The budget-end WD Blue 3D NAND SSD WDS100T2B0A was released in 2017 as an economical solution to PC/Mac speed solutions. The SSD has lived up to its expectations and some suggest it is the best SSD currently available. Let’s look at the best features of the WD Blue SSD before doing a WD Blue SSD vs Samsung 860 Evo comparison later on in the article.

Who is it for?

The WD Blue SSD is a good option for just about everyone but if you’re a PC enthusiast or a creative pro and work with graphics and other similar stuff, then this is the ideal SSD for you in the budget SSDs category.

Interface and Form Factor

The WD Blue comes with a SATA 3 interface. It has a 2.5 inch or a 7mm form factor. It also has an M.2 2280 form factor, which makes it ideal to be used in PCs and laptops. However, for ultra-slim devices, the M.2 2280 wouldn’t fit.

Samsung 860 Evo SSD

The Samsung 860 Evo SSD came in 2018 and comes with great data encryption options from Samsung. This SSD is chosen the most by people seeking to purchase SSDs at economical prices. Let’s look at its best features.

Who is it for?

The Samsung 860 Evo SSD is perfect if you’re looking for an SSD for gaming purposes. This SSD is also quite good when it comes to professional computing like 4K video rendering or 3D rendering.

Interface and Form Factor

The SSD comes in a 2.5 inch or 7mm size. It also comes with M.2 2280 form factor that makes it suitable for usage in laptops or PCs. Samsung also offers the mSATA option for those seeking to install this SSD in ultra-thin devices. Its interface is SATA 3.

Differences – WD Blue SSD vs Samsung 860 Evo

Having specified each and every detail about the two drives, it now comes to finding the differences. In the above specifications, there are no differences at all, and the WD Blue SSD being the cheaper option seems just about the right choice. But, there’s a catch to it.

The Samsung SSDs have been lasting longer than WD Blue SSDs, and that makes them a good option when it comes to durable SSDs. Another key difference comes in the TBW rates. The Samsung 860 Evo has far better TBW rates that make it ideal for rendering and gaming purposes. Here is a table of the TBW rates that come with both SSDs.

Size Samsung 860 Evo WD Blue 3D SSD
250GB 150TBW 100TBW
500GB 300TBW 200TBW
1TB 600TBW 400TBW
2TB 1200TBW 500TBW
4TB 2400TBW 600TBW

Final Verdict – Which One to Buy?

If you’re just looking for a smaller-sized SSD with non-professional or casual computer work, then go for the cheaper option. However, if you want an option that lasts longer and has faster TBW rates, then go for the bit more expensive Samsung one.

For heavy gaming or professional usage, the Samsung 860 Evo is recommended by us, but it is priced a little higher. In short, both SSDs are solid budget options and perform very well. It depends on you and your laptop/PC/Mac usage on which one suits you best.
