Disappointed with Samsung 850 EVO write speeds using Inateck USB 3 Enclosure

[bootz]

Using Blackmagic, the write speed to my Samsung 850 EVO is topping out at 150 MB/s. The read speed is great, hitting 500 MB/s at times. I'm using the Inateck FE2007 (USB 3 with 3-port hub). My hardware is a rMBP mid-2012 running OS X El Capitan.

Thanks

What is the speed when connected directly without a hub?

The Inateck FE2007 has a 3 port USB hub built-in to the enclosure - all one piece.
The site says that it supports UASP, and should give you good speed with an SATA drive.

That being said, you may want to try a different USB cable, or a different enclosure (might be the SSD itself, and you should check for firmware updates?)

No problems using an FEU3NS-1E with a Samsung 840 1TB. That enclosure definitely does UASP and lets you have read and write speeds in the 400+ range.

With an SSD you don't have a motor and exposed electronics to protect. You can use a simple cable that is USB 3 on one end and a SATA III controller on the other end that does UASP. That combo can save a little space in a briefcase or camera bag.

Thanks for the replies. This SSD was used in a Windows PC in the past and I did use the Magician software to enable Over Provisioning and RAPID Mode. I guess I should try and connect it to a Windows machine and revert back to the Magician default settings (no Over Provisioning and No RAPID mode).
