Solid state drive technology is becoming increasingly advanced, allowing for cheaper and faster drives to be developed.
This cost saving carries down to the consumer, with cheaper entry-level SSDs shipping to market each year along with faster high-end drives.
The quality and capabilities of an SSD are measured by a number of specifications, including read/write speed, capacity, and mean time before failure (MTBF).
MTBF is especially important for determining the endurance and projected lifetime of a solid state drive, and it is also important to note both the random and sequential read/write speeds.
SSDs appear in multiple form factors, from 2.5-inch SATA drives to RAM-like M.2 modules. The interface the drive uses determines its maximum transfer speed, with SATA being the slowest and PCIe generally the fastest.

Some drives, such as Intel’s Optane add-in-card SSDs, are used for specific purposes such as caching for high-demand enterprise environments, while others, such as the WD Blue SSD range, offer attractively-priced drives to everyday consumers.
To help you decide which is the best for you, we have listed some of the best SSDs you can buy in 2019.
