Grading Cache - What?

[Alex Prohorushkin]

Hi Guys and Girls.

Who are using Cache-drive when Colorgrdading? What do you think about Fusion IO Drive2 / LSI Hydro Wrarp / Huawei ES3000 (3500) / or others. Maybe you used RaidCard + many SSD?

Alex.

I don't know if a raid card/sata drives is a good option for cache anymore, now that there are PCI-based drives in the market, and some motherboards directly support Raiding those drives as well.

Yes. 

I have it (Raid 5 (16x4Tb)^ speed is very good (up 2000 GB/s) BUT on this raid have  more MediaData. and I think that using this Raid for Cache maybe destroy it early end lifetime.

and I think that using special SSD set is good idea.

I have motherboard with dual M.2 slots and one is for os ssd with 250 gb 2000 read / 1500 write and 2 tb one for media and cache around 2000 / 2000 even tho on paper it should be faster.

Now there is ad on cards for some motherboards that stripe 4x M.2 for speed.
If needed then that would pretty nice.

I would consider ssd only for cache now as even the regular ones run 400-500 mb/sec.

Just my 2 cents.

I meant this but it needs asus board as it seems. I see in my bios selections for it.

Question about hard drives and still sequences: You can have performance issues If the frames are not written to the hard drive in a sequential order. That should not be an issue with SSD, right?

I would see it mostly as seek time and speed issue. If your drive or array has good speed or fast seek it should not be a problem. On ssd usually it is not the case as the nature of drive is different.
