When you’re in the market for a new SSD, you’re probably focusing on the PCIe interface (PCIe 4.0 or PCIe 5.0) and the read/write speeds. Most people choose a reasonably priced PCIe 4.0 NVMe SSD for their PC, and the one spec they might check is the read/write speed. That’s where the research ends in most cases, but it’s important to know a few other things about the drive you’re buying. Whether it has DRAM or not, how long it can last, and what type of NAND it uses are vital questions that should be answered before you part with your money.
