Hi all
I have about 350TB on ZFS now, and with an old box with WD Greens (those
getting replaced as of now), I've had very little drive failures. iostat -en
shows a minimum of errors, and all is well.
Then, the new 100TB setups are based on FASS drives (2TB WD Blacks). Those seem
to be rather worse in the terms of expected age. We've replaced seven so far,
out of 158 in total, so it's not that bad, but even the newer ones seem to show
high error rates. Some of the drives that have been returned, have shown no
errors with WD's tools.
So, does anyone know which drives to choose for the next setup? Hitachis look
good so far, perhaps also seagates, but right now, I'm dubious about the blacks.
Vennlige hilsener / Best regards
roy

There are people who have lost data on Seagates, and so swear they'll never use
them again; there are people who have lost data on Hitachis, and so swear
they'll never use them again; there are people?.
I have a bunch of Seagates that I'm using to clone the internal drive (Seagate)
of my iMac for offsite backup purposes. No problems, but only minima use really.
Generally get the drive with the longest warranty period: this is usually an
indication that the manufacturer is willing to put their money where their
mouth is when it comes to longevity claims.
Of course WD FASS Black devices come with five year warranties, and that
doesn't seem to be helping you much. :)

Hi! I'd go for WD RE edition. Blacks and Greens are for desktop use and
therefore lack proper TLER settings and have useless power saving features that
could induce errors and mysterious slowness.
Yours

I can confirm that on *at least* 4 different cards - from different
board OEMs - I have seen single bit ZFS checksum errors that went away
immediately after removing the 3114 based card.
I stepped up to the 3124 (pci-x up to 133mhz) and 3132 (pci-e) and have
never looked back.
I now throw any 3114 card I find into the bin at the first available
opportunity as they are a pile of doom waiting to insert an exploding
garden gnome into the unsuspecting chest cavity of your data.
I'd also add that I have never made an effort to determine if it was
actually the Solaris driver that was at fault - but being that the other
two cards I have mentioned are available for about $20 a pop, it's not
worth my time.
I don't recall if Solaris 10 (Sparc or X86) actually has the si3124
driver, but if it does, for a cheap thrill, they are worth a bash. I
have no problems pushing 4 disks pretty much flat out on a PCI-X 133
3124 based card. (note that there was a pci and a pci-x version of the
3124, so watch out.)
Cheers!
Nathan.
