People don't seem to understand that IOPS is a meaningless measure from a practical perspective.
It is just a weird way to express throughput. An SSD that loads 4KB at a time has 64 times less IOPS than RAM that loads 64 bytes at a time assuming both have the same bandwidth.
- Dylan16807 4y agoThe average fetch is not that big. IOPS and GB/s are both very important numbers. From a practical perspective, the IOPS of RAM is critical for running programs. And if you're doing anything other than big file transfers, an SSD plugged into USB 2.0 at 35MB/s will beat a hard drive on USB 3.0 at 200MB/s. Even better is IOPS at queue depth 1, IOPS at queue depth 16 or 32, and max bandwidth.
