To those that doubt the veracity of our assertion that BiCS 4 performs better than Micron B47R or Samsung V-NAND, we can and have demonstrated this on multiple occasions. Whenever everything is equivalent except the flash (same controller, same DRAM), good ole 96 Layer BiCS 4 arrayed SSDs easily outperform 176 Layer B47R arrayed SSDs. A good example is the M10P vs. S70 Blade or FX900 Pro. B47R is more prolific but has never outperformed BiCS, period - end of story. Half the layers, older and still the better performer; that's just how superior BiCS architecture has proven to be. And we don't even need to get into how much better BiCS 4 is than V-NAND because even B47R arrayed SSDs easily outperform Samsung's V-NAND arrayed 980 Pro. A range of capacities from 1TB to 4TB means you get to keep more of today’s games that can take up 200GB or more of storage. WD also implemented new updates to improve thermal consistency and energy efficiency via smoothing out the thermal throttling step function. WD Management Dashboard A new suite of features comes with the SN850X including Predictive Loading, Overhead Balancing and Adaptive Thermal Management 5. The 1TB and 2TB drives have an optional version with RGB lighting plus heatsink to help maintain peak performance through the most intense gaming sessions. (Please choose the heatsink model for this)

When it comes to benchmarking storage devices, application testing is best, and synthetic testing comes in second place. While not a perfect representation of actual workloads, synthetic tests do help to baseline storage devices with a repeatability factor that makes it easy to do apples-to-apples comparison between competing solutions. These workloads offer a range of different testing profiles ranging from “four corners” tests, common database transfer size tests, to trace captures from different VDI environments. The latest version of Game Mode serves up even more PC performance-boosting features like load prediction to ready game assets for fast in-game loading. In our SQL Server application test aimed at developers or homelab users, the SN850X showed a solid 3ms in latency, placing it near the top of the leaderboard of the other tested drives. While it wasn’t leaps and bounds better than its predecessor (the SN850), it did show noticeable improvements over a drive that is still considered a great-performance drive at almost 2 years old.All of these tests leverage the common vdBench workload generator, with a scripting engine to automate and capture results over a large compute testing cluster. This allows us to repeat the same workloads across a wide range of storage devices, including flash arrays and individual storage devices. Our testing process for these benchmarks fills the entire drive surface with data, then partitions a drive section equal to 1% of the drive capacity to simulate how the drive might respond to application workloads. This is different than full entropy tests which use 100% of the drive and take them into a steady state. As a result, these figures will reflect higher-sustained write speeds. Insane speeds up to 7,300 MB/s deliver top-tier performance with ridiculously short load times for the elite gaming experience you’ve been waiting for. Um novo conjunto de recursos vem com o SN850X, incluindo Predictive Loading, Overhead Balancing e Adaptive Thermal Management 5. Insane speeds up to 7,300 MB/s 1 deliver top-tier performance with ridiculously short load times for the elite gaming experience you’ve been waiting for. Velocidades insanas de até 7.300 MB/s 1 fornecem desempenho de alto nível com tempos de carga ridiculamente curtos para a experiência de jogadas de elite que você tem esperado.

This is a fairly noticeable increase compared to the 2020 SN850 model’s 7GB/s read and 5.3GB/s write in sequential and 1 million IOPS in 4K random performance. The SN850 also only offers up to 2TB in capacity, so the 4TB model is a nice addition to match the ever-growing game installation sizes. Today’s A-list titles can take up 200GB 2 or more of storage. A range of capacities from 1TB to 4TB 2 means you get to keep more games at the ready and get into the action fast.The SN850's Gaming Mode worked by disabling lower power states, ensuring the drive would be more responsive. Game Mode 2.0 works differently with a three-pronged approach: predictive loading, adaptive thermal management, and overhead balancing. Predictive loading is an algorithm designed to detect upcoming low queue depth, sequential workloads - particularly the read workloads prevalent in many games. Adaptive thermal management works to improve average and sustained throughput via smoother throttling. Finally, overhead balancing seeks to improve read latency while gaming through I/O prioritization. The 1TB model is quoted with slightly lower numbers in sequential writes with 6.3GB/s, while random reads are a bit lower as well with 800,000 IOPS. The endurance rating is 600 TBW (total bytes written) for the 1TB, 1,200 TBW (2TB) and 2,400 TBW (4TB) with an MTTF rating of 1.75 million hours.

This test uses SQL Server 2014 running on Windows Server 2012 R2 guest VMs and is stressed by Quest’s Benchmark Factory for Databases. StorageReview’s Microsoft SQL Server OLTP testing protocol employs the current draft of the Transaction Processing Performance Council’s Benchmark C (TPC-C), an online transaction-processing benchmark that simulates the activities found in complex application environments.Game Mode 2.0 also features an advanced “read look ahead” algorithm, which predicts and pre-emptively caches what is next in the game. WD indicates that this is done by allowing the SN850X’s controller to detect incoming low queue depth, sequential workloads, claiming that it will help speed up in-game loading of scenes, levels and other areas. UL's newest 3DMark SSD Gaming Test is the most comprehensive SSD gaming test ever devised. We consider it superior to testing against games themselves because, as a trace, it is much more consistent than variations that will occur between runs on the actual game itself. This test is in fact the same as running the actual game, just without the inconsistencies inherent to application testing.
