Seagate ST4000LM024 – 4TB 2.5-Inch SATA Hard Drive
The Seagate ST4000LM024 is a 4TB 2.5-inch SATA hard drive built for capacity-constrained deployments where a 3.5-inch drive will not fit — portable NAS enclosures, compact external storage arrays, mobile workstations, and embedded systems. Its 5400 RPM spindle and low power draw suit sequential workloads and battery-powered applications rather than high-IOPS duties, which remain the domain of SSDs. Note the 15mm height: buyers should confirm their chassis or drive bay supports this thicker profile before ordering.
Key specifications (table)
| Parameter | Specification |
|---|---|
| Model | ST4000LM024 |
| Brand | Seagate |
| Capacity | 4TB (4000GB) |
| Form Factor | 2.5-inch, 15mm height (thicker than standard 7mm/9.5mm laptop bays — verify bay clearance) |
| Interface | SATA 6 Gb/s (backwards compatible with SATA 3 Gb/s and 1.5 Gb/s ports at reduced link speed) |
| Spindle Speed | 5400 RPM (capacity-oriented, not performance-oriented) |
| Cache | 128MB |
| Data Transfer Rate | Up to 140 MB/s (sequential, workload dependent) |
| Shock Resistance | Up to 1000G (non-operating) |
| Power Consumption | Low power for extended battery life (actual draw is platform dependent) |
Good to know
- Compatibility: The SATA 6 Gb/s interface is standard across most NAS adapters, controller cards, and motherboards, but the 15mm height will not fit slim laptop bays — this drive targets portable NAS, external enclosures, and industrial slots that accept thick-profile 2.5-inch drives.
- Family positioning: As a general-purpose mobile-class drive (related to Seagate’s Barracuda/portable lines), it is not a direct substitute for IronWolf (NAS), SkyHawk (surveillance), or Exos (enterprise) series, which carry workload-specific firmware and duty-cycle ratings; it works in those roles but without their workload certifications.
- Buying tip: If your priority is sequential capacity per watt in a compact form factor, this 5400 RPM drive fits well; if you need sustained random I/O, budget for an SSD tier alongside it rather than expecting HDD-class drives to fill that gap.
