue (mainstream) and Green (no brainer: ecologically friendly-for a hard drive). Where does marketing get these ideas? The Caviar 16 640GB falls into the Blue category. It is amazingly fast and quiet, thanks to its 16 MB cache and 3 Gb/s transfer rate. The technology is interesting in that WD utilized two 320GB platters which gives this drive an edge as compared to say 750 GB drives with similar cache...Read more 33 of 42 people found the following review helpful: By Amazon Verified Purchase(What's this?) This review is from: Western Digital Caviar Blue 640 GB Bulk/OEM Hard Drive 3.5 Inch, 16 MB Cache, 7200 RPM SATA II WD6400AAKS (Personal Computers) The hard drive worked great I had to go online to get the product manuals and purchase the cables since it is a SATA II drive and my computer supports SATA I it took me several hours to make it work but once I figured out how to slow down the drive with the jumper which was not supplied it was a plug and play process. Make sure you know your system specifications before you order and get the needed cables and jumper & Screws all at once. 5 of 5 people found the following review helpful: By Amazon Verified Purchase(What's this?) This review is from: Western Digital Caviar Blue 640 GB Bulk/OEM Hard Drive 3.5 Inch, 16 MB Cache, 7200 RPM SATA II WD6400AAKS (Personal Computers) The drive is pretty fast and allows for allot of storage room. Amazon needs to learn how to pack a hard drive for shipment! The hard drive arrived in a box with a static bag around it and no protective padding at all!!! My drive is warrented until 2012 from WD and it is already making noise upon spin up. So it looks like I am going to have to ship it back to WD for replacement. I would not purchase this item from Amazon again not because of the drive; but because of the horrible packaging the drive was shipped in. |
