The Addlink G55H is the fastest DRAM-less PCIe 5.0 SSD we’ve tested so far, offering a compelling blend of performance and affordability. While the real-world speed gains over PCIe 4.0 are minimal at present, this drive represents an excellent entry point into the latest storage technology.
Addlink G55H: Features and Specifications
The G55H is a DRAM-less PCIe 5.0 NVMe SSD, utilizing Host Memory Buffer (HMB) technology. This means it leverages system memory for primary caching. The drive employs the Phison E31T controller and 218-layer NAND, a portion of which is used for secondary caching via single-bit SLC (Single Level Cell) writing, later transitioning to native three-bit TLC (Triple Level Cell). Addlink backs the G55H with a five-year warranty and a 600TBW (Terabytes Written) rating per 1TB of capacity, indicating its endurance for sustained write operations.

Addlink G55H: Pricing and Availability
At the time of writing, the 1TB G55H is priced at $121.44, while the 2TB version is $221.44 on Amazon. This competitive pricing makes it a compelling option compared to other PCIe 5.0 HMB SSDs like the Corsair MP700 Elite. However, remember that SSD pricing is dynamic, so it’s always wise to compare prices before purchasing.
Addlink G55H: Performance Benchmarks
The G55H delivers impressive performance, ranking among the top NVMe SSDs we’ve tested, including those with dedicated DRAM. While synthetic benchmarks reveal a significant gap between the G55H and DRAM-equipped drives, the real-world performance difference is currently less pronounced.
In CrystalDiskMark 8 sequential tests, the G55H narrowly outperforms competitors like the PNY CS2150 and Corsair MP700 Elite, showcasing its speed potential.

While the G55H performed well in AS SSD benchmarks, contributing to its overall ranking, the performance differences between these three drives are often within the margin of error. It’s crucial to remember that while PCIe 5.0 boasts higher theoretical speeds than PCIe 4.0, the real-world benefits are limited without software optimized for NVMe queues, which is currently rare.
Addlink G55H: Final Verdict
The Addlink G55H is a highly recommended PCIe 5.0 SSD, offering competitive performance and an attractive price point. While current real-world performance gains over PCIe 4.0 are minimal, the G55H is a future-proof investment for those seeking cutting-edge storage technology. If you’re considering a PCIe 5.0 HMB SSD, price should be the primary deciding factor among the current contenders, and the G55H certainly holds its own in that regard.
