The storage is SSD based. I use a Samsung 840 EVO 256 GB via ACard ARS-2320S SATA to SCSI converter. This results in the following performance:

Comparing this to the R12000 300 MHz system, the R5000 300 MHz O2 is slightly slower with small files in the diskperf benchmark. It's a little bit faster with the bigger file sizes. The higher CPU power of the R12000 seems to help the SCSI performance of the system when accessing lots of small files.
From time to time the Samsung 840 EVO SSD forgets its volume header. The workaround looks like this:
