Being a faster version of the Rocket 4, the Rocket 4 Plus uses Phison's PS5018-E18 SSD PCIe 4.0 controller paired up with TLC NAND flash, hitting impressive sequential read and write performance of up to 7000MB/s for read and up to 6850MB/s for write.

The Rocket 4 Plus will be available in 500GB, 1TB, and 2TB capacities.

In order to deal with all the heat from such performance, Sabrent has come up with a custom heatsink, which combines an aluminum heatsink with copper heat coils. The complete heatsink also includes thermal tape, an aluminum tray, and a top heatspreader. According to Sabrent, this should prevent all thermal throttling, pushing it to maximum performance.

Unfortunately, the product page did not include 4K random read and write performance and we still do not have a price nor the availability date, but it will be interesting to see how well it does in detailed benchmarks.
