Review Terms and DisclosureĪll Information as of the Date of Publication The 2TB capacity and models with the heatsink will be available in February.
The Western Digital Black SN750 is shipping now in 250GB, 500GB, and 1TB capacities. We will continue to evaluate this drive over the coming weeks as the heatsink-equipped models hit the market and Western Digital's competitors launch their 2019 updates. Since we had relatively little time with SN750, this has been just an initial overview of its performance.

The BPX Pro is still a great value if you're willing to trade just a bit of random and sustained write performance. Since this drive is just hitting the market we don’t yet know how street prices will settle, but taking the MSRP into consideration the SN750 is right in line with its performance compared to Samsung. Like most SSDs, the value of the WD Black SN750 comes down to performance for the price. As for the WD Black SN750, it bests its predecessor and comes in at a respectable third place, also beating Samsung's well-reviewed EVO parts.Īgain, a test like this looks at a scenario that many users may never encounter, but it gives a good indication of the flexibility of a drive to perform well in many different use cases. Also of note is the Crucial P1, which as a budget drive has absolutely awful performance once you've exhausted its cache. Samsung's PRO-series advantage is evident in this test, as both the 960 and 970 PRO maintain very high write performance throughout the transfer. These speeds can fluctuate a bit up and down for the faster drives so we rounded the results to a fair average. We ignore the performance of the first 60 seconds of the transfer and then take the average write speed from 60 seconds on to the completion of the transfer. This is what a sustained write test seeks to determine once you've exhausted your drive's cache, how severe is the performance hit? To test this, we created a single 120GB file and copied it to each drive. The following charts contain sequential and random performance as indicated in each chart's title. We ran CrystalDiskMark 6.0.2 to evaluate the transfer rate (measured in megabytes per second) and IOPS as reported by the utility. We performed the following benchmarks with Gaming Mode both enabled and disabled on the SN750. A reboot is required whenever the mode is changed. For those interested in the feature, Gaming Mode is enabled or disabled via a toggle in the main interface of the latest version of the WD SSD Dashboard.

This is likely acceptable to desktop users with adequate component cooling but those looking to install the SN750 in their laptop may not want to take the hit to battery life.
The result, of course, is that energy usage and temperatures will be higher when Gaming Mode is enabled.

By keeping the drive in its full power mode at all times, gamers or professionals who seek the absolute best performance can avoid any hits to drive responsiveness. Since modern SSDs automatically and rapidly shift into low-power states as needed to improve energy efficiency and thermals, latency can be impacted when an event triggers the drive to return to full power. New with the SN750, however, is "Gaming Mode," which prevents the drive from entering a low-power state. For recent WD SSDs, the Dashboard provides information on capacities and wear life, temperature, interface speed, performance monitoring, and access to firmware updates and S.M.A.R.T.
Wd black diskmark update#
The Western Digital Black SN750 ships alongside an update to the company's SSD Dashboard software for Windows. The drives were tested in an open-air testbed. Our testbed's BIOS was configured to disable C-States and Windows was configured to operate in High Power mode. Prior to testing, each drive was filled to approximately 50 percent capacity with 478GB of assorted data containing movies, game installations, photos, and documents. Memory: 2x8GB Team Group T-Force Xcalibur RGB DDR4 2400MHzįor this initial testing, we sought to compare the WD Black SN750 to other 1TB-class drives.

Motherboard: ASUS ROG Maximus IX Code Z270 Western Digital Black SN750Īll drives referenced in the benchmarks were tested on the following platform: The drive will be available in additional capacities as detailed below.
We were supplied only with the 1TB model for this review, so we're focusing on evaluating how the 1TB SN750 compares to other drives in the same capacity class. Read on for our review of the WD Black SN750 NVMe SSD. We had a brief time to review the 1TB non-heatsink model and have some initial performance results to share.
