Up for sale is, an SK hynix PC300 256GB PCIe Gen3 x4 NVMe SSD in the M.2 2280 form factor, model HFS256GD9MND-5510A BA, serial EJ74N070310304830, EUI ACE42E7190033D63, firmware 20005A00, carrying Dell part number 0XHFF7 with a week 16 2017 date code. CrystalDiskInfo reports the drive as Good at 98% health with only 2% of its rated endurance consumed, available spare holding at 100% against a 10% threshold, and zero media and data integrity errors and zero error information log entries recorded. Lifetime totals come to 49,166 GB read against just 9,214 GB written across 33,537 power-on hours and 141 power cycles, with 65 unsafe shutdowns logged — the very high hour count paired with low write volume and a read-heavy access pattern points to a drive that sat in an always-on system doing light, mostly read work rather than one that was worked hard. It supports the NVMe 1.2 spec with S.M.A.R.T., TRIM and volatile write cache, is rated DC +3.3V at 2A, and uses the standard M-key M.2 2280 interface found in Dell and most other systems with a PCIe Gen3 x4 NVMe slot.
