Ahh but Raid 5 can only deal with a single dead disk

Oh well raid 6 or 10 then. Do you think he'll have room for all the disks?:eek:

I'm sure I could talk to somebody about selling him some enclosures and a rack or two

Which WD-AAKS is it you have?

Is it one of the energy efficient models? If so that might explain a few things if you have a read into it.

Its the 640gig dual-platter one.. it is possible that it might using AAM, except none of the software ive used previously to change the settings on drives worked on it.

EDIT: have re-visited this... by using a tool called WINAAM i can change the values, (but only after changing the sata controller back to ATA instead of AHCI.. the drive was in "loud" mode, but it still gets absolutely obliterated by the raptor for random seeks.

Edit2: i see there are several threads on the internets about these drives and there being two versions:

65A7B0 default AAM 128, access time ~16ms

00A7B0 default AAM 254, access time ~12ms

(i have the 65A7B0 ver)

Ahh right yes random seek is a place where you will see an advantage from the 10k drives as each block is in a difference place to the density and cache have little effect.

To be fair though, IMHO, if a home user is doing a large amount of random seeks other than through a benchmark then they really need to defrag their file system.

Or has windows as an O/S
