Today we are taking a look at the SK hynix Platinum P41 1TB NVMe SSD. The Platinum P41 is the PCIe 4.0 successor to the Gold P31, which for me has long been the standard-bearer for PCIe 3.0 drives. That gives the P41 some big shoes to fill, and competition is already tight at the high-end for PCIe 4.0 drives, so we will see how the P41 manages to stack up.
SK hynix Platinum P41 1TB NVMe SSD
The SK hynix Platinum P41 1TB comes in a single-sided M.2 2280 (80mm) form factor. Most other PCIe 4.0 SSDs come with the option of a heatsink, while the P41 does not. Keep that in mind when we get around to thermal testing.
The SK hynix Platinum P41 bundles 176-layer TLC NAND with SK hynix’s new “Aries” controller. Unlike the P31, the controller on the P41 appears to be a 8-channel design, which matches most other high-end SSD controllers. Also included is a DDR4 DRAM cache, with the 1TB drive featuring 1GB of cache.
The rear side of the drive has nothing except some silkscreened logos and regulatory markings.
SK hynix Platinum P41 SSD Specs
The SK hynix Platinum P41 line of SSDs is available in sizes between 500GB and 2TB.
Today we are looking at the 1TB model, which is rated at 7000 MB/s sequential read and 6500 MB/s sequential write. These specs target the P41 squarely at the highest end PCIe 4.0 drives, so expectations will be high when it comes time to benchmark. Rated endurance for the 1TB drive is 750 TBW, which ties the P31 and is above average for most of the 1TB SSDs that I review. Lastly, the drive comes with a standard 5-year warranty which is the preferred length of warranty for a premium drive.
CrystalDiskInfo can give us some basic information about the SSD and confirms we are operating at PCIe 4.0 x4 speeds using NVMe 1.4.
Test System Configuration
We are using the following configuration for this test:
- Motherboard: ASUS PRIME X570-P
- CPU: AMD Ryzen 9 5900X (12C/24T)
- RAM: 2x 16GB DDR4-3200 UDIMMs
Our testing uses the SK hynix Platinum P41 1TB as the boot drive for the system, installed in the M.2_1 slot on the motherboard. The drive is filled to 85% capacity with data and then some is deleted, leaving around 60% used space on the volume.
Next, we are going to get into our performance testing.
