Refurbished SEAGATE SAS Hardisk 1TB (ST1000LM035)

Capacity: 1 TB (≈ 1000 GB) of storage – enough for OS + applications + moderate media/files

Spindle Speed: 5400 RPM – slower than high-performance 7200 RPM drives, but quieter, more power‑efficient.

Interface: SATA III (6 Gbps), compatible with older SATA versions.

Cache (Buffer): 128 MB – helps with burst transfers and reducing latency during random reads.

Form Factor & Thickness: 2.5‑inch, 7 mm thin – fits in slim laptops, ultrabooks, 7mm bays.

Power Consumption: Low idle power (~ 0.45 W), modest power under load (~ 1.6‑1.7 W) – good for battery‑powered or thermally constrained systems.

Sector Format: Advanced Format 512e (logical 512 bytes / physical 4096 bytes) – modern format, more efficient on larger disks.

Shock Resistance: Operating shock 400 G (2 ms), non‑operating shock ~1000 G (1 ms) – decent robustness.

Load/unload cycles: Rated at ~ 600,000 cycles – durability for many mounting / powering cycles.

Noise & Acoustics: Quiet‑step ramp load technology, relatively low audible noise due to lower RPM. (Not silent, but better than faster HDDs).

Operating Temperature Range: ~ 0°C to 60°C – standard for laptop drives.

Nonoperating Temperature / Environmental Rating: −40°C to ~70°C, RoHS compliance, halogen‑free components.

Sustained Transfer Rate: Around ≈ 140 MB/s for sequential reads/writes under good conditions.

Weaknesses: Lower random read/write performance (due to 5400 RPM and/or SMR if that version), higher access latencies vs SSD or 7200 RPM drives. Not ideal for I/O‑intensive tasks.

Refurbished Status: Since this is “refurbished,” potential concerns include reduced lifespan, prior wear (e.g. from power‑on hours, number of spin‑ups, bad sectors). It’s important that the refurbishing includes testing for bad sectors, SMART checks, and ideally warranty (short term) from the refurbisher.
