ATTO ThunderStream® Storage Controllers feature time-proven ATTO RAID technology and other proprietary technologies developed over the past 18 years to provide the highest performing shared storage solution in its class. ATTO ThunderStream® Storage Controllers integrate with disk drives to enable a small form factor, high performance RAID (0,1,5,6,10) array. In addition, SAS tape drives can easily be connected to Thunderbolt to provide access for backup software and LTFS tape applications.

US model: includes 110V power cord

EU model: includes CEE 7/7 (SHUKO) power cord and BS 1363 UK10 power cord


The ThunderStream® SC 4808D acts as an external Thunderbolt to SAS/SATA RAID adapter, connecting all-in-one systems and laptops to 6Gb/s SAS/SATA RAID storage devices.

The ThunderStream® features latency and disk management technologies which ensure optimal performance and minimal latency. ATTO's Advanced Data Streaming (ADS™) Technology manages latency by providing controlled acceleration for smooth data streaming. DriveAssure™ technology uses proprietary algorithms and user controls to prevent premature drive failures and slow downs. Combined, these technologies give users smooth, uninterrupted access to data with the highest available performance.
