If you are planning to upgrade your laptop/desktop HDD to SSD then this is for you.
NVMe (Non-Volatile Memory Express) is an interface protocol built specifically for Solid State Drives (SSDs). Before NVMe, SATA and SAS are used with SSDs in computers until recently.
NVMe was built from scratch to efficiently access storage devices that are specifically built with flash memory – SSDs. NVMe enables a faster interface to leverage the speeds that SSDs are capable of. Since SSD used to replace HDD in recent computers as primary storage, a new interface was needed to make use of SSD’s faster speed capability. However, in the transition to SSD, some laptops have been outfitted with Solid State Drive where it was previously running with older SATA HDD. It is more effective to use NVMe with an SSD.
The seek time for data is ten times faster when it comes to speed. NVMe can provide sustained read-write speed of 2000MB/s, way faster than the SATA SSD III, which limits at 600MB/s. Because of NAND technology utilized on NVMe, which is rapidly advancing, which shows that we’ll see higher speeds soon with NVMe.
Take, for example, the 1 TB Samsung 860 Pro SSD has a maximum read speed of 560MB/s. whereas, the NVMe-based 960 Pro is more than six times faster than 860 Pro, with a top speed of 3,500 MB/s.
If you’re much concerned about your system performance and data speed we’d put NVMe as priority solution. It has longevity, performance and speed when compared to SATA SSD.
