I have recently bought a SATA 2.5 hard disk enclosure to externally connect my old Laptop SATA hard disk drive. The old hard disk drive is SATA II.
On the hard disk drive external enclosure that I have bought, there's mention of USB 3.0 and the USB cable and plug also looks like USB 3.0 type. It's a single cable with blue color inside the plug.
What I am trying to understand is would a SATA II hard disk drive, enclosed in USB 3.0 enclosure actually operate at USB 3.0 speeds?
After connecting the HDD, when I run USB Device Tree Viewer v3.2.1 it shows me H against the HDD device connected to USB 3.0 port. (Not to be confused with H: which coincides with drive letter, rather the superscript H on the left) See the screenshot. H means it's operating at USB 2 speeds.
Is there any way for me to confirm if the USB 3.0 enclosure is indeed USB 3.0 capable or it's still just USB 2.0?
I ran CrystalDiskMark on the same disk, once enclosed in USB 3.0 enclosure and another time in USB 2.0 enclosure and there's no difference in the speed whatsoever.
When I connect my USB 3.0 flash drive to the USB 3.0 port I get an S against the port in the app.
How do I confirm that the USB 3.0 hard disk drive enclosure is indeed USB 3.0 capable?
What speeds did you see? – Attie – 2018-09-05T13:17:24.507
1Update your question to include the make and model number of the enclosure. Have you tried a different USB cable, you know for a fact, is a USB 3.0 cable? How long is the USB cable you are currently using? The potential bandwisth of a USB 3.0 exceeds that have a SATA II HDD. You will never exceed USB 2.0 speeds, if the device is not recognized, as a USB 3.0 device. The device currently is being identified as a USB 2.0 device, so either the enclosure is not actually a USB 3.0 device, or something else is going on. – Ramhound – 2018-09-05T13:37:30.557
Are these enclosures self-powered (have an external AC-DC adapter), or bus-powered (get their power from host port over the USB cable)? – Ale..chenski – 2018-09-05T20:41:58.903
