Hi there folks, I just set up a RAID 1 setup on a machine at my office for a little extra data security. Card plugged in fine, software worked, and the drives were even recognized without issue. Once I initiated the data migration, however, I noticed it moved *extremely* slowy. As in 20% migration/day.
I presume this is excessively slow, but as I have no experience with RAID previously I can't say for sure. Should it really take 5 days to migrate a 320 gig drive to a RAID 1 setup? Advice, clues, and/or hints are welcome (even if it's just to say "That's way too long!").
Go into "Device Manger" on your Computer.
Go to IDE ATA/ATAPI controllers and selct your various "channels".
These should tell you what the "Current Transfer Mode" is on those devices. It should be something like "Ultra DMA Mode 5" or the likes.
Anything with DMA is "OK". If you see "PIO", then you are going to have real bad performance. MB Driver updates are often a resolution for going from PIO to DMA.
Just got a look, and the two primary IDE controller channels are both DMA, secondary channel is not in use, but I presume that's because the RAID card sees the two drives as one. Any chance I could grab another suggestion?
I have 3 of those cards but the 5 port versions, and yeah they do take forever, even at the fastest migration speeds it still does it in slow "bursts" so the data can still be accessed at a decent speed. You'll just have to sit it out.
