    Hardrive configuration

    Hi,

    Is it a good idea to have Avid MediaComposer on SSD but Avid MediaFiles on a HDD 5400rpm to potentially work on 4k footage ?

    Thank you

    Absolutely not. 

    While MC will launch quicker from an SSD once launched you don't gain much. 

    However a single 5200rpm drive is barely enough for HD work.

    You would want something like 8 x 7200 spinning drives as RAID0 to get any sort of speed suitable for 4K

    Even a single SSD may not be fast enough you'd want striped SSDs

    Re: Hardrive configuration

    Ok, so is that ok with the config i mentionned to work with 4K proxies ?

    And, 5400rpm is not enough for HD too ?

    This is crazy Surprise

    Yes.

    No.

    You can pick up a good SSD for not much and get read speeds of close to 3GB/s. For 4k work this will be fine unless it's something like uncompressed 12bit or multiple streams of high quality 4k prores or something. Pat is correct, it's 2020 and there's no place for a 5400rpm drive in a modern setup apart from things like transport drives. Certainly not for media drives.

    Just do the maths on the datarates of the files you need tom playback. HD will vary from around 120 mbps to nearly 200mbps.

    to make 4K proxies you still need to read the camera original 4K files and they will range from 100mbps to 1gbps or higher

    Even proxy 4K files can be high datarate typically 150mbps or more.

    you get around 50mbps from a 5200rpm drive thats around 1/3 of what you need for proxy 4K files.

    Re: Hardrive configuration

    Thank you for your answer, i just found Pat solutions a little bit extreme ^^

    I totally agree 5400 is only for storage..

    I guess ill go full SSD

    Edit : i just do the maths and i'm not their best friend :D.. a 1hour footage Apple Prores 422HQ 4K straight from the cam would be 675Go or so ?

    Re: Hardrive configuration

    Not extreme at all, some of my edits are running 5-9 cam multicam 1080/2k projects and they are working from an 8bay Pegasus 2 RAID 5 setup with 7200rpm Toshiba enterprise drives and those things only just manage to play it back. They get less than 1000MB/s read speeds so I doubt they'd handle 4k multicam. 

    The CPU also makes a difference, my Macbook struggles to playback multicam 2k Prores LT even though my drives should theoretically be able to serve the data fast enough but the Mac Pro towers the editors use can hadle the same sequence on the same drives. 

    So I guess the takeaway is to make sure you also have a decently spec'd system, just having a fast SSD in a slow computer will not be enough.

    This whitepaper from Apple may be useful, it contains some data rate info on the various flavours of Prores.

    Re: Hardrive configuration

    I'm starting, so 9 multicams not for now :)

    I stated the use of those drives assuming these specs that i have :

    Ryzen 7 3700x

    32Go ram

    RTX 2060

    Re: Hardrive configuration

    The AMD CPU should ben ok. The RAM is OK (more is never bad) the RTX card is 6GB so should work for 4K (but not the nippiest 4K card)

    A boot drive SSD for apps is a no brainer.

    Its just you media drive that needs to be more even for 4K proxy work.
