What Are The Obsticles To Making SSDs From DRAMs

[BruhthaKuga]

I know that DRAM need power to keep it's data and that it's more expensive but I believe that today we have small batteries that will keep DRAM data for years to come.

Could it be viable to have a DRAM storage device that is half way between HDDs and RAM? At start up it loads the OS and installed apps from hard drive and then the system uses it as the HDD?

Hey! What if they do that on the mobo, have RAM slots for a RAM drive? SSDs will not be viable for desktops with those devices.

They exist.

Yikes! Why would anyone spend $1500 for 4 gigs of storage?

Said storage will be fast as hell

 

[Tews]

Simply because they can...

 

[stevieray]

Would it be much faster than an SSD?

Chuckle.

Texas Memory Systems - Products - RamSan-20

I think this thing ballparks around $18k

 

[Antman]

If you need a bit more...
Virtual Optics: RamSan-500 2TB Solid State Raid

$150K per TB.

This would rock for a server, or a cluster, but unless you're a bazillionaire .... yikes!!!:shock:

How about using flash memory instead of RAM(of course modified to last longer)
No boot, Instant ON!
I meant that you press the power button and after 1 sec you see the Welcome screen!

Too rich for my blood.
I think I'll stick with life in the slow lane.

old and satisfied

If only they can get NANDs to erase page by page instead of block by block so that TRIM will not be necessary then I can die old and satisfied with da. . .I mean speed.

I know! I know! It's impossible

 

[BruhthaKuga]

promising

Now this looks very promising but also expensive, it also should've had a regular HDD backup instead of a CF backup. Check out the Tech Report article:
