Replace HDD in Sony HAP Z1ES with an SSD


I'd like to replace the (original) HDD in my HAP Z1ES with a solid state drive of perhaps 2.5 TB capacity. I'd appreciate any advice/caveats/taboos?

One note, the HAPZ1 will only recognize an internal drive up to 2TB.  My understanding is a USB drive can be larger, but I haven't tried that.
Thanks for your help. As it turned out, I had the work done by Modwright with their upgrades. I can barely bring myself to turn it off! 
Very easy to do with the instruction on the web sfseay mentioned . Takes about 15 minutes . I did it as well .

sfseay,

Have you tried SSD over 2TB? I was hoping to make it 3-4TB, but it seems it is not an option.
