Sandisk Extreme USB 3.0 Extremely Slow.!

Hi

 

I just purchased Sandisk Extreme USB 3.0 pendrive and i get read speed of just 39 mbps.

 

I tried formatting in various filesystem like NTFS, FAT32, exFAT etc, but same 39 mbps.

 

My configuration

 

core i7 ( 3rd generation ) , 8GB RAM, 5400 RPM hDD.

 

Even write speeds are around 40 mbps.

Are your USB ports 3.0? If you plug a 3.0 flash drive into a 2.0 port, you won't see any speed advantage.

Definetely, that's the issue. But knowing that it's i7, it should be a USB 3.0 already. Can you verify this? Also, try this on another computer just to isolate the issue. <img src="https://imagicon.info/cat/5-43/16x16_smiley-happy.gif"/>

Read Speed : 30 mb/s and write speed : 28 mb/s

 

I certainly do not expect such slow speeds because even my USB 2.0 pendrive performs faster than that .! Smiley Sad

it is transcend.

 

However it is just because my USB 3.0 Sandisk pendrive is slow, nothing else.
