@scottalanmiller Why can we just not move towards larger SSD's? why are we still pushing the boundaries with spindles?
Cost. You can go buy bigger, faster SSDs today. But they are extremely expensive.
There are 8TB SSDs?
We've had 4TB since May. 8TB expected shortly. 2015 is the year when it is expected that SSDs will be larger than spinning rust. Late 2014 is the expected inflection point. SSDs might still yet pass spinning disks this year. The 10TB drives are not on the market yet.
Still, those have to cost between 5 and 10K for each drive.
$30K in September.
HOLY MOTHER OF...

Where is the use case for a drive that large that costs that much? Wouldn't it be less expensive and quicker to get a stack of 7.2K 2TB drives in a RAID array?

Probably in space, power and cooling savings, not to mention performance - but I'm more wondering, do people run those things in RAID 1? 60K DAMN!

If you need a million or more IOPS in 1U but need storage capacity, it would be the one choice. To hit similar IOPS from 7200 RPM drives would require roughly 8,000 drives in RAID 0. At 8K drives, you'd be looking at a drive failure every several hours, couple days at best.

Holy Shit! Power consumption, cooling requirements and space make 30K a bargin!

Believe it of not, it's cheaper to buy that card than to get the same IOPS from other drive types. Even using the cheapest drives you could find at $60 a pop, 7200 RPM drives would cost $480,000 to purchase and a lot more to put them in chassis, and a lot more to get the horsepower to handle the RAID and that's before we consider power consumption and cooling.

@scottalanmiller now the next question is - what kind of interface can handle 1 million IOPs? and what type of throughput would we be looking at?

PCIe. Everything in that category is raw PCIe, pretty much anything you see touting more than 100K or 150K is a card, not attached to a slwo SATA or SAS connection. It operates much more like raw memory.

How long, in theory, is it expected to take to get 10TB of data onto or off of a SATA drive? At maximum write speed, it seems like that would still take a very long timey wimey.

Did you see that in the US news today they said that "... doctor who got ebola...".
