I'm talking about the SSL actually. I see them going for $80-$100 on eBay and those are SLCs. Still trying to figure out the meaning of the numbers in these HGST model numbers.@josh , I'm guessing you meant SML instead of SSL.
I did not dig too deep on the differences - based on the published specs the two drives are rated similarly. Based on initial testing impressions I'd say the SMM drives compare similarly to the SML drives. writes (with type 2 protection) seemed to be 15-25% faster in my very basic testing. (@ 4K - 64k RS.) My not very controlled testing environment showed without type 2 protection that writes were basically the same between the two drives +/- < 5%.
I do see some 400GB HUSML4040ASS601 on the bay ~$37.00 OBO - $40.00 but the majority of the SML drives do seem to be a bit more expensive than this deal. However the majority of the SMM on the bay seem to be in the ~$100.00+ range.
Given the either new or close to new state of the SML drives in this deal and apparently improved write performance I still believe this is a better deal.
quick performance test images attached, SMM, SML, included for comparison Samsung PM853T, intel P3605
SML drives had type 2 protection enabled at the time of testing.

I have a 2U 4 node Intel server (H2216 w/ S2600JF nodes) that has 4 2.5" drives per node. The controller node is an Intel 1U with 8 bays.How are you housing the drives? 4 node cloud servers? Looking for some hardware that justifies the cost of only 4 small capacity drives per node.
Having a little difficulty justifying full SSDs for home VM usage. Have you tried running these as cache drives for SATA/SAS?I have a 2U 4 node Intel server (H2216 w/ S2600JF nodes) that has 4 2.5" drives per node. The controller node is an Intel 1U with 8 bays.
I mostly use Linux VMs and containers with smaller images. This setup is a cost effective way to play around with Ceph, OpenStack, and other "cloudy" things for work. I couldn't afford populating all bays with larger drives and for the price the endurance/performance on the HGST drives can't be beat.
Use case? I assume the price/GB much lower for the 800Gs?I have from a while 12x HUSMM8080ASS200 (SSD800M instead of SSD1600M but with 800 Gb capacity)
I didn't really know which are performance difference between theses models but i'm really happy with theses (rock solid).
