In this study they conclude that hitachi has the most reliable drives on the market.
Literally, one of the worst ways to figure this out, ever. It probably beats out the people who own 1-2 drives, see a failure and declare a brand worthless, but still very poor. They mention that Seagate has 31% market share... but over 40% in the region. It would be reasonable to expect then that that 9% came from competitors, who also are relatively smaller, but we do not know by how much and which ones. e.g. is one completely not present in the region?
Also, they mixed drive types (2.5" and 3.5") and included drives that needed recovery due to *physical* damage. Drop 3.5" drives off a 4m ladder onto concrete from any drive manufacturer and I would bet that there would be a lot of non-working drives.
All that being said, I am at something like a 6% AFR ATM (that is one dead drive though... and the drive "died" but I was able to pull all data off) and this is on the infant mortality portion of the bathtub curve with these 2TB Hitachis so I am happy.
.At this point, we also need to make very clear that the study is not representative and cannot be seen as a comprehensive reliability summary. It reflects only a very tiny fraction of the hard drive market. Drives are taken from analysis made during the recovery process, and there aren't specific test groups. It covers different form factors and different product lines, etc. Think of this analysis as an overview on reliability that might apply to the hard drives in your home city. Results very likely differ somewhere else.
I disabled the APM features on my RAID array because i had drives timing out. Unsure if its normal or my settings were bad or raid card compatibility thing so i just disabled it altogether because i dont have the time to eff with it.
Just purchased 3 x 7K2000's and one failed after 6 hours use so has been RMA'd. The other two I quick formatted and copied about 700GB of data to each. Both drives started reporting Raw Read Error Rates in SMART of 99 99 16 and a vairable data value whilst idling. But as soon as I start a surface scan the values reset themselves to default 100 100 16 0.
I spoke to Hitachi who recommended running the drive fitness test which failed both drives with error corruption. Hitachi's original reply to my query recommended doing a full format which I am doing now. I will then retest the drives using their boot CD. I am concerned though that if it is bad sectors on a two brand new drives that it fixes/reallocates then surely by definition these drives are faulty out of the box?

Frys now has this for $87 AR. Great price...
If you're seeing benchmarks of around 60MBps on your drives then something else is interfering.
...
Your Hitachi 2Tb benchmarks should generally look like this, at least this is what all my drives bench:
Hitachi 2Tb HDS722020ALA330 connected to LSI 9211-4i HBA (no cache):
will the 3ea firmware update work on the 20n drives?
Will Drive Fitness Test from Hitachi be good enough of a test?
Thanks odditory. I'm planning to add the two new drives to my array in a couple of weeks. Last time I extended my R6 from 7x2TB to 8x2TB it took ~3-4 days (on a Highpoint 4320), so I'm imagining it'll be the same or longer this time as well. I'll post back as info once it's done.
