Upgrading your MacBook iMac with a Solid State Drive (SSD) can make it feel like brand new again, probably faster than it ever was! Not only do you get much better performance, but longer battery life, increased reliability, and less noise as well
MacBook iMac Too Slow?
Even brand new computers can sometimes feel like they are slower than your previous one! Even in 2019, over half of brand new computers still ship with hard drives – technology straight from the 1980s!
Older computers almost always have hard drives in them – and that’s the major bottleneck. If you consider replacing your computer due to its performance, we have good news for you!
Upgrading it with a Solid State Drive (SSD) can make your computer feel like brand new again, probably even faster than it ever was! Your computer will work exactly the same way but everything will start and load several times quicker.
Hard Drives vs Solid State Drives
Properties HDD SSD
Stands for Hard Disk Drive Solid State Drive
Speed HDD has higher latency, longer read/write times, and supports fewer IOPs (input output operations per second) compared to SSD. SSD has lower latency, faster read/writes, and supports more IOPs (input output operations per second) compared to HDD.
Heat, Electricity, Noise Hard disk drives use more electricity to rotate the platters, generating heat and noise. Since no such rotation is needed in solid state drives, they use less power and do not generate heat or noise.
Defragmentation The performance of HDD drives worsens due to fragmentation; therefore, they need to be periodically defragmented. SSD drive performance is not impacted by fragmentation. So defragmentation is not necessary.
Components HDD contains moving parts – a motor-driven spindle that holds one or more flat circular disks (called platters) coated with a thin layer of magnetic material. Read-and-write heads are positioned on top of the disks; all this is encased in a metal cas SSD has no moving parts; it is essentially a memory chip. It is interconnected, integrated circuits (ICs) with an interface connector. There are three basic components – controller, cache and capacitor.
Weight HDDs are heavier than SSD drives. SSD drives are lighter than HDD drives because they do not have the rotating disks, spindle and motor.
Dealing with vibration The moving parts of HDDs make them susceptible to crashes and damage due to vibration. SSD drives can withstand vibration up to 2000Hz, which is much more than HDD.
