Hello everyone,
lately, we've had issues with buying SSDs that we use for
journaling(Kingston stopped making them) - Kingston V300 - so we decided
to start using a different model and started researching which one would
be the best price/value for us. We compared five models, to check if
they are compatible with our needs - SSDNow v300, HyperX Fury,SSDNOw
KC400, SSDNow UV400 and SSDNow A400. the best one is still the V300,
with the highest iops of 59 001. Second best and still useable was the
HyperX Fury with 45000 iops. The other three had terrible results, the
max iops we got were around 13 000 with the dsync and direct flags. We
also tested Samsung SSDs(the EVO series) and we got similarly bad
results. To get to the root of my question - i am pretty sure we are not
the only ones affected by the v300's death. Is there anyone else out
there with some benchmarking data/knowledge about some good
price/performance SSDs for ceph journaling? I can also share the
complete benchmarking data my coworker made, if someone is interested.
Thanks
Josef Zelenka
