The HDD is the only user-serviceable part in the PS4, perhaps USB was chosen over PCIe SATA to make theoretical DMA attacks on the system more difficult?

- magila 11y agoSATA doesn't give you direct access to the DMA engine, the host decides where the data from the drive goes. If anything USB is probably more exploitable.
- snuxoll 11y agoWell, the SATA controller has DMA access with the host. Of course, you have to find some way to trick the controller into misbehaving, but it's possible.
- Ezhik 11y agoThat would be funny, considering that the original PS3 Jailbreak exploited bugs in Sony's USB code.
