P21 vs S85 Spec Comparison
Transfer Speed
The Addlink P21 offers sequential read speeds up to 2,000MB/s via its USB 3.2 Gen 2x2 interface. This is fast for an external drive, allowing you to move large video files or game libraries quickly. In contrast, the Addlink S85 reaches much higher sequential read speeds of up to 6,000MB/s. It also provides sequential write speeds up to 5,400MB/s. This significant speed difference makes the S85 better for heavy data transfers. The P21 is sufficient for general external storage needs, but the S85 delivers superior raw throughput for internal tasks.
Form Factor
You need to consider how you will install or carry the drive. The Addlink P21 is a portable external SSD. It features a sleek aluminum design that weighs just 60g. It is thin at 0.47 inches and includes a USB-C connection for plug-and-play use with laptops, consoles, and phones. The Addlink S85 is an internal M.2 2280 NVMe SSD. It is ultra-slim at 2.25mm high. It fits inside desktops, laptops, and mini PCs with a PCIe 4.0 slot. You cannot use the S85 as a portable external drive without an enclosure, while the P21 is ready to use out of the box.
Cache Type
The internal architecture affects how each drive handles data during intense workloads. The Addlink S85 uses a DRAM-less architecture with Host Memory Buffer (HMB) technology. This design delivers strong Gen4 performance while maintaining low power draw, which is friendly to gaming laptop battery life. The data for the Addlink P21 does not specify its cache type or memory architecture. We only know it uses a USB interface to connect to your host device. Without explicit details on the P21's internal caching, the S85 provides more transparency regarding its performance optimization strategy.
NAND Type
The type of flash memory impacts longevity and consistency. The Addlink S85 explicitly uses 3D TLC NAND flash. This is a reliable choice for everyday computing, gaming, and content creation. It supports NVMe 1.4 for modern efficiency. The provided specifications for the Addlink P21 do not list the NAND type. It only mentions shock-resistant metal casing and cooling fins. Because the S85 clearly states it uses 3D TLC NAND, it has the advantage in transparency regarding its core storage components. You know exactly what technology is inside the S85.
Cooling
Thermal management is important for sustained performance. The Addlink P21 features a metal casing with cooling fins. This design helps keep your data safe and cool under pressure, which is useful for an external drive that may be handled frequently. The Addlink S85 is an internal drive that relies on the airflow within your computer case. The data does not mention specific cooling fins for the S85, though it notes backward compatibility with PCIe 3.0 which may generate less heat. For standalone thermal management, the P21's built-in aluminum body with fins offers a clear structural advantage.
Compatibility
Both drives support a wide range of devices, but in different ways. The Addlink P21 is universally compatible via USB-C. It works with iPhones, laptops, PS5, Xbox, Windows, macOS, and Android. This makes it a versatile backup or expansion drive for mobile creators. The Addlink S85 is compatible with any device having a PCIe 4.0 slot. It is also backward compatible with PCIe 3.0 slots, though it will run at Gen3 speeds. It fits thin laptops, desktops, and mini PCs. The P21 wins for plug-and-play versatility across non-computer devices.

You can easily slip it into your pocket for backups on the go or use it with compatible phones and consoles.
Gamers expanding PS5 storage
The Addlink P21 supports plug-and-play connectivity with the PlayStation 5. Its USB-C interface allows you to store and play games directly from the drive. While the S85 is faster internally, the P21 provides a convenient external solution for expanding your console's library. The shock-resistant metal casing helps keep your data safe. You get up to 2000MB/s read speeds for quick game loading sessions.
Creators seeking internal speed
The Addlink S85 uses Host Memory Buffer technology to deliver strong Gen4 performance. Its sequential write speeds reach 5400MB/s, which is roughly ten times faster than SATA SSDs. This speed helps with rapid large-file transfers for content creation. The 3D TLC NAND flash ensures dependable performance for demanding tasks. You benefit from low power draw, which is friendly to gaming laptop battery life during intensive work.
