1TB SSD Western Digital witnesses the infinite possibilities of high functional SSD

With the release of E16 main control chip at the Taipei exhibition by Phison Eletronics Corporation, many storage manufacturers have also released their own PCIe 4.0 SSD. The speed experience brought by bandwidth expansion is really good. But compared with upgrade, the premium price does not seem significant for ordinary consumers.

In addition, what are other possibilities of high performance SSD? We may get the answer from the Western Digital WD_BLACK SN750 NVMe SSD with radiator version.

Evaluating WD_BLACK SN750 NVMe SSD with radiator version.
WD_BLACK SN750 NVMe SSD with radiator which includes three capacities 500 GB, 1TB and 2TB and standard version are launched in this early year. Today we evaluate 1TB SSD to know about its performance.

SanDisk 64–layer 3D NAND flash with SanDisk controller

I believe that PC hardware players understand the definition of bottom logo, which also indicates the great accomplishment of WD_BLACK SN750 NVMe SSD with radiator in heat dissipation. Its collaboration with EKWB, the leader in PC cooling, will bring temperature control to its current extreme and break through storage boundaries in order to provide the most top-level game experience for game enthusiasts.

Evaluation of WD_BLACK SN750 SSD

After six screws are unscrewed, the SSD can be dismantled. We can see that there are silicone heat dissipation gaskets under its mental bottom.

WD_BLACK SN750 NVMe SSD with radiator and standard version apply to SanDisk 64-layer 3D NAND flash, whose storage density is twice of the last generation. Therefore, the maximum capacity of WD_BLACK SN750 NVMe SSD is 2TB.

It is unilateral PCB design with two SanDisk 512GB 3D NAND flash in PCB sides respectively and external cache of Hynix DDR4. WD_BLACK SN750 NVMe SSD with radiator also uses SanDisk 20-82-00700-A1 controller made in Taiwan, China.

It is reported that the SanDisk controller has an optimized architect for BiCS flash memory. It mainly optimized the client workload including PC games and high-performance business applications. The three–core architecture of 28nm technology relies more on hardware accelerator to execute NVMe command processing and transmit date from flash to host. And it implements layered cache to improve performance like nCache3.0, which has multi-layer error correction function. These operations was handled by professional hardware and don't affect main control function.

The speed of reading and writing are both 3000MB/s
Examination of consecutive reading and writing
First, we evaluate the continued reading and writing speed of CrystalDiskMark from WD SSD. The software reads and writes speed test tends to be uncompressed algorithm, but the non-compression algorithm SSD has the characteristics of no speed drop. The CrystalDiskMark version is 6.1.0 x64, the default queue depth is 1, and the default number of tests is 5. Let's see the test results.

The largest consecutive reading speed is 3491.4MB/S and writing speed is 3011MB/S in the CrystalDiskMark evaluation. Continued the excellent performance of the standard version, such results can be said to be quite good, of course, as the main high-end game experience of the SSD should also reach this level.

The performance is still good and also manifests the stable strength of this product in TxBENCH examination.

The reading and writing performance of WD_BLACK SN750 NVMe SSD with radiator still maintain its strength in ATTO evaluation. The speed of reading and writing is respectively 3480MB/S and 3033MB/S, the stable performance is enough to see its excellent performance in daily real-life use scenarios.

4K Random Reading and Writing Test
4K performance decides to the products actual experience in complicated daily life. We usually apply AS SSD Benchmak to exam products' actual performance.

The largest 4K random reading and writing are respectively 436K and 560K of this WD_BLACK SN750 NVMe SSD with radiator. The total score is 5684. This performance is still the stable first echelon performance in the peer PCIe 3.0 x 4 SSD, which means that it can bring us real performance improvement in daily use.

Cache capacity testing
We use 20GB data to exam the SSD capacity. Through the performance, we find that the WD SSD begin to decelerate in 13GB. So, the capacity is about 13GB.

PC MARK8 comprehensive text
Lastly, we text WD_BLACK SN750 NVMe SSD of Western Digital comprehensively through PC MARK8.
As an old PC testing tool, PC MARK8 built-in storage performance test can accurately reflect the actual performance of storage products under simulated daily loads.

We find that the total score of WD_BLACK SN750 NVMe SSD of Western Digital in PC MARK8 examination is 5067, while the concrete broadband speed is 476.15MB/S which is still the level of the first echelon. Therefore, the WD_BLACK SN750 NVMe SSD is really excellent.

Support game model
After installing WD_BLACK SN750 NVMe SSD of Western Digital with radiator, we can download the dedicated dashboard on the official website for real-time monitoring of hard disk performance and start its exclusive game mode.

After opening game model, 4K random reading performance has been improved in  a certain extent. The gap of game experience mainly exists in top games. The game screen of Lonely Spirit 5 and Tomb Raider: Rise is 2K resolution and full-effect. The game load time has about a second to increase the speed, you may think that only a second, which is almost the same, but in fact, the game mode will shut down the low power on the solid-state hard disk at work. So that your solid-state hard disk in your game to maintain high-performance mode and firepower at any time, anywhere, which is to optimize our entire game experience. Therefore, the test performance advantage will not be obvious.

Summary
Western Digital has shocked us a lot in recent two years. This WD_BLACK SN750 NVMe SSD with radiator has still maintained the best performance of standard version.  it is a necessary factor of superior product that the write and read speed reach 3000MB/S or 4K random read and write speed attach 560K.

Of course, as a special SSD for games, its greatest highlight should be the professional game mode. A good product should have internal and external advantage, which should has not flagship hardware configuration but supporting software that can achieve more functions.
