1)RAID is two or more drives synced in an array. There are different types of arrays like Raid 0, 1 Raid 5, 10 as well as spanning a single volume across several drives
Sata is Serial ATA over the ide type drives being Pata or Parallel ATA being the more commonly used type in use. Sata I drives are still found in limited systems while Sata II is very much the standard people have been running with for several years now. Sata III drives with a faster speed rating are more recent and now are seeing new boards that only see Sata III ports.
2) Unfortunately you are out of luck as far as XP if that model series never saw any XP drivers written to start with. With premade laptops and desktops and the fast chahge over to newer model lines the present version(s) are those that see support until a new line for the next comes out. The manufacturer of the laptop(Dell) or the board manufacturer if you find that out "may"? while not usually have XP drivers while boards for laptops and premade desktops are generally custom ordered specific for one brand.
In other words.... Pot Luck on finding any! Upgrading out of Basic into one of the more full featured editions of 7 would provide more options for you rather then trying to stay with an OS companies have pretty much dropped entirely. January makes XP 10yrs. old! That's ancient history for hardware manufacturers!
