Actually I have this kind of configuration:

  • 4 HDDs and 1 SSD linked via SATA
  • 1 SSD (8GB) linked via eSATA

RAID 10 of the 4 HDD partitioned as [ / ] and [ swap ]

SSD1 as [ /boot]

SSD as [swap]


Now for my new configuration I am thinking as something like this:

  • [/boot] SSD1
  • [/] md10 [ HDD1:HDD2 as RAID 0 → HDD3:HDD4 as RAID1 ]
  • [/tmp, swap0] md0 [ partitions of HDD1:HDD2]
  • [swap0] SSD2 (8GB via eSATA)

My initial idea was to use all the 4 HDDs as [/tmp] and [swap] but then I thought that the 2 HDDs (3 and 4) working as redundancy could create slow downs.

But setting up the 2 partitions of the 2 HDDs (1 and 2), actually working as RAID 0 of the md10, as RAID0 too, it shouldn't create bottlenecks.

Do you agree?

Having your boot partition on an external drive is asking for disaster. Don't do it. Just make a primary boot partition on the root drive.

The SSD will be faster and more responsive than the RAID 10, as it sounds like this is for a workstation use rather than server.

I'd honestly do something like:

  • SATA SSD - /boot + /

  • RAID 10 HDD - /home/<user>/

  • eSATA SSD - Use for a side project. More != better.
