Comparison Products for WD Bluish SN550 1TB
Today, nosotros pit the WD Blueish SN550 up against a variety of worthy competitors as well equally a few alternatives to better reveal value. From WD, we threw in the Black SN750, the company's high-end NVMe SSD, and a 6TB WD Black 7200RPM HDD. From Crucial, we've included the P1, a QLC based NVMe SSD and the MX500, a very popular SATA SSD. Likewise, we dropped in the Kingston A2000, Intel SSD 665p, and Team Grouping's MP33 every bit alternative value options. Finally, we added in one of our favorite SSDs, the Adata XPG SX8200 Pro, and one of the fastest SSDs PCIe 4.0 SSDs bachelor, the Corsair Force MP600. Let's have a look at where the WD Blue SN550 lands in this diverse grouping of drives.
Game Scene Loading - Final Fantasy XIV
The Last Fantasy Fourteen StormBlood and Stormbringer are 2 complimentary real-world game benchmarks that easily and accurately compare game load times without the inaccuracy of using a stopwatch.
WD'southward Blue SN550 ranks well overall here, scoring 3rd and fourth place in the Stormblood and Shadowbringer benchmarks, respectively. It also manages to outperform the more-expensive WD Black SN750 advertising well as the Corsair Force MP600. Information technology'southward also more than twice as fast as the HDD at loading the game files.
Transfer Rates – DiskBench
We use the DiskBench storage benchmarking tool to test file transfer operation with our own custom blocks of data. Our 50GB data set includes 31,227 files of various types, like pictures, PDFs, and videos. Our 100GB includes 22,579 files with 50GB of them existence large movies. We copy the data sets to new folders and then follow-up with a reading exam of a newly written half-dozen.5GB zilch file, 8GB test file, and a 15GB movie file.
If y'all oft deal with massive file transfers, clearly WD'southward Black SN750 or Corsair'south Strength MP600 are the fashion to go with their more robust controllers. However, WD's Blue SN550 will provide acceptable operation for almost.
Its copy performance aligns with most of the alternative value options and ranks the drive at fifth place in those tests. In reading back data, the WD Blue ranks in 4th place with a clear advantage over the other value competitors. Its read performance is impressively almost as fast as the Adata XPG SX8200 Pro.
Trace Testing – PCMark ten Storage Tests
PCMark 10 is a trace-based criterion that uses a broad-ranging ready of real-globe traces from popular applications and mutual tasks to measure the performance of storage devices. The quick criterion is more relatable to those who use their PCs lightly, while the full benchmark relates more to ability users. If you are using the device as a secondary drive, the data examination will be of near relevance.
Scoring 3rd place in both the data and quick benchmarks, the WD Blue SN550 excels, providing responsive performance. Crucial's P1 delivered very similar performance with higher bandwidth, although with just a hair more latency.
Surprisingly, the WD Blue fifty-fifty outperforms the Black SN750 once more in all of PCMark 10's storage benchmarks. Under the full criterion, the Intel SSD 665p and Kingston A2000 have 2nd and third identify, bumping down the WD Blue to fourth. But overall there isn't all that much difference in functioning between the three in PCMark10's well-nigh demanding workload test.
Trace Testing – SPECworkstation 3
Like PCMark 8, SPECworkstation iii is a trace-based benchmark, but it is designed to push the organization harder by measuring workstation functioning in professional applications.
With less idle fourth dimension to recover and a lot more than reading and writing going on, SPECworkstation 3's benchmark is a low-stop SSD killer. But while WD's Blueish SN550 is a low-cost SSD, it provides virtually the aforementioned performance every bit WD's Blackness SN750, despite its express bandwidth. Overall, information technology ranks in fourth identify and should provide enough of performance for those looking to use the bulldoze in their new workstation just as much as a new gaming build.
Synthetics - ATTO
ATTO is a uncomplicated and free application that SSD vendors commonly apply to assign sequential performance specifications to their products. It also gives us insight into how the device handles unlike file sizes.
In ATTO, we tested WD's Blue SN550 at a QD of i, representing most day to twenty-four hour period file access at various block sizes. The WD Blue'south sequential performance peaked at two.two/1.9 GBps read/write, which is about ix times faster than what the WD Blackness HDD tin do. And at smaller file sizes information technology shows a distinct advantage over the WD Black SN750, hence the faster application performance in PCMark10'due south workloads.
Synthetic Testing - iometer
iometer is an advanced and highly configurable storage benchmarking tool that vendors oft use to measure the performance of their devices.
Peak sequential operation hits two.four/2.0 GBps read/write, scoring the WD Blueish SN550 fourth and fifth identify, respectfully. WD's Bluish SN550 is more responsive to random requests than the WD Black SN750. Random 4K latency is also pretty low, peculiarly on the writes.
Meridian random operation isn't as skilful, withal. Since the controller is tuned for efficiency, its somewhat limited bandwidth allows the Bluish to however hit upwards of 235,000/377,000 IOPS read/write, which is astronomically more than capable than an HDD.
Sustained Write Performance, Enshroud Recovery, and Temperature
Official write specifications are only function of the functioning moving picture. Most SSD makers implement a write cache, which is a fast area of (commonly) pseudo-SLC programmed flash that absorbs incoming data. Sustained write speeds tin endure tremendously once the workload spills outside of the enshroud and into the "native" TLC or QLC flash. We utilise iometer to hammer the SSD with sequential writes for 15 minutes to measure both the size of the write cache and functioning later the cache is saturated. We also monitor enshroud recovery via multiple idle rounds.
When possible, we also log the temperature of the drive via the S.One thousand.A.R.T. data to run into when (or if) thermal throttling kicks in and how it impacts operation. Bear in mind that results volition vary based on the workload and ambience air temperature.
The WD Blue SN550's write performance is extremely consistent compared to many SSDs, thanks to its static SLC cache, rather than the dynamic cache of most higher-priced drives these days. Fifty-fifty when the write cache is exhausted and without DRAM to assist FTL direction, the WD manages to deliver faster performance than even higher-end SSDs. Information technology wrote 12GB of data at a rate of two GBps then degraded to an average write speed of 880 MBps for the remainder of the test. Its write cache recovers apace also. Within 30 seconds of idle fourth dimension, it is set up for more writes.
When information technology comes to estrus, the WD Blue SN550 does a pretty good job at keeping cool with static air (no airflow) within our 25 degrees Celsius testing environment. WD specifies that the SSD will throttle performance if information technology surpasses the rated operating temperature of seventy degrees Celsius.
When moving a few hundred gigabytes of information around, to and from the drive, pinnacle temps reported in at merely over lxx degrees Celsius. Nevertheless, manually measuring with our infrared thermometer, we saw both the NAND parcel and controller barely hitting 61 degrees Celsius and the drive didn't showroom whatever thermal throttling at the time.
Power Consumption
We apply the Quarch HD Programmable Power Module to gain a deeper understanding of power characteristics. Idle power consumption is a very important attribute to consider, especially if you're looking for a new bulldoze for your laptop. Some SSDs can consume watts of ability at idle while better-suited ones sip just milliwatts. Average workload ability consumption and max consumption are 2 other aspects of power consumption, merely performance-per-watt is more important. A bulldoze might consume more than ability during any given workload, but accomplishing a chore faster allows the bulldoze to drop into an idle state faster, which ultimately saves power.
WD's Blue SN550 scores loftier in our efficiency test. With a score of 220 MBps per watt used, it scores third place overall. Its average consumption is low and its maximum ability consumption figures are well regulated too. The company rates the bulldoze to hitting an ultra-low power state where it consumes simply 5mW, and then it should be a expert fit for mobile use.
However, idle power consumption on our desktop system leaves some room for improvement. About every other SSD we've tested recently switches into lower idle power states on our examination platforms, while the WD consumes a bit more than power than average.
