The combination of RAID0 redundancy, an ext4 filesystem, a Linux 4.x kernel, and either Debian Linux or Arch Linux has been associated with data corruption.
El Reg reports EXT4 filesystem can EAT ALL YOUR DATA
Fixes are available, one explained by Lukas Czerner on the Linux Kernel Mailing List. That post suggests the bug is long-standing, possibly as far back as the 3.12-stable kernel. Others suggest the bug has only manifested in Linux 4.x.
[...] This patch for version 4.x and the patched Linux kernel 3.12.43 LTS both seem like sensible code to contemplate.

I have some tools running RAID0 WD Raptor drives - they were built before SSDs were readily available and the policy is to maintain the original hardware profile if possible.
Don't get me wrong - this is a silly point of failure for a million dollar tool, but legacy is important!
