4-Port SATA 6Gb/s PCI Express RAID Controller Card with HyperDuo
HyperDuo TechnologyFeaturing HyperDuo technology, this SATA card provides automatic tiering of SSDs to take advantage of the performance of SSD storage, as well as the economy and high capacity of standard hard drives. The SSD/HDD combination in a single volume (up to 3 SSDs and 1 HDD), HyperDuo works unobtrusively in the background and moves frequently used files to the SSDs for improved data throughput - up to 80% of the performance of SSDs! This card supports port multiplication, allowing up to 7 SATA drives to be connected to a single port with a single cable (up to 4 drives via MP on one port, and one drive on each of the remaining 3 ports). In addition, the SATA controller card offers an efficient hardware RAID solution with native RAID (0, 1, 1+0) support. |

Purchased in duplicate several months apart, 1 in March 2021 (24 10 2022). Both cards were mounted in the same machine without any problem. I archive on 12 hard drives. I make copies and transfers with very satisfactory speeds of around 100 MB/s. To date, I have not had any file loss. So yes, I am very satisfied with the product and LDLC for the commercial part.
1. Cause of data loss
Installation (under windows 11) with 1 disk: ok (average performance but acceptable).
Adding a second and third disk: ok ... until I start writing to one of the disks -> all 3 are then corrupted.
2. Archaic update system
Archaic upgrade procedure unacceptable in 2022: a whole bootable key thing to do with a non-provided tool -> a trick thought up by last century technicians who never heard of user experience ....
I bought this card to set up a RAID 1 under Ubuntu 20.04 with 2 Seagate BarraCuda 8Tb HDD (ST8000DM004).
To configure the card, it is indicated to press ctrl + M, but it is for a QWERTY keyboard, for an AZERTY one, you have to press ctrl + ?.
Ubuntu recognises the hard drive perfectly like any other. I was able to install it without any problem except that the performance is mediocre. When the PC does nothing, Munin indicates a latency of 80ms. And a simple apt upgrade can take tens of minutes. As a result, I only use it to store backup files. It's impossible to run an OS, a VM or an application, it's much too slow. I rollback to my RAID 1 Mdadm and its average latency is under 1ms.
Allows you to bypass the limitation of Intel RAID controllers built into older motherboards for HDDs larger than 3Gb.
My server under WHS was able to reboot even though it was impossible to install directly on the motherboard RAID controller.
I ordered it at the end of November and received it on time as I often do with LDLC, I am very satisfied with it so far.
I have configured 2 ports in HyperDuo (1 SSD + 1 HDD) and for the moment everything is working properly and the performance is seriously improved.
No RAID configured as it is managed by the motherboard.
Conclusion: I recommend
In the same universe: raid card | raid controller | sata raid
