ADATA SD810 vs SE880: Which External SSD Is Better
If you’re deciding between the ADATA SD810 and SE880, it helps to look beyond the specs. Both drives offer fast USB 3.2 performance and portability, but they differ in sustained speeds, durability, and size. In this comparison, we’ll break down the key differences so you can choose the SSD that best fits your needs.
Performance & Durability
ADATA SD810
- Pros:
- Robust USB 3.2 Gen 2×2 (20 Gbps) performance and competitively priced, especially in larger capacities like 4 TB.
- Durable titanium exterior with IP68 dust/water resistance (with cap on), and 5-year warranty.
- Often outperforms other 20 Gbps SSDs in real-world benchmarks.
- Cons:
- Sustained write speeds drop sharply after the SLC cache is filled—down to ~230–250 MB/s, which may impact large file transfers.
ADATA SE880
- Pros:
- Ultra-compact and lightweight—smaller even than many thumb drives, making it extremely pocketable.
- Delivers respectable USB 3.2 Gen 2×2 performance initially.
- Cons:
- Lacks dust/water protection and doesn’t have a cap for the port.
- Suffers a steeper drop in sustained write speeds—down to around 70 MB/s—after the cache is used up, which is notably slower than the SD810’s fallback speeds.
