Hi, Thanks for your input. Unfortunately, all 3 drives are identical Seagate 7200.11 drives which I bought separately and they are attached in no particular order.
Thanks about the /dev/zero remark, I didn't know that. >From what I've seen this afternoon, I'm starting to suspect a >hardware/firmware issue as well. Using Linux I cannot extract more than 24,5 >MB/s sequential write performance out of a single drive (writing directly to >/dev/sdX, no filesystem overhead). I tried flashing the BIOS to an older version, but that firmware update process fails somehow. Reflashing the newest BIOS still works however. It's a pity that I didn't benchmark before updating the BIOS & RAID firmware package. Maybe then I would have gotten decent Windows performance as well. It could even be an issue with the Seagate disks, as there have been problems with SD04 and SD14 firmwares (reported 0MB cache to the system). Mine are SD15 and should be fine though. I'm at a loss, I'm thinking about just settling for the 20MB/s write speeds with a 3-drive raidz and enjoy life... Which leaves me with my other previously asked questions: - does Solaris require a swap space on disk - does Solaris run from a CompactFlash card - does ZFS handle raidz or mirror pools with block devices of a slightly different size or am I risking data loss?
