i bought a few smr drives, knowing they were smr. they were cheaper, a lot cheaper than the same amount of space in cmr. used only for static media storage, so that’s not a big deal, really., but holy hell was it slow getting stuff on them initially.
i have a few self-powered externals that are also smr (quite common with those as they use 2.5in notebook hdd). when those things have to start shuffling bits around and rewriting tracks, sustained write speeds fall well under what even usb2 can send.
it’ll be covered on screen 73 of the ‘agreement’ required to use the device.
