Re: Mixing WD red with older seagates

[Tudor Holton <tudor@smartguide.com.au>]

Completely anecdotal evidence, but I was mixing WD Reds and Seagates in 
a QNAP RAID 6 each 3TB for a total of 6TB, and the Seagates kept making 
sounds like they were about to hurl.  Testing each drive individually 
with badblocks and smart came up with all drives OK.  But it kept 
chucking the WDs one by one.  Eventually I removed the Seagates and 
replaced them with WDs and since then no drives have been thrown out.

I can only theorise that there may be a timing issue between WD Reds and 
Seagate.
