SSD means solid-state drive or storage, which is secondary storage that uses integrated circuits. It stores all the data of the devices permanently and consistently using flash memory.
SSDs work very much faster, are silent, resistant to shocks and have low latency. It stores data in semiconductor cells. It was launched in 1991 by SanDisk.
Now it has a capacity of 250 GB to 1 TB. Western Digital Company also manufactures two types of SSDs, Blue and Green.
Key Takeaways
- WD Blue SSDs offer better overall performance, ideal for heavy multitasking and demanding applications.
- WD Green SSDs provide lower energy consumption and are suitable for lighter tasks and everyday use.
- WD Blue SSDs have higher storage capacities and longer warranty periods than WD Green SSDs.
