Use RAM on expansion card as harddrive?
« on: March 06, 2008, 08:51:46 PM »

A few years back (2000/2001) I read in a magazine about a PCI card which you could populate with RAM modules, max 4GB if I remember correctly, and then use as a fast (and quiet) "harddisk" to put the OS on. In order to prevent the information from being erased from the RAM on shutdwon, a power supply was connected to the back of the card.

Does anyone know if a card like this exists today (perhaps PCIe) for the consumer market? I´ve been thinking about it lately and thought it would be atleast fun to try out, if it exists/is available..

I saw one at Newegg no more than 3 years ago. Can't remember any brand/manufacturer details, but it used a SATA interface. It was supposed to be *really* fast. 4GB capacity, maybe?

Whoa, thats cool! 16GB was more than I hoped for.. Do you know where to get it?  :-D

There are lots of solid state disks around, commonly 16-64 GB, most with SATA but some IDE still around.

You might find link to dealers here

They are 40x faster than hard disks in read access times, but are 5x slower than hard disks in write access times and therefore at least 2.5x slower in read and write balanced IOPS. IOPS (Inputs and Outputs Per Second) is Intel Corporation's measure of how many files a drive can serve (output) and receive (input) per second.

Yes, but not with the specs of Hyperdrive....

8 DRR1 DIMM slots, each of which can take registered ECC DIMMs up to 2GB on the 16GB(max) version (no on-board RAM included).

Seek time is 1100 nanoseconds read/250 nanoseconds write.

A good hard disk can do around 40,000 stops and starts at 40 degrees centigrade (Hitachi/IBM Deskstar 180GXP). The HyperDrive4  doesn't mind how many stops and starts it does because it has no moving parts.

XP installs on a HyperDrive4  in around 7 minutes, rather than the 40 minutes that it takes to install on a Hard Disk. The limitation is the CDROM drive speed not the HyperDrive speed!
It fires up Windows XP in 2 seconds from the splash screen to the desktop with nForce4/5 Mobos. It fires up Windows 2003 Server in 2 seconds (although in both cases it is hardware polling and device driver timing loops that take up most of that 2 seconds). So it is “instant on” and gives you an “instant desktop”.

A Solid State DDR drive. Please do not confuse flash SSDs with DDR SSDs. They are entirely different devices. Sure they are both solid state, but then so is a lump of concrete.

4 HyperDrives in RAID0 88,000 - 94,000 IOPS 395-413 MB/s STR (HDTach)
4 HyperDrives in RAID0 104,000 IOPS 445 MB/s STR (IOMeter)

Price:
One hyperdrive alone, no DDR modules:
HyperDrive4  (Revision 4) - 16GB max
£1195 $2390 (US)

But it is the ultimate harddrive :-D

You're probably thinking of the Gigabyte i-RAM.  
Time to move on.  Bye Amiga.org.  :(
