ADATA vs INLAND SSD Specs
transfer speed
The ADATA SU800 1TB leads in sequential performance with read speeds up to 560 MB/s and write speeds up to 520 MB/s. The INLAND Pro 120GB offers slightly lower figures, with reads up to 520 MB/s and writes up to 410 MB/s. Both drives utilize the SATA III interface, which caps practical throughput. The ADATA model provides a noticeable advantage in sustained write speeds, which helps when moving large files. The INLAND drive remains competitive for general tasks but trails in maximum throughput metrics provided in the specifications.
storage capacity
Capacity is the most distinct difference between these two drives. The ADATA SU800 is available in 1TB and 2TB options, offering substantial space for games, video editing, and large datasets. The INLAND Pro is listed with a 120GB capacity, which is suitable for basic operating system installation and essential applications. While INLAND variations include other sizes like 240GB or 512GB, the specific 120GB model compared here is significantly smaller. If you need to store many files, the ADATA drive is the clear choice for higher density storage.
cache type
The ADATA SU800 includes a DRAM Cache Buffer alongside Dynamic SLC Caching. This hardware cache helps manage data mapping tables, improving performance during heavy random read and write operations. The INLAND Pro specifications mention 3D TLC NAND and sequential speeds but do not list a DRAM cache. Instead, it relies on its NAND type for performance management. The presence of DRAM in the ADATA drive generally provides better sustained performance under load compared to drives without dedicated memory.
nand type
Both drives utilize 3D NAND flash technology, which is a key similarity. This type of NAND stacks memory cells vertically, allowing for higher capacities and better endurance compared to older planar NAND. The INLAND Pro specifically identifies its NAND as 3D TLC, which balances cost and performance. The ADATA SU800 also uses 3D NAND, though the exact cell type (TLC or QLC) is not explicitly detailed in the provided specs. Both technologies offer resistance to shock and vibration, making them suitable for laptops.
form factor
Both the ADATA SU800 and the INLAND Pro use the standard 2.5-inch form factor, ensuring compatibility with most desktops and laptops that support SATA drives. The physical dimensions are nearly identical, with both measuring approximately 2.75 inches in width and 3.95 inches in length. The height is also consistent at 0.28 inches for both models. This standardization means you can swap one for the other in most existing systems without needing additional adapters or mounting hardware.
warranty
Both manufacturers offer a three-year warranty on these specific models. The ADATA SU800 includes a 3 Year Warranty, while the INLAND Pro provides a 3 Year Limited Parts and Labor Warranty. This coverage period is standard for consumer SSDs and provides peace of mind regarding product longevity. There is no significant difference in the warranty duration between the two products. You can expect similar levels of manufacturer support for defects or failures within the first three years of ownership.
Choose the right SSD for your needs
Users needing large storage for files
You should choose the ADATA SU800 if you require significant space. It offers 1TB of capacity, which is far more than the 120GB INLAND model. This larger size allows you to store more documents, photos, and applications without running out of room quickly.
Buyers prioritizing maximum read performance
The ADATA drive delivers faster sequential read speeds up to 560 MB/s. This is higher than the INLAND Pro’s 520 MB/s limit. If you frequently load large files or games, this speed advantage can reduce wait times during data retrieval and application launches.
Shoppers on a tight budget
The INLAND Pro 120GB is a lower-cost entry point. Its 120GB capacity is sufficient for basic operating system installation and essential programs. You get a reliable SATA III connection and 3D NAND technology, making it a practical choice for simple computing tasks.
