About Hardware TOSHIBA MK3252GSX
The TOSHIBA MK3252GSX is a chunky 2.5-inch hard disk with a 320GB capacity, specifically designed for use in laptops and other mobile devices. Using a SATA II (3.0 Gbps) interface and operating at a rotational speed of 5400 RPM, this HDD offers a balance between power efficiency and basic performance, making it an ideal solution for everyday use.
Equipped with 8MB of buffer cache, the drive is capable enough to handle common storage needs such as operating system files, work documents, music collections, and medium-resolution videos. Although it cannot match the speed of a solid-state drive (SSD), the TOSHIBA MK3252GSX remains an affordable alternative for users who prioritize storage capacity at a more economical price.
Physically, this hard disk generally uses two platters and four heads to read and write data, a standard configuration for a 320GB HDD. In synthetic testing, the read and sequential speed was 41.22 MB/s and the write speed was 38.74 MB/s, depending on system conditions and data fragmentation.
Despite the growing popularity of SSDs, the TOSHIBA MK3252GSX remains relevant as a backup storage solution or as a cost-effective upgrade for older laptops that still rely on mechanical storage media. Its ample capacity and power efficiency make it suitable for use in educational systems, netbooks or home computers with light to medium storage requirements.
