FakeFlashTest

FakeFlashTest is quick, in fact a lot quicker than even RMPRepUSB, and of course a thousand times quicker than H2testW.

However, I have found that FakeFlashTest does not work on drives over about 1.5TB at all. I provided 6x brand new drives:

2x PNY NVMe 2TB (QLC, purchased from large reputable retailer) 2x Chinese NVMe 2TB (QLC, purchased from large China site) 2x Chinese SATA 2TB (QLC, purchased from large China site)

All of these reported failures starting right at the same point--1.5TB. It didn't matter if it was connected via PCIe x1 or x4 adapters, or via USB. While tests with RMPRepUSB on the same drives took much longer (10-20 minutes) reported fine. Two of them were tested with full 12 hour H2testW tests and tested fine as well.

I don't know what is likely sending it to some type of integer overflow causing it to wrap around.

As 2TB drives become more common, hopefully others can post if they are seeing the same issues?

v1.1.1 quicktested my unformatted new 480 GB SSD in 53 seconds. That's great, but it didn't show how fast the writes and reads were and recommended another test using H2testw. If I were to use H2testw as suggested, what's the point of FakeFlashTest's Empty Space test?
