oh, ho, ho -
all of you professionals are SO POLITE. What is going on is that Mr. Glawe did a "do it yourself" to SAVE MONEY, instead of buying a pre configured G-Tech, Cal Digit, Maxx Digital, Sonnet, Granite Stor, Dulce, etc. etc. And he read all these things about how fast the R680 was, and just looked for the cheapest components. Well, Mr. Glawe, you CAN call Jon Schilling at Stardom, to ask why your drives are dropping off like flies ! And you can call ATTO as well, but here are some clues -

1) Kyle Lodge was correct in asking for your ATTO NVRAM Device Wait Time and Device Wait Count - 3 and 1 are the default. They should be at 10 and 15 to insure your drives actually spin up before the ATTO freaks out and says that it has bad drives.
2) Mr. Modica and Mr. Brand are of course correct in stating that you should not be using CHEAP S@#$ drives in your "professional, fast" RAID array. But because so many companies just want to sell their products, they "qualify" non enterprise drives so that you will buy their product. Don't believe me - call ATTO.
3) As others have said - SEAGATE DRIVES SUCK - and specifically, they TIME OUT ALL THE TIME since 2009, which is when most of "us" changed over to Hitachi (and now Western Digital as well). So you can change your ATTO Device Wait Time, and Device Wait Count, and it might help you, but the bottom line is that Seagate Drives TIME OUT, and will never work properly with ATTO cards.
Use Hitachi or Western Digital, and your problems will go away.

As for Western Digital's comment on no RAIDs for WD drives - well, this is from Alex's link -

"Business Critical RAID Environments – WD Caviar Black Hard Drives are not recommended for and are not warranted for use in RAID environments utilizing Enterprise HBAs and/or expanders and in multi-bay chassis, as they are not designed for, nor tested in, these specific types of RAID applications. For all Business Critical RAID applications, please consider WD’s Enterprise Hard Drives that are specifically designed with RAID-specific, time-limited error recovery (TLER), are tested extensively in 24x7 RAID applications, and include features like enhanced RAFF technology and thermal extended burn-in testing."

So you see Christian, there ain't no cheap way out. You won't get your super duper performance for budget prices without LOTS OF AGGRIVATION. Get some Ultrastars, change those ATTO settings, and NEXT TIME, ask Jon Shilling for some direct advice at Stardom, before blowing your money.
