best is whatever you DON'T have unless someone else paid for what you DO have. :-)<br><br>Seriously, enterprise drives are better than home use drives. Within each classification, the differences between drives are negligible over their lifespan. warranties are a good indicator of how well a drive tested out at the manufacturers facility but not a good indicator of how it will work in your gear with your loading, cooling, vibrations and power.<br>
<br>Newer drives (i.e. higher capacity) seem to be more sensitive to temperature than drives from 5 years ago. SAS drives seems to be able to take temps than would melt most cheeses. <br><br>In short: how much money do you have? It's often easier to build a RAID10 and have a spare pair for cheaper than buying a pile of expensive drives with longer warranty. Many people have drives that are 10 years old and doing fine. <br>

Hey all,<br>
<br>
I'm looking to replace some 1TB HDDs in a s/w RAID-10 array with some<br>
2TB models. The existing drives have been running flawlessly for a few<br>
years, so they are due to get swapped out anyways. I did have one disk<br>
fail a year or so ago so it was swapped out, and I bought a cold spare<br>
at the same time so I have one more spare (of the same type/model as the<br>
replacement drive). So I'm looking for another pair of drives that I<br>
can use as the mirrors (so each mirror has one of type/batch-A and one<br>
of the yet-to-be-bought set of drives).<br>
<br>
Of course, when I bought the drives warranties were 3 or 5 years, not<br>
the '1 or 2' years they are now. So I'm looking for the "best value"<br>
2TB drives available today -- lowest price for highest quality + good<br>
warranty. It looks like I can pretty much only choose between WD and<br>
Seagate nowadays -- I guess lots of consolidation in the market? (My<br>
existing drives were Hitachi, which in my experience were always great<br>
drives).<br>
<br>
What's the current going theories and best practices? Any concrete<br>
suggestions (links to NewEgg or some other vendor would be appreciated).<br>
<br>
:)<br>
<br>
Thanks,<br>
