After a protracted construct up, Microsoft’s much-awaited DirectStorage technology has lastly arrived on PCs, promising blink-and-you’ll-miss-it loading instances—and our early take a look at ends in Forspoken, the primary DirectStorage sport, say it might lastly be time to begin waving bye bye to SATA SSDs.
What is Microsoft DirectStorage?
DirectStorage’s most touted function is transferring the job of decompressing sport belongings (corresponding to textures and fashions) from the CPU to the GPU. This frees up CPU assets and significantly hastens the method through the use of the large parallel engines accessible in right now’s GPUs, enabling ultra-fast load instances and asset streaming…assuming your system features a obligatory NVMe SSD, that’s. Here’s a deeper look at DirectStorage if you happen to’re .

Crucial
To learn how efficient DirectStorage is right now, we sat down with an MSI Infinite RS desktop system outfitted with an Intel Core i9-13900KF CPU, MSI GeForce RTX 4090 GPU, and 32GB of Adata DDR5/5200 in an MSI Z790 Pro motherboard working Windows 11 22H2.
Although the GPU can (and can) have an effect on DirectStorage efficiency, I actually don’t suppose players are going to alter their GPU for the know-how so right now’s testing is laser-focused on storage implications.
How we examined
The MSI Infinite RS desktop got here geared up with a PCIe 4.0 NVME 2TB MSI M480 Spatium SSD constructed round a Phison PS5018-E18 controller. The machine additionally got here with a secondary 2TB WD Blue 7,200 RPM exhausting drive.
For our assessments, I additionally included a 2TB SK Hynix P41 NVMe PCIe 4.0 drive, a 1TB XPG Atom 50 NVMe PCIe 4.0 drive, an older 512GB Samsung PM951 NVMe PCIe 3.0 SSD, and a now-discontinued Intel Optane 800P NVMe PCIe 3.0 drive as properly. To spherical out our testing, I additionally included a 1TB Samsung 860 EVO and a 2TB Samsung 870 QVO drive, each working on a slower SATA connection slightly than NVMe. Microsoft constructed DirectStorage particularly for NVMe drives.
Most storage opinions use the favored CrystalDiskMark 8, so let’s begin there for a take a look at common efficiency of those SSDs. I’ll solely present the learn efficiency of the drives since that’s what principally issues in DirectStorage—how briskly you’ll be able to switch sport belongings to the GPU.
Here’s the outcomes of the examined drives utilizing CrystalDiskMark 8 benchmark.
IDG
As you’ll be able to see, utilizing the default CrystalDiskMark configuration, the MSI M480 and SK Hynix P41 prime the charts in sequential switch speeds (utilizing a queue depth of eight and a single thread). Among the entire outcomes the benchmark spits out, that is the one typically quoted in advertising and marketing supplies and by shoppers. I wish to level out the XPG Atom 50’s oddball efficiency. The drive is definitely a budget “host memory buffer” model. Rather than integrating a DRAM cache on the SSD itself, like regular, it depends on the PC’s system reminiscence for the duty as an alternative.
Microsoft DirectStorage benchmarks
So how does the efficiency of a drive in CrystalDiskMark translate to the courageous new world of DirectStorage? To discover out, we used the unique DirectStorage 1.1 demo launched by Microsoft final yr. The demo primarily duties the GPU with decompressing a number of gigabytes of fashions and textures on the GPU, then spits out a number of outcomes such because the bandwidth and time used.
We report the time it takes to load the scene in addition to what the demo reviews in bandwidth. The outcomes level to a big bandwidth benefit on the Gen 4 drives. Interestingly, the finances XPG Atom 50 utilizing host-based DRAM truly has a slight edge—however all three of the Gen 4 drives we checked out have been shut sufficient it in all probability didn’t matter.
The older Samsung PM951 will get punished in bandwidth, as does the Optane drive. The actual unhealthy information is the entire SATA gadgets find yourself lifeless even, no matter whether or not working NAND or spinning platters, so its the drive interface that’s possible the bottleneck right here. Again: Microsoft requires an NVMe SSD for DirectStorage to work correctly.
Microsoft’s DirectStorage demo favors the quick M.2 NVMe Gen 4 drives however interstingly says that previous exhausting drive ain’t that unhealthy.
IDG
In precise load instances, nevertheless, it’s all possible nearer than you anticipate within the DirectStorage 1.1 demo. All three Gen 4 drives prepared the ground in loading and decompressing the belongings in beneath a second. That aged PM951 Gen 3 drive isn’t so unhealthy although, clocking in at 2 seconds. The final NVMe drive, the Intel 800P, loses handily to the entire different M.2 drives. That possible signifies the one factor Optane was actually good at—serving up small information at low and life like queue depths—gained’t matter as a lot in a DirectStorage world. So goodbye Optane, you have been in all probability proper to give up once you did.
Microsoft’s DirectStorage demo, nevertheless, is only a instrument made by the corporate for builders to get their toes moist. How do the identical drives fare when confronted with a benchmark from an precise launched sport? For that we used the first-ever DirectStorage sport, Square Enix’s Forspoken.
Forspoken’s built-in benchmark hundreds sport belongings for seven totally different scenes and reviews how lengthy it took to load, in addition to the body charge. Again, we’re centered solely on how DirectStorage impacts storage efficiency, so we ignored the body charge, however we used the identical sport settings throughout the entire runs.
The Gen 4 drives completely scream via loading the totally different scenes, though the Atom 50 barely lags within the first. It’s not a giant deal although. We ought to word that whereas our outcomes are a mean of a number of runs, the ends in the Forspoken benchmark exhibited a bigger than anticipated quantity of variability at instances, particularly with slower gadgets.
IDG
As you’ll be able to see, the traditional Samsung PM951 Gen 3 SSD can also’t sustain with the newer Gen 4 drives—however in a lot of the scenes, it’s nonetheless actually quick.
We can’t say that concerning the exhausting drive. The DirectStorage demo says it ain’t that unhealthy, however Forspoken says in any other case. In reality, the exhausting drive is unsurprisingly horrible. There’s a cause most players switched to SSDs way back.
But the actual query is how a lot of a bump you get going from a SATA SSD to a NVMe M.2 SSD in a DirectStorage sport. Well, SATA drives are considerably slower. For instance, in scene 3, the Samsung 860 Evo takes 7.4 seconds to load the scene vs the 1.9 seconds on the Spatium SSD. Across the entire scenes, the MSI M480 Spatium NVMe drive cuts the load instances by 77 p.c.
The upshot is SATA SSDs, which till now have principally carried out no totally different than NVMe SSDs in video games, are solely going to lose floor as sport builders and {hardware} distributors proceed to optimize for NVMe SSDs and DirectStorage, which is now a part of Windows.
Is that SATA SSD executed right now? No. In reality, DirectStorage can have little or no influence on the overwhelming majority of present video games individuals play, but it surely’s clear that the solar is lastly beginning to set on SATA SSDs.
