Do you mean Serial ATA150 (SATA)? Are you sure your motherboard even supports SATA drives? If it is an ATA150 drive, not SATA, it's pointless because it'll never be able to transfer data at that rate. Increasing your RAM to 512mb would be a good thing, but since your CPU runs at 533FSB, you really should have PC2100 (DDR266) running in dual channel mode. Does your board support dual channel? I suggest you do some research before buying the wrong stuff Asus A7N8X-X 1800+ @8x210mhz 512mb PC3200 Ti4200/8X 128mb WDC 60GB
