[FUG-BR] SATA Externo ? Raid ?

[William David FUG-BR]

Ok você também pode usar o GEOM  GATE  + GEOM MIRROR pra  fazer
espelhamento em caso de de poucos dados e ter uma rede boa 100mb
disponivél.

no caso do  adaptador  que vc  falou
não seria o espelho com um RABICHO SATA que vai no SLOT PCI e no
conector SATA da placa mãe apenas ??

se for esse é GAMBIARRA. já pra  avisar.

The SATA standard also specifies a new power connector. Like the data
cable, it is wafer-based, but its wider 15-pin shape prevents
accidental misidentification and forced insertion of the wrong
connector type. Native SATA devices favor the SATA power-connector
over the old four-pin Molex connector (found on all PATA equipment),
although some SATA drives retain older 4-pin Molex. The SATA/power
connector has been criticized for its poor robustness—the thin plastic
tops of the connectors (see power connector picture at right) can
break due to shearing force when the user pulls the plug at a
non-orthogonal angle. The seemingly large number of pins are used to
supply three different voltages: 3.3 V, 5 V, and 12 V. Each voltage is
supplied by three pins ganged together, while ground is provided by
five pins. Pin 11 is used in newer drives for staggered spinup. The
supply pins are ganged together because the small pins by themselves
cannot supply sufficient current for some devices. One pin from each
of the three voltages is also used for hotplugging.

Adaptors are available to convert a 4-pin Molex connector to SATA
power connector. However, because the 4-pin Molex connectors do not
provide 3.3 V power, these adapters provide only 5 V and 12 V power
and leave the 3.3 V lines disconnected. This precludes the use of such
adapters with drives that require 3.3 V power. Understanding this,
drive manufacturers have largely left the 3.3 V power lines unused.
However, without 3.3 V power, the SATA device may not be able to
implement hotplugging as mentioned in the previous paragraph.

Você Precisa Saber Sobre o Serial ATA

Não recomendo usar este  Espelho

No windows pode até funcionar você desplugar o sata  desta maneira
amis no freebsd nao sei como o kernel vai se compertar.

No máximo você vai ganhar um Kernel Panic and have a nice day.  =o)
