First of all you will see a vast improvement in Performance of XP with 512Mb, or more, of system RAM, and you need a good amount of physical memory to run automatic background defragmentation, anti-virus scanners and anti-spyware scanners so that they don't disturb the system when you are working with it.
Defragmentation of Paging files, Master File Tables, and the Padding of Master File Tables, for systems running on NTFS, is vital for good performance. FRAG-SHIELD is part of Diskeeper 9 Professional and will do this job perfectly for you.
NOTE: The RAM in a computer can be shared by the Video system. (This is termed - Inclusive video RAM) So you can buy a computer with 512Mb of RAM (total) where 128Mb is used by the video system and 'only' have 384Mb available for the main system. Adding another 512Mb module overcomes this problem.
It is better to purchase a computer which does not share the main memory with the video system (Exclusive) so that you can have 512Mb (or more) system memory plus 128Mb video memory on the video card itself. So always ask if the video memory is inclusive (shared) or exclusive (not shared) with the main memory.
Another common example is: 256Mb main memory less 64Mb video memory = 192Mb of system memory. Not enough to get good performance from XP
NOTE: It is usually better to fit RAM in equal sized modules, 2 x 512Mb, 3 x 256Mb, 4 x 1024Mb and so on, depending on your use of the computer, the type and number of programs you are using, and the allowable maximum for the mainboard. With some mainboards this doesn't matter, as long as the RAM modules are compatible and of the correct type.

Example of partitioning an 80Gb drive: (Maxtor Diamondmax 7,200 rev/min with 8Mb drive-cache.)
What you do is up to you of course and if you have two physical drives Master & Slave, then so much the better.
80Gb (Decimal size) = 80,000,000,000 Bytes , divide by 1024 three times to give the Binary sizing:
78125000 Kb
76293·95 Mb
74·51 Gb
(10·0Gb = 10,000,000,000 Bytes (÷ 1024) = 9765625 Kb (÷ 1024) = 9536·74 Mb (÷ 1024) = 9·313 Gb)
Drive C: 10240 Mb (10·0Gb) Operating System & Programming. 2000 Min & Max paging file. (2048Mb on the drive.) (Drive Image Backup to CDRs or Data DVDs)
Drive D: 10240 Mb (10·0Gb) (My) Documents & Email Folders.
(Copy Backups to CDRs or Data DVDs)
Drive E: 20480 Mb (20·0Gb) Music only.
(Drive Image Backup, otherwise original Audio CDs)
Drive F: Remaining Drive Space. Archive, Video, etc.
(Archive Copy Backup to CDRs and/or Data DVDs)
Drive F: also has an Automated System Recovery (ASR) BackupC.bkf file for drive C: , to use with an ASR floppy.

All drives are partitioned & FULL formatted, directly from the Windows XP CD, to NTFS.
The installation uses Diskeeper 9 Professional, with Frag-Shield, to defragment the paging file and Master File Tables and to pad the Master File Tables when necessary.
NOTE:
Defragmenting the paging file and Master File Tables improves performance, as does running on 4096 bytes per allocation unit clusters, which is the default size for NTFS systems.
Fdisk and delpart.exe can be used to delete partitions which cannot be deleted otherwise.
