These are labeled as NETAPP X319_S16437T6ATE (Part Number MZILT7T6HMLA) but they are actually Samsung PM1643 (and also printed on the label). These 7.68TB SAS SSDs have been running in my NAS for years, and only managed to run them down by 1% of their life! These also have power loss protection circuitry. Note that they are SAS3 drives, not SATA. Free insured shipping, even to international buyers. I cannot provide warranty on them, but they are guaranteed against a DOA situation if notified within 30 days of sale.
