Sabrent Rocket 4 Plus-G (PCIe 4.0 NVMe/5,000 MB/s Read/4,200 MB/s Write/DRAM-less Gen4 Value Pick) Review
The Sabrent Rocket 4 Plus-G is a DRAM-less PCIe 4.0 NVMe drive built around an InnoGrit controller, positioned as Sabrent's budget Gen 4 option below the full Rocket 4 Plus.
It trades a dedicated DRAM cache for Host Memory Buffer support, which keeps the price down while still comfortably beating any SATA drive, making it a sensible pick for a secondary game drive rather than a primary OS or content-creation volume.
Performance and Speed
5,000 MB/s read and 4,200 MB/s write are solid mainstream PCIe 4.0 numbers, well ahead of any SATA SSD and adequate for game load times, general responsiveness, and everyday file work.
DRAM-less Design Trade-offs
Using Host Memory Buffer instead of onboard DRAM keeps manufacturing costs down but means performance can dip under long sustained write sessions, like copying hundreds of gigabytes at once, compared to a DRAM-equipped drive at a similar price.
Comparison to Sibling Products
Against the WD_BLACK SN770, also DRAM-less and covered elsewhere on this site, the two compete directly on price and specs, with the choice usually coming down to whichever is cheaper on a given day. Against Sabrent's own Rocket 4 Plus, the full DRAM-equipped model handles sustained writes noticeably better and is worth the upgrade for anyone doing regular large file transfers.
Who This SSD Is Actually For
Budget builders adding a fast secondary game drive. This is exactly the workload where the DRAM-less design's limitations matter least.
Anyone upgrading from SATA on a tight budget. Even without DRAM, this drive is a massive real-world speed jump.
Not for content creators moving very large files regularly. Sabrent's own Rocket 4 Plus, covered elsewhere on this site, sustains write speed far better.

Expert rating7.2 / 10
A sensible budget Gen 4 drive that does exactly what it's priced to do; skip it if you need sustained write performance.
Best for
- Budget builders adding a fast secondary game drive. This is exactly the workload where the DRAM-less design's limitations matter least.
- Anyone upgrading from SATA on a tight budget. Even without DRAM, this drive is a massive real-world speed jump.
- Console-style handheld PC upgrades where cost per gigabyte matters more than peak sustained throughput.
Not for
- Not for content creators moving very large files regularly. Sabrent's own Rocket 4 Plus, covered elsewhere on this site, sustains write speed far better.
- Not for a primary OS drive on a heavily multitasked workstation. The lack of dedicated DRAM shows up under sustained load.
- Not for buyers chasing the fastest possible numbers at this price. Several DRAM-equipped competitors land in the same price range.
