Related Questions and Answers

Q: 1. Does this card provide ample power, not having a seperate power connection?

A: The RocketU provides the rated amount of power for any standard USB 3.1 Gen2 ports and devices. .

Q: 2. Using PCIe 3.0 on a PCIe 2.0 slot (bottle neck): Would there be any performance advantage over the PCIe 2.0 card?

A: PCIe 3.0 is double the speed of PCIe 2.0

Q: 3. Does this come with a half height / low profile BRACKET? The card looks like it's low profile, but the bracket doesn't!

A: Yes, the HP Dual TBT4 PCIe x4 Low-Profile Card's bracket is a low profile bracket.

Q: 4. Which ASMedia chip does this card use?

A: The manufacturer has not specified in the documentation, however the chip is similar, if not newer than the ASMedia ASM2142.

Q: 5. Will this card allow the PC to drive an Apple Display?

A: The HP Dual TBT4 PCIe x4 Low-Profile Card, (B&H # HE340L1AA), will allow Thunderbolt 4 devices to connect with a compatible HP workstation, however, the Apple Studio Display is not officially supported on Windows so I wouldn't recommend it for that.

Q: 6. Would this work in a Mac Pro 2010 tower to connect two NVMe drives via one PCIe slot? (in High Sierra which supports NVMe)

A: No, the QNAP Dual M.2 22110 / 2280 PCIe Gen2 x4 NVMe SSD Expansion Card B&H # QNQM22P244A is designed to work only with select QNAP NAS systems.

Q: 7. Is this device compatible with PCIE 2.0 slots?

A: The performance should be the same if you are not sending data to all four ports simultaneously. PCIe 2.0x4 = 2000 MB/s should allow near full performance from two ports simultaneously. If the card uses the ASM2142 (PCIe 3.0x2), then a single USB port can be 20% faster than a card that uses the ASM1142 (PCIe 2.0x2). The PCIe switch can convert the two PCIe 3.0x2 USB controllers to PCIe 2.0x4.

Q: 8. will this be compatible with hp z2 sff g9 board version 895D?

A: The HP Dual TBT4 PCIe x4 Low-Profile Card is not compatible with the HP Z2.

Q: 9. Will this work with an external Thunderbolt 3 Expansion chassis?

A: Yes, The AJA Corvid 88 card is supported with the Sonnet Echo Express SE IIIe Thunderbolt 3 Expansion Chassis for PCIe Cards BH #SOECEXSE3ET3 The Sonnet SE IIIe supports MAC/WIN/Linux (If installing on a New Mac M1 platform please check with AJA support to see if an M1 Driver has been released for the Corvid 88)

Q: 10. Does it come with the small bolt to secure the end of the drive?

A: Yes, a small screw, in a little bag taped to the side.
