Seagate Mobile HDD 1TB 2.5" 5400RPM SATA 6Gb/s Internal HDD

The Seagate ST1000LM035 is a 1 TB internal hard drive built for people who need dependable storage inside a laptop, all-in-one PC, or compact desktop that uses a 2.5-inch bay. It slips into systems that accept drives with a 7 mm height, so it works naturally in thin notebooks and many external USB enclosures as well.

Because the drive connects through a SATA interface that moves data at up to 6 Gb/s, it pairs easily with modern chipsets and docking stations. A 128 MB cache helps smooth everyday tasks such as booting an operating system, opening large photo libraries, or launching games. The 5400 rpm motor keeps power draw and noise in check, while sustained transfer rates reach about 100 MB/s—enough for streaming high-definition video or running office applications without hiccups.

The platter technology relies on shingled magnetic recording and an advanced 512e format, which lets Seagate fit a full terabyte of capacity into the slim enclosure. Built-in shock resistance up to 400 g during operation, plus an estimated 600,000 load and unload cycles, means the drive can handle the bumps and jolts that come with travel or daily commuting.

Whether you are refreshing an older laptop, adding bulk storage to a mini-PC, or assembling a lightweight external backup drive for photos and media, this model delivers a balance of capacity, efficiency, and quiet running. A two-year limited warranty from Seagate adds extra peace of mind.
