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.

About Hardware HGST HTS545050A7E680
The HGST HTS545050A7E680 is a 500GB hard disk drive (HDD) designed for storage needs in laptops, external enclosures, and other mobile devices. With a 2.5-inch form factor, 5400 RPM rotation speed, and 3.0Gbps SATA II interface, this HDD offers an ideal blend of capacity, power efficiency, and stable and quiet performance for everyday computing needs.
Based on the Travelstar Z5K500 family, this HDD uses 1 platter and 2 heads, which structurally supports reasonably efficient performance without generating excess heat or noise. The 8MB buffer cache provides a speed boost in short data processing, which is especially useful for light activities such as opening document files, playing videos, and storing business application data.
In tests using a USB 3.0 HDD enclosure connected to a Lenovo IdeaPad Slim 3i 14ITL6 laptop (with Intel Core i5-1135G7 processor and 12GB DDR4 dual-channel RAM), the drive recorded CrystalDiskMark scores of 108.05 MB/s read and 104.88 MB/s write speeds. Meanwhile, the ATTO Disk Benchmark (64M) test showed read performance of 102.40 MB/s and write performance of 101.45 MB/s - relatively good results for a 5400 RPM HDD in an external configuration.
While not an SSD, the HGST HTS545050A7E680 still offers high reliability and low power consumption, making it a suitable solution for users who need additional storage or an affordable replacement for an internal HDD while still prioritizing long-term stability. In addition, HGST's shock resistance feature provides extra protection against minor physical impacts that often occur on mobile devices.
Overall, the HGST HTS545050A7E680 is a great choice for laptop users, light content creators or business users who require medium capacity, low power consumption and reliable performance in a portable or internal drive.
