>From a Seagate engineer: *They can be the same drive design but a lot of the external drives are early units with relaxed specs for error rates usually and can be waterfalled (by this I mean design capacity is higher but could not meet the OEM specs or full capacity during testing, helps with thruput yields) from higher capacities. The basic reliability should be very similar if the design point is the same. External 3TB's or any capacity point may vary from box to box may have multiple different drive designs types which meet the capacity but can vary by performance and capability. This is true for internals to a lesser degree. Drives that go to retail (Bestbuy etc....) have the lowest reliabilty specs to ship with OEM's being the toughest. I should also state that internals typically have tougher vibe and temperature specs with higher duty cycle life expectations, a lot of externals are merely back up hence the lower quality requirements.*
