Not Dead Yet: WD Releases New 6TB 2.5-Inch External Hard Drives - First Upgrade in Seven Years

This is a most excellent place for technology news and articles.
why?
Very high failure rate. even sony 2.5's have a similar rate of death. For some reason this form factor is just terrible for longevity
Bingo. Sorry, had typed a reply about my failure rate and difficulties getting an RMA but forgot to submit.
My bet is on density. You cram so much in such a tiny space, so any tiny imperfection or fault will corrupt the data or render the drive unusable.
At the time it was fine. I had an array of 4tb drives that I was backing up with a series of 5gb drives. They were just so unreliable; all but one failed while the array they backed up is still spinning strong.
Not exactly reliable and less than easy rma process.
Sorry, had typed this and forgotten to hit submit :(
