Sata vs nvme on pcie 2.0 x1?

[Cyber-Mav]

looking to add an extra drive, iv got a free sata port but also have a pcie 2.0 x1 slot that goes through the chipset (x470) available.

which would be faster or more ideal for me to go with?

PCI-E 2.0 1x = 5Gbps, so slightly slower than the theoretical 6Gbps of SATA.

Unless you've a need for older 2.5" drives in the future (e.g. reuse it for a retro PC or the like), then NVMe gives you more choice even if it would be bottlenecked

If you go m.2 then I'd double check the drive says it supports 1 lane, by the way, the sn570 says pcie2 1 lane is supported in the datasheet.

Ahh so not all drives support 1 lane, thats good to know and may sway things for the sata drive then

Yea agree with that logic.

Also one less cable, one less potential failure point, less mess in your case.

Will see whats going on black Friday

Got the nvme to x1 pcie card adapter on order.
I suspect sata 3 will be faster on sustained transfers vs pcie v2 x1 slot but guessing the nvme protocol will be better for random io stuff.
Also in future when i upgrade to faster boards with more native nvme slots and lanes the drive will get free speed boost.
