I have a LSI 1GB 9270-8i and all the features enabled to make Raid fast. When I bent the battery cable and ordered a replacement, the newer 2/4/8GB controllers on the market caught my eye. Let’s say I have 4 x 10TB enterprise 7200 rpm drives and want to measure performance of Raid5 and we can test Raid10 and why not Raid0 for good measure too. Will it matter much to upgrade to a larger cache controller? Yes I backup the whole thing to another computer. I’m mostly copying movies or games to the virtual disk, have my Steam library on there, do a little photo editing like sorting for favorites and minor touchups, nothing too crazy like a database or major movie production or anything but just want to know is it worthwhile to upgrade in this scenario? Will I go wow the next time I copy a TB over or will I see no real added benefit?

    Next time you copy over 1TB you might start off with “Wow” before hitting the “Yawn”.

    Caching is good until you fill the cache and then everything drops back to normal.

    But with smaller files you probably will notice a difference

      This is likely going to be one of those FOMO purchases. I’m genuinely curious to grab one of these 4 gigabyte refurbs that only work connected to a raid expander but they’re selling super cheap because of that fact. It would be preferable to know if any actual improvement could be expected. I had 512 GB of Cachecade on here at one time but games would open ridiculously slow, doesn’t seem to do well for desktop usage. Throwing games on an SSD is much faster of course but I’m trying to squeeze some oomph out of these 4 drives.
