StorSave™ with BBU
Technical Brief
System Reliability
The StorSave platform enhances controller
performance and increases SATA storage
system reliability by offering a unique set of
data protection and data recovery features,
combined with a BBU.

3ware uses both controller cache and disk
cache during SATA RAID operations, which
strengthens array performance during optimal
usage as well as degraded RAID operations
including faster rebuild times.

Disk Based Features
Dynamic sector repair increases drive
reliability with on-the-fly correction of drive
media errors in redundant arrays. Drives are
never degraded because of soft media errors.

Drive power-on reset detection reliably
detects unplanned drive power cycles through
ATA security commands and automatically
degrades a drive that may have potentially
lost data.

Extensive drive timeout recovery is an
intelligent timeout algorithm that maximizes
drive error recovery within server operating
system constraints thereby reducing transient
errors in drives and the controller. StorSave

BBU for Data Protection
The StorSave Platform supplies on-board
memory protection and sends power to the
cache memory module in the event of a system
power loss. It enables the use of controller and
drive write caching for best performance while
preventing data loss during critical events.

Secondary power loss support safeguards data
against on-site power interrupts and during
routine system power up. Missing array detection
eliminates silent data loss by retaining
unwritten data from an unusable array until
the user intervenes. Cached write data is not
