5 out of 5 eggsUSB 3.0 to SATA III success

Pros: USB 3.0, SATA III, LED on SATA connector shows power and data, long cable, on/off cable switch, Windows 8 didn't need drivers.

I have purchased several powered SATA to USB cables and cases before which have had various issues, but this has been great by allowing direct connections to USB ports. Can get power directly from USB 3.0 port.

I have only had it about a month and have not tried it with any of my SSD drives or SED drives to know whether the electronics will interfere with SED (Self Encrypting Drive) technology which I would like to use with it.

I have tried it with a 3.5" Seagate Barracuda 4GB drive and a 2.5" Western Digital 120GB drive and both function fast and flawlessly when connected to different machines.

I have not run any speed tests but I'm going by previous experiences with reads and writes to external drives.

Cons: Haven't found any big enough to mention so far.

Other Thoughts: I would recommend this to friends.

5 out of 5 eggsVantec NexStar

Pros: Worked perfect. I use it to backup my pictures on a spare internal sata hd that was just laying around.

Cons: None so far

Other Thoughts: If you have old sata internal hd's laying around, you can now use them for back up storage for movies pic's etc.

4 out of 5 eggsworked as planed

Pros: Great Price USB 3.0 much faster that 2.0. 16 GB in less than 5 minutes

Cons: I wish the Sata connector was separate from the power connection like my older USB 2.0 adapter. This more convenient., But all I seen in USB 3.0 were like this. If separated I could leave the Hard Drive inside the machine if I wanted too, to copy.

Other Thoughts: Would buy again... If Have speed problems or conection problems make shure your USB 3.0 computer adaptors are up to date. I use Asus M5 A97 R2 and old drivers didn't recognize. Went to Asus got 3.0 patch and everything worked fine...

5 out of 5 eggsNice Product For The Money

Pros: I have purchased several powered SATA to USB 3.0 transfer cables in the past year and have not had good luck with any of them. One operated fine with a 2.5" drive, but the power supply didn't have enough "juice" to power up a 3.5" drive.

This Vantec NexStar appears to be an exception. I have had it about a month now and have used it a number of times with both 2.5" and 3.5" drives and SSDs and have experienced no issues whatsoever.

I first used it to create a system image (74.4GB) of a Samsung Pro 256GB SSD on a 1TB Seagate Barracuda 7200 RPM SATA 6GB drive, and it made the image in 7 minutes and 31 seconds. As a test, I connected the same Seagate drive directly to a SATA 6GB connector on my computer and it made the same system image in 7 minutes an 2 seconds.

Cons: Fairly minor.

The power switch is located almost directly in the center of the power cable which I find a bit odd (why not locate it closer to the SATA connector?) but it's not enough of an issue to dock it an egg (if you need the power switch closer to you, simply plug the wall wart into an extension cord).

Other Thoughts: The (wall wart) power supply cable is 62" long and the USB cable (attached to the SATA adapter) is 48" long. It's a heavy duty cable, but it is long enough so as not to be inflexible (it's 0.19" -- or 4.5mm thick -- or about 2/3 the thickness of most modern SSDs).

There is a red LED that lights up when you turn power on. The SATA connector "case" is about 2/3 the size of a deck of cards and about 80 percent as thick.

It's a fairly simply unit but the construction appears to be sturdy and it has worked fine so far. If you are looking for a powered SATA to USB 3.0 transfer cable, this one is decent for the money.

I would recommend it to friends.

5 out of 5 eggsJust works as a tool should

Pros: I ordered this in preparation of moving to a SSD on a laptop. Two days after I got it, a hard drive on a different machine had problems and this tool worked perfect. I was able to power on the 3.5 1.0 TB WD drive and copy all the data files. Computer did not have USB 3 so it took longer than it could have; but the Vantec adaptor worked great the whole time!

Cons: I have not had any yet.

5 out of 5 eggsGreat

Pros: This is a super little adapter and works incredibly fast. Mechanical drives still register over 110 MB/s through this and It's great to be able to make improvised external HDs or add extra capacity.

Cons: Only problem is the power switch literally seems to do nothing as the USB powers it just fine and when plugged in to USB, the power switch won't interrupt and turn it off.

Other Thoughts: I have an older model of this as well and they are both pretty solid, fast, and great to add extra HD capacity (I have over 8 HDs).

5 out of 5 eggsWorks Well! Fast!

Pros: Works great and is fast!
USB 3.0
Powered - 3.5" drive support
On/off switch on power cord

Cons: None yet

Other Thoughts: If you don't plug the power in and you plug in a 3.5" drive, nothing bad happens, it doesn't try to spin it up or anything, it just acts like it doesn't recognize it. And you don't need the power supply to use it with 2.5" drives!

Also when you safely disconnect, the drive will stop spinning, and then you can remove it without unplugging the USB cord, and then you can plug in another drive without un-plugging and plugging in the USB cord.

5 out of 5 eggsIt's Good

Pros: This adapter makes it so much faster to transfer data and make image backups (using Macrium Reflect).

I've been using Crystal Disk Mark to test speeds on this adapter, hooked up to a SanDisk Extreme 120GB SSD. Reads and writes with this adapter, using USB 2.0 are usually around 30 MB/s, up to 40 MB/s (depending on the computer you are using).

Using USB 3.0 ports:

Dell PowerEdge T110 II Server:
Seq. Read: 253 MB/s
Seq. Write: 159 MB/s
4K Read: 16.52 MB/s
4K Write: 25.91 MB/s

Dell Latitude E6430 Laptop:
Seq. Read: 179 MB/s
Seq. Write: 154 MB/s
4K Read: 18.17 MB/s
4K Write: 41.63 MB/s

Using USB 2.0 ports:

Dell PowerEdge T110 II Server:
Seq. Read: 33.54 MB/s
Seq. Write: 29.95 MB/s
4K Read: 7.1 MB/s
4K Write: 8.0 MB/s

Dell Latitude E6430 Laptop:
Seq. Read: 41.10 MB/s
Seq. Write: 39.37 MB/s
4K Read: 9.9 MB/s
4K Write: 13.6 MB/s

The greatest difference was realized on the PowerEdge server which has a cheap IOCrest / Etron 188 USB 3.0 card in it.

I'm not seeing improvements quite as dramatic from within Macrium Reflect. In that software my backups are taking about half as long, sometimes better and sometimes worse.

Cons: Some of the other complaints are indeed valid. And yet I'm willing to overlook most of them because they are so minor.

One of my complaints is that I have to remove brackets and holders from hard drives in order to hook this thing up. Minor complaint, I know.

One other point. I always power up the drive before you plug in the USB cable. I never have trouble this way with the adapter not being detected.

5 out of 5 eggsWorks at USB 3.0 speeds!

Pros: Fast, very fast

Cons: None

Other Thoughts: I was skeptical but this thing works. I mount my 2TB drives to my new Ultrabook through the USB 3.0 ports and the speeds are crazy fast. Forget eSATA or FireWire - this is the new standard and no need for high-end equipment - if you want to mount a SATA (6GB/s) to your PC then just buy this.
