WD Blue SN550 - Review 2022

Launched as a follow-upwards to terminal year's WD Blue SN500, the WD Bluish SN550 (starts at $54.99 for 250GB; $99.99 for our 1TB test model) is a respectably quick, highly affordable Thousand.two NVMe SSD that challenges other drives up to twice its cost in performance and speed. The bulldoze is a leader in its price class, every bit both a solid workhorse that tin can handle daily content-creation tasks in programs similar Adobe's primal creative applications, while as well holding its own in gaming tests and raw sequential throughput. This DRAM-less SSD (more than on that afterward) may non be the right pick for anyone who needs tons of write-durability, relative to other drives, just for the rest of us, it's a solid choice for the price. (Notation: At this writing, the 1TB version was selling from most etailers for twenty per centum above its MSRP.)

An Evolution of the Blue

WD Blue is Western Digital'southward more than value-oriented, mainstream SSD family, in contrast to the more than functioning-oriented, hardcore WD Black series. Still, it's no slouch on the specifications front.

The WD Blue SN550 is an M.2 Blazon-2280 PCI Express three.0 x4 NVMe SSD, based on a second-generation, 96-layer 3D TLC NAND manufacturing process. (Bank check out our SSD dejargonizer if you lot demand help unraveling that ball of acronyms.) This 80mm-long drive comes in three storage-volume sizes: 250GB, 500GB, and 1TB. Western Digital rates the 1TB variant of the bulldoze (the ane we're testing here) for peak throughput of 2,400MBps on sequential reads and 1,950MBps on writes, and it carries a five-year warranty. Hither's a summary of the bachelor capacities.

I of the main upgrades from the older SN500 model that we tested final year is the increment in PCI Express lane allotment, which straight affects peak throughput. The WD Blue has gone from ii lanes (PCI Express x2) in the previous model, a decidedly budget motion, to 4 (PCI Limited x4) in the SN550. That helps boost the top sequential read and write speeds from the SN500's one,700MBps and one,450MBps, respectively, to the SN550's numbers cited above.

The higher lane resource allotment puts the SN550 on par with virtually other mainstream M.2 drives nowadays. I place I'd like to see a fleck more muscle, though, is in the terabytes written (TBW) rating. For case, the Editors' Pick-winning Addlink S70 almost exactly doubles the TBW rating of the WD Blue SN550, while costing only roughly a 3rd more. This doesn't mean the WD Blue SN550 is a poor value, per se, but that it may not be the right selection for write-happy users, such as content creators who scribe lots of gigabytes of data per 24-hour interval to their drives.

DRAM? Where Nosotros're Going, We Don't Need DRAM

As I alluded to in the introduction, the WD Blue SN550, like many other cheap SSDs, is a DRAM-less drive. For starters, let's define what DRAM is in an SSD context and what it's used for.

In a traditional SSD with DRAM, the information that you're keeping is stored on the NAND wink chips that sit on the drive's printed circuit lath (PCB). The data isn't static, though, and is constantly being moved around past the drive to ensure that no cells are being taxed much more than than others and therefore habiliment down unevenly. This is a process called "wear leveling."

Because the data is moved effectually ofttimes, some SSDs use a smidge of DRAM—which is much faster to access and read than NAND flash—to "map out" the data, and provide a reference point for the bulldoze so it knows where everything is.

Now, a drive can operate just fine without a DRAM fleck installed. Instead, the "map" is stored either on the NAND flash fries themselves, or can be stored temporarily in the RAM of the organisation you're booting into. From the SSD maker'due south point of view, leaving off the DRAM saves on product cost, thereby making the drive cheaper to industry, and cheaper for consumers in the stop. Nonetheless, this can take a marked effect on drives that are used to store operating systems, programs, or games, all of which use shallow-depth 4K writes and reads.

WD seems to have gotten around this hurdle with the addition of a much smaller SRAM fleck ("static" RAM to DRAM'due south "dynamic" RAM). SRAM chips are faster than DRAM, though they can exist more than expensive to implement. WD also found a workaround for this, including merely a few megabytes of SRAM on the in-house Western Digital controller, rather than the larger SRAM caches that you might run across on other drives that implement a like technique.

With that bit of background out of the way, let's get into the benchmarks to see how this DRAM-less SSD handles...

Testing the WD Bluish: A Criterion Duel

We test all of our PCI Express 3.0 SSDs on an Asus Prime X299 Deluxe motherboard with an Intel Cadre i9-10980XE processor clocked at a max boost frequency of 4.6GHz. We use 16GB of DDR4 Corsair Dominator RAM clocked to 3,600MHz, and the system is using an Nvidia GeForce RTX 2080 Ti Founders Edition as its discrete graphics card.

PCMark 10 Overall Storage Test

First, there'due south the overall PCMark 10 Total Organization Drive Benchmark. This score represents how well drives exercise throughout the entire PCMark ten run, and are the sanctioned scores presented by UL's software at the end of each run. This score includes a weighted average of every faux activity that the PCMark 10 storage test runs, from copying files to launching games, booting an OS to running artistic applications. Information technology's a general indicator of how consistently a bulldoze can perform through 23 dissimilar usage scenarios.

Overall, the WD Blue SN550 was well ahead of its cost-comparative competition, showing that its added lanes and high 4K random read speeds make information technology a bully choice for all-around users.

Booting Windows ten

Adjacent is a more than granular measure derived from one of PCMark 10's background "traces." This and following PCMark 10-derived tests represent a simulation of how chop-chop a drive is capable of launching a detail program or booting Windows 10 by recording how many megabytes per second the bulldoze is reading what are known as "shallow-queue 4K random" blocks of information (i.eastward., of the kind in which virtually applications, games, or operating systems are stored). While UL recommends using the overall "read/write MBps bandwidth" metric in these tests, instead we dug a bit deeper to only include random 4K bandwidth in social club to paint what nosotros believe is a more specific pic of how well a bulldoze can perform in these tasks.

The first test is the Windows ten kicking trace, which simulates a full operating system startup procedure and records how speedily the drive is able to feed the information required for that task.

In this test the WD Bluish SN550 holds its ain against pricier drives like the Patriot P300, while likewise keeping pace with performers like the Seagate and TeamGroup.

Launching Games

Next up is a game-launching set, which simulates how apace a drive can read shallow-depth small random 4K byte packages. This is i of the more usually used file sizes for game installations, though that limerick does depend on the title you're playing.

While the 3 games tested in PCMark 10 are primarily stored in pocket-size random 4K, tests from around the web have shown that MMORPGs can more often use the 16K file size, and other genres may go as large as anywhere from 32K upwardly to 128K. However for the sake of these tests, 4K small random read is the most accurate metric to measure out the launch speeds of 3 popular FPS titles: Battlefield 5, Overwatch, and Call of Duty: Black Ops iv.

In these traces, the WD Blue SN550 regularly scores in the pinnacle tiers of its competitors when launching games like Overwatch or COD, though it lagged slightly behind more gaming-oriented drives like the Seagate FireCuda 510 and TeamGroup T-Force Cardea Ii in Battleground 5.

Launching Creative Applications

Here the drives are put through a very of import test for creative types. As anyone who regularly works in programs similar Adobe Premiere or Photoshop can tell you, frequently the nigh excruciating role of the whole experience is the time it takes for the program to launch. At that place are a lot of elements that creative applications need to load.

However, information technology should be noted, that these 2 tests don't tell the whole story of how a bulldoze volition perform for all creative applications. For example, cinema rendering programs like Cinema 4D may need to load dozens of dissimilar types of files at once, rather than just one large file like yous might have encased in a Photoshop project or a movie that's beingness edited in Premiere.

Depending on the complexity of your work and the number of elements in a scene, your software may have to load 3D models, sound files, physics elements, and more. The overall PCMark ten score of a drive volition tell a amend story for how a drive congenital to handle these types of programs will do than these numbers alone. Simply they're nonetheless interesting fodder for folks who live and breathe these Adobe apps.

Most of the drives we tested scored fairly even here, to the signal where you only might discover a difference between the WD Bluish SN550 and the Cardea 2 in applications like Adobe Premiere Pro with a stopwatch.

Copy Tests

Finally come the copy tests. While at first these numbers might await depression compared to the straight sequential-throughput numbers achieved in benchmarks like Crystal DiskMark 6.0 and AS-SSD, that's due to the way this score is calculated.

Unlike those tests, which re-create a file from another drive onto the testing bulldoze and record the raw writing throughput to the drive (or reading chapters off of it to another drive), PCMark 10 is expressing the average bandwidth speed of a transfer when the file is on the same drive. If you're regularly moving files around on your drive from one folder to some other, this examination is a handy relative throughput measure.

Right out of the gate, the WD Blue SN550 proves itself equally a very fast option (aslope the ADATA Spectrix S40G) if you're regularly shifting around programs or ISO files of the kind in these PCMark 10 traces. JPEG copying was considerably slower, but all the same competitive for its cost.

Crystal DiskMark 6.0

Okay, off of PCMark ten and onto a more traditional measure. The Crystal DiskMark six.0 sequential tests simulate best-case, straight-line transfers of large files. Let's go into the drag races.

Here the bulldoze finally starts to falter confronting some other drives we tested, but it actually exceeds (by a smidge) its WD-rated speeds in sequential reads and writes.

In dissimilarity, the utility's 4K (or "random read/write") tests simulate typical processes involved in plan/game launching...

Hither the drive is stiff in 4K random write speeds, and competitive in random read.

AS-SSD Copy Tests

Last up is a series of file and folder transfers done in the SSD benchmarking utility AS-SSD. This trio of tests involves copying large files or folders from one location on the test drive to another…

Though it's a bit difficult to put them up against 1 another 1:1 (the nature of the copied data is different in each case), the scores in the AS-SSD copy tests reiterate much of the same story nosotros saw in the PCMark 10 run: the WD Blue holds its own.

When Information technology'south Adept to Be Kinda Blueish

While the sequential results of the WD Blueish SN550 may not expect tip-top on the surface, it seems WD was more concerned with existent-world performance in the development of this drive, rather than just superlative scores in spec sheets.

Sure, it'southward e'er nice to see bigger numbers for any specification you publish, but what does that actually hateful for the people who buy and use the product? In this spirit, the WD Blue SN550 is a bit of a wolf in sheep's clothing once you factor in the price, the 4K read and write speeds, and its competitive operation across the board in the PCMark ten suite. Beyond the raw bandwidth numbers, it's clear that the WD Blue SN550 is a swell selection for all-around upkeep buyers who aren't overly concerned most write-immovability ratings.

As noted upwardly top, prices have spiked a chip, to $119, for the 1TB SN550 since the original $99 MSRP of the drive was minted (a tendency nosotros've seen across the component infinite over the past few months), just this isn't enough of a deviation to tank the value of the bulldoze outright. If y'all're looking for a solid SSD that can exercise virtually everything information technology promises at a respectable price bespeak, the WD Bluish SN550 is worth a 2d and a third look.
