Here is another with an older laptop with a WiFi bottleneck: Download a file from Google Drive = 2.5 Mb/sĪs you can see, the bottle neck there is your ISP connection. Laptop(newer with 802.11c) connected via WiFi to a router. Take this scenario below, which would be an average user setup: Note: there are some fiber ISPs now offering Gigabit connections, but those are extremely pricey and usually used by very bandwidth needy businesses. Meaning the fastest your download speed ever will be, in perfect circumstances, is 10MB/s (Megabytes). On the higher end of ISP packages, you can get 100Mb/s.

The network will always be the bottleneck.

There are 4^2 possible bottlenecks when downloading a file(s) from a server across the internet.Ģ) Physical Ethernet cable or WiFi connection to the routerĪnd then the same in reverse on the server side.Īs some comments have mentioned, it does not matter if you have a HDD connected via IDE at speeds of 5 MB/s, or a SSD that could write at crazy speeds of 10GB/s. When speaking in terms of a download speed, changing your disk drive will never have an effect on that. I was not really pleased by either answer here, so here we are. This mean your drive is about 600x faster than your network - the bottleneck argument is a moot point. Your internet, unless you live anywhere in Korea or lucky enough to live where there is Google or Comcast Fibre, it's probably around 100Mb/sec. If you didn't address any/all of these points, your download speed would have no change whatsoever.Īs for the bottlenecks addressed in the other answers, let me assure you that the data transfer rate of a SATA III interface is 6Gb/sec while your NIC (network interface card) at most will be 1Gb/sec.

The bandwidth the devices on your network is capable of (i.e.

The speed your router/modem is capable of.

Your download speed is governed by three things: To use a car analogy, you are asking why, given that you upgraded from a Toyota to a Porsche can you not load groceries into your trunk any faster. One has absolutely nothing to do with the other. Reviewer says SSD has very good write speed, but why does that not increase download speed?
