But the fact of the matter is that this is a dead technology. In the enterprise sector the pricing for high quality HDDs is not that much different from SSDs anymore.
There are tons of archival situations were cost per byte is far more important than speed or latency. In those situations, spinning disks still have a 5-10X cost advantage over SSDs. Decent quality HDDs do not fail that often when treated correctly unless you get a defective unit and today's lowest-power 7200RPM 3.5" HDDs operate in the 5-8W range, which is not that bad compared to 3-5W active power from SSDs.
The only HDDs SSDs might kill any time soon are those overpriced 10-15k RPM monstrosities.
As far as reliability goes, if your data is really important, you should be using RAID6 or some other forms of logical and physical redundancy regardless of whether you choose to use HDDs or SSDs anyway.
Is there really a market for consumer 8TB HDDs? I just assumed (perhaps incorrectly) that drives this size would only have a real use in more enterprise style solutions where the price per GB is closer to $0.20-.30/GB rather than consumer drives where data is a mere $0.05/GB. SSDs may still be more expensive than that, but in another year or so when these drive hit the market SSDs will have made up most of that difference while offering a host of other benefits (including reliability which HDDs just can't offer at those sizes).
The other big supposed use for these kinds of drive is surveillance so that you can store several months, or even a year of video on a drive. But this is Seagate, King of the 2 year warranty. Are we really going to see 2 year drives being thrown into appliance settings that may have lifespans of 5-10 years? How out of balance is that?
About the only use for these things is cold storage where you have a massive collection of movies that you don't watch all that often, but don't want to get rid of. And even there I would like to think I have a decent movie collection (granted I am not a big movie buff) and can easily fit all of my movies in ~1.3TB of space at native quality. I suppose I would need more space if more of my collection was in bluray, but even if it was we would be talking about ~2-3TB of storage... not 8TB.
I guess I am just confused as to who actually buys these things in enough bulk where it could be cheap enough to sell as a consumer drive, which is why I assumed it would be more expensive.
