Tonight I finally built the raid 5 array I meant to do 10 years ago. The technology has come a long way, and the drives sure are bigger. I chose to go the port multiplier route. I am not really concerned about speed, and my Mini ITX board has only 1 PCI express slot. So I got these: ($162ea from MSY) And this: ($135 from techbuy +$10 shipping) Installed. Yes, it's dodgy. I need a new case. Recommendations? I'm looking at getting this if it can fit 5 or so drives http://www.aerocool.com.tw/images/case/M40/m40-photos/pages/3-2_jpg.htm Post is fine Device manager likes it Disk manager likes it too Format... Could take a while... I always do a full format the first time a drive is used. I chose 8k clusters which should be reasonable. Formatting speed So far I've been extremely impressed with how easy this was. Set jumpers, screw in drives, plug in cables, boot, format. That's it. Yes it's going to be slower than a true raid card, but it's for mass storage. 300mbit / ( 5 - the parity drive) = 75mbit each. Which is about the median speed of one of these drives anyhow. It does seem to be a bit slower than that, but it's still by any standards quite quick. Benchmarks to come later.
