"Caveat emptor ..."1.5 starson by Bobby_Pix
Pros: Does what it claims.... but slow, but proprietary,
Cons: Nothing can restore the data if there is a hardware failure. Guaranteed to loose your data, sooner, rather than later. There is no official recovery software. Takes DAYS to remap drives during failures . Better have a GOOD UPS.
Summary: Nice toy, minimally built with low spec for what some may consider a critical device. This should never EVER be a back up device, just a big pool to manage data SLOWLY and immediately back up... errr. SLOWLY.
