Not sure if I'm getting as good performance on my RAID as I should: Do these numbers look right?

I have an HP ML350 G5 with a 6-drive hot-swap drive cage.  I have 6 SATA 7200 RPM 250GB drives in it in a 1+0 RAID configuration.  Note the ML350 G5 uses an E200i RAID controller with 128MB cache and a BBWC.  I have the read cache at 64MB and the write cache at 64MB.  With this configuration, I ran a performance tester ('s Performance Tester V6) and got these numbers:

Sequential Reads:  62.1 MB/s
Sequential Writes:  34.0 MB/s
Random Seek + RW: 12.3 MB/s

I also ran HDTune, another performance tester.  This is what HDTune reported:
Minimum: 43.1 MB/s
Maximum: 63.2 MB/s
Average: 53.6 MB/s
11.2 ms
Burst: 108.2 MB/s

(that is MB, not Mb)

Does this sound right?  Or does it sound like I have some hardware problem degrading my performance?  I was expecting a bit more impressive numbers...
