Rant: my 2011 MacBook booted faster from a $23 SSD than from the RAM upgrade I did first
Ordered the RAM first because everyone on forums said RAM was the bottleneck. 8GB kit arrived, installed it, boot time barely moved. Still 2 plus minutes to a usable desktop. Then a buddy who fixes old Macs in Portland shipped me a cheap 240GB SSD and a screwdriver for the swap. Same laptop, same OS, boots in about 25 seconds now. I keep reading that RAM matters more on these old Core 2 machines, but for what I do (browser, docs, some photos) the drive was the real fix. Was it the same for you, or did RAM end up mattering more once you already had an SSD in?
Yeah the RAM thing gets repeated so much online that people skip right past the drive. I went through the same mess on a 2009 white MacBook, dropped in 8GB and it booted about as slow as before, then a $30 Kingston SSD cut it from over two minutes down to like 20 seconds. The reason is that a spinning drive is the slowest part in the whole machine by a mile, so the CPU sits there waiting on reads no matter how much RAM you have. RAM helps more once you're already on an SSD and you're running a bunch of tabs or apps at the same time, but for raw boot speed the drive wins every time.
