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. 3-year Warranty The Ace A55 is backed by 3-year warranty. *Please register your product via SP official website to get the complete manufacturer warranty services, product support and more.

It's a standard 2.5" SATA drive, just like the listing says, and will work with nearly all desktop and laptop PCs (even Apple) that have a 2.5" or 3.5" SATA interface, which would be nearly all of them except for the very newest and slimmest laptops that no longer have a 2.5" bay. **Q: Will this work for my for my asus q 302l** A: Likely will work. Just remember, most newer SSDs are 7mm thick. If you are putting this in an older unit that had a 9mm thick drive then you will need the extra SSD spacer (usually foam or rubber material) to make up the difference to eliminate any possible motion with the extra empty space in the drive bay. Have had many repairs come in for this very reason with the SSD connectors broken due to motion within the drive bay. **Q: Can this ssd drive be used to replace a toshiba mk2555gsxf drive?** A: Likely will work.
