Questions about this item

How often should the 7200 RPM spindle bearings be checked or replaced?

The 7200 RPM spindle is sealed and requires no scheduled bearing service.

Will the 16 MB buffer become a bottleneck during long sequential writes?

The 16 MB cache handles burst traffic; sustained write speed is limited by the 7200 RPM platter transfer rate.
