Hi all, Thanks for all your follow ups on this. The Samsung SM863a is indeed a very good alternative, thanks! We ordered both (SM863a & DC S4600) so we can compare.
Intel's response (I mean the lack of it) is not very promising. Allthough we have very good experiences with Intel DC SSD's we still want to give them a chance. Hopefully the SCV10111 firmware has fixed the issue! (The changelog for the firmware doesn't mention any major problem fixed though, only 'bugfixes') Will let you know the results (probably in a month or two). Kind regards, Caspar 2018-02-23 0:18 GMT+01:00 Mike Lovell <mike.lov...@endurance.com>: > adding ceph-users back on. > > it sounds like the enterprise samsungs and hitachis have been mentioned > on the list as alternatives. i have 2 micron 5200 (pro i think) that i'm > beginning testing on and have some micron 9100 nvme drives to use as > journals. so the enterprise micron might be good. i did try some micron > m600s a couple years ago and was disappointed by them so i'm avoiding the > "prosumer" ones from micron if i can. my use case has been the 1TB range > ssds and am using them mainly as a cache tier and filestore. my needs might > not line up closely with yours though. > > mike > > On Thu, Feb 22, 2018 at 3:58 PM, Hans Chris Jones < > chris.jo...@lambdastack.io> wrote: > >> Interesting.
