What is the difference between SSD and NVMe?
Advantages of NVMe technology.
SSD (Solid State Drives)
It is a hardware device that uses "solid-state" storage technology through flash memory.
Unlike traditional storage using hard disk drives (HDD), SSDs have no moving parts, resulting in a much higher data transfer speed.
NVMe (Non-Volatile Memory Express)
Similar to SSDs, it is a type of flash storage that contains no moving parts, additionally implementing non-volatile memory, a memory that can store your data even after the power is turned off.
NVMe is much faster than traditional flash storage, allowing for more efficient data transfer between storage systems and servers.
In terms of speeds, they are up to six times faster than SATA-based SSDs and 10 times faster than hard disks, which is especially noticeable when reading and writing large files, thus being recommended for projects that include this type of data.
Considering that it is a relatively new technology, the purchase cost will be somewhat higher, but the performance offered will be justified by the processing speeds.
Notable differences between the two technologies are:
- NVMe storage provides non-volatile memory for data storage;
- Transfer speeds in the case of large files are incomparable to SSDs;
- Considerable increase in read and write operations that can be run simultaneously.
