You need to forget about SATA here, no matter how much you love it... NVME is a new interface specification that uses the PCI-E bus... Btw, graphics cards use the same bus Samsung has found a way to use 4 lanes of data...hence the x4 spec... So let's stop with SATA, at least on this thread
The discussion was about M2 SSD over SATA ones and the supposed lack of any speed advantage fo the former, which is false. But maybe true if you have a cheap and slow SSD made with slow flash chips, or poor controllers. So what has to do with that a difference of 200MB/s over 2500 with the above? Sure the ssd makers tends to show their best results, is that a discovery? Is not the same you do when you meet a new girl or when you go for a job interview?
Thanks for deleting my post I posted for the benefit of Hadron-Curious and other curious users... On how a change in the size of a test data sample affects the results... In a forum, do all users possess the same level of knowledge ? Surely, this wasn't for your benefit...
@T-S, to simplify, there are two type of M.2: 1) M.2 SATA SSD (2 notches) 2) M.2 PCIe (NVMe) (1 notch) So saying "M2 SSD" over SATA is misleading.
