WD Blue SN570 Review: An Affordable Entry-Level PCIe 3.0 NVMe SSD

The WD Blue SN570 NVMe SSD, first announced on October 4, brings both the price and performance of NVMe SSDs to a new low.

Indeed, the new drive’s performance reminds me of the Crucial P1 — it’s more of a sprinter than a marathoner. On top of that, without the support for PCIe 4.0, the new SSD is not supposed to be an upgrade to the older WD Blue SN550.

But that a friendly cost of just $49.99, $59.99, and $109.99 for the 250GB, 500G, and 1TB capacities, respectively, it’s one of the most affordable NVMe SSD you can find. You can expect the street price to be even lower over time.

And even though the WD Blue SN570 doesn’t have much to brag about in performance among its NVMe peers, it’s still faster than most, if not all, SATA SSDs, let alone regular hard drives.

If you have a computer with an NVMe slot — most do these days — and want a replacement internal storage device, the SN570 is a good fit. Get one!

Dong’s note: I first published this post as a news piece on October 4, 2021, and last updated it on October 20 as an in-depth review after extensive hands-on testing.

WD Blue SN570: An affordable (and slow) alternative

Out of the box, the SN570 shares the blue color as the SN550. The new SSD has a standard form factor and is, therefore, has the same shape as all single-sided NVMe drives. It’ll work in any application where a 2280 drive is needed.

No PCIe 4.0, standard endurance

As the latest NVMe drive, the WD Blue SN570 disappointingly doesn’t support the new PCIe 4.0 standard, just PCIe 3.0 instead. It’ll work with the former, just at slower speeds.

Considering this is a modest drive in terms of performance — more in the performance section below — the PCIe 4.0 omission might be a good thing. It helps keep the cost down.

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

Indeed, the new drive has a rating of some 0.3 DWPD (drive written per day) and a five-year warranty. That means you can write up to a third of the drive’s total capacity per day and every day for five years.

If you want to put that in the total amount of data, it has the rating of 150TBW, 300TBW, and 600TBW for the 250GB, 500GB, and 1TB, respectively. And those are the same as the PCIe 4.0 counterparts, including the Crucial P5 or the Samsung 980 PRO.

Considering WD calls the Blue as an SSD “built with creators in mind, providing fast speeds, data protection, and endurance to support their creative vision,” though, I was hoping that its endurance would be better.

But again, for the cost, the new SSD still has a lot of value.

Hardware specifications: WD Blue SN570 vs WD Blue SN550

Western Digital is tight-lipped about the actual specs of its WD Blue SSDs. Instead, it only provides general information and what kind of performance and endurance you can expect from them.

Excellent Dashboard software, no features

The WD Blue SN570 comes with a downloadable Dashboard software that enables users to monitor the drive’s performance, life expectancy, upgrade its firmware, and more.

The software is intuitive and easy to use, akin to the Samsung Magician counterpart. Unfortunately, the drive itself has almost no user-accessible features.

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

Specifically, the new SSD has no over-provisioning or hardware encryption. There’s no way to turn up its performance via software either. In all, the Blue SN570 is a frill-free storage device.

WD Blue SN570: Modest (write) performance

Again, the WD Blue SN570 reminded me of the Crucial P1 in performance. It has a short bust of high-speed performance but, in extended tasks, proved to be the slowest NVMe SSD I’ve seen.

WD Blue SN570 NVMe SSD Copy Write Test
WD Blue SN570 NVMe SSD write speed fluctuated and plateaued at consistently slow speeds after some 15GB. The screenshots here show the write-only (top) and read/write combo tests using Windows File Explorer.

It’s worth noting, though, that this modest performance is only in the drive’s write speed. Its read speed is generally on par with other NVMe SSDs.

Specifically, in copy (sequential) tests, the drive can handle around 15GB of data with NVMe-grade speed — it’s fast. After that, it slows down to around 500MB/s — about the speed of a regular SATA SSD — and remains that way until the rest of the job.

WD Blue SN570 Copy Performance
The WD Blue SN570 did well in reading tests, but its write speed suffers in a task that involves larger than 15GB of data.

On the chart above, note that the Read or Write tests use 10GB data, while the Combined test used 27GB. That’s the reason why the latter was much slower.

The “sprinter” effect was more acute in random access where the drive needs to perform both read and write constantly. Here, the WD Blue SN570 proved to be the slowest NVMe SSD I’ve seen in heavy tasks.

WD Blue SN570 Random Access Performance Chart
WD Blue SN570’s write performance was the worse among NVMe SSDs in heavy random access tasks.

In a lighter random access test, it did better, however.

I also used the WD Blue SN570 in daily tasks for anecdotal testing, and the real-world experience was generally similar to other drives.

However, when I needed to copy a lot of data or use resource-intensive applications, such as Photoshop, to consolidate an extensive database, it was clear that this SSD wasn’t the ideal choice.

Conclusion

In many ways, the WD Blue SN570 represents an affordable NVMe SSD option. If you’re looking to upgrade an entry-level computer for daily tasks, it’s a great buy.

But if you want something that can deliver the best performance, get another NVMe option instead. For intensive tasks, even the WD Blue SN550 is better.
