A-Data Ultimate SU800 ASU800SS-1TT-C 1.02 TB

Classic 2.5-inch SSD, designed for users who need a versatile SSD with full caching capabilities and a high rewrite endurance within the SATA III interface. Despite being part of the SATA SSD class, the A-Data Ultimate SU800 is positioned as a more advanced solution compared to basic models of the same format, making it suitable not only for home setups but also for work systems with moderate loads.

This drive is based on 3D QLC NAND memory and is equipped with 1 GB of buffer DRAM memory, which is rare for devices with this type of flash memory. The presence of a dedicated cache ensures consistently high performance when handling a large number of random operations and helps avoid the characteristic speed drops of QLC solutions during long-term writing. This is particularly important for tasks that include installing and running large applications or working with a large number of small files.

Sequential read and write speeds are close to the limits of the SATA III interface, reaching 560 MB/s and 520 MB/s, respectively. Moreover, the declared IOPS of up to 85,000 for reading and up to 80,000 for writing confirm the drive's readiness for multi-threaded operations typical of modern systems. Another significant advantage of the SU800 is its increased rewrite endurance — 800 TBW, which is substantially higher than the average level for models with QLC memory. Ideal for work scenarios where frequent data rewriting is expected.
