以下是Redis和RDBMS之间的差异列表：
| Redis | RDBMS |
|---|---|
| Redis stores everything in primary memory. | RDBMS stores everything in secondary memory. |
| In Redis, Read and Write operations are extremely fast because of storing data in primary memory. | In RDBMS, Read and Write operations are slow because of storing data in secondary memory. |
| Primary memory is in lesser in size and much expensive than secondary so, Redis cannot store large files or binary data. | Secondary memory is in abundant in size and cheap than primary memory so, RDBMS can easily deal with these type of files. |
| Redis is used only to store those small textual information which needs to be accessed, modified and inserted at a very fast rate. If you try to write bulk data more than the available memory then you will receive errors. |
RDBMS can hold large data which has less frequently usage and not required to be very fast. |
