Appears to be a Black Friday deal. Not the lowest, but maybe someone can take advantage of it.
Samsung V-NAND 3bit MLC (TLC), 2.5 inch SATA III, Read up to 560MB/s, Write up to 530MB/s, 98K/88K IOPS, 2,400TBW
I'd also keep an eye on the one sold by Amazon UK because yesterday I saw it for $303. I thought I had to ask the mods to reactivate an old deal. In the process of that, it climbed up to $463… Sorry guys.
