About Hardware Seagate Momentus Thin ST320LT012-9WS14C
Seagate ST320LT012-9WS14C is a 320GB capacity hard disk drive (HDD) with a slim 2.5-inch form factor, ideal for laptops, notebooks and other portable systems. Designed using a SATA II (3Gbps) interface and a rotation speed of 5400 RPM, this HDD emphasizes power efficiency and quieter operation compared to higher-speed HDDs.
It uses 1 platter and 2 read/write heads, a common configuration for 320GB capacity, with light weight and low power consumption-suitable for mobile devices. Equipped with 16MB of buffer cache, its performance is sufficient for daily tasks such as saving documents, running light applications, or storing multimedia files.
This Seagate ST320LT012-9WS14C performance test was conducted using an HP 1000 1b05AU laptop that still relies on 4GB DDR3 Single Channel RAM with two DIMM slots. The operating system used during the test was Windows 7 64-bit, which is a typical environment for entry-level laptops in this era of HDD usage. The hardware combination reflects the real usage scenarios of older generation laptop users who still rely on mechanical hard disks as the primary storage medium.
In tests using CrystalDiskMark benchmark software, the Seagate ST320LT012-9WS14C hard disk recorded a fairly stable performance for the 5400 RPM HDD class. The sequential read speed reached 84.67 MB/s, while the sequential write speed stood at 83.84 MB/s. These results show that despite being an older generation HDD with modest specifications, its performance is still adequate for everyday light computing needs such as document storage and media playback.
Although its performance falls short of modern SSDs, the Seagate ST320LT012-9WS14C remains a reliable and cost-effective choice for users who need additional internal storage on older laptops, educational systems, or as external media (with a USB case). Its compact size and low power consumption also make it suitable for use in netbooks and other energy-efficient devices.
