A NCR875 based card (like the Diamand Fireport 40) are pretty cheap, and fast. The Adaptec 2940 series performs a bit better handling lots of requests, but is kinda of expensive. However, some motherboards come with aic7880 (Adaptec) UW controller on the motherboard, for way less. > Ultra Wide card), and am debating which drives to go with it.

I've heard some people really complain about the Micropolis I have two Micropolis 3243 drives. I don't belive they make these anymore, as I got mine almost two years ago. I hate them. One of them is flaky (locks up, and requires a _power cycle_ before it will respond to a problem). They also run hot. I don't reconize that Seagate model number, but I like the Seagate Barracuda 4LP or 4XL series. I have about 15 2GB and 4GB 4XL or 4LP drives, and they work well. Very reliable, and very fast. No failures to date (they are used 24x7). > Concerning the swap area (which will be on these drives), which is better: > setting the drives to be entirely consumed by the ccd partitions and > putting the swap within the virtual ccd, or just leave some free space on You can put swap in the virtual ccd?
