We use SATA DOMs a few times a month in many of the NAS products we test. I've pulled two SATA DOMs in the past to run tests on their performance, but both times we killed the drive. SATA DOMs are not built for high write environments, and CrystalDiskMark's 4K write test is all it takes to kill a regular SATA DOM.
Anytime you have "extreme" in your company name you have to do things a little differently, a little better, and stand behind the claims. Mach Xtreme has made a name for itself in Europe for selling reliable performance SSDs. The company has limited penetration on this side of the pond, but with the SATA DOM, we think that will change with a select group of customers.
SATA DOMs are essentially SSDs in a very small form factor package. The drives are usually 4GB to 8GB, but some go all the way to 64GB in capacity. Their purpose is to have a space large enough to hold an embedded operating system for devices like NAS, routers, firewalls, and so on. New motherboards from ASRock and Supermicro that use Intel's latest SoC Atom have increased interest in DIY NAS products.
NAS products are just the starting point though; software like Pfsense and Smoothwall can turn an old computer into a very powerful router and firewall. While a full size hard drive will work for the task, why use that much power to store what is normally just a couple of hundred megabytes?
DOMs are very low power, very small, and offer enough storage if needed to install Windows Server 2012 R2. Now, they also come in an Xtreme version!
