Test system and test preparation
I use the usual suspects such as CrystalDiskMark and Atto to check the theoretical data from the specs. Due to previous workstation tests, these are no longer brand-new SSDs, but everyday goods that have also already been worn down quite a bit. Let’s see what remains of the theory in everyday life after the wear and tear. The SSDs to be tested are located in the first PCIe 5.0 NVMe slot of the motherboard and are not used as system disks.
I also 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 remains with the large workloads. However, I picked out the applications with the biggest differences and loads as examples. I have also summarized the individual components of the test system in a table:

Sequential performance of the used SSDs
The synthetics are a good way to really run out the big numbers. We will see later how well this works in reality with the real application benchmarks. That’s why I’m starting with CrystalDiskMark and four different file sizes. The SSD was no longer new at the time of testing (I always run these tests at the end for certain reasons) and I had already had fill levels of around 50% before deleting the data several times.
This certainly also explains the fact that you can miss the maximum values a little when writing, but still have impressive figures. This is probably why the phrase “up to” was used.
You can see very clearly that the dynamic pSLC does exactly what it is supposed to do, mind you with an empty (albeit not virgin) SSD. The nice thing about the 2 TB SSD is that there is plenty of space and you should therefore never fill it more than 2/3 full with data. A higher load does not affect reading, but the dynamic SLC will certainly reach its limits when writing. And if you do it over and over again, at some point it will no longer be possible to switch the memory modules between the two methods.
ATTO works in a very similar way, although I only work with two sizes here, which ultimately results in the same thing. You only just miss the limit of 7000 MB/s, but it is still enough for an impressive result.
But what happens when you stream a video? The industry uses the AJA benchmark for this, which is effectively an interface between synthetic benchmarks and practical applications. Here, too, the MP700 Pro does not fall short, although it does deviate somewhat from the theoretical write and read rate. Let’s first look at the writing process of the encoded video content and then compare the whole thing with its predecessor in the table:
Reading is also quite brisk, although here too you don’t reach the theoretically possible speed. But almost. And the new Pro version is really fast.
I have attached a detailed AJA protocol for you:
