hard drives & raid - benchmark and compare!

Recommended Posts

My home system is slow compared to what I'm used to working with.

Well, finally got my SATA2 2 disk raid array set up last night. Take a tip from me, dont drink and install os and raid array!

Everything is awesome, love these drives, but I think somethings wrong with them.......

I thought it might be a fluke but I tested them about 20 times, but this is what I get every single time

 

:nod::shake::nod:

====================================================

EDIT: This is with 32kx4k stripe/cluster size. I changed the cluster size to 8k and noticed no difference whatsoever in speed, burst or transfer rate. The only difference I saw was a 1% drop in CPU utilization with the 8k cluster. I'm still not sure why the burst speed is so high. The only thing I can think of is that in the Hitachi feature tool I set the idle speed higher and left the Acoustic Control disabled.

====================================================

I think my lights in my house even turn on faster now!!!

For the price of 2 Hitachis, these r unbeatable. Way faster than the SATA drives I had before!

This is the ATTO screen of the 8k cluster size. This has improved alot with 8k. The 4k cluster seemed to drop off quite a bit around 16to32.

I think I'll stick with the 32/8k

I've got a set of WD2500KS. Have just been trying to work out what the best setup is with them. Benchmark of the default settings:

So I finally got round to setting up a Raid array of my own. Never done much work on Raid before, First run after setting up a clean XP (forgot to defrag first though) So I guess these are pretty raw results for now.

 

Everything is set default at the moment, 64K Stripe + NTFS Default
