About Hardware Seagate Momentus ST950032-5AS
The Seagate ST9500325AS is a 500GB hard disk drive (HDD) with a 2.5-inch form factor, designed specifically for laptops, notebooks and portable devices. Utilizing a SATA II interface (3.0 Gbps) and a rotation speed of 5400 RPM, this hard drive offers a combination of low power consumption and sufficient performance for everyday computing needs, such as document storage, media, and light operating system installations.
Equipped with 8MB of buffer cache, the Seagate ST9500325AS is capable of handling basic read/write activities steadily, though not as fast as modern solid-state drives (SSDs). Nevertheless, it remains a popular choice for budget-conscious systems, secondary data storage, or upgrading storage capacity without high costs. Compared to 7200 RPM HDDs, 5400 RPM models like these also generate less heat and noise, making them suitable for laptops that prioritize comfort and power efficiency.
Technically, this HDD has an average seek time of about 12ms and is designed to support daily workloads with a high level of reliability. In our data transfer speed benchmark tests, the Seagate ST9500325AS performed as follows:
- Read Speed (Sequential Read): ~58 MB/s
- Write Speed (Sequential Write): ~62 MB/s
While its performance is far below that of SSDs, it is still relevant for basic use, especially on older systems or when large capacity is more important than speed. The Seagate ST9500325AS is also commonly found as built-in storage on previous generation laptops, and is still widely used for backups, large media file storage, and as a portable storage solution with external enclosures.

About Hardware Lexar JumpDrive V100 32GB
The Lexar JumpDrive V100 32GB is a portable storage solution designed to provide an optimal combination of speed, reliability and affordability. With a 32GB capacity, this flash drive is perfect for storing important documents, photos, videos, and lightweight presentation files and installers, making it an ideal choice for students, office employees, and casual users.
Using a USB 3.0 interface, the Lexar V100 is able to provide better read and write speeds than traditional USB 2.0 flash drives. While it still supports backward compatibility with USB 2.0 ports, using it on a USB 3.1 Gen 1 port will maximize its performance. Its compact and lightweight design makes it easy to carry around, while its cap cover helps keep the USB connector protected from dust and damage.
This flash drive speed test was conducted using a Lenovo IdeaPad Slim 3i 14ITL6 device, powered by an Intel Core i5-1135G7 processor, supported with 12GB DDR4 dual channel RAM, and running Windows 11 version 22H2 operating system. The combination of these specifications provides a stable and representative testing environment to assess the actual performance of the flash drive under test.
In tests using the CrystalDiskMark application, the flash drive was able to record read speeds of up to 143.53 MB/s, while write speeds reached 34.33 MB/s. These results reflect quite good performance for daily use such as moving documents, images, or medium-sized media files.
Meanwhile, through additional testing using ATTO Disk Benchmark with a block size of 64MB, the flash drive showed a read speed of 140.66 MB/s and a write speed of 25.04 MB/s. Slightly lower write performance in ATTO compared to CrystalDiskMark is common, as the test methods used by each benchmark can produce varying results depending on the type of data and block size used.
Overall, this flash drive offers a fairly high read performance for its class, although the write speed is moderate. For users looking for a portable storage solution for daily data transfer purposes, this flash drive remains reliable with consistent performance across various scenarios.
The read speed of close to 140MB/s shows that this flash drive is responsive enough for activities such as opening large files or playing videos directly from USB. However, the lower write speed (below 40MB/s) reflects the reasonable limitations of economy-class flash drives without DRAM cache.
Technically, the Lexar V100 uses the PF619-32AR NAND chip and ZC3281 controller, a common configuration for low-cost and power-efficient flash drives. Although TBW (Total Bytes Written) and DRAM cache specifications are not available, Lexar remains a trusted brand in the digital storage world, with a good reputation for manufacturing quality and system compatibility.
With a simple design, decent read speed, and competitive price, the Lexar JumpDrive V100 32GB is one of the best choices for users who need a cheap and reliable USB 3.0 flash drive for daily use.
