What makes this product the writers choice?

This TLC NAND drive delivers blistering sustained write speeds that come close to the performance of MLC NANDs. It also offers stunning value when you look at the price per gigabyte.

TLC NAND (Tripple Level Cell)

Storing 3 bits per cell, TLC flash is the cheapest form of flash to manufacture. The biggest disadvantage of this type of flash is that it is only suitable for consumer usage, and would not be able to meet the standards for industrial use.

Read/write life cycles are considerably shorter at 3,000 to 5,000 cycles per cell.


  • Cheapest to manufacture which in turn leads to cheaper to market SSDs.


  • Cells will survive considerably less read/write cycles compared to MLC NAND. This means that TLC flash is good for consumer use only.

Recommended for:

  • Everyday consumer use, web/email machines, netbooks, and tablets.

MLC NAND (Multi Level Cell)

MLC flash as its name suggests stores multiple bits of data on one cell. The big advantage of this is the lower cost of manufacturing versus manufacturing SLC flash.

The lower cost in flash production is generally passed onto you as the consumer, and for that reason is very popular among many brands. MLC flash is preferred for consumer SSDs for it’s lower costs but the data read/write life is less in comparison to SLC at around 10,000 per cell.


  • Lower production costs are passed onto you the consumer.
  • Is more reliable than TLC flash.


  • Not as durable and reliable as SLC or enterprise SSDs.

Recommended for:

  • Everyday consumer use, gamers, and enthusiasts.

The above comparison gives a valid reason as to why MLC are preferred over TLC but one biggest disadvantage lies in the price of the MLC which is comparatively higher costing about $700 for 512 GB product. As WD Blue 3D delivers performance close to that of an MLC at a much lower price, it is the most preferred product.
