The data-access time of drives can vary widely depending on the type of drive (HDD, SSD, etc.) and its specifications. Here's a general comparison of typical data-access times for different types of storage:
-
Hard Disk Drives (HDDs): Usually have access times around 5 to 15 milliseconds (5,000 to 15,000 microseconds).
-
Solid State Drives (SSDs): Access times can be around 0.1 to 0.5 milliseconds (100 to 500 microseconds).
-
NVMe SSDs: These are faster SSDs that can have access times in the range of 10 to 30 microseconds.
Given that your memory data-access time is 60 nanoseconds, no traditional drive technology (like HDDs or even regular SSDs) would outperform that speed in terms of access time. The fastest access times for storage being close to 100 microseconds (for high-end SSDs) are still significantly slower than 60 nanoseconds.
Thus, to answer your question directly: in general, there is no conventional drive technology with a faster data-access time than the 60 nanoseconds you've specified for memory. Access times in storage devices typically lag significantly behind that of memory (RAM).
