It is $139 at this deal, but from Amazon AU, meaning you can get next day Prime delivery if in Melbourne. Has also been A$137.55 via AMZN-UK/AU
NVMe drives may work in a regular SATA M.2 slot at limited speeds, but this is best for someone with a newer NVMe capable laptop or motherboard. I tested my SN750 in the secondary M.2 slot and it got 1GB/s.
Best part of Amazon AU Prime item means you basically get minimal questions, paid return slip with full refund in the first year.
What is $155,77?
