I am looking at purchasing the Areca ARC-1880i. Is there a big difference in preformance between this controller that has 512mb and the next cards up (1880ix's) with 2g or 4g of memory.
I don't have hard figures to substantiate this, but comparing the 1680 with 512 MB versus 2 GB, the difference is clearly noticeable. The difference between 2 and 4 GB is less clear with video material, since often clips are a lot larger than 4 GB. For preview files or media cache it will be more noticeable.
Personally, I would always opt for the iX version and the largest cache that fits in your budget.
Thanks for the reply Harm. I guess I'll be scratching up the difference in the price of the cards and get the 1880ix version.
