The ATTO FastStream SC 5550E, 8250E and 8550E provide class leading performance and RAID protection in
an embeddable ATX form factor.
With the latest in storage connectivity technology, the
ATTO FastStream provides unprecedented flexibility
while adding RAID protection without compromising
performance.
ATTO FastStream Embeddable Storage Controllers
are high performance RAID storage devices which can
be seamlessly integrated into an ATX enclosure.
ATTO FastStream FC to SAS RAID controllers are
ideally suited for bandwidth intensive applications
such as digital film, video and audio as well as medical
imaging, digital prepress and disk to disk backup.
While RAID improves data accessibility and reliability
during normal operations, you still need a good
backup strategy for long-term protection of your data.
