Questions about this item
How often does the 16MB cache need servicing or replacement?
The 16MB cache is solid-state memory soldered to the drive electronics and requires no maintenance or replacement during the drive's lifespan.
What limits sustained write performance on the SATA 3.0Gb/s interface?
The 7200 RPM platters and 16MB cache set the sustained throughput ceiling, while the SATA 3.0Gb/s link provides ample headroom for typical workloads.
How much noise and heat does the 7mm 7200 RPM drive produce in all-day use?
The 7.0 mm thin form factor and 7200 RPM spindle generate modest acoustic output and warmth comparable to other 2.5 inch laptop drives under continuous operation.
