PlayStation 5 disk controller revealed. The mystery of the Kraken algorithm is still unsolved

Until now, the mass memory of the PlayStation 5 is still quite a mystery, which Sony does not talk about much. However, today the well-known researcher of semiconductor systems (Fritzchens Fritz) provided us with the answer to the question of what PlayStation 5 disk controller Sony used in its internal SSD.

We just got to know the creator who corresponds to the PlayStation 5 disk controller … and so what?

According to the latest discovery, apparently Sony has enlisted the help of a third party to improve the mass memory of the PlayStation 5 console. So far, we knew that the drive used in it had been developed with a special Kraken compression algorithm to reduce file sizes and increase performance. The Sony compression technology itself is clearly patented, but that doesn’t mean the company developed all of the hardware itself. It seems that she asked for help from a well-known manufacturer of SSD controllers – the Marvell company.

The aforementioned researcher uploaded, among others, to the network Photographs taken using an electron microscope that show the PlayStation 5’s CXD90062GG disk controller, which was apparently made by Marvell Technology. This is clearly indicated by the Marvell Titania 2 marking, which additionally makes it clear that the controller was designed in 2018. However, the Titania Marvell controllers are not mentioned anywhere, so they are probably the ones specially made for Sony.

This raises questions as to whether the Kraken algorithm used by the SSD controller in the PS5 was developed by Sony or by Marvell. In the first case, its miraculous performance (reducing the weight of game files up to 60% and increasing read and write performance) will never go beyond the PlayStation ecosystem, but in the second, there are chances that Marvell will someday present a variant of the Kraken algorithm in its controllers for consumer SSD drives.
