I'm afraid the 2242 requirement makes this much less of a slam dunk than it should be. Last time I looked for one, only the Toshibas were available as 2242 NVMe drives. (Many more similarly-sized drives are available, but they use SATA which won't work with this adapter.) I've been looking for an upgrade to my 2242 PCIe drive but they rarely appear, and usually by the time I find one you can't actually order it anymore.

It's a major upgrade, if your best storage is currently SATA 2; even if you have to select a relatively obscure SSD manufacturer.

  Which Thinkpad would that be? The switch over to SATA 3 happened between T410 and T420, coincidentally thats the same time they switched from Gen1 (PCIe 1.1, 2.5Gbps) to Gen2 (PCIe 2.0, 5Gbps). SATA 2/3 is faster than single lane of PCIe 1.1/2.0. example test on T410 https://pt.aliexpress.com/item/32260935657.html https://pt.aliexpress.com/item/32260935657.html 180MB/s max read out of a drive easily reaching 600MB/s in normal circumstances https://www.tweaktown.com/reviews/6961/plextor-m6e-black-edition-128gb-pcie-ssd-review/index4.html https://www.tweaktown.com/reviews/6961/plextor-m6e-black-edi... TLDR: its ALWAYS inferior to simply using SATA drive in HDD slot.

    I forgot about the ExpressCard being one lane of PCIe; what a waste. ExpressCard seems extra silly since it was often available on machines with USB 2.0, which was faster than PCIe 1 1x. No wonder it never took off for most.

      Single lane of pcie 2.0 is over 14x faster than usb 2.0 (realistic 35 MB/s in optimal circumstances), pcie 1.0 is still >7x faster.

        This, the 480Mbit/s rating for USB 2.0 is bits, not bytes. USB2 theoretically caps out at 80MB/s (realistically much much lower) whereas even PCI-E 1.1 can hit 250MB/s (2.5Gbit/s before 8b/10b encoding overhead) in a single lane.

  No doubt. I'm not questioning the value... even one lane is better than SATA2... just the ability to actually get hands on a part that fits into this adapter. I think the mod would be much better if there were a way to have it protrude out of the laptop with a 2280 form factor drive, so that more parts would be usable in it.
