[mythtv-users] Hard Drives that Actually Work?

I have more experience with disks as a result of the 300 or so I have in 
my clusters, rather than MythTV. I have seen many disks fail, but things 
seem to be improving. Most disks I find, if they are going to fail, fail 
in their first year. So multi year warranty is a must. 

Any manufacturer can be bad, but disk from 2002 to early 2004 were 
probably the worst from many mfg. This is the period when the disk mfg 
reduced warranties for retail drives to 1 year.

Things seem to have improved. Seagate recently increased their warranty 
to up to 5 years on SATA drives. Some of the other mfg have followed suit.

My experience is that I have moved away from Maxtor and WD to seagate. 
Overall I am so far finding Seagate disks to be more reliable. I based 
this on experience, and the fact that seagate provides some of the best 
warranties out there. Warranties are a gamble on the par tof the mfg so 
they seem to be confident in their products. I also only use SATA which 
I have also found to be of superior reliabilty, although I have only 
deployed a dozen or so SATA disk.

My comment is you never know. Disks fail for a variety of reasons, and 
it is best to assume you will have a failure at some point.

To mitigate the risk I recommend either RAID1 or RAID5 software 
mirroring if you actually care about your data otherwise go with the 
disks with the best warranties. They may not last longer, but at least 
you can get them replaced. Also go with SATA if you can. SATA has some 
nice features that (if you have the right controller) can reduce some of 
the load situations that increase the wear and tear on your disk.
