Yup, many early-mid 2010s Lenovo Thinkpads have an externall expresscard slot: X230, T520, W520, T530, W530, T540, W540... 1 entire lane of PCIe 2.0 (3.2 Gbit/s ... ~300MB/s) bliss! But more seriously, people actually used to use these for external gaming GPUs way back when. For Qubes, on some of these models, the slot is very helpful: you can add an additional USB 3.0 root hub for external devices that can be mapped independently, even if you can only get about half-throughput from it. B PS - Also, some internal laptop slots for wifi/etc. are mPCIe...but using them for other purposes generally means leaving the laptop disassembled, which means...well...why use a laptop? -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
