Hello,
I started this thread because I want a better understanding of SSD ( and other media ) writing and reading processes.
Are the writing speeds being limited by reading speeds ?
For example, I heard this example : let's say you have a hard drive/SSD with the writing speed of 300 MB/s and reading speed of 400 MB/s, and you have an USB stick with the writing speed of 100 MB/s and reading speed of 50 MB/s ( don't mind the sequence/random speed, it's just a basic example ). If you copy a file from the USB stick to the hard drive/SSD, the writing speed of the hard drive/SSD will be limited by the reading speed of the USB. Meaning the transfer will be made with 50 MB/s. ( the example can be used vice-versa, when coping from SSD/HDD to USB, and using the reading speed for the SSD/HDD in this case ).
1. Is this true ? Does the process of transfer the data implies using both writing speed of the hard drive/SSD and the reading speed of the USB, culminating into limiting the transfer to 50MB/s ?
Then, if this is true 2. does this also apply when transferring files from a HDD to a SSD ? meaning the transfer will be limited to the reading speed of the HDD ?
Other questions I have are related to operations that imply using the writing speed on a SSD, like saving a file on SSD ( from the same SSD ), or duplicating a file on SSD. 3. These 2 operations imply using only the writing speed of the SSD ? or also the reading speed is involved , thus limiting the operation to the reading speed of the SSD ?
4. Also, can you please give me some examples of reading and writing speed process on a SSD/HDD and how this works ( what speeds are used, how and when ) .
Please try to answer as best and specifically as you can to questions stated above : 1, 2 ,3 and 4.
Thank you very much.
Alex.
