4TB PCIe 4.0 NVMe drive
This Sabrent Rocket 4 Plus model delivers 4TB of storage on an M.2 2280 card. It uses 3D TLC NAND and a Phison PS5018-E18 controller with DDR4 cache. The drive targets consumers who want high sequential and random throughput for demanding workloads.
Check motherboard PCIe generation and cooling
Verify that your motherboard provides an M.2 slot wired for PCIe 4.0 x4 to reach the rated 7000 MBps read and 6850 MBps write speeds. A PCIe 3.0 slot limits throughput to roughly 3400 MBps read and 3000 MBps write. The supplier notes that a heatsink is required on Gen4 platforms to prevent thermal throttling.
Fits M.2 2280 slots without a heatsink
The drive installs directly into any standard M.2 2280 key-M slot and operates from 0°C to 70°C. It supports NVMe 1.3, APST, ASPM and L1.2 power management plus SMART and TRIM. Free Acronis cloning software and a sector-size utility simplify migration from an existing drive.

Spørgsmål om denne vare
Does the Sabrent Rocket 4 Plus 4TB SB-RKT4P-4TB include a heatsink or do I need to buy one separately?
The drive is sold without a heatsink. The manufacturer states a heatsink is required when installing directly onto a PCIe Gen4 motherboard to avoid thermal throttling and maintain peak performance.
How do I decide between the 4TB Rocket 4 Plus and a smaller capacity in the same series?
Choose the 4TB model if you need the highest capacity with 3000 TBW endurance and up to 650,000 random read IOPS. Smaller capacities in the series typically offer lower total bytes written and may have reduced write performance.
What do the 7100 MB/s read and 6600 MB/s write figures mean for real-world use on a PCIe Gen4 system?
Those are maximum sequential speeds on a PCIe Gen4 motherboard. Large file transfers and game loads will approach these rates, while everyday mixed workloads run at lower speeds. On a PCIe Gen3 board the drive caps at roughly 3400 MB/s read and 3000 MB/s write.
