WD Blue SN570 Evaluate: Sluggish however Reasonably priced

WD Blue SN570 Review: Slow but Affordable

The WD Blue SN570 NVMe SSD, first introduced on October 4, brings each the worth and efficiency of NVMe SSDs to a brand new low.

Certainly, the brand new drive’s efficiency jogs my memory of the Essential P1 — it’s extra of a sprinter than a marathoner. On prime of that, with out the help for PCIe 4.0, the brand new SSD shouldn’t be presupposed to be an improve to the older WD Blue SN550.

However {that a} pleasant value of simply $49.99, $59.99, and $109.99 for the 250GB, 500G, and 1TB capacities, respectively, it’s one of the crucial reasonably priced NVMe SSD yow will discover. You may anticipate the road worth to be even decrease over time.

And regardless that the WD Blue SN570 doesn’t have a lot to brag about in efficiency amongst its NVMe friends, it’s nonetheless sooner than most, if not all, SATA SSDs, not to mention common exhausting drives.

When you have a pc with an NVMe slot — most do as of late — and desire a substitute inside storage machine, the SN570 is an efficient match. Get one!

Dong’s be aware: I first revealed this put up as a information piece on October 4, 2021, and final up to date it on October 20 as an in-depth evaluate after in depth hands-on testing.

The WD Blue SN570 is a single-sided commonplace NVMe SSD.

Quick (learn) efficiency for informal computing

Wonderful Dashboard software program


Low random entry efficiency and gradual write copy pace in prolonged duties

No safety or user-accessible overprovisioning options

Capacities cap at simply 1TB

WD Blue SN570: An reasonably priced (and gradual) various

Out of the field, the SN570 shares the blue coloration because the SN550. The brand new SSD has a normal kind issue and is, due to this fact, has the identical form as all single-sided NVMe drives. It’ll work in any software the place a 2280 drive is required.

No PCIe 4.0, commonplace endurance

As the newest NVMe drive, the WD Blue SN570 disappointingly doesn’t help the brand new PCIe 4.0 commonplace, simply PCIe 3.0 as a substitute. It’ll work with the previous, simply at slower speeds.

Contemplating this can be a modest drive by way of efficiency — extra within the efficiency part under — the PCIe 4.0 omission may be factor. It helps maintain the fee down.

The SN570 shares one factor with most new PCIe 4.0-based SSDs, nevertheless: Endurance.

Certainly, the brand new drive has a ranking of some 0.3 DWPD (drive written per day) and a five-year guarantee. Meaning you’ll be able to write as much as a 3rd of the drive’s complete capability per day and daily for 5 years.

If you wish to put that within the complete quantity of information, it has the ranking of 150TBW, 300TBW, and 600TBW for the 250GB, 500GB, and 1TB, respectively. And people are the identical because the PCIe 4.0 counterparts, together with the Essential P5 or the Samsung 980 PRO.

Contemplating WD calls the Blue as an SSD “constructed with creators in thoughts, offering quick speeds, information safety, and endurance to help their artistic imaginative and prescient,” although, I hoped that its endurance could be higher.

However once more, for the fee, the brand new SSD nonetheless has lots of worth.

Western Digital is tight-lipped in regards to the precise specs of its WD Blue SSDs. As a substitute, it solely offers common info and how much efficiency and endurance you’ll be able to anticipate from them.

Wonderful Dashboard software program, no options

The WD Blue SN570 comes with a downloadable Dashboard software program that permits customers to observe the drive’s efficiency, life expectancy, improve its firmware, and extra.

The software program is intuitive and simple to make use of, akin to the Samsung Magician counterpart. Sadly, the drive itself has nearly no user-accessible options.

The Dashboard of the WD Blue SN570 NVMe SSD
The Dashboard of the WD Blue SN570 NVMe SSD is well-designed.

Particularly, the brand new SSD has no over-provisioning or {hardware} encryption. There’s no solution to flip up its efficiency through software program both. In all, the Blue SN570 is a frill-free storage machine.

WD Blue SN570: Modest (write) efficiency

Once more, the WD Blue SN570 jogged my memory of the Essential P1 in efficiency. It has a brief bust of high-speed efficiency however, in prolonged duties, proved to be the slowest NVMe SSD I’ve seen.

WD Blue SN570 NVMe SSD Copy Write Test
WD Blue SN570 NVMe SSD write pace fluctuated and plateaued at constantly gradual speeds after some 15GB. The display reveals the write-only (prime) and browse/write combo checks utilizing Home windows File Explorer.

It’s value noting, although, that this modest efficiency is simply within the drive’s write pace. Its learn pace is mostly on par with different NVMe SSDs.

Particularly, in copy (sequential) checks, the drive can deal with round 15GB of information with NVMe-grade pace — it’s quick. After that, it slows right down to round 500MB/s — in regards to the pace of a daily SATA SSD — and stays that means till the remainder of the job.

WD Blue SN570 Copy Performance
The WD Blue SN570 did nicely in studying checks, however its write pace suffers in a process that includes bigger than 15GB of information.

On the chart above, be aware that the Learn or Write checks use 10GB information, whereas the Mixed take a look at used 27GB. That’s the explanation why the latter was a lot slower.

The “sprinter” impact was extra acute in random entry the place the drive must carry out each learn and write continually. Right here, the WD Blue SN570 proved to be the slowest NVMe SSD I’ve seen in heavy duties.

WD Blue SN570 Random Access Performance Chart
WD Blue SN570’s write efficiency was the more serious amongst NVMe SSDs in heavy random entry duties.

In a lighter random entry take a look at, it did higher, nevertheless.

I additionally used the WD Blue SN570 in every day duties for anecdotal testing, and the real-world expertise was typically just like different drives.

Nonetheless, once I wanted to repeat lots of information or use resource-intensive functions, equivalent to Photoshop, to consolidate an in depth database, it was clear that this SSD wasn’t the perfect selection.


In some ways, the WD Blue SN570 represents an reasonably priced NVMe SSD choice. Should you’re seeking to improve an entry-level laptop for every day duties, it’s an excellent purchase.

However if you need one thing that may ship one of the best efficiency, get one other NVMe choice as a substitute. For intensive duties, even the WD Blue SN550 is healthier.
