Hello,
I bought 2 WD raptors and the Highpoint RocketRAID 1520. Standard raid 0 configuration, 64Kb block size.
Both on Linux and Windows I didn't feel the expected speedup, so I tried the Bonnie benchmark in Linux (with really disappointing results) and HDTach 2.61 on Windows. The latter gave this result: Read speed max 50Mb/s, min 19 Mb/s (!!!), avg 43Mb/s, random access time 8.7ms, burst speed 62.1Mb/s.
Sandra gave me a low 30Mb/sec.
Now, beside access time, this is barely better than my old hard disk (IBM DTLA703070!), and seems way low even for a single raptor.
What the hell is going on?
My system is a dual Athlon 1800+ in a A7M266-D with 1Gb of ECC PC2100 RAM.
A few more info/questions:
1) I tried to plug the RAID adapter in the 64bit/66Mhz slot, but due to lack of 3.3V support (sucks!) on the RAID adapter, it won't POST... but in a 32bit/33Mhz slot there should be enought bandwith do much more than this, shouldn't it?
2) My mainboard BIOS is updated to the latest version, while trying to flash a new BIOS in the RocketRAID 1520 gave me a "No Loadable EPROM found". I have a PCI card, not an integrated adapter, what is going on? I'm writing HPT customer support...
3) Both Windows and Linux have assigned IRQ 18 to the RAID controller... is this normal? Before booting the motherboard says the assigned IRQ is 9 or 10.
Thank you for any info/help you can give me, and if possible (since other people have 1520 + 2xraptor, I've read it in previous posts) I'd like to have an estimate of the expected performance (I guess it should be more than twice my current values).
Best regards,
Andrea.
