I have a server with 1 gbps connection (which is ~125 MB/s). The server has normal mechanical Hard disk drives. Afaik their speed limit is also around 120 MB/s. For instance, if I download a file from a very fast server and reach my maximum speed, it would download at around ~100 MB/s which fits well since that's the maximum of my connection + the drive can't write faster than this(afaik).
I was wondering if we upgrade to a 10 gbps connection, which means ~1GB/s up/down speed. Am I going to feel any difference? for example if I download from some fast server like google drive, as far as I understand the concept, I still won't be able to download faster than ~120 MB/second unless I replace the normal HDD with SSD or SAS, since the normal drive can't withstand a faster speed, am I wrong?
P.S: the HDD I'm talking about is 7200rpm Thanks in advance
1In your first three sentences, you seem to understand that it's already bottle necked with your 1 Gbps connection. Yes, a 7200 RPM will absolutely bottleneck 10 Gbps, and is already a bottleneck with 1 Gbps. – DrZoo – 2019-02-05T17:15:51.403
A conventional hard drive is usually a bottleneck in a file server. That is why the OS allocates such a large amount of RAM to the file cache in attempt to minimize the need to access it. This helps but cannot eliminate the problem. – LMiller7 – 2019-02-05T18:20:45.260
