yeah we're very interested in trying toploaders, we'll do a test rack next time we expand and switch to that if it goes well.

w.r.t. testing the main thing we did was try to buy a bit from each supplier a month or two ahead of time, so by the time we were doing the full build that rack was a known variable. We did find one drive lot which was super sketchy and just didn't include it in the bulk orders later. diversity in suppliers helps a lot with tail risk
