1 out of 5 eggsWorked once in the dock, now computer won't recognize it

Pros: It is a good looking dock and enclosure. Works great as an external usb 3.0 drive enclosure and that is about it

Cons: I bought this to have a easily removable backup from my desktop PC. I installed it and did the first copy with no problems(using a 500gb hard drive, not SSD). After two days, it is not recognized by the computer even though I left it in the dock. I can take it out of the dock and use the supplied usb cable and it comes up. Put it back in the dock and it won't come up. I even tried different sata cables as well. Not to sure why it worked once and not again.

Other Thoughts: If you want a clean and fast usb 3.0 hard drive enclosure, go for it. As far as using it as a dock, I haven't had good luck like the others before me.

5 out of 5 eggsgreat enclosure hope they get more

Pros: It works great so that is what counts. Nice build quality at a low price and it looks good. It is great to have both the sata and usb3 options I use this drive with esata on my laptop and it works great. Get a few of these and some mini hard drives and it makes a great hot swap backup drive setup.

Cons: no cons except that I want to buy more and they are out of stock now

Other Thoughts: My floppy drive bay used to hold 1.44mb of data now it holds 1TB at sata 6G speeds. Future shock

5 out of 5 eggsDoes what it designed to do...

Pros: Clean looking no frills enclosure. I bought this to be able to swap OS loads without a dual boot configuration. Let's face it, multiple operating system boot configurations while convenient are inherently insecure. The ability to swap between OS installations completely and cleanly while slightly more inconvenient provides a better piece of mind, IMHO. I am running Windows and Linux loads with separate sleeves (you can purchase a sleeve separately) and it is worked as advertised.

Good budget price point

Internal enclosure with removable drive sleeves

Cons: If you are looking for bleeding edge speed, a hard core gamer(although I do game), or want an external enclosure this might not be for you; and you are probably not looking at this anyway.

I have not had any performance issues that I would deduct an egg for as I am not trying to bleed it dry for speed. Both my recently purchased laptop drive and SSD work just fine.

Other Thoughts: This is designed for end user who would like to have the convenience of swapping drives without cracking the case or have to play with eSATA. If you are looking for solid construction and good performance this will provide a good starting point for a reasonable price.

If you want to use the sleeve externally, be my guest, but remember, for the price there are other external enclosures on the market that are designed specifically for that purpose. This will do it in pinch, but why monkey with it if you have alternatives.

3 out of 5 eggsStill has same old eSATA/SATA issues

Pros: -Good build quality, nice finish on enclosure.

-All necessary cables included.

-USB 3.0 (external) + SATA (docking).

-If you have the right cables you can still use it as an external SATA device if you know what you're doing.

-Overall, in *most* circumstances this is a great device, worthy of 5 Eggs.

Cons: -No case/pouch/sleeve included for external enclosure (personally I could have gone without the internal SATA cable and would rather there have been a case/sleeve included--I have lots of SATA cables). Minus one egg.

-Enclosure seems to "catch" at one point in the dock causing it to be a little tough to remove. This also digs at the serial sticker on the enclosure each time you remove it so I'm sure over time it will just destroy that sticker, hopefully warranty issues (if any/ever) Vantec will recognise that and not hold it against you.

-Power/access lights seem to just go on solid when docked (i.e. access light doesn't actually work in docked mode, only when connected via USB). Not a big deal IMO but thought I would mention it.

-Manual fairly lacking; would have been nice if drive PCB/tray was tool-less for the drive at least (i.e. no screws required to hold it in there). Again though these are not big deals.

-Still has eSATA/SATA issues despite not actually being an eSATA device at all. Minus another egg.

Other Thoughts: This is a great little device TBH. However I bought it thinking of what an ingenious idea it was to just use a standard SATA connection at back as this, in theory, should avoid all the mess that occurs when trying to use eSATA. If you don't know what I'm referring to, I'll give a short summary of the issues you might encounter with eSATA connections. I've been using eSATA and external SATA device connections since before AHCI was even popularised on southbridges so I've encountered a lot of different issues over time, that still cause problems to day.

For example:
-Some drives don't work in some (typically older) eSATA enclosures properly. Some combinations require using a "FORCE 150" jumpering (older drives) or changing in firmware (more recent drives) to remain in SATA 1.5Gbps mode. Most modern drives you can't set this at all meaning some won't work in older enclosures/docks. Also from a speed standpoint, modern HDDs and all SSDs will suffer over a slower connection even if you can get them working this way.

-Drives/encolsures often work better/worse over eSATA depending on cable length and quality, and with different PCs/ports. It's not really too consistent.

-Sometimes drives work fine in the enclosure and have great sequential speeds, but 4K/QD transfer speeds are mysteriously incredibly slow. This is really of no consequence to HDDs but is serious problem for SSDs.

There's a bunch more things that can happen but to say the least, there's LOTS of quirks with eSATA. This is likely the reason most people use USB (2/3) for external drives more than anything--simplicity and consistency. Though speed suffers, getting eSATA to work is sometimes a headache.

The whole problem is generally the bridge chips. eSATA isn't a totally native connection as one would think. There is always a bridge chip from the drive to the external port and incompatibilities with the bridge, drives, and ports, are where the issues come from.

All that said when I bought this product I thought those worries would be over. However that wasn't quite the case. I still have one SSD which won't work with the enclosure when it is docked. It detects but not properly and then you cannot access anything on the drive. The funny part is if I connect the actual drive connectors on the enclosure it works fine with SATA/eSATA connection! Therefore there has got to be a bridge chip/electronics in the dock portion which causes the compatibility issues. A bit of a shame but it's the way it is because the one drive I really intended to use with it is the one that won't work in the dock.

FWIW it does work excellently with drives that do work in it. Realistically it gets 3.5 Eggs from me, but you can only give full-egg ratings so 3 Eggs it was. I do really like the device, don't get me wrong, but it does still have that SATA bridge compatibility caveat.

5 out of 5 eggsVantec EZ Swap Great for Travel

Pros: This package will allow you to install a removable hard drive pack that is both SATA III and USB 3.0 compliant. You can have these drive packs installed all the time in your desktop and remove with a push of button and throw them in your bag for travel, using the USB 3.0 connection with your laptop. They are hot-sway compliant and rugged cases. I use them in all the desktops and even the server with WD Red drives there.

Cons: None

Other Thoughts: I have used all versions of these drives for over five years now and just recently upgraded them all to the SATA III and USB 3.0 version.

5 out of 5 eggsGreat peice of hardware

Pros: 1- All metal enclosure, with a very fine and almost imperceptible grainy texture, allowing for a firm grip : it doesn't feel like cheap metal at all even though it could be.
2- USB 3.0 works as expected.
3- It uses a USB 3.0 A Male to Micro-B Male Cable, which is standard and available at Newegg in case you loose it, for about 4.00$ (e.g. Item N82E16812422983)
4- I just love the docking option in a 5.25 inch drive bay with full SATA III connectivity (no need for drivers of course, as it doesn't provide its own controller but instead acts as just another SATA III drive in the PC : you must have an available SATA III port on the motherboard).

Cons: 1- No eSATA III capabilities, but considering that an SSD don't go beyond around 550MB/s, and that USB 3.0 provides up to 625 MB/s, there's no real need for an eSATA III port. No con here.
2- The SSD/2.5 HDD enclosure doesn't slide as smoothly as would be expected in the 5.25 drive bay, but it's not a big problem, just don't be too "brutal" with the guyzmo. No con.

Other Thoughts: I was looking for a convenient way to transport data without requiring some networking means, and in the most compact, efficient but still affordable medium which is an SSD. This product answers exactly to my need. A great product which I recommend, you won't be disappointed.
