I order a new dedicated server from a provider. The server has 2 Toshiba disks and the disk peformance is very slow. It's 3-4 times slower than other disks (for example Seagate).
I had the same problem in a production server (I notice it after I put it in production) and ask the datacenter to replace one disk with different model, I rebuild RAID-1, then replace the second disk and I rebuild the RAID-1. And the issue resolved.
It shows these disks as UDMA5 but other disks with good speed show UDMA6.
Here is the dmesg output:
What could be the problem with the Toshiba disks?
