Hi guys. I am in need of your assistance in choosing a sata to usb adapter that will support 2.5'' as well as 3.5'' under heavy usage: booting, copying huge amounts of data. I will need this to be portable, so no external power. Just USB.
I was thinking of something like this http://cdn.shopify.c...pg?v=1404114351
The problem is that, on all adapters of this type have the power usb connector using only two wires: vcc and gnd which can only take 100mA out of the maximum of 500mA on the standard USB 2.0. Any drive, when under pressure will use more than the 500mA of an USB port, which is why two of these USB ports are required.
Now, based the writings found here https://community.wd...em-healthy/7709
Each USB port is capable of delivering 500mA @ 5Volts max and each port has built in semiconductor fuse that disconnects when external device power drain exceeds rated power output. This fuse will heal itself once the offending device disconnects. This fuse inherits tolerance of 5-10% of 500mA plus or minus. That means it could be disconnecting either on 450mA or 550mA of current drain.
Most of my bought adapters perform like the above: they draw more power, fuse kicks in and the device is longer usable for several minutes.
Any of you guys have a sollution to making an internal drive portable, without any external power supply? I would prefer an external adapter as opposed to an hdd enclosure because the enclosure is hard change the drive.
