i don't disagree fully, but the difference here is that it's a business. if someone came out and said here's a $2m storage array for your house(!), we'd all scream and laugh and point fingers.
since it's a business, and (especially in this case) the storage array in question is a basic and required tool for the business to function, it doesn't seem to make sense for them to skimp on it.
what they came up with is cool. but that's not the issue. the issue is yet another (in this case small/startup) company saying "we're going to do X!!!" and then realizing "oh, shit it costs how much to do X right?" and then saying "fuck it here's some hard drives*".
