SATA2 is really old. The SATA revisions are:
SATA1 - 1.5Gb/s
SATA2 - 3.0Gb/s
SATA3 - 6.0Gb/s
SATA3 is often referred to as SATA6G although because of 8b/10b encoding overhead you a SATA6G link maxes out at 4.8Gb/s
There are many NVMe SSDs that use 4 lanes of PCI-E Gen 3 which is just under 32Gb/s
If you read this review you can see read speeds of 3500MB/s which is 28Gb/s or just under the 32Gb/s limit.

I am using lowercase "b" for bit and capital "B" for byte
- StavrosK 7y agoHmm, maybe my disk is using SATA3 then, I have an Evo and a not-ancient motherboard. However, I'm wondering whether I'll see a practical difference in my day to day workloads, which is mostly web development and no gaming.
- barrkel 7y agoIMO - not really. You might if you're memory constrained and you're doing analysis of logs or something like that.
- StavrosK 7y agoThat's what I figure as well, thank you.
- numpad0 7y agoNVMe is always electrically PCIe and always M.2 or PCIe card form factor for PC users. If it’s 2.5” it’s 100% SATA. If it’s M.2 then 50:50. Idk but what I’ve heard is anecdotal small files I/O and boot time speed up stories so webdevs might appreciate it on next builds. The premium is dropping fast anyway.
- beatgammit 7y agoI was a little annoyed that I didn't notice a big difference, but then I figured that I'm bottlenecked by other parts of my system. It's still a win because it's stuck to the case instead of hanging out in a bay, so my computer is a bit more neat.
- account42 7y agoPlus, there are already PCIe 4 NVMe SSDs.
