The Power of   

The Best Value value Thunderbolt™ 2 RAID 5 Storage for Creative Professionals.

  The T3 with Thunderbolt™ 2 is the groundbreaking successor to the original that brought outstanding performance to compact RAID storage. With a price point that starts at just under $500, RAID 5 technology, a 5 year warranty, and speeds of over 500MB/s, the T3 has become an integral part of professional 4K workflows. Traditional 2-bay RAID storage solutions cannot compete with the T3 in terms of raw performance, and do not feature the power of RAID 5 technology. The T3’s unique 3-bay design allowed CalDigit to integrate RAID 5 whilst at the same time keeping the starting price at under $500. This outstanding value makes it easier than ever for creative professionals to experience the power and protection that only RAID 5 can deliver.

  Featuring an industry leading 5 year warranty, one of CalDigit’s main objectives is to provide the best possible service to every one of our customers. Combined with our world-renowned customer support and impeccable attention to detail, every user knows that their data is in safe hands.

  While priced similarly to 2-bay RAID storage, the extra drive bay in the T3 allows for a level of flexibility that is not achievable by traditional 2-bay RAID storage. The T3 can be used with 3.5” HDDs and 2.5” SSDs (Solid State Drives). With SSDs in a RAID 0 it can achieve speeds of 1100MB/s, and with 3.5” HDDs it can achieve speeds of 580MB/s.

  Dual Thunderbolt™ 2 ports allows the device to integrate into a powerful 4K workflow that gives users the ability to daisy-chain a 4K monitor and any 4K capable devices.
Intel Thunderbolt

    The T3 features Thunderbolt™ 2 connectivity that enables transfer speeds up to 20Gb/s and supports 4K video streams. Daisy- chain up to six Thunderbolt™ 2 devices to create the ultimate 4K workflow.

    The T3 Thunderbolt™ 2 allows users to configure the device with either 3.5” HDDs for up to 15TB capacity or 2.5” SSDs for up to 3TB in capacity. Users can also mix and match multiple drive configurations allowing for a combination of 3.5” HDDs and SSDs in the same device. For example users could use an SSD as a scratch disk for their work and use the 3.5” HDDs for data back-up.

The T3 offers incredible value from a performance to cost ratio. It provides faster performance than dual bay RAID 0, 1 & JBOD devices with either 3.5” HDDs or 2.5” SSDs installed. As well as all this great value the T3 supports RAID 5, which is not possible with 2-bay storage devices.

*CALDIGIT Inc. (CALDIGIT) warrants that all CALDIGIT Inc. manufactured equipment will be free of any defect in materials or workmanship for the period of FIVE (5) years. Warranty begins from the date of shipment from a CALDIGIT facility or Authorized Dealer invoice date. The warranty is extended to customers and applies to all CALDIGIT manufactured equipment purchased, installed, and used for the purpose for which such equipment was originally designed. The above warranties cover only defects arising under normal use and do not include malfunctions or failures resulting from misuse, abuse, neglect, alteration, problems with electrical power, usage not in accordance with product instructions, acts of nature, or improper installation or repairs made by anyone other than CALDIGIT or a CALDIGIT authorized third-party service provider. CALDIGIT reserves the right to substitute functionally equivalent new or serviceable used parts. THREE (3) Years warranty on Hard Disk Drives and/or Solid State Drives.

    Constructed from rugged die-cast aluminum offering durability, rigidity, and superior thermal conductivity. The T3 is engineered with premium components that surpass inferior materials such as plastic and sheet metal used by competing products.

    Every professional external RAID storage solution needs powerful software to manage that RAID device. The CalDigit Drive Utility completely runs and configures the CalDigit T3. This powerful software provides vital drive information, RAID management, event notifications, email notifications, event logs, and disk benchmark tests. The CalDigit Drive Utility can also be used to monitor multiple T3 units and CalDigit’s other Thunderbolt™ RAID storage solutions.

    The T3 offers incredible value from a performance to cost ratio. It provides faster performance than dual bay RAID 0, 1 & JBOD devices with either 3.5” HDDs or 2.5” SSDs installed.
*Actual data rates may vary depending on operating environment and other factors, such as RAID mode, RAID configuration, and disk capacity.

     Configure the T3 into RAID 0 for incredible performance, RAID 1 for maximum protection, or RAID 5 for a balance of performance and protection. The 3-bay design also allows any combination of RAID 0, or 1 and JBOD.

RAID 0 (Striped)
RAID 0 is ideal 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 (Mirrored)
RAID 1 is ideal for those who require a backup solution. Any data written to the RAID will be copied onto each of the three drives, resulting in three copies of data.
RAID 5 is ideal for users who need great performance whilst at the same time having single drive redundancy for their data.

Mode Minimum Disks Capacity Protection Performance
RAID 0 2 ★★★ ★★★
RAID 1 2 ★★★
RAID 5 3 ★★ ★★ ★★

    Traditional dual bay RAID devices are only capable of being configured as a RAID 0 or 1. The additional HDD in the T3 allows users the flexibility of combining a RAID 0 or 1 with a third JBOD drive. This versatility opens up many possibilities for any user to tailor their storage to their needs, instead of the other way around. Configure the T3 with one SSD into a JBOD, and pair that with two HDDs in a RAID 1 for the ultimate all-in-one solution.

    The perfect balance between a compact dual drive RAID and a powerful quad bay. The three bay design offers stunning performance in a compact package.

    The next generation T3 features the latest Thunderbolt™ 2 technology for use with Thunderbolt™ 2 equipped Macs. It is also backwards compatible with computers equipped with the original Thunderbolt™ interface. Thunderbolt™ 2 takes the original Thunderbolt™ 1's dual 10Gb/s bi-directional channels and combines them into a single 20Gb/s bi-directional channel.
