Thoughts on the HyperX Predator PCIe SSD as a SLOG?

[depasseg]

Just saw this, and thought it might make a good slog. Fast, durable writes, priced somewhere within reason.

240 GB ($230) and 480 GB ($460) capacities.
1,400 MBps and 1,000 MBps of sequential read/write speed.
130,000/118,000 random read/write IOPS.
Endurance rating of 1.7 Drive Writes Per Day (DWPD), up to 805 GB of writes per day over the 3-year warranty period.

Thoughts?

It's Kingston, so expect those values to be halved a couple of months after the review samples have gone out.

Good to see more M.2 stuff, though.

The endurance is okay, though most people probably won't like it because it's Kingston. I am curious if freenas would post a PCIe drive like this. I have no need for a slog, but if you end up buying this, or something similar, please follow up with your findings.

I know people are already using these for slog devices: http://www.hgst.com/solid-state-storage/enterprise-ssd/sas-ssd/zeusram-sas-ssd

ZeusRAMs are SAS SSDs, so quite different from the PCIe/NVMe stuff (which works on FreeNAS 9.3 with the Intel P3700 series). Downside on many m.2 drives might be the missing power capacitor, so the data written to the SLOG can be corrupted or lost.

Apart from that, Samsung just released the 951 NVMe SSD.

I hope someone's got the burn center on speed dial, because that's at least second-degree.

Aside from it being Kingston and therefore earning an automatic stink-eye from me for their recent bait-and-switch-fest, I can't find anything on power fail prevention which is kind of critical for an SLOG device.

Well, looky what Intel has: An NVMe (or SATA express) based S3700 with power backup:
