In fact I have 3 in daily use, one as the boot drive for a milling machine, and 2 as development drives on an (was rpi3b, but its now an rpi4b) and while the usb2 interface for those speedy drives had a high failure rate, replacing the adapter with a different brand has revived one such adata drive 3 times, and it will serve as the compile scratchpad for both a 4.19-preempt-rt kernel, or a fresh copy of linuxcnc's master branch. Takes the wear and tear off the u-sd the pi boots from. In short, since I put the pi's swap on one of those drives, I have had zero drive or u-sd trouble in 2 years. Theres a 120G kingston in the mill, no spinning rust in either the mill or the Sheldon Lathe.
