Sort of. LVM typically allows for a lot more than just RAID 0 - you can usually dynamically resize volumes, bind multiple physical volumes into a single volume, and more. > what about the "dynamic drive" in windows 2k/XP?

Windows dynamic drives can be a bunch of things - simple, spanned, RAID 0, RAID 1, or RAID 5. For details, see Microsoft's web site at http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q175761&; For a whitepaper on a Linux LVM implementation, see the SuSe paper at http://www.sistina.com/lvm_whitepaper.pdf. This paper also discusses the differences between RAID and LVM. This paper has benchmarks covering performance of the LVM.
