Small 2.5" external drives can be powered directly from USB. Big 3.5" external drives require a power supply.

I have used WD, Maxtor and Seagate.  My 2 Maxtor internal 80g drives died while my WD internal hard drives still work great.  That's why I like WD.

I cannot decide if I want to buy a mobile drive or desktop drive.  Desktop drives look much bigger than the mobile one but the size is double at the same price.

Mobile hard drives are designed to be tougher and quieter, hence the price.

I have two 2.5 (40/80) both from Samsung, haven't fail me yet.  I am hard on them with many dls.
I have one 3.5 (500) from Maxtor, still running great as my storage bin.

If you need to take your HDD with you, 2.5 is the way to go.  You wouldn't want to haul the 3.5 + Power supply around.

My 2.5 weights in at 138g and my 3.5 + power supply weights 3lb + ...

I have bad HD from any brand. As for my pick, WD would be my choice because of the easy warranty.  Go online, no registration require, just fill in the s/n, it tells you if it is still under warranty, then you can pick cross shipment, so you don't have to worry about packaging!

As for reliability, HD is not reliable, therefore, find some way to back things up!

At work, I get to RMA pretty much everything. Failure of HD can happen any brand, I can give you a run down on them. HD failure are mostly due to shock, electro-static, incorrected mounted (causing more shock) and simple overheat. Since none of the above can be traced easily, manufacturers all replaces them with a refurb unit.

Desktop 3.5":
Samsung - rarely see them, they have the best cost/GB ratio
Seagate - My preferred brand due to longer and faster warranty service
WD - Fastest drives across the board, most silent but slowest RMA service (totally ticks me off)
HGST - So many DeathStar in the past, unless they are that cheap, I would avoid

Mobile 2.5"
Samsung - rarely see them
Seagate/WD - Equally popular on higher-end laptop
Toshiba/IBM - One of the most common brand with little or no failure. Most failure due to heat or shock.

If it's external, I would definitely get the Seagate FreeAgent because it's easier and fastest to get warranty. WD on the other hand is super-slow, even I have the HD RMA through next day courier, the status does not get updated for 3 days and they ship back by STANDARD!!!

For internal, I am rocking my rig with 2 WD Caviar SE16 750/500GB, they beat my Seagate 320GB 7200.2 hands down. (note: size does not affect performance)

*don't tell me that Advanced RMA is available, the loss (exchange rate and handling) incurred on Advanced RMA is just not worth it.*

Toshiba/HGST/Samsung has to be shipped direct back to reseller or OEM.

If you want to most reliable storage, get yourself a Solid State HD, currently they come in 32GB or 64GB or 128GB flavors starting at $1299 each. They will last you a life time (5 years if used as primary HD on a system)

I just rebuilt my new gaming rig with the Q6700 + Antec Sonata II case. I always prefer my system to be quiet so I will not go for Raptor due to the noise, size, and heat limitation.

Maxtor is now Seagate, so the DiamondMax is history. I will still go for the 7200.11 even I am using the Caviar SE16 as my primary.

RAID gives roughly about 10-15% increase in large files transfer. Unless your video is over 2GB in size, you won't notice the difference. Rather, enabling NCQ and ACHI on SATA will give you significant speed-up compare to legacy IDE mode.

The Q6700 system you are building w/ 6 HD will require you to pick a motherboard that allows 6 SATA set up. Currently most mobo only has 1 PATA, and most has 4 SATA. My Gigabyte X38-DQ6 has 6 SATA on there, and I am using only 3 due to my 500W PSU and my 8800GT SSC. You also need to get a adequate PSU to supply enough power to all the HD.

If you are building a system that deals with a lot of CPU processing, get Vista. XP is not quite efficient to handle newest hardware like ACHI and Q6700. For the same reason, I am running all my games in Vista instead of XP.
