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.

About 80Mbps average write speed backing up to capacity with HD video projects. Started out at around 270Mbps but that only lasted the 1st 20 sec or so. I get closer to 100Mbps average throughout with 7200 rpm Seagate laptop drives of same form factor and size. eSata might be a better bet and you won't need an enclosure... no circuitry is exposed as is. **Q: Does it come with software to transfer from a bigger hd to a smaller hd?** A: Use Macrium Reflect free, download it. Its to copy everything from your old HD to your new SSD. It will help you tranfer from bigger to smaller and vice versa. **Q: what country is it made ?** A: Taiwan ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by P***N on September 4, 2020* ### ⭐⭐⭐⭐⭐ Review *by C***Y on November 16, 2019* ### ⭐⭐⭐⭐⭐ Review *by B***Y on September 19, 2024* ## Frequently Bought Together - SP 512GB SSD 3D NAND A55 SLC Cache Performance Boost SATA III 2.5" 7mm (0.28") Internal Solid State Drive (SP512GBSS3A55S25) - SP 1TB SSD 3D NAND A55 SLC Cache Performance Boost SATA III 2.5" 7mm (0.28") Internal Solid State Drive (SP001TBSS3A55S25) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/58478089-silicon-power-256gb-ssd-3d-nand-a55-slc-cache-performance](https://www.desertcart.vu/products/58478089-silicon-power-256gb-ssd-3d-nand-a55-slc-cache-performance) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-03*
