I am currently moving from a ZFS array to a Ceph cluster based storage system, however in order to not lose alot of capacity to mirroring in Ceph I need to implement a caching system to allow for erasure encoding on the CephFS portion of the cluster. Because I will be using mediocre speed drives for the main storage the writes need to be absorbed by the write cache (hence 250GB cache drives). Does anybody have recommendations for 250GB+ SSDs that can absorb alot of writes and are preferably cap backed? (I typically write ~2TB per day to this filesystem in ~100GB chunks)
