Specs: ADATA SU800 vs Addlink S20
Transfer speed
The ADATA SU800 1TB offers higher sequential performance than the Addlink S20 512GB. ADATA reaches up to 560 MB/s for reads and 520 MB/s for writes. Addlink tops out at 500 MB/s read and 450 MB/s write. Both speeds are typical for SATA III drives. You will notice the difference during large file transfers. The ADATA drive handles sustained workloads better due to its higher limits. This makes it a stronger choice if you move big files often. The Addlink speeds are sufficient for general booting and app launching. However, the ADATA numbers are clearly superior on paper.
Cache type
Caching technology affects how the drive handles data when the main memory is full. The ADATA SU800 uses a DRAM cache buffer alongside Dynamic SLC Caching. This dedicated memory helps manage data mapping more efficiently. The Addlink S20 relies only on built-in SLC write caching. It lacks a dedicated DRAM chip. DRAM caches generally provide more consistent performance under heavy loads. Without it, the drive may slow down when writing large amounts of data. For users who do not constantly write massive files, the difference might be subtle. However, the DRAM buffer in the ADATA drive is a technical advantage for stability.
Storage capacity
You are comparing a 1TB model from ADATA against a 512GB model from Addlink. The ADATA SU800 offers double the storage space. This allows you to store more games, videos, and documents. The Addlink S20 is available in a 512GB size, which is adequate for many users. However, the ADATA brand also offers a 2TB option in its lineup. If you need more room, the ADATA SU800 1TB is the larger option here. The Addlink S20 is limited to 512GB in this specific comparison. For maximum storage, the ADATA drive wins by a significant margin.
Form factor
Both drives use the standard 2.5-inch form factor. This means they fit in the same drive bays in laptops and desktops. The physical dimensions are nearly identical. The ADATA SU800 measures 3.95 inches in length, 2.75 inches in width, and 0.28 inches in height. The Addlink S20 measures 3.94 inches in length, 2.75 inches in width, and 0.28 inches in height. The height difference is negligible. Both are compatible with standard SATA connections. You can swap them in most systems without adapters. This aspect is a complete tie for compatibility and physical fit.
NAND type
Both SSDs utilize 3D NAND technology. This type of memory stacks memory cells vertically to increase density and improve efficiency. It is a modern standard for both drives. The ADATA SU800 explicitly lists its use of new generation 3D NAND. The Addlink S20 also confirms its use of durable 3D NAND design. There is no distinction in the type of NAND used. Both products rely on this same foundational technology. This means you get similar benefits in terms of power efficiency and endurance from the flash memory itself. Neither drive has an advantage here.
Which SSD fits your specific needs
Users needing maximum storage capacity
The ADATA SU800 offers a 1TB capacity, which is double the 512GB available on the Addlink S20. If you store large media libraries or extensive game collections, the larger drive provides more room for your files without requiring immediate upgrades.
Buyers prioritizing top sequential speeds
The ADATA SU800 delivers faster read and write speeds of 560 MB/s and 520 MB/s, respectively. These figures exceed the Addlink S20's 500 MB/s read and 450 MB/s write limits. You will see quicker file transfers and slightly faster application loading times with the ADATA drive.
PS4 owners seeking direct compatibility
The Addlink S20 is explicitly designed for PlayStation 4 consoles. Its 7mm slim form factor fits directly into PS4, PS4 Slim, and PS4 Pro slots without needing extra adapters. You can clone your existing drive and play immediately, making it a hassle-free upgrade for console gamers.
Shoppers wanting DRAM cache support
The ADATA SU800 includes a dedicated DRAM cache buffer alongside dynamic SLC caching. This hardware component helps manage data mapping more efficiently than the Addlink S20, which relies solely on SLC caching. If you prefer traditional cache architecture for consistent performance, the ADATA drive is the better technical choice.
