If your motherboard supports only 2GB of RAM then at least get 2GB installed in it. However, 64-bit OS gives extra boost after 4GB because 32-bit Windows XP supports 4GB RAM but can utilize only upto 2GB to 4GB.
In RAID 0, both of your harddisks will be join and give you double space and with almost double read speed. In that sense, if you add another 500GB harddisk and create RAID 0 (from BIOS) then it shall be:
500GB + 500GB = 1000GB (RAID 0)
Consult your motherboard’s manual on how to create RAID 0 from BIOS. It’s a major boost of harddisk speed. However, as in any harddisk (single or RAID 0), if a harddisk will get physical damage then you’ll loose data. Therefore, even you have only one harddisk always backup your data.
