Western Digital Green 1TB Internal SSD
✅ Key Features
-
It’s an internal solid-state drive (SSD) with a 1 TB capacity, using the SATA III interface (6 Gb/s) in a 2.5″ / 7 mm form factor.
-
It uses no moving parts (typical of SSDs), which offers better shock-resistance and quieter operation compared to mechanical hard drives.
-
It supports SLC (single-level cell) caching (in the underlying controller/firmware) to help boost write performance for everyday tasks.
-
It is marketed for everyday computing: desktops, laptops, general use rather than heavy enterprise workloads.
-
Low power consumption: suitable for laptops where battery life matters.
-
Comes with a 3-year limited warranty (for many regions) from the manufacturer.
