Adata vs. Samsung SSD – How do they compare?

Flash memory and controller

Since 2016, Adata has been using 3D TLC NAND flash memory and Silicon Motion controller in its external SSDs. Similarly, the Adata Ultimate SU800 features the Micron 3D TLC NAND memory, a high-density memory that is less expensive to manufacture than the traditional multi-layer cell (MLC). This drive’s memory stacks its memory vertically, giving the drive a higher endurance rating than that of the more conventional non-3D TLC memory. It also uses the SM2258 controller, which was specifically built for use with its flash memory. As such, the flash memory and controller of this drive provide the perfect blend of endurance, price, and performance.

On the other hand, Samsung has its own line of flash memory and controller it uses for its external SSDs. As such, the Samsung 860 EVO uses its own 64-bit V-NAND, which is 30%more energy efficient and 1.5 times than its predecessor, the 48-bit V-NAND flash memory. Similar to the Adata Ultimate SU800 memory, this memory also stacks its flash cells vertically and in 3D for higher speed and density. The drive also utilizes Samsung’s MJX SATA controller for increased power efficiency and speedy performance.

Samsung 860 EVO is, therefore, equipped with a better performing memory and controller than the Adata Ultimate SU800, as it increases the drive’s power efficiency and overall performance.

Design and storage space

Adata is known to deliver compact and premium quality SSDs in multiple capacity points. The Adata Ultimate SU800 is a 7mm (2.5-inch) thick drive that comes with a license key for Acronis True Image HD-drive migration software and a 2mm spacer for laptops with a 7.5-9.5mm-high drive bays. The drive is available in four standard mainstream capacity points of 128GB, 256GB, 512GB, and 1TB. Each of these drives features an impressive price to capacity ratio.

Alternatively, Samsung produces portable external SSDs with a simple design. As such, the Samsung 860 EVO is a 2.5-inch drive with a black enclosure and light grey square at the top of the Samsung branding. On the flip side, the drive contains a large sticker with all the essential information about the drive, such as serial number, capacity, and model. This drive is available in five sizes, including the 4TB, 2TB, 1TB, 500GB, and 250GB.

Samsung 860 EVO offers more storage capacity than the Adata Ultimate SU800.

Performance

Both Samsung and Adata SSDs feature impressive speeds that facilitate increased performance of desktops, PCs, and laptops. Adata’s Ultimate SU800 features an impressive DRAM memory cache as well as a built-in intelligent SLC caching that boosts the drive’s sequential read and write speed to a maximum of 560Mbps and 520Mbps, respectively. Its read/write performance is five times faster than the traditional HDD, making simple tasks, like starting up your desktop or laptop, run quicker and more efficiently. The drive also consists of RAID engine and Data Shaping that enhances overall data protection and drive stability. It also has in-built software, such as DEVSLP and high TBW, that will instantly improve the performance of your device as it enhances its durability, performance and ensures effective power management.

Samsung’s 860 EVO features consistent speeds even when multi-tasking or under heavy workloads, ensuring fast and efficient file transfer. The drive has an impressive sequential read and write speed of 550Mbps and 520Mbps, respectively, with the help of its Intelligent TurboWrite technology. It also has eight times higher endurance rating than the 850 EVO, making it more secure for rendering and storing large files and data.

The Adata Ultimate SU800 is, therefore, slightly faster than the Samsung 860 EVO, with a sequential read and write speed of up to 560/520Mbps.
