StarTech.com 3 ft USB 3.0 to eSATA Adapter - 6 Gbps USB to HDD/SSD/ODD Converter - Hard Drive to USB Cable (USB3S2ESATA3)

Works better than expected. I purchased this to use an old 2TB external drive. It has a USB2 port and an esata port. This cable adapter plugged into a USB3 computer port was 3.5 times faster read and write speeds compared to using the USB2 port. Well worth the money.

The StarTech adapter works (seemingly flawlessly) between my MacBook Air 2015 and an external RAID drive. In fact, it even works with up to two USB3.0 hubs in between (not sure that is recommended, but it does work), despite my concern that the total length of the cable is about 3 ft, which may be close to the max an eSATA cable can be (not sure about this). I did some performance measurements, and the throughput was the same regardless of whether I used one or two USB hubs, about 70 MBps, or 550Mbps, well below the theoretical 5Gbps for eSATA, so the throughput is limited by the drive/file system rather than the eSATA or USB3. Despite this, it is interesting to know that the USB3 hubs, one or two (I didn't try more than that), have no negative effect.I did try the eSATA-to-USB3 adapter by another brand (Vantec), and that caused my MacBook Air to not even boot up. This tells me that the StarTech product is of higher quality (and thus worth the higher cost).

Works as it is supposed to. Saved me when my remote hard drive was knocked over and I needed to use this connection.

Works perfectly to adapt old LaCie 2TB external quadra drive to 2017 iMac for speedier data connection.The USB on the Lacie wasn't connecting reliably, but eSATA works great & much faster data read/write.Works fine with Time Machine on the iMac running Monterey.

Better than USB 2. Which was my only alternative. This was a decent save for a NAS backup hub where the eSata speed is not even noticed

Claro, aquí tienes una reseña personal y positiva del adaptador StarTech.com USB 3.0 a eSATA.Mi opinión sobre el adaptador StarTech.com USB 3.0 a eSATAComo fotógrafo y editor de video, a menudo tengo que trabajar con una gran variedad de equipos de almacenamiento. Mi disco duro externo principal utiliza una conexión eSATA, que ofrece velocidades increíbles, pero no siempre es compatible con todos mis ordenadores, especialmente con los más nuevos que no tienen este puerto. El adaptador de StarTech.com ha sido la solución perfecta a este problema.Lo que más valoro de este adaptador es su sencillez y su eficacia. No hay necesidad de instalar controladores ni software. Simplemente lo conecté al puerto USB 3.0 de mi portátil y, al otro lado, a mi disco duro eSATA. El ordenador reconoció el disco al instante y pude empezar a transferir archivos de gran tamaño sin ningún tipo de problema.La velocidad de transferencia es otro punto a destacar. He usado otros adaptadores en el pasado, pero este me ha sorprendido por lo bien que aprovecha la velocidad del USB 3.0 para replicar una conexión eSATA de 6 Gbps. Esto se traduce en menos tiempo esperando a que los archivos se copien y más tiempo editando o trabajando.El diseño es compacto y robusto, con un cable de tres pies que me da la flexibilidad necesaria para colocar el disco duro donde me sea más cómodo. La calidad de construcción es excelente y se siente como un producto duradero, lo cual es muy importante para mí, ya que lo uso a diario.En resumen, si tienes un disco duro eSATA y necesitas una forma fiable y rápida de conectarlo a un ordenador con puerto USB 3.0, este adaptador de StarTech.com es una inversión que vale la pena. Me ha ahorrado mucho tiempo y me ha permitido seguir utilizando mi equipo de almacenamiento de alta velocidad, haciéndolo compatible con cualquier ordenador moderno. Es una compra que recomiendo sin dudar.

Update as of 3/6/17...Of course, I missed my chance to return the product. I have been busy.I just finished chatting with Startech.com. My enclosure is a different brand, but the concept is still true.Turns out... The age of my 4 bay enclosure has nothing to do with it. This cable is designed to work with only single enclosures. You would need a port multiplier if you have multiple hard drives that you are trying to connect.For now, being able to access a single drive at a time is okay, but at some point, I am going to buy a new enclosure and I am going with USB and one that is less noisy.Sooooo... I read alot of reviews and I am pissed at me and everyone as that little important detail would have been nice to mention. lol... Meaning that the cable does not work with 4 bay enclosures.Anywayz....The below, you can read at your leisure.I updated the stars from 1 to 3.Pros:1. Works great for single enclosure. (Note: Make sure that you are connected to a 3.0 port.) I can access one drive of my 4 bay enclosure with no problems.Cons:1. It works with only 1 drive and no one mentions that. Clearly, I do not know alot about technology as I guess everyone took that for granted._______________________I might update this star later, but for now I am outright disappointed. I think it is my fault so you may still buy this item and it may work for you.The reason it might be my fault. I own an older and likely one of the first Startech 4 bay enclosures. I love this thing! It has saved my hide more times than I can count.Well... I initially I was having problems with my eSata cable so I bought a new eSata cable and it worked for awhile, but it never fails that at some point I have to wiggle the cable to get the computer and the enclosure to work.Sooooo I bought this cable thinking it would fix my problem. It only kinda recognizes intermittently one drive. I have tried swapping the drives. Replugging everything. Verifying that I have the latest drivers as well as verifying that I plugged into a 3.0 usb port and so far.... No luck...I was soooo excited about this product thinking that I would be able to connect my enclosure and I would have access like before on the eSata cables and so far no dice....Oh... so what does the above have to do with you? lol...Be sure to check your enclosure, the age of the enclosure, the drivers, and all cables before buying this cable as it may or may not fix your problem.For me, it was worth the risk as my current eSatas were failing anyway.When I have more time to work on this item, maybe I will be able to fix the problem and can update this review.
