    If you're concerned with speed, then RAID6 seems an odd choice, it gives
    the same usable capacity as RAID10, it's slower at reading and slower at writing, it will burn up your SSD write endurance sooner ...

    Yes RAID6 can survive *any* two SSDs failing, where RAID10 can survive
    any one SSD failing or *some* combinations of two SSDs failing, but as
    we all know, RAID is not a ...

    600 writes is impossibly small

    As SSDs have moved from SLC to MLC to TLC the number of write cycles has dropped and dropped, by an order of magnitude per generation, now we're
    at QLC some only have an endurance of 100 writes per cell ... the only
    thing that stops them dying as soon as you look at them is the increased capacity of the device.
