Description

The Seagate ST3160815A is a model from the Barracuda 7200.10 series (PATA/IDE version), released around 2006. This family introduced perpendicular recording technology, allowing higher capacities and better reliability compared to prior longitudinal recording drives.

*** Hard drive is tested for good S.M.A.R.T. , no bad sectors and is formatted as an NTFS partition.

Here are the key specifications:

• Capacity: 160 GB (160,000,000,000 bytes / 160 × 10⁹ bytes; ~149 GiB usable after formatting)
• Form Factor: 3.5-inch
• Interface: Ultra ATA/100 (also called ATA-6, Parallel ATA / IDE / PATA) — maximum burst transfer rate up to 100 MB/s
• Spindle Speed (RPM): 7,200 RPM
• Cache / Buffer: 8 MB
• Average Seek Time: ~8.5–9 ms (typical read)
• Average Latency: ~4.16 ms
• Sustained Data Transfer Rate (outer zones, max): Up to ~78–85 MB/s (depending on source; perpendicular tech helped achieve higher densities)
• Internal Data Transfer Rate (max): Around 1,000–1,200 Mbit/s (~125–150 MB/s theoretical, but sustained lower)
• Bytes per Sector: 512
• Guaranteed Sectors: 312,581,808
• Recording Technology: Perpendicular Magnetic Recording (PMR) — first major Seagate desktop series to use this
• Number of Platters / Heads: Typically 1–2 platters (high-density 160 GB/platter class at launch)
