    Phoronix: Western Digital RE4 1TB SATA Enterprise HDD

    Benchmarks up this afternoon are of a Western Digital RE4 WD1003FBYX, an internal enterprise hard drive, being tested from Ubuntu 13.04 with the Linux 3.8 kernel. This Linux disk drive comparison was done with an EXT4 file-system and other disk benchmarks are available from different solid-state and traditional rotating hard drives.

    I wonder how dose it perform as a member of linux software raid?
    Last time I used RE2 disks I had to replace them all with standard desktop edition.
    All of them still work fine in windows, however they had a nasty habit to keep failing from MD mirror without any apparent reason.

      Two 1TB WD1003FBYX hdds in linux software RAID-1, ext4 with default settings over LVM. Modern E3 xeon system. Tested with sysbench. You can use the commands below and sysbench to test your system for comparison.

      Regarding falling out from array. What system are you using? Chances of cougar-point sata bug maybe? http://jakkul.blogspot.com/2013/01/h...tem-might.html

      Code:

        It was few years back, when WD introduced raid edition series. I've jumped on wagon and fell off hard. Don't touch anything that have a fancy suffix in the model name
