The SU800 solid state drive lives up to its Ultimate name with 3D NAND Flash that provides higher storage density, efficiency, and reliability than traditional 2D NAND. It features intelligent SLC caching and a DRAM cache buffer to boost read/write performance even further. Featuring LDPC ECC and technologies such as high TBW (total bytes written) and DEVSLP (Device Sleep), the Ultimate SU800 instantly upgrades notebook and desktop PCs with superior stability, durability, and power efficiency. In addition, users can download ADATA in-house developed SSD Toolbox and Migration Utility software for free to enjoy easy data management and migration.

New generation 3D NAND Flash

Implementing advanced 3D NAND Flash, the Ultimate SU800 features bigger storage capacities, higher efficiency, and rugged reliability with better cost-performance ratios than ever. The Ultimate SU800 reaches read/write speeds of 560MB/s and 520MB/s to accelerate PCs.

Wide Capacity Range And High TBW

Thanks to the flexibility of 3D NAND, we can offer the Ultimate SU800 in diverse capacities, ranging from 128GB to 1TB. You get more choice for different needs, whether for an OS boot drive or a mass storage drive. All Ultimate SU800 models provide high TBW (Total Bytes Written), meaning the number of times an SSD can write its entire capacity in one lifespan. The Ultimate SU800’s TBW rating outranks comparable models, indicating a longer-lasting SSD.

Intelligent SLC Caching and DRAM Cache Buffer

The intelligent SLC caching algorithm allows NAND Flash memory to operate in single-level cell mode and boosts read/write performance. In addition, with the support of DRAM Cache Buffer, read/write performance can be as much as double that of solid state drives that lack a DRAM cache, or in other words that can't use system memory as an SSD buffer for high intensity tasks.

Advanced LDPC ECC Engine

Low density parity check error correcting code has been implemented on the Ultimate SU800, leading to a massive reduction in data errors and an equal increase in data integrity. It therefore protects your valuable content against corruption to a much greater extent than non-ECC SSDs or even SSDs that use basic BCH error correction.

RAID Engine and Data Shaping for Ultimate Protection

By supporting RAID Engine and Data Shaping, the Ultimate SU800 ensures data integrity and delivers extended SSD lifespan for better, longer-lasting stability and return on investment.

Outperforms HDDs with Massive Performance Gain

Utilizing high quality materials and advanced technologies, the Ultimate SU800 outperforms traditional HDDs by a huge factor, with particular benefits in boot up and seek time, as well as overall much faster read/write throughput.

Lower Power Consumption, Longer Battery Life

The Ultimate SU800 supports DEVSLP (Device Sleep) technology for better energy efficiency. This results in lower electricity costs and prolonged battery life. Compared to traditional HDDs, the Ultimate SU800 consumes just 8% of the power while in idle mode, and 80% less power during regular operation. For users who often travel or go on business trips, the Ultimate SU800 is a great partner with high mobility and power-saving abilities that go easy on notebook batteries.

Proprietary Software - SSD Toolbox and Migration Utility

Every Ultimate SU800 purchase qualifies for free downloads of ADATA SSD Toolbox and Migration Utility. SSD Toolbox allows users to monitor and manage the Ultimate SU800, with drive status, wear level, and lifespan information. Data migration utilities are especially helpful for users making the move from HDD to SSD, as they are designed for simple and quick backup and migration of the contents of entire drives, including the operating system.

For Notebooks and Desktops

Just 7mm thick, the Ultimate SU800 is an easy fit in ultrabooks. A 2.5mm spacer is bundled for use in 9.5mm disk bays, allowing compatibility with virtually every notebook and desktop.

Bought to replace my girlfriend's HDD in her laptop as I could see it was slow and its works as expected

Does exactly what it's supposed to and transformed the speed and usability of some old computers for very little money. Used the excellent free Mini tool Partition Wizard free to clone the old hard disk. Worked first time.

Very good communication, I am very satisfied by the product, definitely buy more products and recommend others to buy from ccl with confidence.


October 2019

Very fast ssd, arrived promptly and was quite easy to clone my hard drive by using acronis true image. After installation, I can clearly see the speed boost while booting up windows 10 and all my applications run very fast now. Will definitely recommend this product to anyone looking to upgrade their old laptop / desktop to an SSD.

Obviously early days fora solid state drive but so far it has supported my efforts at rebuilding a PC with W10 as an OS with the end of W7 on the horizon. Had a bit of trouble trying to update the firmware but seems to be working fine with a ten year old motherboard.Quite good GB for your buck!
