“A Micron data sheet [PDF] describes the device as a 2016-vintage 64GB drive built on 20nm MLC NAND Flash sporting a SATA interface and offering three million hours mean time to failure.
We mention that last figure as it is well short of the 28,224 hours after which the M500IT puts itself to sleep inside Cisco devices, perhaps suggesting that it is Cisco’s firmware and/or OS at fault rather than any mess made by Micron.”
Wrong way round, but if it’s something Cisco side then micron should release a public reminder to those embedding their hardware not to do whatever Cisco is doing.
Work arounds and a fix is well known, also some of that kit is approaching eol so should only be running another decade.
