I see so many whose cheapo raid crashes. Best is 3ware 9500 series. Any out of that series in a raid5 will do fine. Like 8 x 250 GB in a raid 5 gives effectively a diskspace of 7x250GB. You can pick up those 250GB drives for 80 euro here. Perhaps even cheaper in USA. Of course safest is raid10. In combination with such a 3ware controller the safest way is a raid 10 array of say 2 TB. 16 x 250GB s-ata. Such a combination can host Oracle databases of $100k too :) Most financial companies expensive oracle databases get actually hosted at a raid10 array (usually using U320 scsi disks, in which case you don't need 16 drives for a 2 TB array, but more like 88 disks and $200k). A good hardware raid controller is important. HP has some for like $5000 too. However you can build it cheap yourself. For a good storage i advice this 3ware 9500 series with raid5. You can also take the risk of course of raid0. If 1 drive fails, you lose of course the entire raid array, in case you stripe. Raid5 allows you to lose 1 harddrive and then you just replace that drive and it runs further without problems. Raid10 means all drive has 1 backup and you have the same writing bandwidth like a raid0 array. Writing speed for egtb's is not important, except for those who generate them. So i look forward to win the toto, so that i can buy a 2TB raid10 array :) In any case, raid is a very cheap way to get a huge storage for little $. Vincent
