Requires improved controllers for stability

QLC: Quad Layer Cells, featuring 4 Bit flash – Highest Capacity available at the lowest price, but lower durability overall.

TLC: Triple-level cells (3-bit) NAND flash is low at 300-1000 write cycles, and can achieve 1500-3000 write cycles with 3D NAND.

eMLC (enterprise MLC) sustains up to10,000 write cycles, and can reach 35,000 cycles on 3D NAND

MLC: The 2-bit data multi-level cell (MLC) flash generally takes up to 3,000 write cycles.

SLC: Single-level cell NAND flash supports 50,000 to 100,000 write cycles.

NAND Types (the Cells/Chips used in the SSD) – Below are the key factors that you should keep an eye on when looking at the specifications and build of an SSD.

Often the higher the capacity of an SSD, the lower the durability (unless you go towards exceptionally high-end NAND), or the fact that the most expensive SSD does not always guarantee the highest IOPs, or negate the lower drive writes per day. It is with these that you can measure the suitability of the SSD with your own personal/business needs. Choosing the Right Samsung SSD – A Guide to the Terminologyīefore we discuss each of the Samsung SSD family members, it is worth highlighting some of the most common buying factors that affect the performance and durability of an SSD. Currently when it comes to buying a new SSD for your laptop, desktop PC, home console or portable screen device, they have a drive for practically every need and if you can work out the naming convention and naming strategy (which is a little more elusive than the popular WD colours method admittedly) it is surprisingly easy to choose the right Solid State Drive you need, first time! So, below I have covered the main product families, their advantages, disadvantages and what they are best suited for. In the SSD market, they have had more consistent success with their Pro, Evo and Plus range (spanning several subcategories) than Western Digital and Seagate combined. One of the earliest providers of flash technology for the consumer and commercial level, they have existed either overtly in the market, or in the background of most technology in one shape or form for decades. Of all the SSD brands in the home and business sector, there are not many brands that have had the meteoric impact on the memory and SSD market that Samsung has. 9.2 Related Understanding the Samsung Range of SSDs – Pro, Plus, Evo
