Hi bros, lspci -v shows this: Fakeraid is generally on motherboards, but a lot of add in cards have it too. I presume that the ASUS chipset is supported natively by Windows, like most common hardware, but I haven’t actually looked it up.

Sign up using Facebook. Saturday, December 29, icy10r The 4K Thread scores went up by approximately a factor of four for both reads and writes, yet the sequential reads went up by a factor of three. RAID1 is mirroring and no striping, and it works fine with no extra effort.

ICH10R RAID support in Ubuntu

The devices comprising the RAID show up as discrete, independent disks. And also, I like to monitor the hard disk status without stopping the machine, it hosts some web sites.

After banging my head against this a while longer, I thought I’d change tack and see where it led. Tags drivesataseagateubuntu Thread Tools. If it’s just not possible I’d like to know so that I don’t sink more time into a lost cause.

Surely if it’s hardware raid ubuntu shouldn’t be able to see individual drives, and if it’s software I’d have needed to install some software on windows? The GB drives are faster than 64GB drives simply due to memory density.
