RAID mirror and striping question

[unkn2232324]

Is it possible to setup a RAID configured as follows:

2 WD Raptor 74 GB 10000 RPM drives striped as 1 148 GB drive.
and then these mirrored to
1 160 GB generic SATA 7200 RPM drive?

Thanks

G

If your RAID controller supports RAID 10 (1+0), it might be possible.
However, wouldn't your performance be dragged down to the performance of the
slower HD?

Sure, if your RAID controller supports RAID 5.

That's not worth the effort because you'll lose the extra read/writing speed
of the two striped drives as you mirror this onto a single drive. But, yeah.
Should be possible. Rule is: The speed of your raid will not exceed the
speed of your slowest disk in the raid.
