How does this affect the old rule that 'ram is always faster than a spinning disk" and trying to keep your whole database in RAM ? It's not there yet, but this hard drive is approaching the speed of RAM.
- mrb 15y agoIt is far from approaching the speed of RAM. A medium-end Core i7 processor with triple-channel DDR3-1333 RAM has a theoretical peak bandwidth of 1333 MT/s * 3 channels * 64 bits = 32 GB/s. Compare this to this drive's 1 GB/s. And when considering latency, SSDs average tens of micro seconds, whereas RAM averages tens of nano seconds.
- GHFigs 15y agoAnother way of looking at it is that 1 GB/s is about the bandwidth of PC133 RAM that was commonplace about a decade ago.
