Salve a tutti! :)
Scrivo stavolta per risolvere un dubbio che mi è venuto da quando ho affiancato alla mia configurazione:
Primary Master: Maxtor 80GB 6L080J4
Secondary Master: Lite-On SOHW-1673S
Secondary Slave: Lite-On SOHD-16P9S
un secondo HD:
Primary Slave: Maxtor 80GB 6Y080L0
Ora, essendo il secondo HD più veloce del primo ma ancora in fase di "testing" da parte mia (lo ho recuperato da un PC dal quale se era collegato si inchiodava al detect :D) volevo chiedere a qualche "esperto" consigli sulla configurazione Primary/Secondary Master/Slave più performante :Prrr:
Considerate anche questo articolo che ha trovato mio fratello Punisher!:
Many tweakers forget one thing when they move their paging files to the second hard disk - only one PATA
(Parallel-ATA) device can be active at any one time on the same IDE channel.
Most users slave the second hard disk to the first hard disk on the primary IDE channel and put the
removable media drives (CD writers, DVD-ROM, etc.) on the secondary IDE channel. That is theoretically
sound practice but it actually negates the purpose of moving the paging file off the primary hard disk!
Because both hard disks are on the same IDE channel, they can't be active at the same time. So, there is no
way data can be read from both hard disks at the same time. In fact, because the secondary hard disk is
often slower and smaller than the primary hard disk, the performance of the paging file on the second hard
disk will actually be worse off.
So How Do We Make It Work?
The only way for this method to work is to put the first and second hard disks on separate IDE channels.
That means the first hard disk gets hooked up to the primary IDE channel and second hard disk gets the
secondary IDE channel. This allows both IDE channels can be active at the same time, delivering data from
both hard disks concurrently.
In addition, the second hard disk needs to be at least half as fast as the primary hard disk. This allows
the paging file on the second hard disk to be at least as fast as a paging file on the first hard disk.
Otherwise, the performance advantage accessing the paging file concurrently on a second hard disk will be
negated by the slower performance of the second hard disk.
Remember, if the first hard disk can serve data to and from both the application in use and the paging file
faster than the second hard disk can access the paging file alone, then it is pointless to maintain a
paging file on the second hard disk.
But if the second hard disk is more than half as fast as the first hard disk, then it would be advantageous
to move the paging file there because the paging file can then be accessed concurrently with data on the
first hard disk. In addition, the valuable outer tracks on the first hard disk will be freed up for use by
the operating system.
:doh:
Dunque cosa mi dite di fare?
Avevo pensato anche a una configurazione di questo tipo:
Primary Master: Maxtor 80GB 6Y080L0
Primary Slave: Lite-On SOHD-16P9S
Secondary Master: Maxtor 80GB 6L080J4
Secondary Slave: Lite-On SOHW-1673S
anche se devo ingegnarmi parecchio per riuscire a fare i collegamenti... :help:
