RAID Storage Power On/Off Controls
ARC-8050T3U RAID storage contains power On/Off controls on the controller. The power On/Off controls can turn ARC-8050T3U power in unison with the host computer power status for data integrity. It is advised that you use a proper power down procedure when you would like to power down your Mac and thunderbolt storage. If you attempt to power it down by pressing and holding the power button you run the risk of losing unsaved data and increase the chance of damaging hardware, more specifically the hard drive. Following improper power down, power up and restart sequence of a thunderbolt RAID storage and attached hosts will affect the normal functionality.
Smart Battery for the Integrity of the Cached Data
ARC-8050T3U-6/8/12 RAID storages have integrated caches for increasing performance. With corresponding protective mechanisms, the content of these unwritten cached data in the SDRAM would be lost when there is a complete AC power failure or a brief unexpected power outage. For that reason, a battery backup unit (BBU) protects the integrity of the cached data on ARC-8050T3U RAID storages by providing backup power. The battery backup module has built-in functionality to charge the battery pack automatically and to communicate battery status information to the RAID storage.
Actual data rates may vary depending on operating environment, RAID mode, RAID configuration, disk model and disk performance. The best performance is installed the SSDs and connect the device to a computer that supports Thunderbolt 3 at 40Gbps...... more detailed information
