ADATA Ultimate SU800 256GB SSD Review


ADATA’s Ultimate SU800 is meant to be a low-cost mainstream drive that delivers great performance. ADATA’s decided to use new SM2258G 4-channel controller, which combine with SLC caching translate into better overall performance. As you can see the SU800 256 GB performed as expected to give 562MB/s read and 503MB/s writes in the test, which is same as ADATA claimed 550MB/s read and 500MB/s write so there no complaints here. Though, ADATA didn’t include any AES 256-bit hardware-based encryption. Like all other SLC caching drive the ADATA Ultimate SU800 also not great for a large amount of data transfer at a time, after the SLC buffer was full and data was being written directly to the 3D TLC NAND Flash you will face a significant drop in speeds. Also, TLC NAND has less writing endurance compared to SLC or MLC NAND. ADATA provides a 3year warranty on the SU800 series. The Ultimate SU800 is designed to use in the entry-level system who want to update from a traditional 5400 RPM or 7200 RPM hard drive for the standard work environment or gaming.

ADATA Ultimate SU800 256GB SSD ReviewOverall ADATA Ultimate SU800 performed as expected and there nothing wrong with it, the pricing also very reasonable with this 256GB coming in just $79.99 US / ₹6000 in India. The support of the LDPC Error Correction Code (ECC), data shaping for endurance and longevity and RAID engine support makes this a great package in terms of reliability and long life. Though the Ultimate SU800 is a great option for the budget   segment, but it’s not for everyone, as the drive didn’t have built-in AES 256-bit hardware encryption and the TLC NAND limitation of performance drops here and there when writing an enormous amount of data, means the Ultimate SU800 will not suit professionals and heavy users. Still, we can’t blame it as ADATA Ultimate SU800 not meant for that kind of usage. But an average user didn’t write that much as they read out of the drive and for that aspect ADATA Ultimate SU800 is a great performer, and we are giving it GOLD AWARD.
