Seagate MACH.2 in Unraid.


Recommended Posts

Hi,

 

Seagate have launched a new disk technology they call MACH.2. Main USP is double transfer rate. More about MACH.2 here and here

 

In the articles I read Seagate have joined Microsoft on this. What are the chances this technology would be supported in Linux kernel? If so, what is needed in addition use it in Unraid?

which unlike the SAS models will present a single volume to the OS

If I understand this post correctly the first half of the disk is actuator 1 and the second half of the disk is actuator 2:

So even the SATA version is not compatible with Unraid (it works, but it won't enhance the performance). At first Limetech would need to create a complete different variant of the Parity creation / reading like "every second block is written/read to/from the second half of the disk".

 

And finally I don't think this is really worth the effort. A Samsung 8TB QVO is cheaper and combined with an 8TB NVMe as parity much faster in any aspect.
