Test system and test preparation
To check the theoretical information from the specs, I use the usual suspects like CrystalDiskMark and Atto. However, I don’t make it quite easy even for these programs, because the SSDs were written several times with about 66 es of storage. Thus, these are not brand-new SSDs, but rather everyday goods that have already been properly run down. Let’s see what remains of the theory in everyday use after the wear. The SSDs to be tested are in the second NVMe slot of the motherboard and are not used as a system disk.
In addition, I use AJA as an everyday test to simulate the encoding of larger Ultra HD video streams and the SPECwpc storage test, which contains a lot of real applications and it will be interesting to see what performance is left for the large workloads. However, I picked out the applications with the biggest differences and loads as examples here. The whole thing runs on my current small workstation with the Ryzen 9 5950X and the MSI MEG X570 Godlike including 32 GB DDR4 3800.
I have also summarized the individual components of the test system in a table:

Sequential performance of used SSDs
Synthetics are a good way to really show off the big numbers. We will see later how well this works in reality in the real application benchmarks. Therefore, I’ll start with CrystalDiskMark and four different file sizes. The SSD was no longer new at the time of testing (I always do these tests at the end for certain reasons) and I also had fill levels of plenty of 50% before deleting the data several times.
This certainly also explains that one misses the maximum values by quite a bit, but can still show impressive numbers. That’s certainly the reason for the “up to” wording. Let’s first look at the new MSI SPATIUM M480 2TB Pro in comparison to the “original model”

You can see very well that the dynamic pSLC does exactly what it is supposed to, mind you with an empty (though not virgin) SSD. The nice thing about the 2 TB SSD is that there is a lot of space left, so it is better to never fill it more than 2/3 with data. A higher load does not affect reading, but the dynamic SLC will definitely reach its limits at some point during writing. And if you do it over and over again, the switch of the memory modules between the two methods will also no longer be possible at some point.
ATTO also works in a very similar way, although I only work with two sizes here, which ends up in the same way. You only just miss the limit of 7000 MB/s, but it is still enough for an impressive result. And by the way: the numbers, as well as the CrystalDiskMark, coincide with the “Play” version. Well…

But what happens when you stream a video? For this, the industry uses the AJA benchmark, which is effectively an interface between synthetic benchmarks and practical application. The Spatium M480 Pro does not fluff here either, even though it already deviates a bit from the theoretical write and read rates. Let’s first look at the write process of the encoded video content and then compare the whole thing in the table with the predecessor:
The older SSD remains a tad slower on average in all respects, and the “Play” can also be narrowly beaten in writing.
| MSI SPATIUM M480 2 TB NVMe Pro | MSI SPATIUM M480 2 TB NVMe |
|
| Resolution: | 4K RED HD | |
| File Size: | 64 GB | |
| Codec : | 16bit RGBA | |
| Video file: | Movie | |
| Write rate | 134 frames/second | 98 frames/second |
| Write rate | 6361 MB/second | 6206 MB/second |
| Minimum rate | 3039 MB/sec | 3188 MB/sec |
| Maximum rate | 6594MB/sec | 6447 MB/sec |
Reading is also quite fast, although you don’t reach the theoretically possible speed here either. But almost. And the new Pro variant is superior to the older SSD in all aspects:
| MSI SPATIUM M480 2 TB NVMe PLAY | MSI SPATIUM M480 2 TB NVMe PLAY | |
| Write rate | 100 frames/second | 97 frames/second |
| Write rate | 6397 MB/second | 6185 MB/second |
| Minimum rate | 6097MB/sec | 5987 MB/second |
| Maximum rate | 6443 MB/sec | 6317 MB/sec |
We can see that the comments made on the previous page about the dynamic pSLC cache and the behavior with larger file blocks are completely true. Smaller file movements would indeed be even faster if the overhead of the file system is left out for a moment.
