GDDR5 SSD

[HectiKCookiE]

are there and ssd's that use memory chips higher than ddr2 and if so what are they?

wut. when did ssds use volatile memory?!!!! or graphics memory from your title.

[Chucky401]

gddr5 is soley graphical memory so no there is not, nor ever will be, a gddr5 ssd.

soory its not like ddr2 ram its ddr 2 nand flash

There are SSDs that use ram. Generally they have a backup battery and many times have backup storage, like a CF card. they also for best results would use ECC ram. These are called DRAM SSDs they are now very uncommon since flash SSDs have entered the market offering similar performance since they are both restricted by the same SATA busses.

I had one from Gigabyte way back in the day that took DDR ram and used a SATA I connection. It plugged into a PCI slot for power and had backup battery, where if it went out you lost everything.

Actually all SSDs have a DRAM cache, usually 256MB-1GB DDR2 or DDR3 But if you meant for the main storage, no, GDDR5 can't maintain data without power so is not practical for this type of usage.

There is also no such thing as DDR2 NAND flash, not sure what you're on about

not mention GDDR stores data in a different format suitable for graphics, etc..

Oh and there are DDR3 Variants available. These are generally from the X58 days when SSDs were just getting legs. These will likely have CF cards and will more than likely be SATA II. Though there may be some SATA III as that started around that time as well with those shit marvell controllers that only preformed better than a Intel SATA II controller on sequential transfers. Who knows there might still be a company making new ones of these because it was niche in the first place to I have to imagine there is still some demand somewhere. I imagine they would still be DDR3 though since DDR4 is so new and costly.

Toss in the fact that GDDR5 is actually based on DDR3 tech and its eve more confusing as to what the OP means.

Also it should be noted that sandforce drives dont have this cache if I recall and actually use some of the nand, but more of it because they needs larger cache, likely for the compression.

I WISH THEY WOULD MAKE GDDR5 RAM DISKS THAT PLUG INTO THE PCI-E X16 SLOT AND STORE THE DATA ON YOUR HARD DRIVE WHEN YOU SHUT DOWN!!!!!!

They make ddr3 which out be equivalent. PCI-E is possible now with newer controllers but a HDD would be much to slow to backup something like that. You would at least use some sort of flash that is cheaper than ram. Now days a SSD would likely be the cheapest. You want to get something high end though as its going to sustain a ton of writes. Preferably it would have power loss protection as well.

I doubt this will be made though as demand is lower than ever.

But but but GDDR5. And they can add a 6-pin power connector like a graphics card so you don't loose data when you put the computer to sleep (or hibernate).

[TheGeekster]

But if you shut the computer down... you'd lose it... Google RAMDISK, if you've got spare ram you could mess around with one of those

Still would need a backup battery, heck all motherboard's have one.
