BYTECC SuperSpeed USB 3.0 to eSATA 3Gbs Adapter Report

BYTECC SuperSpeed USB 3.0 to eSATA 3Gbs Adapter Review by Mr Bill "Bill" (Grand Junction, Colorado United States)

This little unit does exactly as described. Windows 7 immediately recognized it without a hitch. The device itself is quite robust in construction and can be dropped in the bottom of a bag without being too concerned that it will be broken. For my desktop I have a Vantec NexStar USB/eSATA hard drive dock which has its own power cable and brick. All the reviews I have read about portable USB3 enclosures and USB3 cables are fairly negative and complain about the heavy cables, weak connection, and need for external power and, the USB3 solutions total up to higher cost. This lets me have a full speed connection with my USB3 ported laptop for a very reasonable price.

BYTECC SuperSpeed USB 3.0 to eSATA 3Gbs Adapter Review by T. Shih (Berkeley, CA)

I'm glad to see that this kind of adapter, since I have a few eSATA devices and not all of my machines support eSATA. This adapter connects eSATA external storage devices to computers with USB connectivity, and in that sense, it enables you to:
1) Use eSATA Devices on any USB-Equipped computer (eg. use an eSATA hard drive on MACs with USB 2.0)
2) Get close to eSATA speeds when used computers equipped with USB 3.0
3) Adds an extra eSATA port in exchange for a USB port, so you can use multiple eSATA devices at the same time

I tested this adapter with my two-bay USB 2.0/eSATA RAID enclosure, running 2x Western Digital 2 TB Caviar Green Hard Disk Drives in RAID 1, and it worked very well. In USB 2.0 mode, the average transfer rate was ~30 MB/s, and using eSATA, transfers top out at ~100 MB/s. Over USB 3.0 using the BYTECC adapter, the transfers top out at ~90 MB/s. It's worth mentioning that USB 3.0 has a bit more overhead than SATA so speeds over USB 3.0 will be a little slower than native eSATA, but it's already many times faster than USB 2.0 (USB 3.0 has something called USB Attached SCSI Protocol, and this should close the gap between USB 3.0 and eSATA in terms of performance, but it's not widely supported at the moment.)

The BYTECC USB 3.0 to eSATA Adapter is a simple and straight-forward device, and it is very easy to use. No additional drivers are necessary for normal operation, and since it draws all of its power from the USB bus, no external power is required. Overall, I'm happy with it, and I've added it to my toolkit.

Notes:
1) In order to get USB 3.0 speed, you need a USB 3.0 Host
2) USB 3.0 is also referred to as SuperSpeed
3) I tested this adapter on various PC's and a friend's Macbook Pro and it works fine in USB 2.0 mode
4) According to the VID/PID, this device uses an ASMedia controller
5) UAS and LPM don't appear to be supported, but it's not really necessary for something like this.

BYTECC SuperSpeed USB 3.0 to eSATA 3Gbs Adapter Review by M. S. Ismail (Cape Town South Africa)

I bought 4 of these. I use them daily with USB 3.0 Hubs. I have not had a single disconnect as yet which is more than I can say for any enclosure based on J.Micron chip sets or even worse Asmedia based enclosures.
