- NCQ + 16MB = nice improvement over the 8MB models.. one of these single rapy is ~20MB/s faster than my other 74 8MB.
- Got 4 of these rapies in RAID0 on the Areca 1210 i got from newegg aswell for ~320MB/s avg. read in HD Tach benchmark.. TCQ/NCQ + read/write cache enabled.
- Very quite, even 4 of them.
- Temp.wise, very cool running.
- Did i mention they're fast.. custom winxp install in 4 minutes.
None so far..
If you want the highest performing sata hard drive, this is it!
The disks are very fast and much less expensive than SCSI + controller card.
I have bought 8 74GB Raptors over the last 2 years. Two of them, in a Raid 0, have failed. WD replaced both through there RMA process. The first took a week to replace but the second took almost a month. Since I couldn't wait that long, I bought another.
Currently I have two Raptors in a Raid 0, two in a Raid 1, and a single on another computer. If you are planning to use Raptors in a Raid 1, I suggest you check WD documentation on time-limited recovery. It may be that feature causes the causes recoverable disks to be lost. I've enjoyed the disks' speed but am not used to having disks die on me.
