So I'm new to this computer stuff and I was wondering which makes a hard drive load data fast?
I'm not sure I understand the question. Do you mean how to prevent system lag or something? SSDs are leaps and bounds ahead of HDDs in terms of speed, so a very common configuration is to have a smaller (usually 250-500GB) SSD as the boot drive with the OS and most used applications and games on it, and a larger HDD for bulk storage that doesn't need to be accessed as frequently.
How quickly an application or data loads from a drive depends largely on what the application or data is. If your computer is bogged down with tons of processes, bloatware, or viruses that are eating up resources, things will generally run slow.
ohh ok i get it, it just confused me because people that rated the hard drives said things about loading data slow
Gotcha. Well HDDs do have different speeds, the most common consumer drives today run between 5400rpm and 7200rpm. Generally you find the slower speed drives applied to things like surveillance systems, where the data doesn't need to be accessed frequently so the slower speed isn't an issue and it's a bit cheaper.
Obviously if cost is a concern and you need a large amount of storage, a 5400rpm drive will work just fine, it'll just be a bit slower at sending data.
got it thanks!
There are usually two things to consider when talking about speed. The first being how fast it can move data at a 'sustained' rate. The second is how fast it can respond or how much latency. Just like your internet speed, one is the delay in response, the other is how fast it can push data.
So say you had a 100 Mbps internet connection. That comes out to be 12.5 megabytes a second. Your regular HDD can write to that just fine with no issue.
There is one more new thing. Optane memory (not the same as optane ssd) that goes in a M.2 slot and is supported starting with Kaby Lake. This is used as a ssd like cache for a regular HDD to speed it up. Still a bit of hype and no real benchmarks but it is releasing on the 24th in a few days so we should know a lot more soon. They come in 16gb and 32gb versions.
as another reference, usb 3.1 (generation 2) is 10 gigabits bandwidth (1250 MB/s) and thunderbolt 3 is 40gigabits (5 GB/s). Thunderbolt got support with Kaby Lake.
SSD = Expensive, small, fast. HDD = cheap, slow, alot of space.
