SSD adapters using a SD or CF card compared to a SSD?

[tom2u]

Is there any point in considering getting a Sata memory card adapter then using a memory card (SD or CF I guess) instead of a regular SSD hard drive? Here's an example though the price here is high:

But if one could get the adapter much cheaper is this a viable way of getting SSD performance?

CF cards (and other removable media, even flash drives) don't have nearly the performance of an SSD or even a HDD. The random performance may be competitive but the majority of I/O on a client machine is sequential (although the most time on an HDD system is spent on random I/O).

Well, yes it would work (though not well). The question is; are you going to get a better value buying both devices rather than buying a regular ssd?

Most CF cards have a typical peak sequential read/write speed of < 90 MB/s. Compare that to a recent SSD with read/write speeds of 200-500 MB/s. There is simply no contest. A cheap 64 GB SSD would easily be more cost effective and better performing than a CF and SATA adapter.

Excellent explanations. Many thanks!
