What makes you think it would be better to go with RAID 1?

Well depends, RAID 1 can give you more space and redundancy and RAID 10 can give you less space, redundancy and performance. But I'm sure the OP just doesn't know the different between the two .
So depends on what type of hosting the client is using the server for (multimedia, static pages, heavy database, etc.). Depending on the usage, sometimes the performance of RAID 10 will not make that big of a difference but the additional space is a lot to gain. Just listing the services the client is using will not help in accurately choosing which RAID configuration to use.Email: info ///at/// honelive.com

I would never use raid 0 in a hosting environment unless it was a clustered solution, one drive fails your up a creek.
Go raid 10 its your best bet. Raid 0 if you have bad *** backups and I mean bad *** R1Soft type backups with bare metal restore features, otherwise raid 10█ Nick | BudgetVM

Raid ten is mirroring two striped arrays. If n = size of one drive, then capacity will always be n / 2 * number of drives. Whether you use four drives or 20. you get 50 percent of the capacity of all you drives.
Something to look at would be RAID 1+0 (not to be confused with 0+1). Its hard to find in a hardware controller, but way worth it. With six drives, you would have 3 separate mirrored segments, striped together. I believe performance will be a bit lower than than raid10, capacity will be the same, and it can sustain the loss of one drive from each of the raid one segments simultaneously without losing data. Thats 3 simultaneous drive failures for your situation vs 2 for RAID10.
Like I said, that can be hard to find and costly to implement, so if in doubt, just go with RAID10. make sure you put each of the striped segments on a separate controller though.

Partitions are easy
/boot 100 MB (Megabytes)
/usr 8000 MB (Megabytes)
/var 8000-25000 MB (Megabytes)
/tmp 8000 MB (Megabytes)
/ 8000 MB (Megabytes)
/home *Remaining Disk*
swap @X Ram MB (Megabytes)
Above is for cpanel
Plesk is even simpler
/boot 100 MB (Megabytes)
/usr 8000 MB (Megabytes)
/var *Remaining Disk*
/tmp 8000 MB (Megabytes)
/ 8000 MB (Megabytes)
swap @X Ram MB (Megabytes)█ Nick | BudgetVM
