#2Impressive. First question that pops into mind is how long the rebuild time would take if one of these failed in a RAID. I can imagine it'll take a while.

It takes 8 hours 20 minutes to write 15TB over 500MBps. Why would you want to stick one of these in a RAID though?
..it would be more like Redundant Array of Prohibitively Expensive Drives.
(I'll show myself out)

article says 1200MBps.. so more like 3.5 hours.

~4 hours to read/write a whole drive ain't too bad. Of course there might be other bottlenecks in your raid, or you only reserve so much speed for rebuild, but the drives size is not the problem.

I thought RAID and SSD were a terrible combination. As if both drives do exactly the same writes at the same time, chances are they will fail at the same time. Plus most RAID controllers don't support TRIM.
Has the thinking changed?

A Raid 5 could work, since you are not writing the same data. You would need a hardware coprocessor to handle generating the checksums at 4GB/s though.

Yeah, the statistical chance of the same thing happening on both drives is the same, but the chance of it happening at the same time is pretty low.

#9It's awe inspiring to see fifteen terabytes of solid state storage in that little box.

#10Bye bye mechanical ...
