Testimonials

For a project requiring more than 80 custom servers, we needed a reliable U.2 SSD hot-swap solution. The HighPoint R1528D 8-port Gen4 Switch controller exceeded expectations, working flawlessly in both Windows and Linux—without requiring drivers. Performance was excellent, reaching the full 28GB/sec in our customer’s application.

HighPoint’s team was also fantastic—responsive and accommodating, even manufacturing additional cards for us, to a very tight deadline.

They delivered on time, making the process smooth and stress-free.

We look forward to working with HighPoint again as we transition over to PCIe Gen5 U.2 SSDs.
