How to upgrade SSD in Lenovo ThinkCentre All in one PC
How to install and upgrade the hard drive with a SSD in a Lenovo Thinkcentre All In one (AIO) computer system. In this following video you can learn how to disassembly and replace hard disk with a SSD in Lenovo Thinkcentre PC
The basic difference between SSD and HDD is that solid state drives store data on integrated circuits and hard disk drives store magnetic data through spinning disks. They can be compared in terms of their speed, adaptability, technological modernity and user experience.
Hard disk drive is a commonly used storage disk that uses a moving read / write head to access data. It is a traditional type of storage unit used in computer devices.
Solid state drive, on the other hand, is a fast, motionless, and efficient secondary storage that stores data using flash memory.
SSD vs HDD – Comparative Analysis
Below is a tabular comparison between hard disk drive and solid state drive. Look at the points of difference and analyze which of the two is better and more suitable for use.| Difference Between SSD and HDD | |
| SSD | HDD |
| Full Form: Solid State Drive | Full Form: Hard Disk Drive |
| Movement: It is a solid drive and no movement occurs while its functioning | Movement: It is a moving drive and the hard disk spins when it is functioning |
| Speed: It has faster processing speed | Speed: The processing speed is low in comparison to SSD |
| Latency: It has low latency | Latency: It has high latency |
| I/O Operations: The number of Input/Output functions it can perform per second is higher in comparison to HDD | I/O Operations: The Input/Output operations which can be performed per second by HDD is lower |
| R/W Time: It has a shorter Read/Write time | R/W Time: It has a longer Read/Write time |
| Weight: In terms of weight, SSD is lighter in comparison to HDD. This is because no external mechanics or motor is attached to the drive | Weight: HDD is heavier |
| Sound: It does not produce any sound while it is in use | Sound: It make some sound because of the movement of components |
| Components: There are no moving parts. It only as a memory chip which stores data into integrated circuits | Components: HDD comprises moving components. It has one or more spinning disks that are placed on a spindle, which is motor-driven. These are called platters. Each platter is covered with a thin layer of magnetic substance |
| Power Consumption: No motion results in less use of electricity or power while using these | Power Consumption: Because of the spinning platters, more electricity and power is consumed |
| Cost: It is a modern storage drive and is costlier | Cost: It is a traditional storage drive and a bit cheaper in comparison to SSD |
| Size: It is smaller in size | Size: It is larger in size |
| Safety: SSD is more reliable in comparison to HDD | Safety: In case of any error in the drive, the entire HDD may crash and result in loss of data. This makes it less reliable |
All the points mentioned above, clearly state that although they are both storage devices and are used to boot the system, their features and functioning is different.
