The M500 was released over 2 years ago a lot has happened in the SSD
market since then.

New controller, new NAND-Chips (M500 - 20nm, MX200 - 16nm).

I will take a very close look on the performance though and will
definitely compare with non-ssd-journals.

Thanks for the heads up, the nice thing about those 250GB SSDs is..
I can just put them into desktops or notebooks if they are not suited
for the cluster.
