WD Blue SN550 PCIe NVMe SSD has great value and performance
4.8Overall Score
Name: WD Blue SN550 PCIe NVMe SSD 250/500GB abd 1TB
Price (RRP): $about 22 cents per GB
Manufacturer: WD

The WD Blue SN550 at 22 cents per gigabyte, is all that most value-conscious PC/laptop owners could want.

The WD Blue SN550 is aimed at the replacement market offering more than four times the speed of a SATA 6 SSD/HDD and yet a price point about 30% less than the top speed SSDs like the WD Black.

And the question is, do you need the speed of the WD Black anyway? The answer is that unless you are doing a disk-intensive task like video/still rendering of large files, then you are not going to use the WD Blue SN550 top-end speed anyway.

What is it?

It is a PCIe 3.0 x 4 lane NVMe 1.4, M.2, 2280 format SSD for PCs and laptops. Speed tops out around 2400/2000Mbps sequential read/write and has quite respectable large file random read/write speeds.

It is TLC (Triple Layer Cell/3-bit) with some of that allocated to SLC (single-level cell/1-bit) cache. WD does not disclose cache size but our tests show it fills at about 15GB or 1.5% of the drive. That is pretty good.

 It also implements the latest NVMe 1.4 protocol that accounts for part of the drive’s performance.

GadgetGuy’s take – The WD Blue SN550 is impressive for the price

Dare we call it the value champ? Well, it is certainly up there in performance and storage for the price.

It is not the fastest, but it is well above the slowest.
