Questions about this item
How do I install this 2.5" SATA drive in a laptop and what step is often missed?
Mount the drive in the 2.5" bay, connect the SATA data and power cables, then secure it with the caddy screws — the step often missed is fastening the caddy so vibration does not loosen the SATA connector.
What maintenance or replacement will this 320 GB Travelstar 7K500 need later?
No scheduled maintenance is required; plan to replace the drive if SMART reallocated sectors rise or if the 7200 RPM spindle develops bearing noise after years of use.
What limit appears first during sustained writes on this SATA/300 7200 RPM drive?
The SATA/300 interface caps sustained throughput at 300 MB/s, so the 16 MB cache fills quickly and the 7200 RPM platters become the bottleneck during long sequential writes.
