The S3500 can be had for $1.00/GB now these days. If you don't need
the write durability or the all-out write performance of the S3700,
it's a great deal.
I do have to wonder if hardware RAID with a BBU can help with write
amplification when on SSDs. Though since RHEL/CentOS 6.5 supports trim
in software raid, that could be a bigger win.
