M.2 SATA better than 2.5 in SATA?

[Jae Tee]

So I watched the bellow video 2ice and have seen the same conclusion. For most things other than sequential Read and Writes NVMe has no benefit to sata. Problem is the video omitted M.2 sata drives, and I have a hard time believing (without any proof) that an M.2 sata would be the same or even worse than 2.5 sata. So my question is: Is there any benefit, in terms of speed, to the M.2 form factor that you wouldn't get from a standard sata cable, while also avoiding the pitfalls of NVMe, for day to day use?

No benefit.

No need to manage cables is a benefit for me, but that's it.

Due to controller design (what sits between the PCI_e slot and the NAND flash), with M.2 SATA drives you're stuck with the same amount of bandwidth as you'd have over a standard SATA cable. Even if there's a small/minute improvement in delay/latency due to shorter traces, it'd be virtually undetectable in day to day use for a consumer.

 

In other words, the only difference is the physical form factor. Performance is ~the same.

Realistically that's all im looking for

There is no speed difference between SATA 2.5" vs. M.2 SATA (if we're comparing the 'same' SSD's like 860 EVO M.2 vs 2.5").

The main benefit in such a case would be no need for any cables.

The disadvantage is that typically when using an M.2 (SATA) SSD, multiple SATA ports will get turned off.

Unless you're doing something like high speed electronic stock trading or tracking prices in a database for a large company where constant accuracy is critical you are not going to notice the difference between M.2 SATA and standard SATA.

 

If you want M.2 SATA for the convince of the form factor that's about the extent of the realistic benefits it comes with.

SATA is SATA. The differences are within mArgin of test error

If that video is the one I think it is, none of the testers could definitively tell the difference - SSD's are all basically the same; if you're in the 1% that needs the ultimate speed, you'd be getting the hardware bought for you.
