SK hynix Platinum P41 SSD Review – Can Gen4 Get Any Better than This?


SSD testing at TSSDR differs slightly, depending on whether we are looking at consumer or enterprise storage media. For our SK hynix Platinum P41 2TB Gen4 NVMe SSD testing today, our goal is to test in a system that has been optimized with our SSD Optimization Guide.

For this Test Bench, the CPU C-States, Enhanced Intel SpeedStep Technology (EIST) and Intel Speedshift (P-States) have not been disabled. As you will see below, the system is also bumped to 5.1GHz with memory at full speed in its XMP 2 profile.


The components of this Test Bench are detailed below. All hardware is linked for purchase and product sales may be reached by a simple click on the individual item.

The software in use for today’s analysis is typical of many of our reviews and consists of Crystal Disk Info, ATTO Disk Benchmark, Crystal Disk Mark, AS SSD, Anvil’s Storage Utilities, AJA, TxBench, PCMark 10, 3DMark, PassMark Performance Test, Final Fantasy XIV Gaming BenchMark, as well as true data testing. Our selection of software allows each to build on the last and to provide validation to results already obtained.


Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.


Crystal DiskInfo validates that our SSD is running in PCIe 4.0 x4, using the NVMe 1.4 protocol and confirms that it is TRIM capable.


ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.


ATTO performance hits highs of 6.67 GB/s read and 6.23 GB/s write are would we might expect from this SSD in this specific bench.  It is also good to see solid and consistent data throughput progression as sample sizes increased.

    Nowhere in this review did you mention temperatures, requirements for a thermal solution, etc.

    Would this be a good option for a PS5? Does it run too hot?

    Can someone explain to me why no one makes and sells SLC SSDs today, even though Chinese SSDs on Chinese TLC memory cost a penny? What prevents switching NAND chips from TLC mode to permanent SLC mode, albeit with a loss of 2/3 capacity? But the speed is always the same as in SLC mode and an indestructible resource, plus a data storage time of at least 10 years.

    What would a smart buyer prefer if they were offered a 2TB 3D TLC SSD for $100 or a 666GB SLC drive for the same price? Well, yes, I am aware that most people are idiots and marketers rule them …

      It’s not a loss of 2/3 of capacity. SLC > MLC > TLC means 2^n so it’s actually 3/4 capacity loss. Basically, it would cost 4 times as much. You also have to consider that NAND density is a huge issue as well.
