Subject Commit log on USB flash disk?
Date Sat, 16 Nov 2013 14:12:59 GMT
Our hosting provider has a cost effective server with 2 x 4TB disks
with a 16G (or 64G) USB thumb drive option. Would it make sense to put
the Cassandra commit log on the USB thumb disk and use RAID0 to use
both 4TB disks for data (and Ubuntu 12.04)?

Anyone know how long USB flash disks last when use for a write heavy
workload like this?

Please tell me if this is a really bad idea.

Our alternative is to use one 4TB disk for commit log and one for
data. Of course this will give us only half the space.

Thanks
David
