Our box here is a Dell PowerEdge 2850 with the PCIe PERC 4e/Di U320 hardware RAID controller. The data drive is a RAID0 of 4 146GB 10K RPM U320 drives, and sustains, with ext3, over 140MB/s. We have successfully recorded 2 hours at 32MB/s without any known issues. Need to test further, though. > I installed the Reiser FS on my new laptop. I'll let you know if I > see anything hinky.

The 2.6 kernel-supplied XFS code has some problems, and you really need the latest SGI code instead. The CentOS 4 group is working on an XFS-enabled kernel with the newer code. Not sure where SuSE and Ubuntu/Debian stand. -- Lamar Owen Director of Information Technology Pisgah Astronomical Research Institute 1 PARI Drive Rosman, NC 28772 (828)862-5554 www.pari.edu _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
