I would think that knowing what is there and where should come first before the electronic storage.

Additionally, with the speed of current drives it would generally take between 4 and 5 drives on a single host SATA II interface to saturate the 3 Gbps, so the 6 Gbps is really just a nice to have.

I\’ve mentioned mdadm before in past articles. I haven\’t talked about it too much though. But if you notice, this article is about hardware, not software. In future articles I will cover some tools for Linux around storage. Actually I\’m really disappointed with the lack of open source storage management tools.

@jinn:
You are correct about needing several drives to saturate a single 3 Gbps interface. But drives are really cheap and you can easily build something to saturate the interface.

On the other hand, SSD drives can easily saturate a 3 Gbps interface. While I still can\’t afford to buy 3-5 SSD drives, it\’s getting closer than it was just a year ago. Moreover, there are some cool new projects for the kernel that use SSD\’s for caching block devices,

If data access becomes cache driven you will definitely start to see the age and limitation of a 3 Gbps interface and want a 6 Gbps interface.
