Addonics creates CF SSD in 5.25-inch form factor

Uses CF or CFast cards to make SSD RAID drive


Addonics Technologies is now marketing the CF/CFast Drive, a standard 5.25-inch drive form that takes up to six Compact Flash (CF) or CFast media cards. The cards can act as independent storage units or be combined into a RAID group, creating a high-capacity Solid-State Drive (SSD). The individual trays can be positioned to face outwards for easy access or inwards to create an internal flash drive slot.

The 5.25-inch form factor makes it easy to fit the drive into PC bays or rack-mounted systems. Two types of drives are available, made either for CF or CFast media. Each type has a "independent slots" model or one with a built-in hardware port multiplier, which supports RAID 0, 1, 3, 5, 10, JBOD, Clone Mode (N-Way Mirror) or as individual drives.

The drives come without any CF or CFast cards, though Addonics also sells such media in capacities up to 32GB. The slots are connected to the host computer through SATA cables, which support SATA I, II and III transfer speeds. The drive supports PIO, DMA and UDMA and hot swap when connected to a hot-swap SATA controller. They work with Macs or Windows PCs with no software drivers required. Prices on the drives range from $135-199.

    bad idea

    CF does not make a good SSD, real SSD drives have various ways of overcoming write performance issues that CF, simply put, does not.

    Economics seem weak

    I'm not sure I see how this is useful in any real-world situation versus a dedicated SSD.

    Skimming through Newegg, you can get, for example, a 16GB CF card that promises 30MB/s write and 60MB/s read for $55. Times six, that's 180MB/s write and 360MB/s read, and a total of 96GB of storage (if you do straight RAID0), for $330 + $130 for this thing, total of $460.

    A top of the line OWC Mercury Extreme will get you 240GB for $500, with read and write speeds in the 250-280MB/s range. Heck, you could buy two 50GB OWC RE drives (which have massive overprovisioning) and stick them in a RAID0 array to match that 100GB (but with redundancy), and theoretical read/write throughput of 500MB/s, for $360.

    I just don't see the economics of this coming out ahead of a regular SSD, without the added risk of one of the cards failing on you. And if you're running a RAID5, you're basically doing the same thing as overprovisioning but with the cost of a lot of RAID overhead.

    Maybe it's for photographers who have a lot of huge, fast CF cards laying around and want something useful to do with them.
