For some odd reason. Both of my brand new external drives would become stall at around %98 of transfer speed for about 6 sec. One of them is WD 1TB Elements SE Portable http://www.newegg.com/Product/Produ...cm_re=WD_Elements_1_TB-_-22-136-996-_-Product . And the other is Kingston’s SSDNow. UV400 120GB. https://www.kingston.com/us/ssd/consumer/suv400s3 Is it normal for external storage to buffer?.
My guess... your Windows external device buffering is hiccuping for some reason. When your devices are plugged in, you can go to your DEVICE MANAGER and open up your DISK DRIVEs section. <right-click> your device in question and select "Properties." In the "Properties" window, select the POLICIES TAB and ensure that WRITE CACHING is set to ON for the device(s) in question. To be safe with WRITE CACHING, you should always use the Safely Remove option from your SystemTray when extracting those devices. This ensures that any DATA currently cached for this device will get written before Windows will allow removal of the device.
Thanks @TheRollbackFrog That solved my "problem" on Windows 7 when copying files to external disk. I didn't have it on Windows 8.1 - maybe it configures drives differently?
Another thing is. I have powered USB 3.0 hub, plugged into none powered enclosure. I am getting 500-300 MB/s speed out of them. Is it normal for USB 3.0 to have that kind of transfer speed?.
I don't know what's in that enclosure but if it's HDDs... can't happen. I don't even think an SSD can xfr that fast as a USB-based device. Possibly your number is 500-300 mb/s (megabits per second rather than megabytes per second)... and I don't know why your speed range is backwards (should be slowest to fastest). If 300-500 megabits/sec, 40-60mB/s is reasonable if not a bit slow for HDDs & USB3.
LOL. You are right. I have just made a typo.. I am getting 500-300 mb/s. I will post more detailed info later on.
