external hard drive comparison

Hello,

I am looking to purchase a 500 GB USB external HD and I'm seeing a big difference in pricing (e.g. at CompUSA Seagate 500 GB for $379 vs. Western Digital 500 GB for $199).  The specs look the same so I'm wondering why the big price difference.

Is there really that much of a difference in performance and reliability or is one HD pretty much as good as another?  What should I be looking for in deciding which to buy?

Thanks,

Steve

It would help if you posted the models you were looking at.  It's possible one has RAID the other does not.

Do they have the same Cache, the same rotational speed, RPM, the same interface, IDE, SATA, SATA II, ??

That must be know, and off course, the Warranty, as Nobus stated quite well.

Best Regards

Nothing ever in the clear!

This technical paper will help you implement VMware’s VM encryption as well as implement Veeam encryption which together will achieve the nothing ever in the clear goal. If a bad guy steals VMs, backups or traffic they get nothing.

I wouldn't buy finished products, as with those you can't be sure what drives get used. Buy yourself an empty USB HD Drive Case, then get those drive which suite you, or better, don't use USB at all, as that is somewhat flacky technology. If you can get and eSATA case (if your PC has eSATA), then connect a SATA drive to the eSATA connector. This'll be a lot faster and less prone to break. If your PC doesn't have eSATA, get a Controller (you can get them for laptops and desktops).

Don't buy either one.   Buy these:

(1)  500GB hard drive:  http://www.newegg.com/Product/Product.asp?Item=N82E16822148135

(2)  An external case (with 48-bit LBA support) ... Here's one for $10: http://www.newegg.com/Product/Product.asp?Item=N82E16817171012

Takes 5 minutes (max) to put the drive in the case; and you now have a drive with a 5-year warranty.   Almost all of the pre-packaged external units only have a 1-year warranty.

But if you do want a pre-packaged unit, the Western Digital MyBook 500 is a VERY nice unit => I've used these and they are VERY nicely done:  http://www.newegg.com/Product/Product.asp?Item=N82E16822136025
