HDD hard drives for years were the kings of the market as there was no interesting alternative. Years ago the first SSDs arrived, which offer higher read and write speeds, in addition to consuming less and being more resistant to shocks. But, like everything in this life, SSDs are also being replaced.
The SSD are dying without you knowing
You may think that we have gone crazy, but nothing is further from the truth. Surely you will leave us in comments that Amazon is full of SSD hard drives and that they sell like hot cakes. You are not wrong at all, but even so, the solid-state hard drives’ days are numbered.
Before you comment, let us tell you that not all SSDs are dying, but a very specific branch of this type of unit. Specifically, the 2.5-inch SATA SSDs are tending to disappear from the market. And the reason is very simple: they are being replaced by M.2 NVMe PCIe SSDs.
You have an example in PS5 and the Xbox Series Xwhere both consoles use SSD type M.2 PCIeThey don’t use 2.5-inch SSDs. We are also seeing this movement in laptops, since in many cases they use PCIe-based M.2 format units. The explanation for this is as follows:
- The M.2 SSDs take up much less space than the 2.5-inch versions. This allows manufacturers to make lighter laptops with batteries that allow more autonomy.
- The M.2 have much higher read and write speeds to 2.5-inch SATA-based drives
For these two reasons, many manufacturers and assemblers do without 2.5-inch SSDs. It also has to do with cost, as PCIe 3.0-based M.2 SSDs are priced similarly to SATA interface-based drives. Something that is promoting the use of M.2, not only by manufacturers and assemblers, but also by users.
SSDs are dead, long live SSDs
When the first solid-state hard drives arrived, you could already see a logical replacement for the features they offered. It was evident that HDD hard drives, which came to replace magnetic tapes, had their days numbered. The change between 2.5-inch SSDs (which we could also call SATA) and M.2 drives may not be as visible, but it is there.
It is possible that the units 2.5-inch stay for budget laptops and low-cost desktop PCs. It would be something similar to what happened with HDDs, which have been relegated to secondary storage and network storage systems. But everything indicates, due to market movements, that we are heading for M.2 units as predominant.
Note that M.2 SSDs have their advantages, such as eliminating unnecessary wiring, something that is positive. But they have their downsides, and it is that units of this type based on PCIe 4.0 and even PCIe 5.0 have significant temperature problems. Something that causes them to require increasingly larger heatsinks and even with fans to help dissipate heat.
