Seagate 1TB 7mm laptop drive

This Seagate Mobile HDD delivers 1TB of storage in a 7mm thin 2.5 inch form factor. It uses a standard SATA 6Gb/s interface and includes 128MB cache. The drive is built new for laptops, convertibles and other slim devices where space and weight are constrained. It stores up to 200000 photos, 250000 songs or 124 hours of high-definition video.

Check laptop bay height and interface

Verify that your device accepts a 7mm high 2.5 inch SATA drive before ordering. Some ultra-thin chassis only fit thinner modules or require a different connector. Confirm the system uses a SATA interface and has a free drive bay or caddy. Retail or OEM packing may vary, so mounting hardware might not be included.

Upgrade from lower-capacity laptop HDD

This drive replaces smaller 2.5 inch laptop hard drives when you need more space without adding bulk. The jump is worth it if your current drive is full and the system supports the 7mm height. It enables a drop-in capacity transition up to 2TB without the weight of traditional laptop drives. Buyers needing solid-state speed or drives thicker than 7mm should look elsewhere.

Questions about this item

Does the Seagate ST1000LM035 come with mounting screws or a SATA cable, or must I buy those separately?

The drive is supplied as a bare 2.5 inch unit only; mounting screws and a SATA data cable are not included and must be sourced separately.

Should I choose the 1TB ST1000LM035 or the larger 2TB model for my laptop upgrade?

Both use the same 7mm thin form factor and SATA 6Gb/s interface; pick the 2TB version if you need space for roughly 200000 extra photos or 124 more hours of high-definition video, otherwise the 1TB model saves cost.

What does the 128MB cache actually do for everyday laptop use?

The 128MB cache buffers frequent read and write requests, which helps the drive serve small files faster and keeps the system responsive during multitasking.
