>8TB SATA SSD

[Tich77]

Hi there. Is anyone aware of a source of >8TB SSDs, 2.5" format SATA interface?

Ive just upgraded my Synology 923+ NAS from 8TB to 16TB HDs, and would have preferred to have gone to SSDs... but cant find a source. Has the world migrated to NMVe and forgotten about SATA?

You would be getting into enterprise level drives and looking at U2/U3 format most likely, you wont find SATA larger than 8TB SSDs yet.

Unless you need the performance of SSDs....the HD's should be fine?

They would be if I was using 1gig ethernet... but I'm using 10Gb, reads are ok, but writes to 5 drives in SHR-1 are being pushed to keep up. Sustained transfer rate is just under 1GB/sec. SSDs would be better. And of course... power!

U2/U3 also unlock higher speeds up to 6.5GB/s. 16TB drives are hovering around $1200/ea.

Your Synology DS923 is CPU limited and even with all SSDs you aren't going to get 1GB/s.

Obi Wan, this is your only hope.(SA4/SI4)

DOH! Senior moment. Its a 1621+ I had a 920+ and was going to upgrade to a 923+ except the 1621 seemed the better option. It does do 1GB, but it is not constant... ie will hit 1GB, drop to 980MB, rise to 1GB... not quite sawtoothing.

My old 920 could exceed 100mb/sec, but the throughput would fluctuate (albeit rarely droppping below 110mb).

The nice-to-achieve-but-not-essential is a reduction in power consumption, mechanical wear (always a trade-off between high hours-on figures from always-on operation, vs lower hours-on but massive increase in power-on cycles from power-down when not in use operation), and [potentially] higher/improved sustained disk throughput.
