Have had some good experiences with ST10000NM0156-2AA111
Also running with EC but using RBD for slow storage for VM's, have had good performance for what id expect for 10TB drive's and EC.
I would definitely say getting helium drives helps VS standard air filled when you get to the 8TB+ drives.

Dear Ceph users,
I’d like to get some feedback for the following thought:
Currently I run some 24*4TB bluestore OSD nodes. The main focus is on storage space over IOPS.
We use erasure code and cephfs, and things look good right now.
The „but“ is, I do need more disk space and don’t have so much more rack space available, so I was thinking of adding some 8TB or even 12TB OSDs and/or exchange over time 4TB OSDs with bigger disks.
My question is: How are your experiences with the current >=8TB SATA disks are some very bad models out there which I should avoid?
The current OSD nodes are connected by 4*10Gb bonds, so for replication/recovery speed is a 24 Chassis with bigger disks useful, or should I go with smaller chassis? Or dose the chassi sice does not matter at all that much in my setup.
I know, EC is quit computing intense, so may be bigger disks hav also there an impact?
Lot’s of questions, may be you can help answering some.
Best regards and Thanks a lot for feedback . Götz
