Lots of really bad information in that article. SSDs performance, compared to spinners, is really so much faster that any slowdown that might be caused by the drive having to do some data juggling is trivial. I can connect the HDD in question to the computer via SATA > USB adapter and it works fine (Mac can even boot from it that way). I have a MacBook Pro 13' Mid 2010 that started to not see its internal SATA HDD. Spinners need a lot of space on them because they try to find a contiguous space to write the file, and if they cannot find that space, the heads have to move a lot more to spread the fragments of the file all around the discs. MacBook Pro 13' Mid 2010 is not seeing internal SATA HDD.
All those head moves take time, making the response time slow. That is why defragging a spinner can improve performance. I have a MacBook Pro 13' Mid 2010 that started to not see it's internal SATA HDD.
SSDs don't have to move any heads, don't really care about contiguous space because any address is equally accessible and fragmentation is meaningless. This question does not show any research effort it is unclear or not useful. In fact, SSDs deliberately spread data around for what is known as wear-levelling, as the memory locations can only be used for a certain (really high) limited number of times. Before The Purchase, Please Make Sure Both The MacBook Pro /Air/ iMac Models and The Logic Board Number (EMC) Match The Listing BIN Files Below-THIS NOT FOR KIDS.
So the data is spread around to keep from hitting any one address too many times.Īs a result of all that, SSDs actually don't need as much free space as do spinners. MacBook Pro Core 2 Duo 2.4 13 Mid-20.zip. Generally you need to leave 10% free on a spinner, but an SSD will function quite nicely all the way to about 3%, although I would leave a bit more on a boot drive if your RAM is heavily used so that swapping always has room on the drive.
