There is a lot of good engineering in the Thumper. There is a lot of clever engineering in the Backblaze. The comparison states a lot of valid points on power distribution, drive reliability and RAID throughput.
I see Backblaze will learn a lot from building their storage systems and future versions may be much better, but this one cuts too many corners for me to feel confident it will have the same kind of reliability I would recommend.
What amazes me most is the use of desktop-grade hard drives. Not because they are sloppily built, but because their performance requirements are so different from a server environment.
