Up to 16TB of centralised storage for your small -business needs.

The rebuild / build times on this is somewhat a worrying issue (price seems decent but the lack or certain features makes this a no go)

RAID 5 and 16TB is probably a really really bad idea, the chance of data loss is quite high.

Yeah, raid 6 or 51 should be a minimum at this level.

Definitely - It would be madness to use RAID0 for 16TB, even if it was just a temporary video framestore - I feel the review should have made this much clearer, especially as the benchmarks were testing RAID5. Unfortunately with the limited number of bays it makes level 6 or 51 somewhat pointless/unfeasible.

Rebuild time is not surprising and inevitable given the amount of data that has to transferred across the bus, especially in this case with a consumer-level SAS/SATA backplane and controller. I have an 8 x 4TB array at home and about 6 days is what it took to build.
