Questions about this item
How fast does the 7200 RPM spindle actually make this drive in daily use?
The 7200 RPM spindle gives an average latency of 4.13ms, so data reaches the 16MB cache quickly for responsive application and file access.
What does the SATA 3.0Gb/s interface limit in practice?
The SATA 3.0Gb/s link caps the maximum transfer rate at 3.0 Gb/s, which is the ceiling for sustained reads and writes on this drive.
Will the 9.5mm height fit my laptop's 2.5-inch bay?
Yes, the drive measures 9.5mm tall, 69.75mm wide and 100.3mm long, matching the standard 2.5-inch 9.5mm form factor used in most notebooks.
