With a 16-port storage bays and three PCIe slots, the NA333TB3 can be used as an enterprise RAID storage solution with room for networking cards or other devices as well.
The 16-bay chassis features hot-swappable drive trays that support SSD/2.5" HDD and 3.5" hard drives. When each bay is outfitted with a 10TB HDD, the NA333TB3 is capable of presenting a massive total usable storage pool of 160TB in RAID0. In addition, its three internal PCIe 3.0 slots allows organizations to expand the NA333TB3 via a range of specialty PCIe cards. Though the RAID adapter card will need to take up one of those spots, users can still add two additional cards such as video capture, video transcoding, audio accelerator, or a network card.
Using the Thunderbolt 3 interface, Netstor claims the NA333TB3 can offer bandwidth speeds up to 2.75GB/s.

Design and Build
The NA333TB3 is of a 3U form factor that sports a rugged, cold-rolled steel housing chassis. All drive trays are accessed from the front panel, which takes up the vast majority of this heavy-duty storage solution. Each has its own individual tray lock, and HDD power and HDD status LED.
Both sides of the NA333TB3 have a sturdy handle to help move the device into a rack, while the top right is home to the mute button as well as a fan status and temperature LEDs. There is also ventilation that runs along the top center of the front panel next to the Netstor branding.
Turning around to the back side shows the two power supplies on the left, each of which has its own dual fans, power switch, and power cord receptacle. At the center is the 90x90mm hot-swappable cooling fan next to the two Thunderbolt 3 connectors.
Opening up the top cover shows the Thunderbolt 3 target card, which comes already installed. The three remaining slots include the PCIe slot #2(open-type; supports PCIe card x16/x8/x4/x1). Netstor recommends using the RAID card in this particular one since it’s the closest to HDD backplane connectors. The two remaining slots 3 and 4 support closed type PCIe x8/x4/x1 and open-type PCIe x16/x8/x4/x1, respectively.
Performance
To test the NA333TB3, we connected it to the most recent HP ZBook 15 G4 workstation through an Adaptec RAID 81605ZQ RAID card. We ran RAID0 across 16 x Toshiba HK3R2 SSDs. We also tested its performance via the RD400 M.2 SSD, which was installed inside its own M.2 sled.
Looking at our large file 2MB sequential performance, the NA333TB3 was able to reach 2,506MB/s read and 2,457MB/s write when populated with the Toshiba SSDs in the drive bays. As expected, the RD400 m.2 SSD did well with 1,252.90MB/s read along with equally fast write performance at 1,228.56MB/s.
In random 2MB performance, the NA333TB3 continued to show solid performance. When testing the transfer speeds of the Netstore device via the drive bays with the Toshiba HK3R2 SSDs, we saw 2,505MB/s read and 2,465MB/s write. The M.2 drive showed 1,252.36MB/s read and 1,232.341083MB/s write.
Conclusion
The Netstor NA333TB3 is a 16-bay DAS solution that features Thunderbolt 3 connectivity for some pretty speedy performance, as demonstrated above, along with a massive storage pool of up to 160TB. This makes it ideal for businesses and power users that require fast, locally attached storage. Netstor has also made this a highly versatile device, as it supports pretty much all brands and models of RAID cards. The extra PCIe slots give users a ton of options to work with as well.
We tested the NA333TB3 in a variety of different configurations connected to a HP ZBook 15 G4. Leveraging the 16 drive bays connected to an Adaptec SAS3 RAID card, we recorded some great transfer speeds, with 2,506MB/s read and 2,457MB/s write when populated with enterprise Toshiba SSDs. Results made it clear that (as expected) a M.2 expansion slot adds a ton of flexibility and would certainly be a viable option to store hot data on. For example, when we equipped the NA333TB3 with an RD400 M.2 SSD, we recorded transfer read and write speeds with 1,252.90MB/s and 1,228.56MB/s, respectively, during our 2MB sequential test.
Overall the Netstor NA333TB3 gives users some lots of choice when it comes to expanding storage on devices with USB-C connectivity. This could include notebooks, such as the HP ZBook 15 we tested, or workstations that don't have the room to fit additional storage. To that end the NA333TB3 offered plenty of flexibility as well as excellent performance potential.
Bottom Line
The flexible and powerful Netstor NA333TB3 is ideal for organizations with demanding use cases while offering massive potential storage pool of 160GB.
