ST2000LM015 – 2TB Seagate BarraCuda 2.5-Inch Hard Drive for Laptops and Portable Devices
The Seagate ST2000LM015 is a 2TB BarraCuda 2.5-inch mechanical drive designed for laptop upgrades, external enclosures, and portable storage builds where high capacity is needed in a slim 7mm form factor. It suits resellers and system integrators serving consumer repair, refurbishment, and entry-level storage channels rather than NAS, surveillance, or enterprise workloads — those segments are covered by Seagate’s IronWolf, SkyHawk, and Exos families respectively. Note that as a 5400 RPM mechanical drive it trades throughput and latency for capacity and cost per gigabyte, so it is not a drop-in substitute for an SSD in performance-sensitive applications.

Good to know
- Verify host bay height before ordering: the 7mm profile suits most current laptops and slim external enclosures, but some older 9.5mm bays will accept it with minor clearance slack.
- Within the BarraCuda family this sits at the consumer portability end; for always-on multi-bay NAS, 24/7 surveillance DVRs, or data-center arrays, Seagate’s IronWolf, SkyHawk, and Exos lines are the workload-matched alternatives.
- Confirm regional power adapters and SATA cabling requirements with your integration checklist, and request current stock lead times and applicable warranty terms from your account manager, as these vary by batch and destination market.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
