Genuine Seagate 500GB 2.5-Inch Solid State Hybrid Caching Storage Drive

Model: ST95005620AS | Series: Momentus XT Hybrid | Profile: 9.5mm Standard

The Seagate Momentus XT 500GB (ST95005620AS) is a high-performance 2.5-inch Solid State Hybrid Drive (SSHD) designed to bridge the gap between traditional mechanical storage capacity and solid-state speeds. It pairs a fast 7200 RPM spindle speed and a 32MB hardware cache with an integrated 4GB SLC NAND flash memory tier. Driven by Seagate’s proprietary Adaptive Memory™ technology, this self-learning hybrid architecture identifies your most frequently accessed files (like operating system boot paths and core application files) and mirrors them onto the ultra-fast flash layer, delivering significantly faster boot times and responsive system execution without sacrificing local storage space.

• Capacity: 💾 500 GB

• Spindle Speed: 🏎️ 7200 RPM (High-speed mechanical platter rotation)

• Hybrid Flash Layer: 🧠 4 GB SLC NAND Solid-State Flash Cache

• Interface: ⚡ SATA II 3.0 Gbps (Backward compatible with SATA I and forward compatible with SATA III slots)

• Form Factor: 📏 2.5-Inch (9.5mm standard thickness profile)

• Onboard Cache: ⚡ 32 MB Hardware Buffer

• Caching Technology: 🧠 Seagate Adaptive Memory™ (Self-learning firmware architecture)

• Acoustics & Power: 🤫 Quiet-seek acoustics with optimized power-saving idling profiles

• Seagate Adaptive Memory™ Engine: Built-in firmware dynamically tracks local data usage patterns. It automatically pulls your operating system's boot sequences and most frequently launched apps into the 4GB SLC NAND cache for near-instant execution.

• High-Speed 7200 RPM Performance Base: Spins at a rapid 7200 RPM rather than the slower 5400 RPM standard found in standard laptop drives. This significantly cuts mechanical latency and accelerates random read/write paths across the full 500GB capacity.

• Standard 9.5mm Structural Profile: Built to the traditional 9.5mm physical thickness standard. This makes it an ideal, direct drop-in replacement part for older notebooks, legacy laptops, rugged industrial PCs, and external drive bays that require standard physical clearances to seat securely.

• Target Systems:

  • Legacy Laptop Upgrades: A highly effective upgrade solution for legacy laptops from Dell, HP, Lenovo, ASUS, and Toshiba that natively support 9.5mm thick 2.5" drive bays.

  • Gaming Consoles: Directly compatible as a responsive internal storage replacement or upgrade for the Sony PlayStation 3 (PS3) and PlayStation 4 (PS4 / PS4 Slim), visibly accelerating game load times and UI snappiness compared to stock hard drives.

  • Retro PC Builds & Enclosures: Highly sought after for retro workstation designs or custom external backup configurations where users desire enhanced snappiness over traditional non-hybrid drives.

• Ideal Workloads:

  • Daily Multi-Tasking: Great for everyday productivity, handling office application suites, and accelerating frequently used application suites.
