SanDisk ULLtraDIMM DDR3 400GB SSD Enterprise Review

[4Strings]

*long whistle*

 

This would bee pretty "useful" on older x79 systems. I mean, for most cases, you don't really need 64GB of RAM. You could populate, say, a single channel with 16GB, or even two channels with 32GB of RAM, and then populate the rest with these.

 

That either 1.6TB/32GB or 2.4TB/16GB Storage/RAM ratios!

[RH00D]

Where does this go? Does it go where I think it does?

 

That's what she said. But then I said, "No, it goes where you think it shouldn't."

[Mastaline]

it go's into your server because it has more dim slots. your ddr3 duel channel mother board generally wont have the free slots unless you want to run single channel ewwww no don't od that

My 8 slot X99 would like a word with you

[Aniallation]

So basically RAMdisk

[Scheer]

I have no proof, but I'm 99.99% sure you aren't going to be able to just throw this in a random board that has DDR3 slots. It will likely be dedicated slots with a controller on the motherboard, but again I have no proof just being realistic here.

 

 

I know that would be really good for servers (but they already have arrays of SSD's as RAM's), but isn't the m.2 jus better for us, "normal consumers"? This can achieve speeds ~8gigabits, while m.2 can go up to 10gigabits.

And don't tell me you would notice 10 microseconds.

 

The 8 gbps is a bottleneck of the product, not the RAM slot, so in the future you will likely much faster versions of this if it takes off, when high capacity NAND catches up.

 

10 ms adds up when its going back and forth hundreds of tens of times per day, not where a normal user would notice it, but I'm sure there are specialized applications out there where people are drooling over the reduction in latency.

 

 

So basically RAMdisk

 

RAM disks are volatile, meaning they will loose all of the data on them when you power the system off, this does not. Its also nowhere near as fast as a RAM disk. Typical RAM disks are 8 gigaBYTES per second and beyond, this is 8 gigaBITS, so around 1/8th the speed but it varies depending on your RAM.

[flibberdipper]

Oh my god. You could watch 8K porn with this and not have to worry about the storage being too slow.

[Exotath]

Want. Make for DDR4 and give.

[lnxpro]

IBM has had the eXFlash SSD DIMMs in servers for almost a year now... This is the same thing. nothing new here.

[Faceman]

Very cool and innovative.  Will have to do some more research, but this is something I am interested in buying!

[Weak1ings]

Wonderful but if they become too tall...  Airflow will die.

[sevs]

Do you also need another slot for normal ram?

[Netto]

Whaaaaaaat, would ram liquid cooling work on these?

[Termander]

Wow thats pretty fast. can you boot from it?

[BloodWithIce]

so it's a ram disk...?

[chungpruoi1998]

So this counts as an SSD and can be used to store stuff like any other drive but is in a ram slot or it counts as a stick of ram that does ram stuff?

It's a ram stick with a SSD on it. It still has ram memory, but only 2GB )

[Kjellstad]

OK, what the hell. can this be used as RAM? or does it just take up a DIM-slot and gives you 400 GB of storage?

[Valli]

Is linus going to make a video on it??

[That Norwegian Guy]

Remember, this is SanDisk, the company that will push any broken unripe technology to market just so it can 'beat' Kingston and Crucial to being 'first', while the two latter actually do their job and refine shit before selling it.

 

Buying first generation SanDisk stuff is pretty much the dumbest thing you do.

 

Every 1st gen of memory card, especially compact flash

SanDisk "readycache" SSD (google it, a true trainwreck of titanious proportions)

This SSD RAM DIMM will no doubt also be shit, probably either lasting like 3 months in a system, or incompatible with 90% of hardware, or just lying about performance etc. countless possibilities.

[kidddd66]

This..... Is..... Awesome...
Linus should review this 

[theodoro]

I don't understand why someone would want to put an SSD into the RAM slot. What else will we see?  DDR4 GPUs?
It is cool, but not something i would call innovative. 

[ManWithBeard1990]

Before this can actually be used new processors with a second memory controller will have to come out. Otherwise the system can't tell the difference between ram and storage. And that's bad, m'kay. Either that or you'd configure it as a 'ramdisk' in BIOS, but it'd be nonvolatile

[DuckDodgers]

Many people here don't seem to know that in the early days of PCs, the processor bus was pretty much universal interface for connecting not only the RAM, but a wide range of peripheral devices and controllers. Having a separate (local) high-speed peripheral bus for long time was a kind of luxurious feature.

 

In fact, every device that has to "talk" to the CPU has a reserved address space in the system's memory, where the device's driver communicates (commands, data, interrupts, etc.) to the rest of the system, no matter now it is attached. It all goes through the memory.

ddr3 pfffft

[Mr.Sommer-Hansen]

other than what will it cost.. i'll say:
