I am searching for an answer about using SSDs drivers, which are build for the mainstream. Afaik ceph uses for its marketing to buy cheap disks for entprise ready storages. But I cannot find any details or tests about this.
E.g. if you take a look at the 1TB SATA 2.5" e.g. SanDisk Ultra 3d or Samsung 960evo both are pretty cheap right now to build a fast storage array with ceph
But if I read on, there are a bunch of limitations mentioned for storage arrays (for SANs or RAID-arrays) to avoid cache on the drives, to ensure a high DWPD. So does this also match do ceph? If considering this facts the price for the same sized SSD is about factor 3 to 5 more expensive between mainstream and enterprise SSDs.
So considering from economical perspective, I could buy at least 3 times more drives with mainstream SSDs compared to the enterprise grade SSDs for RAIDs or SAN storages.
Can someone tell me, if the mainstream SSDs will work well with ceph on production environments?
What endurance per named SSD drive can be expected?
