In a previous post on DMX-4 I discussed the use of SATA drives in enterprise arrays. A comment from our Storage Anarchist challenged my view of the resilience of SATA drives compared to FC.
Now unless I’ve been sleeping under a rock, the storage industry has over the last 5 years pummelled us with the warning that SATA are not enterprise arrays, the technology having derived from PC hardware. They were good for 8/5 rather than 24/7 work and not really suitable for large volumes of random access.
Has that message now changed? Were we fooled all along or is this a change of tack to suit the marketers?
What do you think? Are SATA drives (and I mean an *entire* array) in an enterprise array acceptable now?
