RAM instead HDD/SSD.

I don't pursue any promotional purposes, but never heard about such drive before.

I'm looking for new config for my home pc. Before this article I thought to build RAID-0 with 4 sata drives, but now i would better buy this device.

This may work if your server's RAM is already capped out. You can already use RAM as virtual disk space, so this looks more like a way to add more RAM to a system through the SATA bus (perhaps with some extra interface sugar). Although, the main memory throughput can easily overwhelm a SATA bus. It's an intriguing piece of hardware, I am waiting for some reviews.

Very nice. But what happens when the power fails? RAM can't preserve state without power...

  Most of these units have an internal battery and CF card or other flash storage - when the power goes out, the battery lets them write the contents of their RAM to the permanent storage. There are also other options than the one linked: http://www.ddrdrive.com/ http://www.ddrdrive.com/ - pcie card, favored by many people running ZFS http://us.test.giga-byte.com/Products/Storage/Products_Overview.aspx?ProductID=2678 http://us.test.giga-byte.com/Products/Storage/Products_Overv... - Gigabyte's i-RAM, very similar to what's linked.

This is an interesting product, and there have been others like it before, but what a shady looking company to be selling it.

SATA2 interface and DDR2 RAM... A major OUCH! That's like putting Bugatti Veyron Super Sport on a narrow and curvaceous country road: A pinhole that's just stopping it from literally flying (well, speed-wise, not altitude-wise). On the top of my list as a consumer grade drive (thou, we're considering to put it into the Win2008/SQLServer server on our LAN ) is OCZ Revodrive X2 PCI-Express SSD (http://www.ocztechnology.com/ocz-revodrive-x2-pci-express-ssd.html http://www.ocztechnology.com/ocz-revodrive-x2-pci-express-ss...).

Aside from the seek times, this guy gets destroyed by the latest crucial SSD drive. http://www.newegg.com/Product/Product.aspx?Item=N82E16820148349 http://www.newegg.com/Product/Product.aspx?Item=N82E16820148... If you want high speed ram-based drives, FusionIO is the way to go http://www.fusionio.com/products/iodrive/ http://www.fusionio.com/products/iodrive/

I was following until I got here: It also offers 100% secure file deletion (disconnect both the external and the internal power!). Flash drives can't offer this. Hard disks suffer from magnetic remnance and so retain their data even after they have been overwritten several times! But the HyperDrive5 is forensically wiped every time the power is fully disconnected Wait a minute, if the drive gets accessed quickly or if it's really cold, RAM actually retains its contents. You can't expect the charges to suddenly revert to randomness! Plus, this presents a major issue if someone wanted to sabotage you... If it's really that easy to clear the contents, someone may just come and clear it for you while you aren't looking.
