Pros: Comes with management UI so you can configure your disks without having to boot into the BIOS every time

Cons: - Froze my computer whenever I did sustained transfers at first, went to their site and updated the BIOS, now freezes my computer only once in a while - Management UI doesn't have support for sending email via SSL, which all smtp servers require for authentication these days, so send email on error event feature is worthless - Controller is flaky. I put in a set of 1 TB WD disks, worked for a few months, then the UI tells me my disks have failed. I swap them out for disks that were working fine in a different chassis, it tells me those disks are inconsistent. I buy a new set of disks and put them in. A day later, controller tells me the disks are inconsistent.

Overall Review: If you want decently reliable storage, avoid this.
