...and move to RAMDisks. I have a problem with my 840 Pro and I downloaded CrystalDiskMark to run some benches. I had some fun benching my 1GB 2400MHz RAMDisk in the meantime:

Dat speed...

Why do i always get blue screens? Why not a red one for a change?

That latency though. Extremely long start up and shut down times.

Plus $10 a GB is a pretty big turn-off for 99% of people.

Never mind that all the cpu work required to move that much data is so high that by the time all these points are all said and done a ramdisk only feels faster than a SSD for a few specific uses.

Try using Fancycache, you can cache your drives using your ram less time for loads, and transfer speed oh man.

 

Also great for recording, if your drive is slow as balls and you need to cap raw footage to it for some reason

drop an 8GB or higher cache on it and it will do the trick.

GPU - Asus AMD Radeon 6950 Direct CU II 2GB |

Seasonic 1000 W Platinum | Cooler Master 690 ii Advanced | Asus VE248H + VE248Q

This is on a 28GB RAM disk. Im using 1600mhz Corsair Low Profile Vengence memory.

This was from a Samsung 840 EVO with the Rapid mode activated.

 

and while I am here:

The left shows my 6TB RAID0 with a caching SSD using Intel Intilicache on a z77 motherboard. Right shows the SSD alone. It is a Samsung 840 Evo

What happens when that cache fills up? BAM. Poor random performance.

yes, im sure intel would have left something this obvious in their software. I imagein that it frees up stuff in the cache to make sure that only relevent stuff is kept.

 

I have had it for a few weeks now and it still hasnt slowed down. I am using a 64GB Cache on a 120GB SSD.

I mean the cache on your RAID array. If the cache on that is that large then you'll have no problems.

What happens to the data if you turn off your PC? :D

there used to be PCI/PCI-E devices that could store RAM DIMMs to be used as a RAM disk. They had a battery on them to keep the data.

But doesn't the interface change reduce the speed?

Why do i always get blue screens? Why not a red one for a change?

They even started to tinker with battery backed up RAM, not sure if it got off the ground but the RAM Disk would stay in tact and no need to reboot just sleep then wake and all is as you left it. I lost the name of the company...

I roll with sigs off so I have no idea what you're advertising.

 

This is NOT the signature you are looking for.

What would you do with the RAM disk when you shut the computer down.  You have to write that data somewhere.

Desktop: Intel Core i7-6700K, ASUS Z170-A, ASUS STRIX GTX 1080 Ti, 16GB DDR4 RAM, 512 GB Samsund 840 Pro, Seasonic X series 650W PSU, Fractal Design Define R4, 2x5TB HDD

Hypervisor 1: Intel Xeon E5-2630L, ASRock EPC612D8, 16GB DDR4 ECC RAM, Intel RT3WB080 8-port RAID controller plus expansion card, Norco RPC-4020 case, 20x2TB WD Red HDD

Other spare hypervisors: Dell Poweredge 2950, HP Proliant DL380 G5

Laptops: ThinkPads, lots of ThinkPads
