Solid disk in my Macbook Pro


Hi everybody,

Today i had a full day with I had Control-M V8 event but the most waited moment of the day it was now when I just installed my Solid Disk in my Macbook Pro.

1. This is my mac ready for his new solid HDD disk.

 

 

 

2. My mac in the middle of the operation… in this image we can admire my old disk 500 GB with 5200 RPM.

 

 

 

3. And the last one we can see the picture with my new solid disk, that by the way it´s working like a sparrow….so fast.

 

 

 

So in the end i would like to attach the differences between HDD & SDD.

 

Comparison chart

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 operationsper second) compared to SSD. SSD has lower latency, longer read/write times, and supports more IOPs (input output operationsper 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 insolid 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. Sodefragmentation 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.

 

And in here you have a stress test with 5 GB of data.
