The advent of PCIe 5.0 SSDs with Phison's E26 controllers has been a double-edged sword. While these SSDs offer impressively high data throughputs, they come with a significant drawback: severe overheating issues that can cause the SSDs not only to throttle down but to shut off entirely. TechPowerUp first noted this issue back in May, in our Corsair MP700 review, where the uncooled drive shut down after 86 seconds of reads and after 55 seconds of writes. Regarding criticism from tech reviewers, Corsair has released a firmware update (version 22.1) for its MP700 SSD to ensure that it throttles down rather than shutting off when overheated. Yet, many other SSDs like the Crucial T700, Seagate FireCuda 540, Gigabyte Aorus Gen 5 10000, and ADATA Legend 970 still suffer from temperature issues.

However, it's crucial to note that these extreme overheating problems occur only when the SSDs run without any cooling. While some manufacturers have planned firmware updates to address the issue, Corsair is the only company that has taken tangible action so far. Crucial has released a new firmware (PACR5102), but the ComputerBase report indicates that the SSD continues to shut off at high temperatures. The problem, though, can generally be mitigated with proper cooling. Whether using the included cooler or placing the SSD under a motherboard cover, temperatures usually stay below the critical limit, thus avoiding a complete shutdown. When we tested the SSTC Tiger Shark Elite 2 TB with Phison E26 (with updated firmware) without adequate cooling, the SSD continued to operate and throttled down, indicating that the remaining SSDs using this controller need a proper firmware update that throttles the SSD instead of shutting it down.

Seagate Technology Holdings today introduced the next generation of SSD technology to its lineup, the FireCuda 540. The PCIe Gen 5 NVMe SSD delivers unparalleled performance to gamers, creators, and tech enthusiasts - adding the fastest speeds and endurance to the company's line of PC storage products.

Seagate's fastest and highest performance M.2 2280 SSD, the FireCuda 540 delivers sequential read speeds of up to 10,000 MB/s and sequential write speeds of up to 10,000 MB/s. Built for sustained, pro-level gaming and accelerated content creation, the new drive performs up to 50% faster than Gen 4 M.2 NVMe drives and 17 times faster than SATA-based SSDs. With the latest 3D TLC NAND technology and built with a Seagate-validated E26 controller, the FireCuda 540 provides the most advanced speed and durability - allowing users to push limits when gaming or creating content. Plug-and-play compatible with all PCIe Gen 5 motherboards and backwards compatible with PCIe Gen 4, the drive is accessible and ready for trailblazing.

Not entirely unexpected, Seagate is getting ready to launch its first PCIe 5.0 NVMe SSD which will be going under the name of FireCuda 540 and now details of the upcoming drive have appeared online courtesy of Amazon UK, B&H Photo and others that have put up the product for pre-order. For those worried about the lack of a 4 TB SKU, you can relax, as the company is planning a 4 TB SKU, which is made clear from the pictures posted by Amazon UK. However, changing the digit in the model number that represents the drive size, doesn't bring up any info about a 4 TB SKU at the moment.

It doesn't look like the FireCuda 540 will be competing with the fastest PCI 5.0 NVMe drives, as it's only listed as offering sequential drives speeds of up to 10 GB/s, although this applies to both read and write speeds for the 2 TB SKU, with the 1 TB SKU being somewhat slower with read speeds of 9.5 GB/s and write speeds of 8.5 GB/s. The 1 TB SKU is good for 1,000 TB TBW, with the 2 TB SKU doubling this to 2,000 TB and the 4 TB SKU apparently hitting 3,949 TB or as Seagate put it, this allows you to erase 90 percent of the drive every day for five years. B&H Photo has the drives listed at US$189.99 for the 1 TB SKU and US$319,99 for the 2 TB SKU—making both SKUs cheaper than Crucials T700—with Amazon UK listing the 1 TB SKU for £203.48 and no pricing for the 2 TB SKU. It's unclear when the Seagate FireCuda 540 will launch, but it can't be far away.
