I am adding another 500 GB SSD to my PC and unfortunately, my motherboard does not support NVMe. It does not have an M.2 slot but it does have an available PCIe 3.0 slot.
I am looking at the two different drives.
WD Blue 3D NAND 500GB PC SSD - SATA III 6 Gb/s 2.5"/7mm Solid State Drive - WDS500G2B0A
WD Blue 3D NAND 500GB PC SSD - SATA III 6 Gb/s M.2 2280 Solid State Drive - WDS500G2B0B
Obviously, with the M.2 I would need an adapter like
SYBA SI-PEX40110 M.2 PCI-e To PCI-e 3.0 x4 Card
or
StarTech.com PEX4M2E1 M.2 Adapter - x4 PCIe 3.0 NVMe - Low Profile and Full Profile - SSD PCIE M.2 Adapter - M2 SSD - PCI Express SSD
Both drives are listed as 560 MBps Read / 530 MBps Write and with SATA III being 750 MBps max it should not be a bottleneck.
However, I do know that M.2 has some advantages like being connected to the motherboard and therefore reducing latency.
What are the advantages of the M.2 and is it worth it?
Also, does anyone have any experience with PCIe to M.2 adapters?
You can look up all products mentioned on Newegg.
