877740-B21 is a 240GB SATA read intensive SSD for 2.5-inch hot-plug bays: 6Gb/s, smart carrier, digitally signed firmware. The spare is 878844-001, the drive assembly number is 877800-001 and the HPE model number is VK000240GWJPD.
HPE's SSD QuickSpecs (version 19, August 2018) lists TLC flash and Gen9 and Gen10 support. Lifetime writes are 620TB, listed at 1.4 drive writes per day; sequential read is 500MiB/s and sequential write 185MiB/s. Random performance is 56,000 IOPS for 4KiB reads at Q=16 (maximum 64,000 IOPS at Q32) and 17,000 IOPS for writes (maximum 17,000 IOPS at Q1).
For servers, the ProLiant DL20 Gen9 QuickSpecs lists 877740-B21 among its 6G SATA hot-plug SFF smart carrier read intensive drives, and the ML350 Gen9 QuickSpecs lists it between 875509-B21 (480GB) and 868814-B21 (the other 240GB read intensive option). The version 19 SSD tables place it with the Extended options rather than the Recommended set.
That write speed is the practical difference from 868814-B21, the MLC 240GB read intensive option, which writes at 300MiB/s but is rated for only 372TB. Another 240GB read intensive SFF smart-carrier option is 875503-B21 (model VK000240GWEZB, spare 875652-001). Other HPE SSDs: HPE SSD drives hub.
