I don't trust flash, so I am being cautious, but...
I am in the process of replacing my old (and I mean old) basement server
with a new one. I have the base box mostly set up and am moving on to
the mail VM.
Anyway, I bought a little mSATA 60GB card, and so far I am glad I did:
- I can boot. The Ubuntu installer didn't understand the larger block
size on the external 4TB drives I bought, so who knows how hard it would
have been to make them bootable. I installed onto the SSD and added RAID
1 external storage later. I have / on the SSD, but not /var nor /home,
and certainly no swap.
- It is fast. Compared to my previous toys, his new computer is damn
fast in general, but the SSD is also marvelously fast.
Worries:
- Flash can die with no warning and no recourse. I will be making a
copy of the flash and keeping it on another medium. Maybe this board can
boot from the SD slot it has? Maybe I just use a slow USB stick.
- Flash hates writes. It can do some writing quickly, but be stingy
with it. I plan on not writing to this device much. I don't think I have
any hot files on it.
- Flash hates getting full. I have a 25GB partition for the OS, which
I think I can keep mostly empty. I have a second a complete copy in a
second partition I can revert to if I break something. And the little
extra is sitting mostly blank. I think wear-leveling happens across the
whole device, all of the sectors I can refrain writing to are a benefit.
