WebJun 25, 2024 · SSD drives don’t have to spin into position, which means they can randomly access data in a fraction of a millisecond. 2. They have I/O performance levels several times better than their HDD cousins. 3. Lower energy consumption and better reliability because of their lack of moving parts are also significant benefits of these drives. WebPhase-change memory - Wikipedia Phase-change memory 16 languages Phase-change memory (also known as PCM, PCME, PRAM, PCRAM, OUM ( ovonic unified memory) and C-RAM or CRAM ( chalcogenide RAM )) is a type of non-volatile random-access memory. PRAMs exploit the unique behaviour of chalcogenide glass.
