What is a solid state drive (SSD) and M.2 SSD?
A solid state drive (SSD) is newer storage technology, but it’s still been around for a while now, and if you have a modern laptop, it’s likely that it uses an SSD.
As the name suggests, an SSD – unlike a traditional hard drive – has no moving parts. Instead, it uses NAND flash memory. The more NAND (Negative-AND) memory chips an SSD has, the more storage capacity it has. Modern technology allows SSDs to have more NAND chips than ever, which means SSDs can have capacities similar to HDDs.
Many SSDs come with SATA III ports, which means they can be easily installed in place of a HDD, and many also come in the 2.5-inch format that smaller hard drives also come in. However, the maximum data throughput of SATA III is 600MB/s, and while this is fine for HDDs, SDDs are capable of much faster speeds, which means if you have an SSD with a SATA III connection, the drive’s performance is actually being held back by its SATA connection.
What is M.2?
The M.2 specification allows device makers to fit flash storage modules into thin and light devices, like today's razor-slim notebook PCs, that may struggle to accommodate a typical 2.5-inch SSD. But M.2 isn't exclusive to portable PCs.
M.2 SSDs are designed to enable high-performance storage in thin, power-constrained devices, such as ultrabook and tablet computers. They are generally smaller than mSATA SSDs, for which they are intended as an alternative.
The M.2 form-factor specification was defined by the PCI Special Interest Group (PCI-SIG) consortium of technology industry vendors and the Serial ATA International Organization. The M.2 specification supports applications such as Wi-Fi, Universal Serial Bus (USB), PCI Express (PCIe) and Serial ATA (SATA).
M.2 SSDs are faster and store more data than most mSATA cards. M.2 SSDs support PCIe 3.0, SATA 3.0 and USB 3.0 interfaces, while mSATA only supports SATA. M.2 SATA SSDs have similar performance to mSATA cards, but M.2 PCIe cards are faster. SATA SSDs have a maximum speed of 600 MB per second, while M.2 PCIe cards can hit 4 GB per second.
M.2 SSD optimizes performance for your daily computing tasks, boasting sequential write speeds up to 520 MB/s with TurboWrite technology and sequential read speeds up to 540 MB/s. Plus, RAPID mode to further boost performance for up to 2x faster** data processing speeds by utilizing unused PC memory as cache storage.
M.2 drive is same as a normal 2.5 inch drive but smaller in size and you can directly plug it into your motherboard. Thus, saving space. For example, Samsung 860 evo 250 GB 2.5 inch drive is as faster as Samsung 860 EVO 250 GB M.2 drive.
But when we talking about NVMe than it is actually many folds faster than normal 2.5inch drive and M.2 drive. Like Samsung 970 evo 250GB M.2 NVMe.
