x2 SPINPOINT F3 500Gb RAID0 Seek Time Too High??

[ChaosInMind]

First raid array since 40gb IDE drives were main stram and AMD was first to the 1GHZ mark...

First pic is before I enabled write-back cache, 2nd is with it enabled

I've seen many screenies of short stroked Spingpoint 500gb F3's and the seek time is 7-8ms, Not 10ms. I did a 200ish GB short-stroke like them as well...


Any ideas? Stripe is 128kb like everyone elses.

Can a MOD please move this to the HDD thread? I must have been drunk when I posted this.

Were those low seek times you mentioned seeing for a pair in RAID0 or for 3 (or more) in RAID0?

I ask because I too saw those types of numbers when running a pair of WD Black 1TB drives. Once I put my third one into the mix, the seek time dropped, a LOT.

It's just two 500gb drives. I plan to buy a third or fourth a few months down the road.

I believe the Spinpoints are faster drives than my WDs but I can say that I went from ~12ms access times to the low 9ms range when I went to 3 drives so that's nearly a 25% improvement from adding a third drive...you should see even better numbers once you add a third to the mix

I'll keep that in mind.. Yeah the Spinpoint F3's are "faster" when it comes to sequenchial read/write but I think the access times are a bit slower.

Do you have your drives short stroked though? You could probably get less than 9ms if you short stroke a 300gb OS partition with the 1TB drives. Thats 50GB per platter (50GB x 2)x(3) then RAID1/5 the remaining disk for backup/storage.
