Tsh 175,000

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 2TB. 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.

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.
