What is the difference between the ES.2 and 7200.11 drives?  I am looking at the 750GB Drives, both have the same 32mb cache, both appear to have the same stats.  I do plan on putting them into Raid 5.

Thank you,

Steve

I would go more for the 7200.11's their probably more suited towards your use, and how many are you planning on buying?

What will you use the storages for? If just for you personal and family affairs, the 7200.11 is more suitable for you.  And if you want to use them in the servers of service providing, the ES is perfect.

Anybody have any ideas on this?

I plan on using these in Raid 5 for Media storage and playback as well as a secure place for diasaster recovery files.

Are there any real performance or stability differences in one over the other to make the cost difference worth it.

Here's my two cents - 7200.11 have a rated MTBF of 750,000 hours.  ES.2 have a MTBF rating of 1.2 million hours.  Roughly and theoretically speaking then, ES.2 drives should last half again as long as the 7200.11.  Of course the statistics do not indicate how long any given hard drive will last, just the likelihood.

If the 7200.11 drives lasted an average of five years and ES.2 lasted an average of seven+ years, imho, the additional cost would be worth it.

unicorncomputer - considering your proposed usage - part of the answer lies in your "disaster recovery files" and what other backup medium you have in place.  If your really want to be increase the chances that your Raid 5 array stays up and if your are planning on 24/7 operation, I'd lean toward the ES.2 drives.
