SK Hynix Platinum P41 review (2023) does an incredible job

This 2 TB drive is rated for a write endurance of 1,200 TB.

The SK hynix Platinum P41 is the company’s newest 22x80mm M.2 form factor NVMe SSD for consumers. It is also their first Gen4 SSD with 176-layer NAND. The P41 is a low-cost drive with storage capacities of up to 2TB and an ACNS075 PHC631.00S-1 controller. It was made with power efficiency and consistent performance in mind. This build makes it perfect for people who make content and want a fast NVMe Gen4 solution for their PC.

SK Hynix Platinum P41: Description

In this year, we looked at the SK hynix Gold P31, which was the first 128-layer NAND flash-based consumer Gen3 SSD on the market, and were impressed by how well it balanced price and performance. In this review, we’re hoping to see SK’s Platinum P41 continue in the same way.

The SK hynix Platinum P41 is said to be able to read up to 7.0GB/s at all capacities and write up to 6.5GB/s at the higher capacities, which is twice as fast as the P31 can read or write. The 500GB model is said to have a write speed of 4.7GB/s. For random 4K reads, the 1TB and 2TB capacities should hit up to 1.4 million IOPS for reads and 1.3 million IOPS for writes. The 500GB model is said to have a read speed of 960,000 IOPS and a write speed of 1,000,000 IOPS.

Design and Features

SK Hynix Platinum P41 review

There’s not much to see here in terms of design. The SK Hynix Platinum P41 2TB is an M.2 drive with only one side and no heatsink or spreader. For PC, that’s fine and might even be better since many high-end motherboards have cooling for SSDs. It is more of a possible problem for the console. Again, don’t think that.

The SK Hynix Platinum P41 2TB has the same specs as the SK Hynix Gold P31, which was a Gen 3 drive, except that it supports PCIe Gen 4. Also, the new P41 has a new chip called the SK Hynix Aries, which is a controller chip. It doesn’t just change the PCIe spec of the drive. It also doubles the number of memory channels from four to eight, which is needed to compete with the fastest M.2 drives. The Aries chip also has 2GB of DDR4 cache memory and twice as many cores as SK Hynix’s previous controller.

The P41 has the latest and greatest 176-layer 3D TLC NAND flash memory chips from SK Hynix. SK Hynix thinks that it is about 40% faster than its older 128-layer technology. This 2TB model is said to have sequential read speeds of 7,000MB/s and sequential write speeds of 6,500MB/s. The drive’s write speed is a little bit slower on the smaller versions.

Of course, most Gen 4 drives say they have the same write speed. The only place where a drive can really stand out from the rest is in its random access or IOPS performance. SK Hynix says that the P41 can read 1.4 million IOPS and write 1.3 million IOPS, which are both very good numbers. The last piece of the SSD puzzle is its ability to last.

The 2TB P41 has a write endurance of 1,200TB. Some of the competition, like the Seagate FireCuda 530, can write up to 2,550TB, which is a lot more than that. On the other hand, it makes that 1,200TB number easier to understand. It’s enough to write hundreds of GB every day for decades. So, it could be a difference in the classroom. The P41 also has a five-year warranty, which is about the same as what the other brands offer.

SK Hynix Platinum P41: Performance

SK Hynix Platinum P41 review

The SK Hynix Platinum P41 works very well. In my tests, the numbers were very close to what the company said they would be. The manufacturer says that the 2TB version can read at up to 7000 MB/s and write at up to 6500 MB/s. This would make this drive one of the best all-arounders to date. CrystalDiskMark reported read speeds of 6549.75 MB/s, which is very good.

We didn’t think the sequential performance was quite up to 7000 MB/s, though. I got write rates of 6164.07, which are very close to the top of what the form factor can do. This is confirmed by Anvil Pro, which gives this drive a total score of 23,121.18, which means it can handle data going both ways. Performance at random is just as strong. SK Hynix says the Platinum P41 SSD can reach random read and write speeds of up to 1,400K IOPS and 1,300K IOPS, respectively.

During my tests, I found that this model worked well at rates of 1,115K and 885K each. In real-world applications, though, the speed at which files are moved is lightning fast. For comparison, the 59GB of data for Street Fighter V moved from another Gen 4.0 drive to the Platinum P41 in just under 20 seconds, which is about 3GB/sec.

Things are a little more stable when the file sizes are smaller. For example, it took just 7.3 seconds for the File Explorer to move 7GB of images from one drive to another. That’s about 1GB per second, which means that the speed goes up with the size of the games and files being moved. So, in terms of gaming performance, this means that games like Halo Infinite, which are made for Gen 4.0 speeds, will have almost no loading times. This is really fast stuff.

Price and availability

SK Hynix Platinum P41 review

The Platinum P41 was sent to Windows Central for review by SK Hynix. It is a PCIe 4.0×4 NVMe SSD that comes in sizes of 500GB, 1TB, and 2TB. I’m looking at the 2TB version. About $105 will get you the 500GB version, $150 will get you the 1TB version, and $260 will get you the 2TB version. The SSD is easy to get from Amazon. It does not have a heatsink built in you can buy this product directly from amazon.

The Platinum P41 works with PCs that support PCIe 4.0, but it will also work with PCIe 3.0 at a lower performance level. If you’re still using the older standard and don’t plan to switch any time soon, you should check out more of the best SSDs with PCIe 3.0. Even though you will need to add a heatsink, the Platinum P41 will also work with the PlayStation 5.

Final words

When we tested SK Hynix’s first PCI Express 3.0 solid-state drive, the Gold P31, last year, we were impressed, so we had high hopes for the Platinum P41. It was even better than we could have imagined. When we first saw the P41’s test results, we couldn’t believe it. There were so many new records! Just before publishing, we looked at the first few reviews of the drive on other sites to make sure they were accurate.

Most of the time, we couldn’t directly compare results because each site uses a different mix of benchmarks and comparison drives, as well as its own testbed that is set up in a different way. But they confirmed that this SSD can beat other high-performance PCI Express 4.0 drives in terms of performance.


Is SK Hynix Platinum P41 good for gaming?

The SK hynix Platinum P41 PCIe 4.0 SSD comes out ahead of other SSDs we’ve tested in almost every benchmark. It’s competitively priced, it has an excellent TBW rating, and it’s available in three capacities. It’s an easy recommendation if you want an upgrade for gaming or for productivity.

Does SK hynix Platinum P41 need a heatsink?

In some of our general storage and game tests, the SK Hynix Platinum P41 got record-high scores. It’s a great deal for an M.2 SSD; just add your own heatsink to make sure it works at its best.

Is SK Hynix RAM good for gaming?

Some of Hynix’s RAM chips, like the CJR and DJR, are great for gaming. However, these chips are usually not as good as the best Samsung B-die and Micron Rev. B/E chips. No. Micron 16Gb Rev. D is the second-best RAM chip for gaming, after Samsung 8Gb B-die.

Is Hynix chip good?

How bad is Hynix, really? No, Hynix is awesome. They give the Enterprise a lot of memory chips and modules. Many of the systems I work on use memory made by Hynix and Samsu
