Kingston A400 480GB SATA SSD

The Kingston A400 480GB is the ultimate budget SATA SSD, offering the cheapest path to solid-state storage for aging systems that desperately need a performance boost. At approximately $28 for 480GB, it is the most affordable SSD from a major brand, making it the top recommendation for breathing life into old laptops and desktops still running mechanical hard drives. Sequential reads reach 500 MB/s and writes hit 450 MB/s, which is below the SATA III maximum but still represents a transformative improvement over any HDD. The DRAMless TLC design keeps costs minimal, and while sustained write performance suffers compared to premium SATA drives, the typical usage pattern of boot, application launch, and file access sees dramatic improvements. The 2.5-inch form factor with included 7mm to 9.5mm adapter fits virtually any system. Kingston's three-year warranty covers the basics. For anyone upgrading an HDD-based system with the smallest possible budget, the A400 provides the most impactful single upgrade available, turning sluggish old computers into responsive daily drivers for a trivial investment.
