Pass
It supports RAID 0, 1, 5, 6 and 10 and JBOD arrays.
Snore. Nothing fancier? ZFS? LVM? Bueller?
Multiple RAID volumes are also supported but because it uses the EXT4 file system the maximum for any volume is 16TB.
Ext4 supports volumes up to 1 exabyte, but only with a larger block size. So what is actually unsupported is using a non 4kb block size on ext4. 16TB sounds a lot, but its not - buy this, put 4TB disks in it, wait 3 years, upgrade the disks to 8TB disks and you are over that 16TB limit.
Price: £235 (unpopulated) RRP
Just shy of £60 per bay..
I am probably slightly beyond the target audience - too tight and too demanding. My current home storage server has enclosures with 32 bays (just 16 populated atm) for around 28TB of ZFS storage, for which I paid roughly the same as the Thecus..
