SATA full speed

[GPCExplorer]

Hi, I have a laptop which I'm going to replace its old HDD for an SSD. There's only a classic SATA connector and no m.2 port for NVME SSDs (so NVMEs are theoretically not an option). I was wandering if I could pull all of the SATAs capable speed by using an m.2 to SATA adapter and an NVME SSD. I imagine that bigger bottlenecks could be the adapter and the SATA driver of the laptop and that it's all about combining the right SATA driver with the right adapter. Any feedback will be grateful :).

A regular sata drive like the mx500 or wd blue already maxes out sata. Sata has been maxed out for years now by even garbage ssds. No need for silly adapter stuff.

NVMe and SATA are different communication protocols. You cannot adapt SATA to NVMe with a cable, it won't work.

 

Just get a good SATA SSD and you'll max out SATA's bandwidth.

Pretty much all SSDs nowadays run at ~550MB/s read/write, which is very close to the (theoretical) limit of SATA, which is 600MB/s.

No need for fance NVMe adapter stuff, which won't work anyway as SATA and NVMe are not compatible in the slightest way.

The communication protocols are totally different for SATA and NVME and they are not compatible or interchangeable.

 

With SATA you will hit a wall around 500MB/s, NVME's can go a lot faster especially the gen 4 version. But they also required dedicated PCIE lanes.

 

In short SATA works with SATA interfaces and NVME's only work with PCIE interfaces.
