It depends on the speed of the ram and whether it was in dual channel or not.

A single stick of DDR4-2133 would be capable of 17066.67 megabytes a second.

2 sticks would be double that or 34133 megabytes a second.

The above are theoretical maximums that you probably won't sustain or even reach without a perfect environment


I found this ramdisk benchmark from 2012.

It doesn't show his setup but we can assume its at least DDR3

From my 17 gigabytes a second with a single stick of DDR4-2133 I can calculate that he was using DDR3-1254 or more likely DDR3-1066, rounding down to the nearest standard frequency.

Of course he also could have had a really old ddr2 system being used in dual channel mode.

But you get the idea.

So, from that data the Crystaldisk Mark 4KB QD1 for DDR2/DDR3 RAM was between 564 to 1068 or 2 to 4 times faster than Optane. So am I correct in assuming DDR4 is 6 times faster than Optane and Optane is 6 times faster than a SSD for this metric.

the problem with sata in this respect is overhead and latency not throughput.
290MB are not an issue for Sata in its current version but the IOPS are.

The main difference between SATA and NVME is less signaling overhead allowing much lower latency between calls. 500.000 IOPS is out of Satas reach, so a drive like that does not make much sense (at least not until market permiation allows for "low end" optane drives).

Other than cost, which is now far better than early -enterprise- versions, my only complaint is it's size... There's no way to have it on M.2... according to AnandTech, the controller alone is larger than 22mm M.2 module. and it's power consumption is higher than that of NVMe...

And the 2.5" form factor is only available on 240GB, the 480GB only available in PCIe form factor
