Hi, nowadays we all know that the ERC/TLER capability is very important for the use of spinning drives in RAID systems because, especially for recent hard disks, the recovery time in case of media errors could exceed kernel timeouts and possibly kick off the entire drive from the RAID set and, in turn, lead to a fault of a RAID5 system upon a subsequent error in a second drive. But in the case of SSD drives (where, possibly, the error recovery activities performed by the drive firmware are very fast) does the presence of the ERC/TLER capability really matter? Is the same scenario from the spinning drives case actually even probable or only theorical? Thank you for the considerations and evaluations you want to express. Gianluca
