I bought one of these from the same seller last week-ish when they were still $150.
The SMART output if anyone is interested:
It has a few accumulated write errors, so I don't know that I would consider it "grade A". However, it passed my pre-clear tests and didn't accumulate any more write errors, so I put it in service.
Recently (yesterday), I flashed an updated firmware from Cisco; now the drive thinks it's the HUH721010AL42C0, as the 4200 and 42C0 firmwares were identical. See my post here: https://forums.servethehome.com/ind...gst-hdd-ssd-firmware.22381/page-4#post-316580. It's too early to tell whether it's solved the power-on reset errors on delayed read I've been seeing, but I'm running a RAID scrub, which typically results in a few drive timeouts, so if that finishes without error I'll declare it good.
