SSD and SATA RAID

Question

RAID

The question has arisen - is it possible to combine hard drives into a mirror RAID array: SSD and SATA? If possible, won't a SATA hard drive slow down work with an SSD?

Answer 1

now there are good SSDs on a PCI-E board (with a built-in raid controller), they show slightly better results than SSDs with SATA

Answer 2

The mirror should start to slow down. Search Google for FlashCache, maybe it will come in handy for you.

Answer 3

Hmm ... in my opinion, even somewhere on Habré there was an article on the topic of combining SATA + SSD into RAID 1, in which everything was written on both screws, but reading was only with SSD. All this was raised on a software raid under Linux (apparently the hardware does not allow this). Unfortunately, I can't find the article yet.

Answer 4

Adaptec does hybrid raids, but it's read-only :(
It also has MaxIQcache

Answer 5

But isn't SATA a data transfer protocol, and in this case, the HDD is called SATA O_o. This refers to the same HDD and SSD. Why is everyone calling HDD SATA? Or am I misunderstanding?
