Advice is like opionions, everyone has them. I use ESata and USB, without a problem.
I use an AZiO ADP-SU33, USB2.0 & eSATA HDD Docking Station, and an external USB2.0 & eSATA HDD enclosure. The only drawback issue has been the ESata is not "hot-swap".
Other's on this forum would advise you not to use external drives, and I would agree with that in regard to 24/7 usage. I now 2 Seagate 1T (ST31xxx340AS) that are 2 yr old bricks. Both were on 24/7. Could have been it was the problem with the 7200.11 CC34 revision's.
I also have 4 Seagate 1T (ST31xxx528AS). One is in my computer, and 3 are on standby, clones of my system. The clones are shelved.
My suggestion: Check with Dell (they have been exceptionally helpful recently) concerning any BIOS or MOBO issues with a 2T. Then replace your internal drive by cloning. Try to eliminate some of those external drives by combining into either 1T or 2T. Then back up those partitions (data) to the older drives your going to shelve off-line.
I'm not very tech savvy but I am really trying to research and figure out what the best External Hard drive for under 150 bucks would be that would be fairly fast for my Dell XPS 420. I have 3 other External HD's connected to my comp. Two WD My book's and a Iomega. I need to upgrade because I am running low on space on all of them. I would like to get a 1 TB or even a 2 TB but I am so unsure of what hard drive would be the best? Is shelling out for a My Book 3.0 a good idea? I was thinking of it but then got nervous when I read the negative review someone posted about mother boards not really taking on the true speed that is capable with USB 3.0. I am also nervous about getting an Esata for my Esata drive that is available since someone mentioned them being unreliable. Should I just stick to another USB 2.0?
Are LaCie drives undependable for PC's? What is the best bang for my buck for under 150 dollars. I kind of WANT to upgrade to a 2 TB so I don't have to worry about space but I don't want to worry about both price AND size and juggling which I need to decide over.
Suggestions would be greatly appreciated. I have no idea what to look for! haha
