Solaris10 (zfs) random write was as fast as veritas and much faster than all the others (~300MB/s versus 150-ish).
I'm now running btrfs and am quite happy with it, should probably run those benchmarks again and clean up the page a bit http://www.crystalconsulting.eu/bench/
I did quite some testing on ZFS using FreeBSD and Solaris and am not so impressed with ZFS anymore. Sure it is a lot faster than vinum raid, but it is not very flexible. On both Linux and Solaris, Veritas was a lot faster.
Note: this was with FreeBSD7 rc2, not the release version.
Some results; not made into a nice page yet http://www.crystalconsulting.eu/bench/

Looking at spec.org jEnterprise2010 scores:
http://spec.org/jEnterprise201...
http://spec.org/jEnterprise201...
A T5-2 gets a jEnterprise2010 score of 17k, an X4-2 11k (with half the memory and Oracle Broken Linux 5.9, why not 6.*?).
The sparc has a list price of ~68k USD. Not sure what a two socket Oracle intel box costs; maybe 15k or so?
sparc; 4 usd/score
intel: 1.36 usd/score
Sparc was nice once, but that was ever so long ago..
I did some benchmarking a while ago on freebsd7 solaris10 and centos4.6, all on the same hardware. At the time, Veritas came out quite well.
on 8 disks, raidz/5:
FreeBSD7: 144/73 MB/s r/w using dd
Solaris10: 150/92
Fedora7 md raid: 164/130
Solaris/veritas: 169/35
raid0/stripe:
FreeBSD7 (zfs): 236/155
Solaris10 (zfs): 169/132
Fedora7 (md0): 259/188
Centos4+vertias: 236/270

In short; it just works.
My wife has an iphone, which is very nice, but it needs to be charged every night...
It is starting to fall apart a bit though; maybe I should see about getting a newer one.

My nokia 6310i has a "pager" mode, when you receive an SMS, it keeps beeping as loud as it can until you do something.
Very annoying, but can also be very useful.

Hardware: AMD X2 3600, 3GB ram, 1 OS disk, 8 sata/pata 250G disks.
iozone -R -r16M -s 16g -i 0 -i 1 -i 2 -f
dd is with 8GB file, using conv=fsync where available.
Note on linux write performance: I suspect that it does something nasty with write-caching..

It is probably best to kill all spammers! I have been fighting spam for many years now. Why do they get to cause other people so much grieve and work?
.454 casul?
;)
Killing people in general is not right, but if you do it in a humane way, like shoot them through the head with a
It can't be hard to find volunteers for doing this. Shooting casul is a blast!
p.s. don't actually do this..
Cryptophone is a company that has been making phones like this for some time already.
They employ some of the smartest crypto people, use well-known algorithms and publish their sources so you can check them yourself.
Well, with minimal specs of a 500Mhz G4, it would almost have to be hardware. Even a little Mini is more than twice as fast as the minimal specs.
:(
The boxes are quite expensive though
They use hardware compression and provide a nice DV-stream to your computer. All it has to do is write it to disk.
Journaling? I'll take softupdates instead, thankyouverymuch.
