consistent, functional 1TB usb drive?

[Velcro Leaf]

I'm trying to get off tape drives and move to USB drives for backups, however circumstances are making this impossible.

Does anyone have a suggestion for a known 1TB external USB drive, powered 
through the USB cable, that consistently works with FreeBSD, and has for some time?

I've gone through half a dozen models of such drives and each time I find one that works properly on each of our servers, I try to buy a few more to make a complete cycle.  Invariably, however, I can no longer purchase the same model, or I can get the same model, but it is invisibly different at purchase-time (eg, with new firmware that doesn't work with FreeBSD).


I've tried to work through the quirks process with you guys, but it hasn't been successful, and eventually I suppose it's not considered enough of a problem to fix, probably because in a few weeks there will be a brand new version that doesn't work, in a different way.

I know that these drives are all tested with Windows before shipping, and that's why they work with Windows, but is there any plan, on either the hardware or FreeBSD side of things to deal with this issue?  I've been working on and off on the problem for about a year, and if anything, things are getting worse.
