The SN850X is specced with PCIe Gen4 performance, quoting up to 7.3GB/s read and 6.6GB/s write in sequential transfer speeds for the 2TB and 4TB model. In random 4K performance, the higher-capacity models are expected to reach up to 1.2 million IOPS read and 1.2 million IOPS write.

Of particular note is the Game Mode 2.0 feature that's new with the SN850X. The original Gaming Mode could be turned on or off within the Dashboard, but Game Mode 2.0 has an additional Auto setting to detect game launches. You can also manually enter game folder locations so the software knows where to watch. The SN850X had weak random write performance, though it did display an improvement over its predecessor with a peak of 187K IOPS at a latency of 678.7µs (vs. 173K IOPS and 733.9µs for the SN850). 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. 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.

Each SQL Server VM is configured with two vDisks: 100GB volume for boot and a 500GB volume for the database and log files. From a system resource perspective, we configured each VM with 16 vCPUs, 64GB of DRAM and leveraged the LSI Logic SAS SCSI controller. While our Sysbench workloads tested previously saturated the platform in both storage I/O and capacity, the SQL test is looking for latency performance. Recording a 1080p gameplay video at 60 FPS with OBS (Open Broadcaster Software) while playing Overwatch. Nonetheless, the SN850X is an impressive drive that stands tall among the already vast selection of mainstream consumer SSDs. Adding the RGB lighting and heat sink option to the drive makes it stand out even further, adding a bit of gaming flair to PC rigs with glass cases. 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. DirectStorage sure sounds as that there will be some improvement, albeit assuming you aren't running GPU at full load already, as DirectStorage apparently works mainly at the premise of taking some workload from the CPU and giving it to the GPU, such as to decompress files that get loaded in when walking to a new area in an open-world game. And for current-gen gaming, even slower NVMe SSDs sure are plenty fast.

While SSD tuning software such as this often doesn’t show any noticeable real-world gains, it does allow users to perform firmware upgrades via the application (among other things), which is more functionality than many other companies provide. You can also see (at a glance) the drive’s overall health, interface speed, temperatures and capacity information. Overall the software is nice to have but won’t deliver “felt” performance to the end user. Warranty and Pricing 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. 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. 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. 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.

PCMark 10 Storage Test is the most advanced and most accurate real-world consumer storage test ever made. There are four different tests you can choose from; we run two of them. Extremely low latency loads graphics fast with minimal stutter and lagging for an incredibly smooth, satisfying gaming experience. Game Mode 2.0 serves up even more PC performance-boosting features like load prediction to ready game assets for fast in-game loading.

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.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.

A new suite of features comes with the SN850X including Predictive Loading, Overhead Balancing and Adaptive Thermal Management 5. 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.
