We're using our 6501 in a 19'' rack with additional fans for 5 years and it
still runs fine with the initial batch of dual 64 GB ADATA mSATA. We also
use additional heatsinks on all visible chips for better heat transport.
Machine also runs in a controlled temperatur and humidity environment.

</span>I think you should be fine with most disks. I never had any<br>
compatibility or configuration problem, just some hardware bad luck.<br>
<br>
The only real recommendation I have is to buy two SSD of different<br>
brands, and run them in mirror mode (with ZFS or RAID). As Eric<br>
mentioned, be aware that the two Mini-PCI Express sockets are shared<br>
with the mSATA sockets, so if you use two mSATA disks, you can't use the<br>
Mini-PCI Express sockets.<br>
<br>
A quick summary of the problems I had:<br>
- Bought my net6500 in december 2011.<br>
- Original Transcend TS16GMSA300 (in mSATA slot J6) crashed in september<br>
2013<br>
- No mirror, had to get data from backup. Took me over a day.<br>
- Replaced with two Intel SSD, SSDMCEAC030B3, mirror mode.<br>
- Intel SSD #2 (in mSATA slot J6) crashed in october 2014 and september 2015<br>
- Changed position of the SSDs in the mSATA slots<br>
- Intel SSD #2 (now in mSATA slot J5) crashed in october 2015<br>
- Got replacement disk from Intel<br>
- Intel SSD #3 (in mSATA slot J5) crashed in november 2015<br>
- Replaced with Kingston SMS200S330G SSD<br>
- Running fine with an Intel SSD #1 + Kingston ever since.<br>
<br>
As one of my colleagues (and storage expert) mentioned: If you get two<br>
equal disks of the same brand, type and batch, they are more likely to<br>
fail at roughly the same time. Just get yourself two different brands of<br>
disks. Less likely that you have a duplicate failure at the same time.<br>
