external SSD fast enough for VFX?

hey guys

thinking of getting this -

https://www.sandisk.co.uk/home/ssd/extreme-portable-ssd

its speeds of up to 550 mb/s and my PC is USB 3.0, so is this fast enough to use my external SSD when using AE and other VFX programs? or cinema 4d/Blender etc

thanks for any info :)

This conversation over on Reddit https://www.reddit.com/r/AfterEffects/comments/9uqujb/external_ssd_just_for_cache_or_projects_also/ specifically references using an external as a cache drive, but it has everything you would want to know about USB 3.0 ports and sata speeds within the first couple of replies. The TL;DR is, if you're used to rendering from a sata drive, then the real world speeds you're going to see with a USB 3.0 port are going to be pretty much the same as the real world speeds you're seeing in your sata drives. If you're used to an NVMe drive, then you'll see a noticeable difference, in which case you'll probably want to shoot for a type-c/thunderbolt capable drive (which it doesn't sound like your system supports anyway).

Thanks for the reply, but an external SSD will work ok though for AE and Blender etc? I mean at least as fast as the internal SSD?

I wish I could give you better information than I already have. I wish this forum was ten times more active than it is. With the amount of people who love VCP and Andrew Kramer, you'd think this place would be a VFX and MoGraph Mecca, buzzing with activity.

Honestly, I would hit up Creative Cow, or even the Adobe forums, or Blender forums for that matter, all of those places are 5-100 times more active than this one and are likely to get you an informed reply from a person with real world experience regarding your question in relatively short order.

Which is not to say that you wont eventually get one here, it just might take a few weeks/months/years.

To try and help you with your speeds question though.

I think the biggest gains in render time that can be solved with hard drive/SSD optimization come from using an SSD (sounds like you have this covered), then having your assets and render output on different drives is next (can double render speeds from doing it all off one drive), after that is having a dedicated cache drive using the fastest drive possible.

The link I posted last time goes to a Reddit post that seems to indicate that a USB 3.0/3.1 connection should allow an external drive to read/write at sata speeds. I'm not totally sure if they are differentiating between SATA 3GB and 6GB ports in that or not.

If all you are asking is if it will work, yeah, sure, you can definitely render to and from an external SSD in AE and Blender, ymmv when it comes to render times though.

Sorry that's all I've got, I wish I could be more help.
