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

- rasz 7y agoWhich 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.
- microcolonel 7y agoI 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.
- rasz 7y agoSingle 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.
- yttriumtyclief 7y agoThis, 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.
- hoistbypetard 7y agoNo 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.
