Description

The Maxtor DiamondMax Plus 9 120 GB (IDE/PATA version) is a model from the DiamondMax Plus 9 family, released around 2002–2003. This series was one of Maxtor’s last major IDE/PATA desktop lines before the shift to SATA, featuring high-density platters (around 40–60 GB per platter), 7200 RPM performance, and Fluid Dynamic Bearing (FDB) motors for quieter operation. It was a popular upgrade drive in the early 2000s.

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

The 120 GB IDE variant typically uses model numbers like 6Y120L0 (2 MB cache) or 6Y120P0 (8 MB cache, less common for this capacity but available in some batches).

Here are the key specifications (based on the official Maxtor/Seagate DiamondMax Plus 9 PATA data sheet and product manual):

• Capacity: 120 GB (120,000,000,000 bytes / 120 × 10⁹ bytes; approximately 111–112 GiB usable after formatting)
• Form Factor: 3.5-inch
• Interface: Ultra ATA/133 (also known as ATA-7 or Ultra DMA Mode 6) — maximum burst transfer rate up to 133 MB/s (backward compatible with ATA/100, ATA/66, etc.)
• Spindle Speed (RPM): 7,200 RPM
• Cache / Buffer: 2 MB (standard for most 120 GB IDE models, e.g., 6Y120L0) or 8 MB (on select variants like some 6Y120P0)
• Average Seek Time: ~9.3–9.4 ms (typical read; Maxtor spec ~9.4 ms average)
• Average Latency: ~4.2 ms
• Sustained Data Transfer Rate (outer zones, max): Typically ~55–70 MB/s (varies by zone; strong for its era due to high areal density)
• Internal Data Transfer Rate (max): Around 600–800 Mbit/s (~75–100 MB/s theoretical, sustained lower in practice)
• Bytes per Sector: 512
• Guaranteed Sectors: Approximately 234,375,000 (exact: 234,375,000 for 120 GB models)
• Number of Platters / Heads: Typically 3 platters / 6 heads (using ~40 GB per platter technology)
• Power Connector: Standard 4-pin Molex (IDE power)
