Gee, another item of useless anecdotal evidence directly attributable to cheaply manufactured cards from a third world country and no direct correlation to a flaky chipset design. > * 3ware 9650SE-8LPML-Sgl - I thought money would solve the problem, > but I didn't realize that you can't use an expensive RAID card to > access existing data on the disk Ahh.. > * Supermicro AOC-Saslp-MV8 - I thought it would be a perfect match > given my Supermicro motherboard, but also gave me lots of errors > during heavy I/O and this experience seems to be confirmed by other > users in this thread Oh dear.. Yes, the mvsas driver has been noted to be somewhat problematic still. I hope you're not a betting man. 3 for 3 is not a great record thus far. On the up-side the 7042's have been as solid as a rock.. and _fast_ for the last couple of years. Marvell worked with Mark Lord and the result was a workable version of the sata_mv driver. Shame they don't do the same with the mvsas code. Additionally, I migrated two arrays from the Marvell7042 controllers onto the LSI based "IBM" controllers configured up as JBOD and they just worked. No initialisation or reconfiguration required at all. Brad
