Hi.

Unraid Wiki says "never ever even think about using ssd drives as data/parity" ;)))

OK OK but:

 

1. I assume that above applies to consumer grade SSD's, not something like this right: https://www.samsung.com/semiconductor/ssd/enterprise-ssd/MZILT1T9HBJR-00007/ ?

 

2. If answer to Q1 is "yes you can" so what kind of parity drive will be recommended? One of these 1,92Tb SAS SSDs or maybe just normal ~2Tb SSD or even traditional ~2Tb HDD?

 

3. Last but not least if answer to Q1 is "yes you can" so do i need any cache drive?

 

Thanks

This is old, you can use SSDs, just be aware that they can't be trimmed for now, so write performance might degrade over time, especially on cheaper models.

Thanks.

And what with questions 2 and 3?

I use normal consumer SSDs for my small array, Samsung 860 EVO for data and a WD Black NVMe device for parity, most other users I've seen using SSDs also use consumer models.

 

Cache device is always optional.
