Western Digital Caviar Green WD20EARS 2TB 64MB Cache
got 2-3 stars out of 5http://www.newegg.com/Product/Product.a ... 6822136514
Cons: Where do I start? So, here are the problems. 1) The drive uses a non standard 4K block size vs. 512 bytes, this throughs off many OSes like OpenSolaris 2) The drives "park" the heads every 8 seconds, so they park, unpark, park, unpark over 1,000 times per day in a normal environment. I had to write a program to ping the drives every 6 seconds to stop this... 3) Failure rate 3 out of 8 have failed in 18 months, this is too high... 4) performance sucks, 2 of mine read/write at 1MB/sec, thats the worst I've seen since 1990.
What is this park head the reviewer is complaining about and is it a serious problem? Do other HD have this problem? Why does WD engineer it to park the head so often?
