Rougeware SSD drives

Except for M.2 is sata unless NVMe is specified. you dont want SATA m.2 you want and need NVMe m.2

mSATA still maxes out at 560MB/sec. For most people that's enough. The perceived difference between mechanical SATA and SSD mSATA or SATA is huge. These huge numbers you see for Gen 4 and Gen 5 NVME are not perceived when you either use them professionally for swap or asset storage or when you copy across 100s of GBs of data. Those are not things most people regularly do. And these SSDs get very hot. I have a Samsung (Gen4) 990 Pro and even just idling it gets warm. My point was that all these devices are SSDs. People call the older SSDs (SATA) SSDs and the newer SSDs, NVME.

I am using idioms commonly used in the industry not trying to be technically accurate.

OK.

NVME is usually faster but doesn't have to be. Just like SATA HDD wasn't faster than IDE HDD. It still rings true that NVME isn't noticeably faster unless you're working on large amounts of data or using it for RAM.

SCSI connected HDDs were very fast back in the day. But not for random access. It was all about sequential read/write. SSD gives you much faster random access. And of course we all forget how cool SSDs were in laptops when they came out. You could go on a trampoline with your SSD containing laptop but not one with a mechanical HDD. Even earlier laptops would often have their HDDs heads crash when people tried to use them while walking.

NVME need not be faster (as a slow drive could be used or one which hasn't had proper TRIM performed or it could be thermo-throttled) but in general it is. Just going out by the max generational speeds here.
