Technology companies love to showcase their performance specs. However, many vendors will only show their maximum performance. What truly matters to the customer, is the sustained performance. Here's why.
The problem with sustained versus burst performance, if you're not working off of this sustained performance then at some point whether you like it or not, you will be. If you've got a few users that might not be a big deal. You might benefit a lot from a small cache. It might work great.
If you've got more than a few users, you know that it's going to come and go depending on who's doing what. The speeds are going to be pretty variable and if you've got a lot, even if you have a few users, if you have a lot of data or big files if you're working at 5K-6K or something like that you go through cache fast.
So there's a lot of different stuff to keep in mind on that but when it comes to video stuff we really want to focus on sustained performance because we just don't know how much data is going to be coming and going.
