300TB SSDs are just around the corner, but…

Today, it does not escape anyone who knows solid state drives that storage capacity is not among its strengths compared to hard drives. That is why talking about a 300 TB SSD sounds like a pipe dream today, however, all this depends on the context and the fact is that the statement has a certain trap.

We’ve always said that the best SSD for us would be one with the same size as a 2.5-inch drive, but with the speed and bandwidth of an M.2 type. In other words, it encompasses the best of both worlds. This already exists in U.2 connectors, but unfortunately PC motherboards do not have such a connector, which is more common in servers or data centers.

300TB SSDs are just around the corner

Will we see a 300TB SSD in 2026?

At least this is what Pure Storage , a company dedicated to the manufacture of storage devices based on flash memory, affirms when it talks about its proprietary format, called Direct Flash Module , which will allow them to have 300 TB SSD drives. Sounds good right? Well, the cold water jug is that they are designed to work only in their data centers , so not only you can’t install them on your PC , but you can’t install it on a server either, even if it has a U.2 interface.

SSD 300 TB

As you can see in the image, the drive is not exactly small in size and even larger than a 2.5-inch SATA SSD, all in order to contain a large number of TLC or QLC type flash memory chips that would allow it to reach the drive to 300TB in 2026, which is when the capacity of commercially available chips is high enough. In any case, as we have said before, it is not intended to be installed in a walk-up computer and it does not respect the standard form factor of the units on the market.

However, this opens up the possibility of a similarly high-performance unit for PCs, even if all we can think of is something in the form of a graphics card, but instead of housing a GPU and its VRAM, it houses the flash controller, 3D NAND chips, and corresponding RAM. All this with a heatsink with a fan on top in order to keep the unit cool. However, most users will continue to use M.2 modules as they do not need such large amounts of storage.

The devil is in the details

One of the ways in which we will see an increase in the capacity of SSDs will be in the fact that they will have real-time data compression and decompression mechanisms, which will allow them to store more information than they physically could in principle. This ability to encrypt and decrypt data would be integrated into the flash controller of the different drives, thereby increasing storage capacity without having to rely on higher capacity NAND Flash chips. All this is something that we hope to see in each and every one of the units as a common characteristic that will be integrated in the coming years.
