Genuine Seagate 1.5 Terabyte Small Form Factor (SFF) 15mm Thick Storage Drive

Model: ST1500LM003 | Series: FreePlay (5400.3) | Physical Profile: 15mm (Thick)

The Seagate FreePlay 1.5TB (ST1500LM003) is a specialized, high-capacity 2.5-inch internal mechanical hard drive engineered explicitly for commercial storage subsystems, data backup appliances, and server array environments. Operating over a stable SATA 3Gb/s interface, it spins at an energy-efficient 5400 RPM and features a 16MB data cache buffer.

⚠️ CRITICAL PHYSICAL COMPATIBILITY WARNING: Unlike standard 7mm or 9.5mm laptop drives, this enterprise-class module features a heavy-duty, multi-platter architecture measuring an ultra-thick 15mm (14.8mm) in height. It will NOT fit into standard consumer laptops or thin client enclosures. It is designed strictly for enterprise servers, network-attached storage (NAS) towers, and industrial storage configurations built to handle thick 2.5-inch Small Form Factor (SFF) drives.

• Capacity: 💾 1.5 TB (1,500 GB)

• Interface: ⚡ SATA II 3.0 Gbps (SATA-300 / Backward compatible)

• Form Factor: 📏 2.5-Inch Small Form Factor (15mm / 14.8mm Thick Profile)

• Spindle Speed: 🏎️ 5400 RPM

• Onboard Cache: ⚡ 16 MB Buffer

• Alternate MPN: ⚙️ 9YH148-550 / 9YH148-552

• Motor Technology: 🤫 Fluid Dynamic Bearing (FDB) for quiet operation

• Command Features: 🛡️ Native Command Queuing (NCQ), S.M.A.R.T. Health Monitoring

• High-Density FreePlay Engineering: Built as part of Seagate's industrial FreePlay lineup, optimizing massive storage density within a tighter physical footprint than traditional 3.5" drives. This makes it a great choice for maximizing space in data centers.

• Rugged 3D Defense System™: Outfitted with robust mechanical safeguards, featuring an operating shock tolerance of 200 Gs. This protects internal read/write mechanics against sudden shifts or operational vibrations common in high-density multi-drive backplanes.

• Fluid Dynamic Bearing (FDB) Motor: Uses an FDB motor system to minimize mechanical friction. This ensures incredibly quiet acoustic tracking, low active power idling (averaging under 1W), and diminished thermal output.

• Native Command Queuing (NCQ): Features built-in hardware NCQ scheduling to efficiently optimize the execution order of received read and write commands. This minimizes head movement delays and enhances multi-tenant performance under complex system workloads.

• Target Infrastructures:

  • Disk Array Enclosures (DAEs): Excellent expansion choice for storage shelves designed for thicker 2.5" SFF frames, such as Dell PowerVault MD1120 or MD1220 systems.
