Frequent question: Which is faster SSD or DDR4?

Which is faster SSD or RAM?

RAM Speed. RAM is orders of magnitude faster than an SSD. … The theoretical maximum speed of RAM is in its PC number, so a module of PC3-12800 memory can transfer 12,800MB/sec–roughly 30 times faster than the real world performance of an SSD.

What is faster than an SSD?

NVMe can deliver a sustained read-write speed of 2000MB per second, way faster than the SATA SSD III, which limits at 600MB per second. Here the bottleneck is NAND technology, which is rapidly advancing, which means we’ll likely see higher speeds soon with NVMe.

Will SSDs ever be as fast as RAM?

Absolutely not. SSDs use flash memory which is much, much, much (did I mention “much”?) slower than RAM. They need to use flash memory because that’s the kind of memory which retains data without any power.
