779176-B21 is a 1.6 TB SAS solid-state drive running at 12 Gb/s, a 2.5-inch SFF drive in a SmartDrive Carrier from HPE's Mainstream Endurance (ME) Enterprise Mainstream line, generation H2. HPE rates it at 66,000 random read and 62,000 random write IOP/s, with sequential speeds of 1,000 MiB/s read and 565 MiB/s write. HPE gives a 15 mm height, standard SFF size, 512-byte logical blocks, 9 W power and a 0 to 60 degrees C operating range.
For endurance, HPE rates the 12G SAS ME Enterprise Mainstream H2 drive at 1.6TB as 29.2 PB of lifetime writes, equal to 10 drive writes per day over five years. HPE also lists the same 1.6TB drive without a carrier as 779174-B21.
HPE's spare is 780436-001, a 1.6TB hot-plug SAS SSD with a 12Gb/sec transfer rate, 2.5-inch SFF, Mainstream Endurance, Enterprise Mainstream and SmartDrive Carrier, supporting Gen8 servers and beyond only.
HPE solid-state drives lists other 12G SAS and SATA drives, such as the 800GB write-intensive 873355-B21 and the 400GB mainstream-endurance 691866-B21.
