The RocketRAID 642L 4-Port SATA 6 Gbps RAID Host Bus Adapter from HighPoint is ideal for desktop PCs and workstations. This second generation SATA 6 Gbps host controller utilizes the PCIe 2.0 host bus interface, HighPoint's industry-proven RAID engine and supports a wide-range of single-disk and RAID configurations including 0, 1, 5, 10 and JBOD.

The RocketRAID 642L HBA is fully backwards compatible with SATA 3 Gbps devices, PCIe 1.0 and 2.0 motherboards. Additionally, it is compliant with major operating systems including Windows 8 and Mac OS X Mountain Lion.

The RocketRAID 642L HBA features both internal and external 6 Gbps SATA ports and is an ideal HBA platform for applications that require built-in storage expansion capabilities. The internal ports provide direct connections for up to 2 SATA hard drives and solid state drives, while the external ports are capable of supporting an additional 10 SATA devices when used in conjunction with port-multiplier capable storage enclosures.

The compact PCB design, low-profile form factor and industry-standard port connectors make any storage upgrade, integration or expansion project a snap.

PCIe 2.0 Host Interface    2 x eSATA & 2 x SATA Ports    RAID 0, 1, 5, 10 & JBOD    Supports Up to 4 SATA Hard Drives    Designed for Mac and PC

The RocketRAID 600 series Host Bus Adapter directly supports up to 4 SATA hard drives and solid state drives, and 16TB of storage.

Related Questions and Answers

Q: 1. Will this drive support two disks in a raid setup?

A: I'm doing that right now. Have three sets of disks, 1TB SATA, 500GB SATA and 256GB SSDD. Works great. Both the Mac's OS solution for soft raid (established in DiskUtilities) and the commercial SoftRaid software did the trick.

Q: 2. Could this work for other 60w led lights?

A: As long as the barrel size of the Nanlite V-Mount Battery Adapter matches the 60w led light plug it will work.

Q: 3. 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: 4. Does this work with El Capitan? Is anyone using it with 6TB drives? Does it allow for easy mounting and unmounting of drives while there are two hardrives connected? any crash issues or kernel panic warnings I should know about?

A: I have El Capitan running on a SSD in the dock, no problems, crashes, etc.

Q: 5. 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: 6. Can each thunderbolt be used to connect a different host computer so each can access drives at the same time?

A: The two ports are for daisy chaining devices but only one computer can be attached to a DAS at once.

Q: 7. Can you use multiple RS5212 at the same time, on a thunderbolt hub, or from two separate thunderbolt connectors on my MacBookPro? (Use two/three of these to access 4/6 drives at the same time)

A: You can not daisy chain them. but if you use separate connections from MBP, it will see 4/6 drives at the same time.

Q: 8. is the raid hardware or software?

A: It has a hardware RAID controller.

Q: 9. My laptop only has usb type C, it does not have thunderbolt, this device can be used to connect it to my laptop convert the port into a thunderbolt to connect eGPU?

A: No the computer must have Thunderbolt 3. And if the computer has Thunderbolt 3 this is not used as a chassis for an eGPU but rather port expansion.

Q: 10. is this product compatible with mac studio 2023, sequia 15.0 in raid 0?

A: Yes, the HighPoint RocketStor 8-Bay Thunderbolt 3 RAID Enclosure is compatible with a 2023 Mac Studio on macOS Sequoia in a RAID 0 configuration.
