i have found shocking sandra scores with promise raid and seagate iv drives 21mbs slower than with a single drive 24mbs. maxtors score 32mbs in raid and if I get rid of raid card make system partition on each drive of say 4Gb, dynamic the discs and then stripe remaining, instal op into one of the 4Gb partitions format large partition ntfs 64K I get 37mbs. why is seagate so bad?
I think its your configuration. I used to run raid with 2X40 GB seagate IDE with an onboard promise controller (I was using the MSI K7T board). it performed well.
nah prob with seagate iv drives older drives fine
What was your RAID configuration - I’m getting 37MB/s Sync with just one Seagate Cheetah u 160 SCSI.
My other station has RAID Level 0 and 2x72 GB SCSI Cheetahs - I’m getting 51MB/s Sync transfer
your not doing something crazy like striping together a 10k RPM drive with a 7k RPM drive? or a 7K with a 5400 are you?
sounds like mismatched drives which can cause RAID speeds to plummet through the floor. We regularly sell seagate cheetahs because their fast reliable drives.
sorry IDE 7200 RPM SEAGATE IV Drives
matched 40GB IDE 7200RPM seagate IV
were they on the same channel?
or seperate both as masters? and were they both alone ?
IDE sucks for much this reason
on board raid promise msi kt266a both as masters by the way thanks for the feed back
thats somewhat unusual in any case. you should see at least a 50% increase in write performance and anywhere from 75-100% improvement over a single drives read performance. Possible one of the drives it faulty?
Ive heard seagate acknowledges the prob but no fix in prgress be warned dont use seagate IV ide in raid configs
I have just installed and benched dual p3 1Ghz CUV4X-D board with 3ware 3w-6400 raid controller with 6.9 update on win2k 4x80Gb seagate drives in stripe RAID-0 as a video drive 1 320Gb drive ntfs, sandra scored 21mbs, whots up?
I couldn’t get any info off their website? I assume thats a 4 channel card? if it is hrmm might wanna fiddle with drivers. if its a 2 channel card then I can see performance dropping because even though 1 channel supports 2 drives; adding the 2nd drive will slow a channel down.
