SK Hynix might dethrone Western Digital with this SSD

SK Hynix has just announced the release of a brand-new PCIe Gen 4.0 SSD that should prove to be one of the best SSDs in terms of input/output operations per second (IOPS).

Set to potentially become one of the fastest such drives on the market, the SSD is already available on Amazon. However, as is the case with many other SSDs, not every variant of the SK Hynix Platinum 41 will offer such top speeds.

The new SK Hynix Platinum 41, at its most capable, comes with sequential speeds of up to 7000MB as well as capacities reaching as high as 2TB. It truly shines where IOPS are concerned, though, seeing as it’s rated for 1.4 million random read IOPS and 1.3 million random write IOPS. Although those numbers don’t make it the fastest SSD in 2022, it certainly has a chance to climb the ranks and land near the top among brands such as Kingston and Western Digital.

SK Hynix also breaks new ground with this SSD due to the 176-layer NAND flash — it’s the first consumer-based drive to utilize this kind of technology, and it delivers a huge upgrade, stepping up from 128-layer NAND. This adds up to a 20% increase in read cell speed as well as 1.6GT/s of bandwidth between the NAND flash and the SSD controller.

This kind of performance jump could definitely be felt by the end users in daily performance. Be it in gaming or various other workloads, the benefit from an increase in random read and write speeds could be significant. The data on an SSD’s NAND flash is rarely ever neatly organized, which means that the drive has to not just transfer data, but also locate it first. Upping the random read and write speeds should combat this problem to an extent, resulting in faster performance.

As mentioned above, the SK Hynix Platinum 41 is already available on Amazon in three capacities: 500GB for $105, 1TB for $150, and 2TB for $260. All of the models are rated for maximum read speeds of 7000Mbps, which is the maximum PCIe Gen 4 can provide, but the write speeds vary by capacity — the better the model, the higher the write speeds.

SK Hynix has not released the exact random read and write speeds for each individual model, but it seems safe to assume that the same logic will apply here, with the higher-priced versions receiving the best speeds.

The cheapest, 500GB model has a write speed of just 4,700Mbps. Both the 1TB and the 2TB variants can hit at high as 6,500Mbps. The lifespan of the SSD is also reduced or enhanced based on capacity, with the 500GB version rated at 500TBW, the 1TB version at 750TBW, and last, 1,200TBW for the 2TB model.

This SK Hynix Platinum 41 SSD was first spotted by Tom’s Hardware. Until it is thoroughly benchmarked, it’s hard to know how high it will rank among the best SSDs, but on paper, it sounds like it will be one of the better options available on the DIY market.

How Apple plans to save the Vision Pro
A person wearing an Apple Vision Pro headset.

It’s no secret that Apple’s Vision Pro headset is the best advanced headset on the market, with powerful specs and an immersive experience that no rival can truly match. It’s also no secret that Apple has struggled to sell its device, given its $3,499 price tag puts it way out of reach of most consumers. Apple reportedly has a plan to turn things around, though -- yet it might not involve a Vision Pro headset at all.

According to the latest Power On newsletter from Bloomberg reporter Mark Gurman, Apple plans to launch a cheaper Vision Pro in late 2025 at the earliest, followed by a second-generation mainstream Vision Pro around late 2026. After that is a set of much-discussed augmented reality (AR) glasses, although Gurman believes these are still many years away.

4 video editors you should use instead of Adobe Premiere Pro
Someone using the Surface Laptop Studio 2 with Adobe Premiere Pro.

Adobe Premiere Pro is the go-to video editor for many, and it's no wonder. It's an extremely powerful utility with a massive community of users and developers that works both on Windows and Mac. Not only do you get an extensive list of features and tools within the app itself but also the backing of hundreds of third-party plugins and tutorials. There's just one problem: It's expensive.

You'll spend $23 per month just for Premiere Pro. If you need any other Adobe App -- be it Adobe Media Encoder, Photoshop, or After Effects -- you'll spend $60 month, and that's if you commit to subscribing for a year. Adobe's Creative Cloud suite, including Premiere Pro, is powerful, but there are some alternatives that let you get your foot in the door for much less. Here are four Premiere Pro alternatives you should consider.
