That’s 7x over SATA SSDs and as much as 35x over spinning HDDs! NVMe drives, on the other hand, provide write speeds as high as 3500MB/s for Gen MB/s for Gen 4. For comparison, a 7200 RPM SATA drive manages around 100MB/s depending on age, condition, and level of fragmentation. Via that connection, most SSDs will provide Read/Write speeds in the neighborhood of 530/500 MB/s. Modern motherboards use SATA III which maxes out at a throughput of 600MB/s (or 300MB/s for SATA II, in which case, it’s time to upgrade). NVMe M.2’s on the other hand, definitely do not, as we’re about to discuss.
SATA M.2 SSD drives and 2.5” SATA SSDs actually operate at virtually identical spec. M.2 drives can come in SATA versions (like the Crucial MX500 M.2 for example) and NVMe versions (like the Samsung 970 Pro/EVO), which describes the bus they use to electrically communicate with the other PC components. With both form factors, the component is connecting electrically to the PC via PCIe rather than SATA. It is also unrelated to the form factor, which is why NVMe drives can come in both M.2 or PCIe card form factors. Put another way, it’s a description of the bus the component uses to communicate with the PC, not a new type of flash memory. Essentially, it allows flash memory to operate as an SSD directly through the PCIe interface rather than going through SATA and being limited by the slower SATA speeds. Standing for “Non-Volatile Memory Express,” NVMe is an open standard developed to allow modern SSDs to operate at the read/write speeds their flash memory is capable of. So fast in fact, their limiting factor is not their own hardware, but rather the SATA III connection that hard drives have traditionally used. What is NVMe? The Samsung 960 Pro is was fastest NVMe drive on the market…until the 970 Pro replaced it….and the 980 Pro replaced that.įirst, a quick note about SSDs – they’re fast. But what about NVMe SSDs, how do they differ from standard SATA drives? And do all M.2 drives classify as NVMe? Read on while we break down the differences between NVMe vs. Not only are boot and shut down speeds much faster with SSDs, but all aspects of the system are sped up as well. And with data transfer speeds many multiples of traditional 7200 RPM and even 10,000 RPM drives, it’s easy to see why. One of the bigger breakthroughs for PC hardware in modern memory has been the solid state drive.
