Everspin Technologies, an Arizona-based company, has become the first in the world to supply MRAM, shipping their own ST-MRAM (Spin-Torque Magnetoresistive Random Access Memory) chips to select customers. This non-volatile storage claims to be up to 500x faster than current SSDs, but comes with a similar price tag - up to 50x more expensive.
Let's talk specs - we're looking at 1.6 billion IOPS, and "up to" 3.2GB/sec of bandwidth with latency measured in mere nanoseconds. To compare, most decent SSDs are the mid 100k IOPS with just under 600MB/sec in throughput, with latency measured in microseconds, rather than nanoseconds.
