Okay, off of PCMark 10 and onto a more traditional measure. The Crystal DiskMark 6.0 sequential tests simulate best-case, straight-line transfers of large files. Let's get into the drag races.Because the data is moved around frequently, 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 drive so it knows where everything is. Here the drive is strong in 4K random write speeds, and competitive in random read. AS-SSD Copy Tests Right out of the gate, the WD Blue SN550 proves itself as a very fast option (alongside 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 still competitive for its cost. Crystal DiskMark 6.0 In this test the WD Blue SN550 holds its own against pricier drives like the Patriot P300, while also keeping pace with performers like the Seagate and TeamGroup.

As used for storage capacity, 1GB = 1 billion bytes and 1TB = one trillion bytes. Actual user capacity may be less, depending on operating environment. A WD Blue SATA Internal SSD can last up to 1.75M hours MTTF 2 (mean time to failure), with up to 600 TBW 3 (terabytes written), and has built in technology to correct errors in real time. Based on read speed, unless otherwise specified. As used for transfer rate, megabyte per second (MB/s) = one million bytes per second. Performance will vary depending on your hardware and software components and configurations.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 10 score of a drive will tell a better story for how a drive built to handle these types of programs will do than these numbers alone. But they're nonetheless interesting fodder for folks who live and breathe these Adobe apps. Here the drive finally starts to falter against some other drives we tested, but it actually exceeds (by a smidge) its WD-rated speeds in sequential reads and writes. Finally come the copy tests. While at first these numbers might look low 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. TBW (terabytes written) values calculated using JEDEC client workload (JESD219) and vary by product capacity. WD seems to have gotten around this hurdle with the addition of a much smaller SRAM chip ("static" RAM to DRAM's "dynamic" RAM). SRAM chips are faster than DRAM, though they can be more expensive to implement. WD also found a workaround for this, including just a few megabytes of SRAM on the in-house Western Digital controller, rather than the larger SRAM caches that you might see on other drives that implement a similar technique.

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 it a great choice for all-around users. Booting Windows 10 While the sequential results of the WD Blue SN550 may not look tip-top on the surface, it seems WD was more concerned with real-world performance in the development of this drive, rather than just peak scores in spec sheets. Unlike those tests, which copy a file from another drive onto the testing drive and record the raw writing throughput to the drive (or reading capacity 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 another, this test is a handy relative throughput measure. In contrast, the utility's 4K (or "random read/write") tests simulate typical processes involved in program/game launching...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 data that you're keeping is stored on the NAND flash chips that sit on the drive's printed circuit board (PCB). The data isn't static, though, and is constantly being moved around by the drive to ensure that no cells are being taxed much more than others and therefore wear down unevenly. This is a process called "wear leveling." The ultra-compact M.2 2280 WD Blue SATA SSD Drive goes through extensive compatibility and reliability testing to ensure it meets the high standards of the WD brand. 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… In these traces, the WD Blue SN550 regularly scores in the top 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 Battlefield 5.
