Recently the increasing popularity are NVMe drives. Unlike traditional SSDS, where the data is transmitted via SATA interface and a speed of 550 MB/s, it uses a high-speed PCI Express data bus, allowing to achieve indicators of 3940 MB/s. the Most popular steel NVMe drives form factor M. 2.
Sold similar drives for about four years, but until recently, cost quite a lot, but the amount was too small to compete with the traditional SSD. And only in 2018 appeared affordable solutions where one of the most successful was the range of devices from Western Digital. In 2019, the company has updated its product WD Black PC SN750, increasing the maximum amount by updating the firmware, optionally with solutions of the radiator and added mode Game Mode, further increasing performance. We had the opportunity to test the new car, than of course we took advantage.
WD Black PC SN750 sold in four versions: 250 GB, 500 GB, 1 TB and 2 TB, has a claimed read speed 3470 MB/s and write 3000 MB/s. We got the WD Black PC SN750 (WDS100T3X0C) with capacity of 1 TB and is equipped with a radiator. In “Game mode”, the drive disables power-saving function and it does not go into sleep mode, which reduces latency at the primary accesses to the data. It is no secret that heating drives, like any other device with its own processor, subject to the throttle. To remove it, WD uses aluminum radiators from the well-known Slovenian manufacturer EK Water Blocks. This feature is optional, as in laptops simply will not find a place for it, and some motherboard manufacturers cards and so supply connectors M. 2 cooling systems.
To activate “Gaming mode” will require a proprietary tool Western Digital SSD Dashboard. I wonder why the manufacturer did not include this option by default. In addition, the program allows you to measure the temperature and speed of data access to determine the free space and service life, to do S. M. A. R. T. check and upgrade firmware, and delete data without possibility of recovery. Windows works with the drive via a standard driver.
Analyzing the obtained results, it can be noted that when using “Game mode”, the access time to the disk is significantly decreased, but the speed that has the lowest impact. Unlike synthetic, in real scenarios, when the drive OS is installed, you can still get a slight increase in speed by reducing access time, but hope for some big effect not worth it. But since energy consumption in Gamу mode is not greatly increased, then, if you are using a stationary PC is recommended always to enable it on laptops, he “cost” you the maximum in a couple of minutes of autonomy.
When compared to the previous generation, the speed performance of the drive has not changed: to increase only by changing the software part was impossible. However, Western Digital has development potential through the use of a 96-layer flash memory. “Game mode” turned out to be more of a marketing decision, not strongly influence the performance, but the use of the radiator really viable technical solution.
WD Black PC SN750 is still a good high-performance solution that extended to 2019 range due to models 2 TB. Last but not least, the company did not set on their top solution high price: a drive, 1 TB will cost about 12 500 rubles, or 13 000 rubles for the version with the radiator. WD Black PC SN750 is one of the best solutions on the market NVMe drives in terms of price and speed characteristics, which will be a great choice for high-performance modern builds.
