Jime234 Posted August 18, 2021 Share Posted August 18, 2021 Hi, I have a 5400 rpm 500 GB laptop hdd. I tested its speed with crystal disk mark in the laptop and the speeds were about 20 mbps. But when I tested the same hdd with a usb enclosure, the speeds were about 90 mbps! how can there be such a huge difference? Am I missing some drivers or something?

J.D Posted August 18, 2021 Share Posted August 18, 2021 Not sure what you are measuring, Disk speed or 'Transfer / Copy Speed' ? Have you reported that ^^ the correct way round ? For sure, SATA is many times faster than a USB2 or 3 port connection - maybe your AV was running or some other program . Jime234 1 Quote Link to comment Share on other sites More sharing options...
DLord Posted August 19, 2021 Share Posted August 19, 2021 Either you have made a mistake in speed test or something is wrong with your SATA driver/setup. As mentioned above, SATA transfer rate is way higher than any USB port protocol/connection. Jime234 1 Quote Link to comment Share on other sites More sharing options...

I noticed it when I was copying files from the system to the usb enclosure hdd. Then I tested it with CrystalDiskMark8 as usual to make sure. How can I go wrong with my SATA setup? Is there a chance that I actually did not install a SATA driver software of some sorts? Quote Link to comment Share on other sites More sharing options...
neofita Posted August 19, 2021 Share Posted August 19, 2021 check BIOS for HDD mode (it must be SATA and not IDE) Jime234 1 Quote Link to comment Share on other sites More sharing options...

Modern laptops over the past 5-6 years use a SATA 6 gigabyte driver, before that they were SATA 3 - look in Device Manager, tick "show hidden devices" at top under view, then look down the list for 'Storage Controllers and click it - I'm assuming of course that you have an Intel CPU and if so likely to have an Intel Storage Controller driver Jime234 1 Quote Link to comment Share on other sites More sharing options...
