PS5-ready expansion with heatsink

The Sabrent Rocket 4 Plus 4TB internal SSD includes a CNC aluminium heatsink built to replace the console's native cover. This design uses a sandwich construction to apply even pressure across the drive for consistent heat transfer. The bundle fits the PS5 expansion slot directly for a quick installation.

Heatsink replaces the stock cover

Unlike add-on sinks that trap heat under the metal lid, the supplied heatsink becomes the new cover and works with the PS5's internal fan. This arrangement improves airflow over the controller and NAND during extended play sessions. The drive therefore sustains its rated speeds without thermal throttling.

PCIe 4.0 x4 interface limits

The drive connects through a PCIe 4.0 x4 lane, delivering up to 7000 MBps sequential read and 6850 MBps sequential write. Random performance reaches 650000 IOPS read and 700000 IOPS write. Endurance is rated at 3000 TBW with an MTBF of 1600000 hours. Operating temperature range is 0 °C to 70 °C.

Questions about this item

Does the included heatsink fit inside the PS5 expansion slot without modification?

The heatsink replaces the console's native cover and is designed to fit the PS5 expansion slot directly, using the system fan for airflow.

Will the drive meet the console's minimum 5500 MB/s read requirement?

Sequential read reaches up to 7000 MB/s and write up to 6850 MB/s, exceeding the 5500 MB/s threshold.

What endurance rating does the 4 TB model carry?

The drive is rated for 3000 TBW with an MTBF of 1,600,000 hours.
