Addlink G55 1TB PCIe 5.0 x4 NVMe M.2
The Addlink G55 hits 10,300 MB/s reads and 9,000 MB/s writes over PCIe 5.0, with a TSMC 7nm controller that avoids throttling and a 2.3 mm single-sided build for tight laptop slots. Its DRAM-less design uses Host Memory Buffer to boost random I/O, and the five-year warranty adds peace of mind. Best for gamers, creators, or AI users on Intel 13th-14th Gen or AMD Ryzen 7000-9000 platforms who need top Gen5 speed and will fit a heatsink.

Resumen
The 30-Second Version
10,300 MB/s sequential reads put the G55 in the 95th percentile for speed, and the TSMC 7nm controller keeps it from melting down. Random performance is just average at the 59th percentile, and endurance is nothing special. At $207 USD, it's a great buy if you need raw throughput, less so if you're just gaming.

Performance
Sequential reads of 10,300 MB/s and writes of 9,000 MB/s put this drive in the top tier of our database. That's the 95th percentile for speed, which means it's outpacing nearly everything else we've tested. The TSMC 7nm controller deserves credit here. Gen5 drives have a reputation for running hot and throttling, but the G55 manages to sustain those speeds without turning into a space heater. Random performance is where things get more pedestrian. The 59th percentile ranking means it's solidly average for random reads and writes. The DRAM-less design with HMB support helps, but it's not a magic bullet. For everyday tasks and gaming, you probably won't notice. For heavy sustained random workloads, there are better options.

vs Competition
Against the Samsung 9100 PRO, the G55 holds its own on sequential reads but falls behind on random performance and endurance. The Micron T710 and Crucial T710 both offer better all-around numbers, though they typically cost more. The Lexar NM1090 PRO is a closer match on price, but its thermals aren't as well managed. The WD_BLACK SN7100 trades blows on random performance but can't match the G55's sequential throughput. If you want the fastest sequential reads without paying Samsung prices, the G55 is a compelling option. If you want balanced performance across the board, the T710 twins are worth the extra cash.

Value & Pricing
At $207 USD, the G55 is priced like a mid-range Gen5 drive, and that's exactly where it sits. You're paying for the sequential speed, which is genuinely top-tier. The CAD 303 listing tracks similarly for Canadian buyers. The 5-year warranty adds some peace of mind, but the endurance numbers don't suggest this drive will outlast its competitors. If you need raw throughput for large file transfers or content creation, the price is fair. If you're mostly gaming, you could save money on a Gen4 drive and never notice the difference.

Overview
The Addlink G55 hits 10,300 MB/s sequential reads in our testing, which puts it in the 95th percentile for speed. That's the headline here. This is a Gen5 drive that actually delivers the kind of numbers the spec sheet promises, and it does it without a massive heatsink bolted on. The TSMC 7nm controller keeps things surprisingly cool for a drive this fast. But the rest of the picture is more mixed. Random performance lands at the 59th percentile, which is fine but not exciting. Endurance sits at 56th percentile, capacity at 54th. You're buying this drive for one reason: raw sequential speed. And on that front, it delivers.
Common Questions
Q: Do I need a heatsink for the Addlink G55?
Yes, Addlink recommends a heatsink for optimal performance. The TSMC 7nm controller runs cooler than many Gen5 drives, but sustained sequential writes at 9,000 MB/s will still generate heat. Most motherboards with Gen5 M.2 slots include a heatsink, which should be sufficient.
Q: Is the G55 worth it over a PCIe 4.0 drive for gaming?
Probably not. The G55's sequential speeds are roughly twice as fast as PCIe 4.0 drives, but game load times don't scale with sequential throughput. The random performance lands at the 59th percentile, which is similar to many good Gen4 drives. You'd be paying extra for speed you won't feel in games.
Q: How does the DRAM-less design affect performance?
The G55 uses Host Memory Buffer (HMB) to borrow system RAM for its mapping tables. This works well for most consumer workloads, but sustained random operations can suffer compared to drives with dedicated DRAM. The 59th percentile random performance ranking reflects this trade-off.
Who Should Skip This
Skip this drive if you're building a gaming PC and want to save money. The sequential speed is impressive, but games don't care about 10,300 MB/s reads. Random performance at the 59th percentile means you'll see similar load times from a good Gen4 drive at half the price. Also skip it if you need strong sustained random performance for database work or heavy virtualization. The DRAM-less design and average endurance numbers make this a poor fit for write-heavy server-style workloads.
Verdict
The Addlink G55 is a one-trick pony, but it's a really good trick. Sequential speeds in the 95th percentile at a mid-range price make this an easy recommendation for content creators and anyone moving large files regularly. The DRAM-less design and average random performance keep it from being a universal pick, but for the right workload, this drive is a steal.
