Theres 3 serial port connections, several USB, and a PCI FPGA, and PCI-E NI DAQ. Run a modern host and virtualize Win XP under that host, providing that piece of hardware is controlled over serial or USB and you can get pass-through to work from the VM. Plus you can snapshot it, since all hardware goes belly up on occasion. Performance should be nearly the same, the overhead to run Hyper-V is minimal, and you can then migrate that VM to new hardware in the future if you have to. If this piece of equipment has to stick around forever, eventually you're not going to be able to get hardware that supports XP very well. However, I might look into something like deploying a free Hyper-V server and XP within that, to virtualize the hardware.
Depending what the old hard drive is and what the new SSD is, you're probably looking at 5x faster reads and writes or so, so even if it degrades to half performance (I think it's more like 80%), you're still 2.5x faster than you were before. Performance will degrade, but you're still getting a massive upgrade due to it being an SSD vs. Unfortunately, this piece of equipment is one of a kind of incredibly expensive, so I cannot do anything about it needing XP. If I put an SSD in there, what exactly happens when I fill the disk and then empty it? Will performance degrade or is emptying the disk enough to fix it? Looking online theres all kinds of things about how exactly SSDs interact with XP. I'd like to replace its dead magnetic hard drive with an SSD as file access times are somewhat of an issue for it (it basically acquires large amounts of data that must then be copied off). Stupid question, but I need to fix an older piece of equipment with a dead hard drive that must be controlled via a Windows XP machine (so no TRIM).
