Is it possible to get a fast HDD and use it as RAM?

You can get a card which connects to a PCI slot on your motherboard which basically as many RAM chips on it with a small battery which means it works in the same process and speed as RAM, but obviously the storage is permenant, unlike standard RAM isnt.

Only 2 bad things really with them, the price and if the battery goes flat. But i guess more reliable than a standard HDD as no head or anything.

He's asking if you can use a HDD as RAM, not RAM as a HDD.

The hard drive already acts as a sort of ram, it's called page file. But hard drives are alot slower than hard drives, a standard sata hard drive has an average througput of about 50MB/sec, with a burst of around 150MBps. Standard DDR400 has an average throuput of about 3.2GB/sec, so you can see the difference in speed.

But i presume he is askng this as wants to improve performance?

My guess would be he wants to get alot of memory (like 20GB), by buying a 20GB hard drive and saving alot of money that buying 20GB of RAM.
 
Hehe, he should see the difference in my grandparent's computer. It was an old Celeron 700MHz, 64M RAM, and Windows XP. They said it took 6 minutes to boot. I removed the ram and stuck 256M into it, and it'll boot in under a minute now! I still don't understand why it took quite that long before(I had JUST reformated it for them, so it was clean) but whatever...HUGE difference. Oh yeah, and that was with the pageing file disabled.
