That's why i said "Nearline SAS brothers" (i think Seagate may
be using "NS" for both "Nearline SATA" and SAS) too. the "AS" is
consumer SATA.  Sorry, they're both horrible drives.  Also, i had
a PE T610 with a bunch of 640SS (SAS) that all 8 drives
blew up (3 in the first year, all within 5 years) (We have 1,000s of
servers + hundreds of desktops and dozens of powervaults, so it's
not just a few random events -- we have a standing joke around here
"What kinda drive do you think FAILED out?  Oh, lookie here, another
340[AN]S!" -- I'm dealing with 2 systems right now where the PERC
keeps kicking them (340NS) out, then rebuilding on them :-( )
