As the X200 was released in 2004 it would be a safe bet that your motherboard is BIOS rather than UEFI based.
Windows cannot boot from a GPT partitioned disk under a BIOS system, which means you are limited to less than 2TB for your boot disk.
I'm not sure if there are other limits at play, but for a single disk system this limit means that anything above 1.5TB is potentially wasted. I believe SATA has always had support for 48-bit addressing so as long as you have a SATA disk then the theoretical hardware disk limit is in the petabyte range.
For multi disk systems I do not believe this should be a problem. You can have a small MBR boot disk and a large GPT partitioned disk for storage. Windows can boot from a small disk, and doesn't need BIOS support in order to use a GPT disk. My system is old and is currently set up with a 240GB SSD and 3TB HDD.
On a side note: please ditch Windows XP. It is unsupported and potentially insecure and is loosing program support every day. It may have limits I am unaware of due to its age, but as a minimum it appears that XP without any service packs is limited to 128GB.
