A friend of my also has a raid5 with 4x1.5TB with his onboard raidcontroller. But his writespeeds suck pretty hard. His read is very nice, about 500MB/s, but his write is like 50MB/s. Now I was wondering what your writespeed is of the raidvolumes since you have the non-onboard raidcontroller in use? hi,

After reading some documentation, it looks like I might have to update the card to take advantage of it. Not a problem; I'll just have to do it tomorrow afternoon when I can reboot the box and find the hptflash utility. Ah, wait, you probably mean the BIOS-based utility and not the Windows admin UI?

If you're still following this, can you point me to exactly where in the HighPoint utility one would go to change the sector size? The documentation is a bit sparse on this point. Thanks Neil!

By increasing the sector size, you effectively get a larger partition with the same number of bits. I was doing this with an extra drive that is separate from the OS drive. We're using the newest 16-port HW RAID card (they just released it).
