wondering what I should get.
Are people getting intel 330's for l2arc and 520's for slog?
For the slog, you should look for a SLC technology SSD which saves unwritten data on
power failure. In Intel-speak, this is called "Enhanced Power Loss Data
Protection". I am not running across any Intel SSDs which claim to match these
requirements.
- That shouldn't be necessary. ZFS flushes the write cache for any device
written before returning
from the synchronous request to ensure data stability.
Extreme write IOPS claims in consumer SSDs are normally based on large write
caches which can lose even more data if there is a power failure.
