Be careful if you plan to buy a Gen5 SSD. You should keep in mind two very important things.
The next generation SSDs are already here. Called PCIe 5.0 SSD either SSD Gen5and are twice as fast as the previous generation. They reach speeds of 12,000 MB/s… until, suddenly, drop to 100 MB/s… like an old hard drive.
The reason, surely you have already guessed. In technology, more speed means more heat. Gen5 SSDs get even hotter than a processor or a powerful graphics card.
The German website ComputerBase has analyzed two of the first PCIe 5.0 SSDs that have hit the market: Corsair MP700 and Crucial T700. These NVMe SSDs reach speeds of up to 12,000MB/swhich means that they almost double the previous generation Gen4, which reaches 6,000 or 7,000 MB / s.
The big problem with Gen5 SSDswhich does not affect only these two models, but all of them, is that they get very hot. In ComputerBase tests, to reach 12,000 MB/s its temperature rises to…86 degrees Celsius!
The Corsair model, upon reaching 87 degrees, stopped working. Crucial’s continued to do so, but its speed dropped to 100 MB/sas we can see in these benchmarks:
ComputerBase
As we see, at standard temperatures it achieved an incredible 12,385 MB/s. But when he reached 86 degrees down to 101 MB/sand even fell to the 53 MB/s. That’s the speed of a slow old hard drive of a lifetime.
The solution is put a heatsink on the SSD Gen5. The big problem, and this is the responsibility of the manufacturers, is that since PCIe 5.0 SSDs are expensive, andThe heatsink is sold separately, as an option. And optional has little, as we are seeing. The heatsink should be included with all Gen5 SSDs.
An additional problem is that Gen5 SSD coolers are huge:

PCIe 5.0 motherboards come ready to fit them, but if you’re using an older PC case, you have to check that there is a free space in the space where the SSD goes.
The conclusion is simple. Gen5 SSDs heat up to 86 degrees Celsiusso if you are going to use one you should make sure that you put a heat sinkand of what the cooling of your PC is top quality, because this heat is joined by that of the processor, the GPU, the memory, and the rest of the components. Otherwise, instead of a Gen5 SSD you will have the most expensive hard drive in the world.
