Hello friends

I want to know if exists a command that indicates the speed between the HDD/SSD and mainboard.

Thank You

What do you exactly mean by ssd/hdd and the mainboard?

If you mean read/write speeds then I think Gnome Disks gives the option of checking read write speeds

Thanks for the reply

I want to know the speed of data transfer between a HDD or SSD and the
mainboard.

Goal:

I want to do a comparison of speeds against

  • Thunderbolt 3/4/5 if is connected through a docking station with a M.2 NvME PCIe

versus

  • SSD (HDD) and the mainboard

Thus I want to know how viable would be install Linux in a secondary SSD through a docking station with Thunderbolt.

I know thunderbolt has the following values about speed

  • Thunderbolt 1: 10 Gbit/s per channel, or 20 Gbit/s total
  • Thunderbolt 2: 20 Gbit/s total
  • Thunderbolt 3 and 4: 40 Gbit/s bidirectional
  • Thunderbolt 5: 80 Gbit/s bidirectional

So, If the difference is really huge thus I must consider use dual boot but it takes space in the primary disk.

Something like this ?

You probably need about 100Gb for the root filesystem, including a small home directory. I would put it on the internal disk.
You could put any large data filesystem on the external disk, and mount it.
You could share the data filesystem between two distros in a dual boot… they can also share a swap space… they can not share home directories.

Thanks to all for the replies

Thanks for the tip. It is now in my consideration that tool, but I meant a command in Linux, something like the dmidecode command

You probably need about 100Gb for the root filesystem, including a small home directory. I would put it on the internal disk.

I thought for a simple scenario 500 GB for each OS.

You could put any large data filesystem on the external disk, and mount it.

Now I see your point

You could share the data filesystem between two distros in a dual boot… they can also share a swap space… they can not share home directories.

I did do dual boot in my PC Desktops in 2008-2010 I used

  • C:
  • D:
  • Swap
  • /home

Thus was possible mount D (Fat32 - even in NTFS) in Linux to be shared between the OS’ … I did this approach up to Fedora Core 17 (In that days did not exist neither the Workstation nor server Terms
