TerraMaster this week introduced its first DAS featuring a Thunderbolt 3 interface. The D5 Thunderbolt 3 DAS with five bays is aimed at professionals who need a vast storage space attached directly to their PC. Using currently available hard drives, the D5 can store 80 TB of data, with peak sequential read speeds up to 1035 MB/s.

As the name suggests, the TerraMaster D5 Thunderbolt 3 can accommodate five 2.5-inch/3.5-inch hard drives or solid-state drives that can work in JBOD, RAID 0, RAID 1, RAID 5, and RAID 10 modes to provide various levels of performance and data protection capabilities. The DAS fully supports all RAID features one expects from a professional-grade storage device (see the table below) that has to ensure maximum reliability, predictable read/write speeds, and automatic RAID rebuild if needed.

Speaking performance, TerraMaster rates its D5 Thunderbolt 3 at up to 1035 MB/s read speed as well as up to 850 MB/s write speed. Such performance levels were measured by the manufacturer using a 5-disk SATA SSD array in RAID 0 mode. To ensure consistent performance and reliability, the DAS has two 80-mm fans.

As far as connectivity is concerned, the TerraMaster D5 Thunderbolt 3 DAS has two Thunderbolt 3 ports to daisy chain it with other TB3 devices as well as a DisplayPort 1.2 output.

Just like many other DAS, the D5 Thunderbolt 3 has a handle as many professionals need a lot of storage space while working outside of their home or office. The box itself weighs 2.3 kilograms, but when fully populated with high-capacity HDDs it will be considerably heavier.

TerraMaster D5 Thunderbolt 3 DAS will be available shortly. Pricing is unknown.

    Terramaster product page:

    "The D5 Thunderbolt 3 is equipped with a 40-Gbps lightning speed interface, and the read and write support attains speeds of up to 1,035 MB/s (test conditions: 5 SSDs, RAID 0 mode)"

    Yeah, '40-Gbps lightning speed interface'
    This performance is abysmal. 5 SATA SSD's in RAID0 should net 2-2.5GB/s, not "peak" at ~1GB/s.

    maybe that was mechanical drives? Reply

    It's horrifying to imagine how loud this box could bet with 5 mechanical drives and 2 fans in the back, all sitting right next to your keyboard, going full throttle on the I/O... I hope they include gratis earplugs with the hardware. Reply

    Depends a lot on the drive. Some drives you hardly notice, others sound like a tin can full of marbles. Reply

    Besides, the main point of getting SSDs is not to have 2.5GB/s instead of 1GB/s, it's to get the lowest possible latency. The cherry on the cake is silence and compactness.
    I wonder if many people will put SSDs in that though.

    With SATA ssd, that is about the level to expect. Reply

    I just bought a brand new BMW after having made $6375 this past one month and just over 12k last 4 week. This is the best and most financially rewarding job I’ve ever had. I actually started this few Weeks ago and almost immediately started to bring home minimum 74BUCKS p/h. I use details from this webpage... www.icash68.com Reply
