Today we are taking a look at the brand new Sabrent Rocket 4 Plus 2TB SSD. This is Sabrent’s second-generation high-performance PCIe 4.0 SSD featuring the new Phison PS5018-E18 controller, and currently represents the flagship of Sabrent’s SSD lineup from a performance perspective.
Sabrent Rocket 4 Plus 2TB
The Sabrent Rocket 4 Plus 2TB comes in a double-sided M.2 2280 (80mm) form factor.
Much like previous Sabrent drives, the drive label is applied on top of a thin copper heat spreader. Beneath the label and heatspreader there is the Phison PS5018-E18 controller, a DRAM cache, and 4 Micron 96L 256GB NAND packages.
The back has a product information label, and beneath that the other 4 256GB NAND packages. That brings the total NAND on the drive to 2048GB, which leaves 48GB reserved by the controller. This configuration is very common on consumer 2TB SSDs.
Sabrent Rocket 4 Plus Specs
The Sabrent Rocket 4 Plus line of TLC-based SSDs has been announced in sizes ranging from 1TB to 4TB, but as of writing this review the 4TB units are not yet available.
With the 4TB unit not yet available, that leaves our 2TB drive as the top available SKU with a very high rated performance of 7100 MB/s sequential reads and 6600 MB/s sequential writes. Additionally, the 1400 TBW endurance represents a slightly higher rated endurance over some other 2TB drives like the WD Black SN850 and Samsung 970 EVO Plus 2TB, both of which clock in at 1200 TBW. However, even at 1400TBW this represents a big step down in rated endurance from Sabrent’s previous-generation Rocket NVMe 4.0 2TB drive, which had a significantly higher 3600 TBW endurance rating. Still, we can take a pause here and just mention that it would be very unlikely that a M.2 SSD like this would see over a petabyte of writes to it over five years unless it was being used in an application it was not intended for.
CrystalDiskInfo can give us some basic information about the SSD, and confirms we are operating at PCIe 4.0 x4 speeds using NVMe 1.4.
Test System Configuration
We are using the following configuration for this test:
- Motherboard: ASUS PRIME X570-P
- CPU: AMD Ryzen 9 3900X (12C/24T)
- RAM: 2x 16GB DDR4-3200 UDIMMs
Our testing uses the Sabrent Rocket 4 Plus 2TB as the boot drive for the system, installed in the M.2_1 slot on the motherboard. The drive is filled to 85% capacity with data and then some is deleted, leaving around 60% used space on the volume.
Next, we are going to get into our performance testing.
