It's been a while since we've heard from Patriot on the SSD front, but they are back with a new and powerful DRAMless offering.

Introduction & Drive Details

Lately, we've been getting a wave of DRAMless SSDs arriving at the lab doorstep. Until just recently, we've looked down on DRAMless SSDs because they've historically sucked, but our attitude toward them has done a total 180 with the introduction of powerful Gen4 DRAMless SSDs. This new generation of DRAMless SSDs so far are fire, even capable of outperforming many full-on 7,400 MB/s capable Gen4 Hyper-Class SSDs. We never thought we would see the day, but it is upon us. After all, who could foresee little power-sipping 2.5-watt 4-channel DRAMless SSDs beating up on a whole host of power-hungry, fire-breathing 8-channel Hyper-Class SSDs? We sure didn't.

With a new outlook on DRAMless SSDs, we were excited to see Patriot's Gen4 DRAMless P400 hit retail channels. Hey, maybe this is another good one? A quick call to Patriot, and we had one arrive at the lab in no time. We weren't sure how the P400 would be configured. Still, we did suspect it would be another collaborative effort with InnoGrit seeing as how the Patriot's last significant SSD, the Viper VP4300 came forth from a collaborative effort with the upstart controller company.

Our suspicion turned out to be spot-on as Patriot's newest offering is indeed powered by an InnoGrit controller in front of a Micron flash array. In fact, it's the very same combo that first changed our attitude toward DRAMless SSDs. Patriot's P400 series is powered by InnoGrit's potent DRAMless IG5220 4-channel controller and arrayed with Micron 176 Layer B47R Fortis grade flash. Well, now, this should be good, so let's get this thing on the bench and see what it can do for you.

Everything looks on-point as far as stated performance capabilities and endurance are concerned, BUT those prices are way off the mark for what this SSD is. Not sure why the 1TB model would retail for $210, but something has to be off with that price point - it's $30 more than a 1TB VP4300 is selling for. Hopefully, Patriot will get that adjusted soon; they will have to if they plan on selling any P400's.

CrystalDiskMark verifies Patriots stated "up to "sequential specs for the P400. These numbers also verify that the P400 is controlled by an InnoGrit IG5220 controller. A 4K Q1T1 random read speed of 101 MB/s confirms the drive is indeed arrayed with Micron Fortis grade B47R flash. Excellent.

Read performance is always performance that matters, and here we get our first taste of the P400 punching above its weight, so to speak. As our chart shows, the P400 is outperforming a whole host of 7,000 MB/s capable SSDs. This becomes even more impressive when we consider just how much of the score here comes directly from sequential speeds, where the 7,000 MB/s capable SSDs have a huge advantage.

Sequential performance at 128K is traditionally where InnoGrit controlled SSDs tend to struggle a bit, and the P400 is no exception. Even the best performing flash-based SSD we've ever tested, another InnoGrit controlled SSD, the Plextor M10P, gets low marks at sequential 128K transfers.

The P400 impresses here by quickly digesting 100GB of a crushing mix of data composed of more than 62K files. The P400 slots in directly above the SN770, which is our current performance champion for all SSDs available in the Americas. Mind-blowing for a DRAMless 4-channel SSD.

Patriot's P400 1TB delivers the second-best read transfer rate ever for a 4-channel SSD, let alone a DRAMless SSD. Excellent.

3DMark SSD Gaming Test

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.

In short, we believe that this is the world's best way to test an SSDs gaming prowess and accurately compare it against competing SSDs. The 3DMark SSD Gaming Test measures and scores the following:

  • Loading Battlefield V from launch to the main menu.
  • Loading Call of Duty Black Ops 4 from launch to the main menu.
  • Loading Overwatch from launch to the main menu.
  • Recording a 1080p gameplay video at 60 FPS with OBS (Open Broadcaster Software) while playing Overwatch.
  • Installing The Outer Worlds from the Epic Games Launcher.
  • Saving game progress in The Outer Worlds.
  • Copying the Steam folder for Counter-Strike Global Offensive from an external SSD to the system drive.

Gaming is a performance metric that matters to the majority of DIY consumers, especially to the enthusiast crowd that TweakTown caters to. We would like to see better results here for sure but totally expected for its hardware configuration. The P400 does prove to be equivalent or slightly better for gaming than Samsung's legendary 970 Pro for whatever that's worth.

PCM10 Storage Tests

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.

The Full System Drive Benchmark and the Quick System Drive Benchmark. The Full System Drive Benchmark writes 204 GB of data over the duration of the test. The Quick System Drive Benchmark writes 23 GB of data over the duration of the test. These tests directly correlate with mainstream user experience.

PCMark 10 Full System Drive Benchmark

This particular test writes 204GB data and covers a broad range of common consumer tasks, including booting Windows 10, file transfers, Adobe and Office applications, and startup times for games including Battlefield V, COD Black Ops 4, and Overwatch. Unlike synthetic numbers, this is comprehensive real-world data which is why we use it to rank SSDs in terms of user experience.

When we step back and take a broad overall view of this chart, and the 7,000 MB/s capable SSDs the P400 is beating, this result becomes more impressive than our chart represents at first glance. A DRAMless SSD that handles heavy consumer workloads is always impressive as we see it.

Again, if we dissect this result a bit, the P400 becomes a bit more impressive. We note this 4-channel DRAMless SSD is charting right in there with many 7,400 MB/s capable Hyper-Class SSDs, including Seagate's FireCuda 530.

Final Thoughts

Patriot's P400 is the third of the new generation PCIe Gen4 DRAMless SSDs we've tested to date. This drive, like the other two, delivers compelling performance that redefines the realm of DRAMless SSDs. DRAMless SSDs are not just for laptops anymore. They can, in many cases, perform as well or even better than full-blown eight-channel drives with onboard DRAM.

We rank SSDs in terms of overall user experience (performance where it matters most) as expressed by PCMark 10 storage and 3DMark gaming storage tests. We consider a user experience score of 11K or more to verify an SSD as a TweakTown Elite performer. Already having experience with this hardware configuration, we knew ahead of time that the P400 wouldn't have enough gas in the tank to become a member of the TweakTown Elite. Gaming performance holds back this hardware combo from becoming such. Nevertheless, a user experience ranking of 9,800 is nothing short of amazing for what this SSD is and better than many 7,000 MB/s capable SSDs.

In terms of consumer workload performance and endurance, the P400 is a top-notch consideration for the majority of DIY consumers; however, its current price point is concerning. We believe that Patriot will indeed bring its pricing for the P400 in-line with similarly configured competing SSDs. Because we think this will happen sooner rather than later, we will award the P400 our silver award based purely on its performance alone.
