Promise Fastrak 100 TX2 RAID 0 Array w/ 2 Westernd Digital 120 GB SE (ntfs) in Win XP
Posted on 2003-03-21
Let me teel you my story...
I bought last year a Promise Fasttrak 100 TX2 Raid controller, that I've been using with 2 IBM Deskstar (40Gb) in RAID 0.
Performance was ok! In Sisoft Sandra I had results of near 50Mb/s with 64k Stripe and FAT32 partition.
But, as you know, IBM hard drive aren't reliable at all, so I recently bought 2 Western Digital 120 Gb Special Edition hard disks (Superb!) with 8Mb cache.
I installed them and made a 64k array, and formatted the 240 Gb partition with NTFS file system with 4k clusters!
When I ran the first Sisoft Sandra 2003 test I was shocked: only near 30Mb/s tests, and noticed the sequential read/write tests were strangely low....
If I format the array with FAT32 the tests results are, again of 50Mb/s.
What is very strange is that several people with NTFS partitions in RAID0, 64 k stripes get results of 47/48 Mb/s.
I made alltests possible but I just can't find the problem!
One last detail, in HD Tach, the results in NTFS are exactly the same that in FAT32: almost 49Mb/s.
What is more reliable?? Sandra or HD Tach?
Is it possible that Sandra has any kind of issues with any software or driver installed in my system???
I woul appreciate some hel from you.
