Sabrent Rocket 4 Plus 4TB Review

Rating: 9.0.

Sabrent's current flagship for the Rocket 4 Plus SSD series is the 4TB model. We've already looked at the 1TB and 2TB drives that make up the rest of the family, so let's see how the big one stacks up. Can it justify an asking price of almost £800?

The 4TB Rocket 4 Plus heads up a three drive range, the other two being 1TB and 2TB capacities. At the heart of the drive is a second-generation Phison PCIe Gen 4 controller, the PS5018-E18. In the case of the 4TB model, this looks after eight packages of 96-layer 3D TLC NAND and a couple of DRAM cache chips.

Sabrent quote Sequential read/write speeds for the 4TB drive as up to 7,200MB/s and up to 6,900MB/s respectively. 4K random performance is listed as up to 650,000 IOPS for reads and up to 700,000 IOPS for writes.

Sabrent rate the endurance of the 4TB drive at 2,800TBW and back the drive with a 1-year warranty although if you register the drive with them you get a full 5-year warranty.
