I could see USB 3.0 flash drives with integrated RAID 0 taking off, especially if Windows 8 allows a portable version to install to 16+Gb thumb drives (speculation). In all seriousness, this drive is NOT for a consumer. In real-world applications, the difference between this and traditional SSD's is tiny when you consider most applications load up almost instantly.

What point are you arguing? At first storage, now speed on a flash drive.

Well: This array is 900 gigs and plugs into a PCI slot, therefore, it is going to use a much faster controller than a flash drive. My point is that this should not justify an $8000 premium. I think $11k is too much. That is all.

Actually, it regularly retails for 5-7 times as much as MLC NAND. ~$700 for a 64gb SLC drive is not uncommon. That's roughly $10/gb. http://www.newegg.com/Product/Produc...=64%20gb%20slc As an example.

We're therefore looking at a $2k premium, not $8k. A premium anyone needing this kind of performance would gladly pay, I imagine.

And that controller is exactly what you're paying extra for

1) Actually SLC does costs 3-5 times MLC NAND. That is just the cost of the NAND. SLC SSD cost more due to specialization (lower demand so less produced so higher prices).
2) This is enterprise hardware. Server hardware costs 2-10 times the price of consumer hardware.

There are a lot more differences than just the interface.

NAND quality.
Vastly more complex controller design.
Server Certification.
Cost of specialization.
Large capacitors for write-back in case of power loss.

You are basically comparing a moped to a sports car. Sure both are forms of transportation, have wheels, and are motorized....





Note, that RAMSan also sells RAMDrives. These external rackmount devices are capable of even more performance.

Can you use something like this to essentially work as RAM? At the office, every machine we use is minimum 24GB and we still go into swap a LOT.

Could you simply have let's say a server with 4GB RAM, one of these things and a HUGE swap allocation? It wouldn't be as fast as true RAM, but the price you'd have to pay to get 900GB of RAM into one machine is so astronomical that it would be worth it.

Hell, for large fluid simulation machines (dealing with several hundred million particles) we need 256GB+ of ECC server memory. Can you even image the cost of that? One 8GB stick of ECC mem is like $200 or more.

If we could drop in a 900GB SSD drive on a PCI card and have it even be half as fast as system memory, it would still be worth $10,000 to a company like ours.

It depends on the application and memory usage.

If performance is that important, then RAM is still the way to go. Dual channel DDR3-1333 will provide 16GB bandwidth at much lower latency.

It would probably end up being a blend of RAM and SSD cache.
