After an extended construct up, Microsoft’s much-awaited DirectStorage know-how has lastly arrived on PCs, promising blink-and-you’ll-miss-it loading occasions—and our early check ends in Forspoken, the primary DirectStorage sport, say it could lastly be time to start out waving bye bye to SATA SSDs.
What’s Microsoft DirectStorage?
DirectStorage’s most touted function is transferring the job of decompressing sport belongings (comparable to textures and fashions) from the CPU to the GPU. This frees up CPU assets and enormously quickens the method by utilizing the large parallel engines accessible in immediately’s GPUs, enabling ultra-fast load occasions and asset streaming…assuming your system features a obligatory NVMe SSD, that’s. Right here’s a deeper have a look at DirectStorage when you’re .

Essential
To learn how efficient DirectStorage is immediately, 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 Professional motherboard operating Home windows 11 22H2.
Though the GPU can (and can) have an effect on DirectStorage efficiency, I actually don’t assume players are going to vary their GPU for the know-how so immediately’s testing is laser-focused on storage implications.
How we examined
The MSI Infinite RS desktop got here outfitted 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 checks, 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 nicely. To spherical out our testing, I additionally included a 1TB Samsung 860 EVO and a 2TB Samsung 870 QVO drive, each operating on a slower SATA connection relatively than NVMe. Microsoft constructed DirectStorage particularly for NVMe drives.
Most storage critiques use the favored CrystalDiskMark 8, so let’s begin there for a have a look at basic efficiency of those SSDs. I’ll solely present the learn efficiency of the drives since that’s what largely issues in DirectStorage—how briskly you possibly can switch sport belongings to the GPU.
Right here’s the outcomes of the examined drives utilizing CrystalDiskMark 8 benchmark.
IDG
As you possibly can 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). Amongst all the outcomes the benchmark spits out, that is the one typically quoted in advertising supplies and by shoppers. I need to level out the XPG Atom 50’s oddball efficiency. The drive is definitely a finances “host memory buffer” mannequin. Reasonably 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 search out out, we used the unique DirectStorage 1.1 demo launched by Microsoft final 12 months. The demo basically 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 document the time it takes to load the scene in addition to what the demo studies in bandwidth. The outcomes level to a enormous bandwidth benefit on the Gen 4 drives. Apparently, the finances XPG Atom 50 utilizing host-based DRAM really has a slight edge—however all three of the Gen 4 drives we checked out had 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 dangerous information is all the SATA units find yourself lifeless even, no matter whether or not operating NAND or spinning platters, so its the drive interface that’s seemingly the bottleneck right here. Once more: 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 dangerous.
IDG
In precise load occasions, nevertheless, it’s all seemingly nearer than you count on within the DirectStorage 1.1 demo. All three Gen 4 drives prepared the ground in loading and decompressing the belongings in below a second. That aged PM951 Gen 3 drive isn’t so dangerous although, clocking in at 2 seconds. The final NVMe drive, the Intel 800P, loses handily to all the different M.2 drives. That seemingly signifies the one factor Optane was actually good at—serving up small information at low and real looking queue depths—gained’t matter as a lot in a DirectStorage world. So goodbye Optane, you had been in all probability proper to stop whenever you did.
Microsoft’s DirectStorage demo, nevertheless, is only a software made by the corporate for builders to get their ft 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, Sq. Enix’s Forspoken.
Forspoken’s built-in benchmark hundreds sport belongings for seven completely different scenes and studies how lengthy it took to load, in addition to the body fee. Once more, we’re targeted solely on how DirectStorage impacts storage efficiency, so we ignored the body fee, however we used the identical sport settings throughout all the runs.
The Gen 4 drives completely scream via loading the completely different scenes, though the Atom 50 barely lags within the first. It’s not a giant deal although. We should always observe that whereas our outcomes are a median of a number of runs, the ends in the Forspoken benchmark exhibited a bigger than anticipated quantity of variability at occasions, particularly with slower units.
IDG
As you possibly can see, the traditional Samsung PM951 Gen 3 SSD can also’t sustain with the newer Gen 4 drives—however in many of the scenes, it’s nonetheless actually quick.
We are able to’t say that concerning the exhausting drive. The DirectStorage demo says it ain’t that dangerous, however Forspoken says in any other case. In reality, the exhausting drive is unsurprisingly horrible. There’s a purpose most players switched to SSDs way back.
However 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. Nicely, 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. Throughout all the scenes, the MSI M480 Spatium NVMe drive cuts the load occasions by 77 p.c.
The upshot is SATA SSDs, which till now have mainly carried out no completely 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 Home windows.
Is that SATA SSD performed immediately? No. In reality, DirectStorage can have little or no impression 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.
