Re: RAID array software -- what are you using?

Hi folks:

Thought I'd update you on my progress.

Decided to try out the WD drives mentioned above. They seem good/fast/quiet -- the only drag is that WD's accounting for GBs leave something to be desired...their 400GB drives show up as 372.5 GB on the desktop. (don't knkow if Seagates are the same, but...) At any rate, I've tried a few 2-disk tests with the Apple Disk Utility and seem to average about 125 MB/s Read/Write on the Kona 2 tests (sweep Video Frame Sizes, 1 GB File Size). I've tested the RAID set-up with both 32K, 64K and 128K blocks -- seem to result in about the same performance on this test. My only question is: in the real world, is there any advantage/disadvantage to any of these block sizes? Just want to be thorough before I commit data to the array. BTW, I tried the 256K block size, and the read speed drops to the basement at about 55MB/s. Funny that...

Anyway, loving the Seritek enclosures/card. They're quite, cool and well-designed. I tried some hot-unplugging and replugged the RAIDed drives into a second enclosure, and the Mac reminded me what I was doing, and then they happily re-mounted as a RAID with all data in tact.

Hope this info is of use to fellow COW members.

Best, JIM.
