Verbatim 2.5'' SATA III 7 mm SSD drives can restore the performance of your system. With the latest 3D NAND technology, they offer the perfect solution for upgrading from a hard drive or older SSD. The Vi550 has a superior controller that allows more reliability, higher capacities and faster read and write speeds. Revitalize an older system by replacing a tired hard drive or an older 2D NAND SSD with a Vi550 S3 SSD. The Vi550 offers read speeds of up to 560 MB/s, up to 20 times faster than a standard hard drive. With an MTBF (mean time before first failure) rating of 2 million hours and a TBW rating of up to 75 TB, the Vi550 is a high quality SSD you can rely on. Professional installation recommended. The highspeed 3D NAND flash chips improve the response time of your system. From faster startup, faster shutdown and faster load times to smooth multitasking, you'll benefit from increased productivity. Verbatim SSDs have no sensitive components with moving parts, so unlike conventional hard drives, they are shock resistant. Because Verbatim's SSDs are quieter than hard drives and produce less heat, your laptop will run longer on a single charge.
