True, plus, the laptop I currently have is from the same time frame but with a low end Core 2 duo and slightly better intel graphics. Honestly, I don't do any gaming so, the graphics is not a big deal. I've been thinking about putting in an SSD in it and pulling the disk drive to replace it with a decent sized hard drive.I'm pretty sure the connector is different between these iPods.
Assuming the price is right and you go for one of the later specs (Early 2008 is the last gen for the Black MacBooks) then it can still be a zippy little machine that will be capable of running Mountain Lion, don't expect too much of it though. A friend of mine is still running his Early 2008 with an SSD and 4GB of RAM (it can actually go up to 6GB) and he's very happy with it
Try making a small partition on your drive and install a fresh copy of the OS on that. Pain in the ass I know, but it should help diagnose whether or not this is a hardware or software issue.I do have time machine on, but then again my system is as up to date as I can make it. I might actually turn it off for a while to see if that makes any difference. It's an interesting proposition/fix, but certainly worth a go.
Earlier I booted up into the hardware test to see if it showed anything. It didn't. When I logged back in it took a good few minutes for it to find and connect the internet.
If it worsens over the next few weeks I'll trek up to Aberdeen or along to Glasgow to the Apple Shop. But I can only do that after final hand in.
Most desktop hard drives now write at around 120MB/s (not megabits, megabytes). For the case of current MBPs, iMacs and minis, the memory transfer rate is 10.666GBs. Under 100x faster. Not quite millions, but still bloody awful.Paging generally is moving stuff between memory and the hard drive.
Page in means stuff gets requested by some application that is not in memory, hence it is loaded from the hard drive. This is not bad in and of itself, since everything must eventually come from the hard drive.
Page out means memory content gets pushed to the hard drive to free up space (not to be confused with for example saving a file). This is "the bad one" if used excessively, mechanical hard drives are literally millions of times slower than memory while even SSDs still are hundreds of times slower.
The linear read/write speed is fairly irrelevant for the small blocks of data that likely are requested. What matters is the time it takes to position the head and wait for the data to come spinning round again. Even with modern HDDs this still takes 10ish milliseconds. Due to lack of moving parts in RAM this is reduced to a couple of nanoseconds. You'll find a factor of millions between those two.Most desktop hard drives now write at around 120MB/s (not megabits, megabytes).
