I purchased a Western Digital WD7500AYYS 750GB SATA II drive. I installed,
partitioned and formatted. Everything seemed fine, but I noticed file
transfers seemed incredible long.
Background:
Gigabyte GA-K8N Ultra 9 motherboard with onboard SATA consisting of:
nVidia SATA II RAID (4 sockets)
Sil 3114 SATA RAID (4 sockets)
I added 2 PCI-E 1 SATA RAID cards:
Sil 3134 SATA RAID (2 sockets)
JMMicron JMB36X (2 sockets)
Originally had 7 hard drives:
5 Seagate 320 GB SATA II
2 WD Raptor 36 GB SATA I
I always had trouble getting the Sil 3114 SATA RAID setup to work with the 2
WD Raptors as a RAID0 boot array. I settled on running the Raptors on the
nVidia SATA RAID along with 2 Seagates as JBOD. The other Seagates inhabited
the two add on cards. The Sil 3114 could be used for data disks.
I replaced one of the Seagates on the nVidia controller with the new WD 750
GB and started transfering files. They seemed to take forever. So I did some
timed tests of a 350 MB file transfer. Between any two drives NOT counting
the new WD, 11-18 seconds. Transfers to the new WD 750 took about 3.5
MINUTES. Transfers from the WD 750 seemed normal. I tried the WD drive on
every controller with similar results. All the other drives seem to operate
normally.
Desperate, I tried the WD 750 on another computer. It seemed to operate
normally. Transfer times to and from the WD 750 drive for the 350 MB file
were in the 10-15 second range.
I have updated to the lastest drivers for each controller.
Anyone seen similar behavior or have an idea of what is going on? Since the
drive works on another system, it is hard to fault the drive. But all the
Seagates work just fine on the original gigabyte motherboard, so I am not
ready to fault the motherboard. Any ideas?
Thanks for your input.
