I would like to install a M 2 hard drive in my computer.
I am aware that the inspiron run on GT 2 mode.
But if I buy an ssd that only uses two pcie lanes, will it be running at full speed since its only half the speed of a full x4 pcie lane drive?
Would appreciate any help!
Why not just buy a full performance M.2 NVMe drive - chances are the drive will outlive the system, and you may wind up using it in a better system in the future?
It's equally true that higher performance drives generally use more reliable flash chips. If you buy a low-end drive, you'll be compromising not just performance but potentially reliability.
I'd go with a less expensive first-tier M.2 SATA drive over an NVMe drive from a lower-tier manufacturer. Remember - your data is on that drive. The last thing you want is a turbocharger thrown onto a cheap engine not built to take it.
