Better than a NAS
Pros: Runs 64bit Linux (Ubuntu) without a hitch, booting from a flash usb stick for the initial installation. Nice form factor. Pretty quiet.
Cons: It's a bit tricky to install additional memory (I expanded the memory to 4G.) The hard-drive bays are not hot plug and have a bit of a cheap feeling.
Overall Review: This machine replaced my ReadyNAS NV+ and this machine supports all its features from a stock Linux distribution (with the possible exception of the "xraid" automatic expansion of RAID arrays). Plus you can run your own backup scripts etc.
failed the worst possible way
Pros: Wide range of network protocols. X-RAID is a nice function to incrementally expand the capacity of a RAID set.
Cons: Firmware doesn't handle RAID failures well (see other thoughts below). Mediocre read/write performance. Web interface sluggish, especially when the firmware is doing things like resyncing or expanding a volume.
Overall Review: On my system, after a year one disk went bad and the firmware thought it was a different disk that had failed. It marked the good disk as needing a resync and when the disk that was actually bad failed again, all data was corrupted and irretrievable. Even though the bad disk was still working intermittently (with extra cooling) the raid state was hosed beyond help. (Yes I had backups for the more important data.)
