The 12big Rack Serial supports SES (SCSI Enclosure Services) 2.0, which allows you to closely monitor the status of your disks and enclosure, so you can work confidently with the knowledge that your 12big is always operating under the best conditions. The SES 2.0 protocol works with you to warn in case of component failure. To ensure the best quality, only Enterprise Class disks are used in the LaCie 12big Rack Serial, meaning that you can fully rely on the system to protect your data. They have been developed with rotational vibration resistance technology, helping them to be even more reliable and robust. 100% of the enclosures and 100% of the disks are tested before being sent.
