<div dir="ltr"><div class="gmail_extra"><div><div>Personally, I think SSDs are overkill for recording storage.
The cost/GB ratio is still orders of magnitude higher than HDDs, and the
benefits you get from a SSD (fast random access) don't really match
what you need for recordings (decent sequential performance). Even the
slowest HDDs these days are still fast enough to record and watch
multiple simultaneous streams, since they are still large sequential operations, just interleaved with each other. Also, the bitrates required for recording and playback are relatively low compared to the sequential throughput of HDDs available today.<br>
<br></div>Hosting the
OS/system/database/metadata on an SSD does make more sense however since
those items will benefit much more from the higher random throughput,
and do not take large amounts of space.<br><br></div>If you're worried
about losing data from drive failures, I think backups and/or drive
mirroring are a better method to managing that.</div></div>
