Question: Can i use this for USB 2.0?
Document: I have a bunch of eSATA external drives because I was too impatient for firewire and usb when they were the normal means for data transfer. Now that I have a macbook air that doesn't have a PCI card slot this allowed me to still make use of my giant externals to hook up to my mac. The speeds are what I expect from USB 3.0. Solid product.
This little baby should be included when you buy A NexStar 3000 External Hard Drive. I was using USB 2.0 to transfer data, but I would lose information often.
We have an external drive array with Firewire, USB2, and eSATA connections. We bought a new laptop USB 3.0 connections only. This adapter worked first time, no issue, and is substantially faster than USB 2.0.
Previously, I had used a Windows-based system with an eSATA port with good success. I have a 2TB drive in a Blue Vantec NexStar 3 eSATA Hard Drive Enclosure NST-360SU-BL that worked well connected via eSATA on that system.But when I switched to a Mac, I had to buy an adapter because the Mac has no eSATA ports and USB 2.0 is really slow by comparison.
This product works very well and does what its supposed to do, i use this to connect a 2TB G-Drive (with esata) to my new macbook pro (that has usb3.0) and this was exactly what i was looking for. If you have an esata drive and usb 3 on your computer you cant go wrong with this product (just keep in mind that you need to already have an esata cable)
Works well with fast speeds. This has allowed me to use an older HDD enclosure with my new USB 3 laptop. Thanks for a quality product.
Clever gadget. Gave new life to my LaCie Neil Poulton black esata drive when I got a laptop that only had USB 3 connection. Easy to use and no setup.

Bought this to take advantage of a NAS device with eSATA and Mac Mini's USB 3.0. Worked perfectly. I now get amazing transfer rates copying between the two. Didn't seem cheaply made as other reviewer suggest. Would recommend to anyone needing such a solution.
The label &#34;eSATA to USB 3.0 Adapter&#34; implies that an eSATA input gets converted into an USB 3.0 output. That's what I needed. But this product is mislabelled and does the reverse! So do all the other such adapters I've located, whether mislabelled or not. I.e. it produces an eSATA output from a USB 3.0 input.
Answer: Yes you can, but the speed is reduced to usb2.0
