Things you should know about external hard drives

June 29th, 2010
  • Depending on availability of parts during production, the internal hard drive in an external enclosure could be either SATA or EIDE.
  • They can only guarantee drive capacity. They cannot guarantee a particular internal hard drive model, data interface, rotational speed, or cache size in the external hard drive enclosure.
  • Dismantling any single-drive external enclosure to obtain this information will void the warranty of the hard drive.
  • Interface and cache of the hard drives inside the external enclosure does not affect the performance or the data transfer rate of the external hard drive unit.

Note: With the exception of eSATA and USB 3.0 external hard drives, USB 2.0 and Firewire 400/800 have yet to approach the transfer rates of the internal hard drives we use in our external enclosures.
