It’s the time of year for many publications to list their Holiday gift guides and lists. TechSpot has a variety of interesting items but I guess I’m most attracted to the geekiest, the Western Digital Caviar RE2 400GB Hard Drive (Serial ATA-150, 7200 RPM, 16MB – SKU: WD4000YR). But there’s a trick – get two and put them in a RAID 0 configuration:
For that special geek in your life, give the gift of tremendous storage capacity. Sure, you can slap just about any drives together, but the WD 400GB RE2 (WD4000YR) drives really shine in RAID configuration. Not only will you be pairing two of the fastest 7200 RPM / 16MB cache drives available, but you’ll be giving the recipient 800GB of storage in RAID 0… Every computer nerd’s dream!
Sounds good to me! However, note that you don’t want just one:
Just shy away from the WD4000YR as a single drive, since it does not provide the same error protection redundancy found in your traditional, “solo” SATA drives.
StorageReview.com, who has a detailed technical review, elaborates:
In the end, the Caviar RE2 WD4000YR sweeps our high-level performance tests across the board. Equipped with a solid NCQ implementation, the drive’s multi-user scores never falter and top the competition whether in a light, a medium, or a heavy load scenario. Combined with the drive’s presumed (given the 5-year warranty, 1.2m MTBF, and Raptor-leveraged heritage) reliability, the WD4000YR emerges as today’s preeminent 7200 RPM offering for server use.
Despite this stellar performance, however, WD cautions against using the RE2 in a desktop system. The drive’s TLER feature expects to be paired with a RAID controller. In the event of an unlikely but possible error situation, the RE2 may not make every attempt to recover when operating on a regular controller as a standard SATA drive would.
I guess it depends on the size of your desktop system!
