I've never ever had to give me even more than a 2nd thought, also with the occasional drive failure.
3ware usually has constantly been absolutely rock-solid for my home storage assortment requirements. I eventually worked well my way up to a 7500-4, after that a 9500S-4LP, then a 9650-4LPML. I keep in mind getting to edit the linux driver source and recompile to work around a pest. I remember launching the motorists from floppy to use with both Home windows and linux. I started out with a 3ware Escalade 7000-4 way back again in the day time.
