The ThinkPad 320 GB 7200 rpm SATA 3.0 Gbps 7 mm 4k hard drive provides a robust thin design enabling a seamless upgrade from the primary hard drive of supported ThinkPad laptops. This provides good storage size, advanced format, SATA data transfer capabilities, and 7200 rpm disk speeds providing almost desktop like performance. The advance format or 4k sector emulates the 512 sector drives while delivering higher capacity points along with improved error correction capabilities, the ultimate benefit of higher HDD density and better yield at a lower cost per gigabyte.
