Hi
Hab SCSI Vs IDE UDMA133 gemessen.
Meine SCSI Platte hat komischwerweise nur maximal 43 MB/s bei hdparm -t und die IDE erstaunlicherweise maximal 54MB/s .
Das Ergebnis erstaunt mich einfach da die SCSI UW3 ist und naja 360MB/s schaffen sollte. Zwar ist der Kontroller nur für UW2 aber immerhin 80MB/s sollte er hinbekommen.
Das IDE nie auf seine 133MB/s kommt oder 2/3 davon ist ja bekannt aber das eine SCSI Platte so lahm ist?
Kann man sich auf die Ergebnise von hdparm -t verlassen?
Kennt jemand gute Festplatten Benchmarks (egal ob Windows oder Linux)?
hdparm -t komisches Ergebnis

Das es zwei geschwindigkeiten (extern/intern) gibt ist mir klar.
Mit -t misst man ja Lesezugriff und 43MB/s für ne SCSI Platte die 360MB/s bzw 80MB/s wegen Kontroller haben soll ist verdammt wenig
Intern (cache auf Platte) mit -T komm ich auf knapp 700MB/s da schlägt sie die IDE locker um 200MB/s
Was ist Bonnie? Haste mal Link + Erklärung?

bonnie++
http://freshmeat.net/projects/bonnie/
Bonnie++ is based on the Bonnie hard drive benchmark by Tim Bray. The most notable features that have been added are support for >2G of storage and testing operations involving thousands of files in a directory. This program is used by ReiserFS developers, but can be useful for anyone who wants to know how fast their hard drive or file system is. It now includes ZCAV in the package. This program tests the performance of different zones on the hard drive. ZCAV has been released separately before but will now only be released as part of the Bonnie++ suite.

bonnie is a classic file system and storage device benchmark. It tests for linear character-based and block-based reads and writes, and the rewrite pattern. It also does a seek test. While other benchmarks do more sophisticated tests, bonnie is a very reliable and portable program that is suitable for basic testing. Optionally, you can test the operations with direct I/O (O_DIRECT on Linux).
