1What type of RAID are we talking about? You should edit your question instead of submitting a comment. What word is "aprt" suppose to be?– RamhoundCommented Dec 5, 2023 at 21:24

Hardware RAID generally only supports entire disks, not individual partitions. Software RAID can support partitions, but note that the throughput of the entire disk must be taken into account. For this reason, the details of your OS and other system details are necessary to begin giving you good answers.– music2myearCommented Dec 5, 2023 at 21:33

music2myear - whats the drawback to doing it software wise? My intentions is to have everything im working on say in Lightroom, on the 500GB ePCI drive . The 3x 500GB partitions would be where I archive or keep things long term. So not too much read and write , thats why i was hoping the remaining 2 x 1.5TB could be for regular use?– ManualphotogCommented Dec 5, 2023 at 21:56

3Why do you want to have a RAID array? doing it cheap can actually make your data more vulnerable to loss than single disk architectures. consider that if you did create a nine volume raid, if one of your 2TB disks fails, that would take down 4 of the RAID volumes, which is I believe beyond the rebuildable limit. its unlikely that just one partition on the disk would "go bad". cheap controllers can lose their logical volumes leading to a complete data loss in the worst case, without even suffering a single failed disk. consider your backups carefully. raid is not a replacement.– Frank ThomasCommented Dec 5, 2023 at 23:19

yes, i want to stripe the 500GB on each 2TB and then mirror to the barracuda 500gb . So the Barracude 500GB SATA is reliable , I then have 2X the read speed to the "original" 500GB (striped across two 2TB drives). My Question is can I then use the remain 3TB (or 6 x 500GB partitions - 3 on each 2TB drive) as normal HDD space. I dont intend to RAID all 9 partitions– ManualphotogCommented Dec 6, 2023 at 0:30

```python
def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. windows-7), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
