Internal/External: Internal hard drives are found inside the computer and are connected either via IDE connectors or SATA connectors. They stay inside the computer until the user is ready to upgrade. External hard drives are located outside the computer and are connected either via USB or Firewire connectors. External Drives come in various portable sizes and can easily connect to other computers.

Interface: The hard drive can be connected to the computer via various connectors. IDE is the more standard internal connector. SATA (or Serial ATA) is a more advanced connector which is faster than IDE. SATAII is even more advanced than SATA and can go almost twice as fast. USB 2.0 and Firewire are the standard connectors for external drives. USB 2.0 has a transfer rate of 480Mbps; Firewire 400 has a transfer rate of 400Mbps; Firewire 800 has a transfer rate of 800Mbps. However, differences in the architecture of the two interface types allows Firewire it have a faster sustained thoroughput.

Lots of Clicking
Rating: 3 Star Review
Strengths: Lots of storage space. Good speed
Weaknesses: Lots of Clicking Noise but I think it seems to be normal on these drives.
Review: I'm using this driver for video storage, more then 400 GB. So I'm afraid from losing my data because the clicking. But it's not meaning it is a bad drive 1 TB is not a small driver.

Quiet Hard Drive, Fast, Quiet, and Only a Small Premium
Rating: 5 Star Review
Strengths: Fast 7200RPM, ATA100, QUIET
Weaknesses: A small pricing premium
Review: Get a Western Digital or a Maxtor, you'll really hear the difference. I've had 4 7200RPM hard drives before, but this one is just amazing in terms of speed and quietness. It does have a slight premium, but you pay for what you get. On top of that the 3 year warranty is so much better than the others ones that last only 1 year.

Rating: 4 Star Review
Strengths: Overall size and price
Weaknesses: nothing
Review: This is my second Western Digital portable hard drive purchase and must say i don't see much difference overall outside of the convenience in size killer price. Great for throwing into backpack or duffel bag going back and forth to work or school.

Good Item
Rating: 3 Star Review
Strengths: Design, Storage capacity
Weaknesses: Noise
Review: This external is pretty good, it does its job & 1TB is definitely a great amount of storage for all my files. I like the design of this, but I find it be a bit nosy when I transfer items from my external to my mac & vice versa.

Rating: 4 Star Review
Strengths: cost, ease of installation in XP
Weaknesses: only 1 year warranty
Review: I purchased this for $89 before a $50 in rebates bringing the price to $39 for a 80 GB drive with a 8 MB cache. The drive is very quiet and runs cool. I am currently using this in a RAID array without any problems.

Great Value
Rating: 4 Star Review
Strengths: Quiet, easy installation, fantastic "bang for the buck."
Weaknesses: If you're looking for a high performance drive, this is not the one. Otherwise, none.
Review: Overall, a good drive for most systems. I have it installed for additional storage and occasionally use it in a USB container. The drive performs very well for a reasonable cost. Like most components, if you want extreme performance, you'll pay a lot more. Nice long warranty, too!
