ZFS on USB drives (I know it's a bad idea, but how bad is it really?)

I was already jittery at “USB enclosure” and then you just had to go and bring up WD Greens… twitchtwitch

I still really, really don’t advise doing that. The best thing to do with 1-2TB WD Green disks, whether they still work or not, is just to e-cycle them. BRAND NEW usb hard drives are about $60 apiece. Refurbished 8TB non-USB enterprise drives are also around $60 apiece.

This, in turn, means an entire stack of eight 1TB WD Green drives is worth significantly less than $60–it provides less space, worse performance, more points of failure, and FAR worse mean time BETWEEN failure than that single refurbed HGST 8TB, with roughly an order of magnitude higher heat generation and energy consumption.

So I mean, yeah, on the one hand you could say I’m triggered, but on the other hand you could say I just really want people to realize what their choices mean and what other choices are available. Building a stack of 1TB WD Greens into any kind of multi-drive array in 2024 isn’t much different than building five 1.44MiB floppy drives into a RAID5 array was for me in 2004–a hilarious way to play around with garbage, but not a thing that should be considered “not-garbage” in any way beyond artistic, once complete. :slight_smile:
