I ran H2testw again to confirm capacity falsification. Watch the video. As it approaches 500GB, the write capacity decreases and eventually becomes impossible to write to. Then an error will appear. This SSD is a 2TB product, but it cannot write 500GB. Check out another video. This is a tool to check NAND of SSD. This SSD only has a 512GB capacity chip. For these reasons, this is a capacity-disguised SSD. I would like a refund or a refund. This item is eligible for free returns.
