About Hardware Hitachi HTS547550A9E384

The Hitachi HTS547550A9E384 is a 500GB 2.5-inch hard disk drive (HDD) designed for laptops, notebooks and portable devices. This HDD belongs to the Travelstar 5K750 line, which is known for its balance between performance, power efficiency and reliability.

Using a 3.0Gbps SATA-II interface and a rotation speed of 5400 RPM, the drive offers good enough performance for daily computing activities such as document storage, multimedia playback, and light operating system installation. Equipped with an 8MB buffer cache, this hard drive provides a stable usage experience, though not as fast as a 7200 RPM HDD.

The Hitachi HTS547550A9E384 comes with a 500GB capacity, enough to store thousands of documents, photos, and multimedia files on a single device. This hard disk uses a 2.5-inch form factor with a SATA-II (3.0Gbps) interface, which is still widely used in older generation laptops. The spinning speed is 5400 RPM, which is not as fast as a 7200 RPM HDD, but it is more power-efficient and quieter in operation.

Underneath the body, this HDD has an 8MB buffer (cache), and consists of two platters and three data-reading heads. The drive is part of the Travelstar 5K750 line, which is known for its durability and efficiency for everyday use, especially in portable devices or laptops with limited power.

To determine its performance, the drive was tested using an HP 1000 1b05au laptop powered by an AMD E1-1200 processor, with a 2x2GB DDR3 1066MHz RAM configuration in single channel mode due to limited dual channel support on the CPU. The drive is mounted via HDD Caddy on the DVD slot and runs Windows 7 operating system.

In tests using CrystalDiskMark, the HDD recorded a read speed of 88.66 MB/s and a write speed of 88.06 MB/s. These results reflect the typical performance of a 5400 RPM HDD with a SATA-II interface, sufficient for standard use such as light booting, file storage, and basic applications.

That's consistent performance with 5400RPM HDDs of this generation and interface. While these drives don't rival SSDs in terms of speed, they are still an ideal power-saving storage solution for devices with battery limitations or legacy devices that still rely on mechanical storage.

Device test (testbed):

Device: HP 1000 1b05au (using HDD Caddy on DVD Slot)
Specs: 
CPU: AMD E1-1200
OS: Windows 7
RAM: 2x2GB Single Channel 2 DIMM 1066MHz (Does not support dual channel due to limitations of the CPU, currently running single channel mode and 1066MHz)
