![]() I replaced the 7200 rpm hard drive in an old MacBook Pro with an SSD and the boot time-from a cold start to the point where I could begin using the computer-dropped from over one minute to under 10 seconds. One of the first things you’ll notice is your computer’s startup time. It’s hard to overstate the speed advantage of SSDs compared to a hard drive, although there are some areas where the difference is much more pronounced than others. Hard drives have served us well, but compared to SSD’s they are slow, inefficient and delicate. Besides speed, the amount of physical space required for an SSD is much smaller than a hard drive-in some cases, the SSD isn’t even in a “drive” form factor, but instead looks like a stick of RAM that fits in a slot on the motherboard. ![]() Flash memory is used to store data, making the process of reading and writing significantly faster. Think of an SSD like a turntable playing a vinyl record and you have the idea, only instead of rotating at 33 or 45 rpm, even a relatively slow laptop hard drive’s platter spins at 5400 rpm! Data is written in blocks that get fragmented as the drive fills up, and that means the read/write head is constantly zooming back and forth.Īs the name implies, SSD technology is “solid” in the sense that there are no moving parts. A magnetic platter spins rapidly inside a housing, while an arm-mounted read/write head moves across it to read or write data. Hard drive technology is a precisely coordinated series of moving parts. Solid state storage has several distinct advantages over the hard drives that have traditionally been used for PC storage.
