eSATA to USB3 adapter

Postby Socaltom » Wed Jul 01, 2015 4:43 am

I'm probably the last to know, but there are adapters for hooking estata drives to USB3 ports. I picked on up on amazon.
I picked up this one for 10$
Optimal Shop USB 3.0 2.0 to eSATA External Bridge Adapter Converter 5Gbps for Latop

The good news
It works! I'm currently backing up to an eSATA drive ( ntfs) at about 16MB/s using rsync on my linux box. I tested it on my win 7 machine and got about 70MB/s ( it peaked above that).

The bad news
I have two esata docking stations. Neither will work with this, including the thermaltake unit that boots my V3 pogoplug direct from sata.

Speeds: NTFS is crap on Linux, always has been.

Functionality: this comes down to some devices not liking multiplexers, and some being more finicky about what controller spec they will work with.

Sucky.

I'm getting the same speed through the adapter to NTFS as I am going from ext4 to ext4 on the internal drives, using rsync. So no samba involvement.

Oops--- looks like I miss spelled when I mounted the drive, so the 36Mb/s was to the ext3 roots drive, not the external drive. So I corrected the speed . so its not any faster then usb2 in this configuration, I will retest once I get done shuffling some drives.

Does lsusb show the device on the running at USB3 speeds?

I've been able to get some thermaltake docking stations with two slots to work on some controllers by only using a single drive in the second slot.

Yup, that is exactly what I am talking about with multiplex behaviors
