## Description

From the manufacturer 3D NAND Technology for Enhanced Reliability and Power Efficiency Applying the advanced 3D NAND flash, Ace A55 features higher reliability and better power efficiency than traditional SSDs equipped with 2D NAND flash. The A55 offers improved endurance and longer battery life that you're able to work longer without frequently recharge your laptop. High Transfer Speeds for Fast Start Up Powered by high quality controller and original synchronous NAND flash, the A55 delivers incredibly high transfer speeds that enable short boot time, fast application loading and quick file processing. SLC Cache Technology for Performance Boost and Longer Lifespan The A55 especially applies the ”SLC Cache technology” that allows all data to be written in the SLC portion first and leads to higher peak writing performance. In addition, the technology can reduce write amplification and thus offer better endurance and longer lifespan of the SSD. Free-download SSD Health Monitor Tool - SP Toolbox Software The A55 comes with a free-download SSD health monitor tool - SP Toolbox Software, which is especially designed for you to easily monitor the current health status of a SSD. By such, you can run a performance test, get an overall health evaluation and check detailed information about your SSD, including used space on device, device temperature, total bytes written, S.M.A.R.T. status, erase count status and block numbers. *Please download the software at SP Official Website. Absolutely Reliable with Bad Block Management The A55 is built with Bad Block Management, which can continually monitor and replace bad blocks to keep your system in good condition with prolonged lifespan of a SSD. Multiple Techniques Supported The A55 is one of the lightest and thinnest SSD of its kind yet it is shock- and vibration-proof since it contains no moving parts. Furthermore, S.M.A.R.T. monitoring system and ECC technology are equipped to promise higher data transmission safety.
