The Rocket 4 Plus comes in a small, black box. Along with a picture of the drive, the front advertises a few of its key features including its 1TB capacity and PCIe Gen4 x4 interface.


Instead of a flimsy plastic tray or clamshell, the Rocket 4 Plus is packed inside a copper colored aluminum case. Inside this case, you'll find the SSD as well as an installation guide.

Physical Features:

The Rocket 4 Plus uses the 2280 form factor for M.2 (NGFF) SSDs. It measures 80 x 22 x 3.36 mm and weighs in at 9g. The drive also has an "M key" edge connector which provides PCIe SSDs with up to 4x lanes of bandwidth.

The Rocket 4 Plus is one of the first drives to use Phison's new PS5018-E18 controller chip. This PCIe Gen 4 x4 SSD controller is powered by a triple-core ARM Cortex R5 processor with CoXProcessor technology and supports eight channels with up to 32 chip enables (CE) per channel. The E18 also offers features like AES encryption, end-to-end data path protection, SmartECC technology and Phison’s 4th Generation LDPC ECC engine.

For the 1TB version of the Rocket 4 Plus, Sabrent opted to use Micron's 96-layer TLC 3D NAND flash. Underneath the copper colored heat spreader, you'll find four 256GB NAND flash packages as well as a single 1GB SK Hynix DDR4 SDRAM memory chip that is used for caching.
