10+ years ago I tested moving some (ancient at THAT time) Celerons[0] to SSD drives. It made absolutely no difference, because the CPU is too damn slow. My own rig was on A64 X2 4200+ (with no less than 8Gb of RAM at any time) for years, with Vista since 2008. I don't remember when I migrated it to SSD (perhaps ~2012-2014?) but I noticed a great improvement in QoL, though it wasn't instant. Years later, somewhere around 2016 I "upgraded" to G2010[1] and despite everything else (well except DDR2 => DDR3) were the same (including OS and the system drive on that SSD) I noticed performance increase in both boot-up and everyday operations. You still need a good IPC to actually push any meaningful amount of data. While OP's T9400 is not Presscot bullshit[2] it is still an ancient shrunk down Merom, ie just the firsts of the Core CPUs. > Which would mean 4 GB/s max And the memory is just 6.4GB/s max. Still, in 2022 this is probably the simplest way to add a decent amount of fast storage for a such ancient machine.
