Dell Model UCS-51 questions / issues

post #1 of 8
Thread Starter 
I just acquired a Dell Model UCS-51 board with a 15k RPM Fujitsu max 78gb harddrive, I have it plugged into my PCI-E 16x, I'm running Windows 7 Ultimate 64-bit.


I haven't seen any improvement in speed at all, The guy I got it from said it was "Not as fast as a SSD, But alot faster than a basic SATA drive)

I can't say I've seen a difference. Am I doing something wrong? Upgrade firmware? Wrong drivers?

I need help... Because if this isn't gonna help at all, It's just gonna get put in the Parts bin that's collecting dust.

run an HDTune Pro bench, both the sequential and random tests.

and do the same on your SATA drive, and post all the results.

Will do. Gotta reformat my dang SATA Drive though.

If there isn't a difference, What should I do with the Dell USC-51 board and the 15k SAS SCSI drive?

Would it be possible to convert the drive (Via cable) to be used with regular SATA?

don't need to reformat - HDTune ignores any data on the disk anyway.

Sell them if you don't want to keep them. I'd find it hard to believe you won't notice a difference though - it's not so much when you move to the faster drive that you notice the speed increase. Instead you get the realisation when you move back to a slower drive afterwards, and it feels like you dropped your rig in treacle.

Alright. I'll get that tomorrow. For now it's sleep time

PS: Would there be a bottle neck issue because it's in a PCI-E 16x slot? I heard these were for PCIE x8 of some form.

Nope - in fact that card would be perfectly happy in an x4, x8 or an x16 slot and you wouldn't be able to tell the difference. With a single drive even an x1 slot would perform the same.

Here's the results for the SCSI drive:

And theres the results for the SATA drive.

Something doesn't seem right here....

Looks spot on to me. Lower max speeds (lower areal density, smaller platters), but much better access times.

All in all, it demonstrates that 15k drives make poor storage drives (slow max transfers, high cost/GB, low density), but great OS drives (excellent random performance, bettered only by SSDs - but then SSDs do destroy them completely).
