Thanks for the sheet. I need a low space disk for my use case (around
240GB). Do you have any suggestions with M.2 and capacitors?

Easy, 883 has capacitors and 970 evo doesn't

Is this a reply to Paul’s message from 11 months ago?

The PM1725b is interesting in that it has explicitly configurable durability vs
capacity, which may be even more effective than user-level short-stroking /
underprovisioning.

Hi. How do you say 883DCT is faster than 970 EVO?
I saw the specifications and 970 EVO has higher IOPS than 883DCT!
Can you please tell why 970 EVO act lower than 883DCT?

Disabling write cache helps with the 970 Pro, but it still sucks. I've
worked on a setup with heavy metadata requirements (gigantic S3
buckets being listed) that unfortunately had all of that stored on 970
Pros and that never really worked out.
Just get a proper SSD like the 883, 983, or 1725. The

Hi,
the Samsung PM1725b is definitely a good choice when it comes to "lower"
price enterprise SSDs. They cost pretty much the same as the Samsung Pro
SSDs but offer way higher DWPD and power loss protection.
My benchmarks of the 3.2TB version in a PCIe 2.0 slot (the card is 3.0!)

Hi,
I am running a nice ceph (proxmox 4 / debian-8 / ceph 0.94.3) cluster on
3 nodes (supermicro X8DTT-HIBQF), 2 OSD each (2TB SATA harddisks),
interconnected via Infiniband 40.
Problem is that the ceph performance is quite bad (approx. 30MiB

Hello,
think about migrating to a way faster and better Ceph version and towards

Hello,
think about migrating to a way faster and better Ceph version and towards
bluestore to increase the performance with the existing hardware.
If you want to go with PCIe card, the Samsung PM1725b can provide quite
good speeds but at much higher costs then the EVO. If you want to check
