Many users are in a quandary over the choice of either HDD or SDD. There is not a universal answer, as there are merits and demerits to both of them. The choice is heavily dependent on the user, their needs and budget.
Similarities between HDD and SDD:
- Both are used to store data.
- Both are used to boot the system.
- Both are I/O devices.
Differences between HDD and SDD :
| Parameter | HDD | SSD |
|---|---|---|
| Full Form | HDD stands for Hard Disk Drive. | SSD stands for Solid State Drive. |
| Components | HDD contains moving mechanical parts, like the arm. | SSD does not contains, mechanical parts, only electronical parts like ICs. |
| R/W Time | HDD has longer R/W time. | SSD has shorter R/W time.. |
| Latency | HDD has higher latency. | SSD has lower latency. |
| I/O operations per second | HDD supports fewer I/O operations per second. | SSD supports more I/O operations per second. |
| Fragmentation | HDD has fragmentation. | SSD do not has fragmentation. |
| Weight | HDD is heavier in weight. | SSD is lighter in weight. |
| Size | HDD is larger in size. | SSD is more compact in size. |
| Data Transfer | In HDD the data transfer is sequential. | In SSD the data transfer is random access. |
| Reliability | HDD is less reliable due to possibility of mechanical failure, like head crash and susceptibility to strong magnets. | SSD is more reliable. |
| Cost | HDD is cheaper per unit storage. | SSD is costlier per unit storage. |
| Time of Release | HDD is older and more traditional. | SSD is newer to use. |
| Noise | HDD can produce noise due to mechanical movements. | SSD does not produces noise. |
Though I also have SSD I have found that SSD’s are more likely to get bsod issues/system failure
recommend you exchange your Sata cable, or anything else between your motherboard and the SSD.
I’ve had multiple beefs with cables and enclosures.
