AvoidConsiderShortlistBuyIntroduction & Drive Details
Sometimes an SSD comes along that has us scratching our heads. This is one of those SSDs. As far as we can tell, there are only two attributes that the FireCuda X1070 has to offer that might appeal to a small segment of the DIY gaming community. It is single-sided at 4TB, which we love, and it is very power-efficient, both of which are an absolute must for handhelds and laptops alike.
The drive is marketed as offering generous space for all your games and streams, which is indeed accurate; however, it is also marketed as high-capacity storage without the premium price tag, which is borderline laughable. The 4-channel, DRAMless, QLC arrayed, PCIe Gen4 interfaced FireCuda X1070 has all the attributes that have always signaled a bargain in storage good enough to overlook its inherently inferior performance - but not this time.
As we rifle through Amazon looking at the current and highly inflated selling prices of SSDs, one thing stands out to us: we can't find even one NVMe SSD coming from a normal seller that is priced as high as our test subject. You can even get a 4TB Samsung 9100 Pro for $50 less than the FireCuda X1070 4TB. We understand that flash is like gold these days, but come on, man, this is absurd at $830 for 4TB of some of the lowest performing NVMe storage we've ever encountered.

Please note: We employ an M.2 AIC for testing on our Intel Core Ultra 9 285K platform.
Sony PlayStation 5 - M.2 Storage Expansion
PS5 Read Performance
With Sony's wildly popular PlayStation 5 console now enabled for M.2 NVMe SSDs to be used as fast storage expansion, we are including results for PS5-compatible SSDs we test as a part of our reviews going forward.


For SSDs that don't have an adequately sized PS5 compatible heatsink or other SSDs where the heatsink provided doesn't fit right and can be removed, we both use and recommend Sabrent's unparalleled PS5 heatsink available HERE.


We only chart SSDs that can deliver a minimum of 5,500 MB/s read, which is Sony's original recommendation.

Its sequential read speed in a PS5 environment suggests the FireCuda X1070 4TB makes for a decent choice for PS5 M.2 storage expansion.
Synthetic Benchmarks: CDM, Max IOPS, ATTO
CrystalDiskMark





We employ CDM as our standard measurement for both sequential throughput and Q1T1 random read. In terms of sequential throughput, the FireCuda X1070 4TB delivers exactly as advertised. However, looking at the all-important Q1T1 random read speed, we must do a double-take as it's the lowest we can remember ever seeing coming from a drive in its class.
Max IOPS




Highest price for the lowest IOPS. Not looking too good.
ATTO




ATTO gives us a clear picture of what transfer sizes a particular SSD favors in terms of QD4 sequential throughput. We chart 128K transfers. At a queue depth of four, the X1070 4TB favors sequential transfers of 1MB or larger when serving data to the host (reading) and 256KB or larger when programming (writing) data.
Real-World Testing: Transfers, 3DMark SSD Gaming Test, PCM10 Storage
Transfer Rates



Our 100GB data transfer test is not your ordinary 100GB of data; ours is a crushing mix composed of more than 62K files. Writing performance, random or sequential, is an infrequent operation, and thus, we do not consider it to be an important performance metric in the consumer space. An example is how many times a game is installed vs. how many times it's played. Speeds here are again at the bottom of the barrel.



Unlike programming (writing) data, serving data to the host (reading) is typically an important performance metric as it relates to the consumer space. Speeds here are pleasantly surprising.
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 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 most DIY consumers, especially for the enthusiast crowd that TweakTown caters to. Now we've reached the point where results start to matter as they are a direct reflection of user experience.
The performance exhibited here is not what you want to see coming from a "Gaming SSD".
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. These tests directly correlate with mainstream user experience.
PCMark 10 Full System Drive Benchmark
This test writes 204GB of 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 such as 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.



Even though the performance delivered here is again near the bottom of our chart, it is an acceptable result for an SSD that is priced right, which this SSD certainly is not.
PCMark 10 Quick System Drive Benchmark
The Quick System Drive Benchmark writes 23 GB of data over the duration of the test.



Of all the benchmarks we run, it can be argued that this one offers the best reflection of a typical consumer use case scenario. Again, the results here are more than acceptable if the price is right, but in this case, the price is wrong.
Final Thoughts
For the most part, QLC arrayed SSDs offer a bargain to the consumer that is compelling enough to overlook the inherent performance and endurance inferiorities that go hand-in-hand with 4-bit flash. Not this time, though. Priced as it currently is, we simply can't overlook its meager performance, especially its lowest-in-class gaming performance.

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. Currently, we consider a user experience score of 20K or more to verify an SSD as a TweakTown Elite performer.

While we could possibly recommend the drive if it were priced at about half what it currently is, we cannot find even a sliver of sunshine for 4TB of this at $830.
