You’re going to run into issues with your motherboard’s SATA or NVME (or PCIE) controller throughput well before you get close to actual RAM speeds.
Once you reach that bottleneck, the speed won’t increase anymore when you add more drives. The motherboard architecture just doesn’t support accessing any kind of storage device at that speed.
I did a (very) quick search and they should just sum up, so for example a raid of 2 sata SSD with 64gb that can reach 500MB/s will have a total speed of 1GB/s,
DDR3 ram can get up to 17GB/s so we would need 34 drives to get DDR3 speeds (not very fast BUT you would be the person with most ““RAM”” in the city without being a data center)
How many SSDs do you need for it to match the speed of RAM? Can I use this to make cheap RAM?
I just download more ram. Know your tech!!
