Designed for modern 4K workflows and built using durable aluminum, the T4 20TB Thunderbolt 2 RAID Array (4 x 5TB) from CalDigit is an external RAID array that connects to your Windows or Mac system using one of its two Thunderbolt 2 ports at speeds up to 750 MB/s. Its second Thunderbolt 2 port may be used to connect multiple 4K devices such as monitors, I/O devices, and additional RAID solutions. The T4 has a total capacity of 20TB, which is configured as 4 x 5TB. While the storage in this RAID is comprised of 3.5" hard drives, its drive bays are also compatible with 2.5" drives.
The T4 supports a variety of RAID modes, including RAID 0, 1, 5, each of which offers performance, data redundancy, or a combination of both. For those who do not require a RAID, JBOD is also supported. Additionally, the T4 has a Hybrid RAID mode, allowing users to combine the unit into a RAID 0 or 1 with a JBOD, as well as format two drive bays as a RAID 0 or 1 and use the other two drive bays in the same way.
The CalDigit T4 20TB Thunderbolt 2 RAID Array (4 x 5TB) operates using 100-240 VAC at 2.0A and 50-60 Hz. It includes four drive modules, an AC adapter, an AC power cords, and two keys. The unit is also backwards compatible with Thunderbolt 10 Gb/s and is protected by a limited 5-year warranty, while the drives are protected by a limited 3-year warranty.
RAID 5 (Parity Striped
Users that require a combination of performance and protection should opt for RAID 5. RAID 5 offers single drive redundancy along with the performance of a striped set. In the event of a single drive failure, the data will remain intact and accessible, allowing the failed drive to be replaced
RAID 0 (Striped)
RAID 0 is designed for users that require maximum performance from their RAID array. A backup is highly recommend since RAID 0 does not offer any protection
RAID 1 is ideal for those who require a backup solution. Any data written to the RAID will be copied onto each of the four drives, resulting in four copies of the data
