Hello Kai,
there are tons of bad SSDs on the market. You cannot buy any brand without having some bad and maybe some good models.
Here as an example some performance values from Intel:
Intel SSD DC S4600 960GB, 2.5", SATA (SSDSC2KG960G701)
jobs=1 - iops=23k
jobs=5 - iops=51k
Intel SSD D3-S4510 960GB, 2.5", SATA (SSDSC2KB960G801)
jobs=1 - iops=10k
jobs=5 - iops=22k
The Samsung PM863a you mentioned is quite a good SSD for general purpose and cost efficiency, unfortunately Samsung seems to no longer produce this drive and try to sell the PM883 instead. Performance seems to be near the same, and maybe it will be a good choice too.

_______________________________________________Hi everyone,
I have an Intel D3-S4610 SSD with 1.92 TB here for testing and get some pretty bad numbers, when running the fio benchmark suggested by Sébastien Han (http://www.sebastien-han.fr/blog/2014/10/10/ceph-how-to-test-if-your-ssd-is-suitable-as-a-journal-device/):
Intel D3-S4610 1.92 TB
--numjobs=1 write: IOPS=3860, BW=15.1MiB/s (15.8MB/s)(905MiB/60001msec)
--numjobs=2 write: IOPS=7138, BW=27.9MiB/s (29.2MB/s)(1673MiB/60001msec)
--numjobs=4 write: IOPS=12.5k, BW=48.7MiB/s (51.0MB/s)(2919MiB/60002msec)
Compared to our current Samsung SM863 SSDs the Intel one is about 6x slower.
Has someone here tested this SSD and can give me some values for comparison?
Many thanks in advance,
Kai
