Difference Between SSD And RAM
Difference Between Solid State Drive VS Random Access Memory
Following are some common differences between RAM VS SSD.
| Key | RAM | SSD |( Solid State Drive) |
| Definition | RAM stands for Random Access Memory. | SSD stands for solid-state drive. |
| Memory | RAM is also known as Primary Memory or Main Memory. | SSD is also known as Secondary Memory. |
| Component | RAM has no moving mechanical parts and consists of transistors etc. | SSD contains no moving mechanical parts |
| R/W Time | RAM is more faster than SSD | SSD is Less faster than RAM |
| Types | 1. FPM-(Fast page mode RAM)- 2. EDO RAM (Extended data operations read-only memory) 3. SDRAM (Single dynamic RAM) 4. RDRAM (Rambus RAM) 5. DDR (Double Data Rate) 6. DDR2 7. DDR3 8. DDR4 | 1. SATA SSD (SATA I, II, III) 2. M.2 SATA SSD 3. mSATA SSD 4. M.2 PCI-E SSD 5. M.2 NVMe SSD

| maxmimum sped | DDR4-1600 (or a 1,600MHz data rate) to DDR4-3200 (or a 3,200MHz data rate) | about 560MB/s |
| Maximum Capacity | 16.8 million terabytes | 120GB to 30.72TB |
| Cost | RAM is Much expensive as compared to SSD. | SSD is less expensive as compared to RAM. |
| Impact on Speed | RAM is low, computer will become slow. | SSD has less impact on computer speed. |
