Scott, thank you for your topic. I am planning new installation and comparing between RAID 10 and RAID 5 on ssd drives. What do you think about stripe size and TBW for two types of raid? Do you know what size of blocks will be written on disks if service (sql for example) writes 8Kb on volume. For raid10 I think it will be two 8K blocks on mirror disks. But for RAID 5 it will be two blocks with size=stripe size and may be 32 or 64K. And in raid5 configuration TBW limit will be reached faster.
