4 out of 5 eggsworks well

Pros: worked right out of the box took all my drives 2 1.5tb 2 2tb
the esata worked like a boss never had it work in the past

Cons: the front cover killed air flow and made the drives get hot.

Other Thoughts: a full mesh front cover is needed for better drive cooling

4 out of 5 eggsWorks well so far.

Pros: Works exactly as expected. Highly recommended if you intend to back up your files to disconnected hard drive storage. I use it for writing backups to hard drives which I then remove to prevent virus contamination. It's also probably good as just a storage expansion, especially if you have a laptop and want more storage to use when you are home at your desk.

Cons: The front opening door does not seem too sturdy, but that's not a huge deal unless you are moving it.

Other Thoughts: I wish they included more then 4 harddrive brackets. They are not needed if you are inserting a harddrive but harddrives are hard to remove without them.

1 out of 5 eggsMoronic design, non-functional eSATA

Pros: Design for physical installation of disks is actually pretty nice, easily attached the handles, slid 4 drives into the bays, closed the case and connected it to my eSATA port. Power uses simple 3-prong plug instead of wall wart.

Cons: Well, everything else. I connected power and eSATA, turned it on, lights come on, I hear some drives spinning up, then it just shuts off.

I repeated this a few times, thought I might have a drive that is loosely connected, but reseating each did nothing, nor did removing a couple until there were just 2 drives.
All 4 drives are known good, were working in other external enclosures this morning. Also eSATA port supports Port Multiplier, was using it with Thermaltake BlacX 2-drive enclosure this morning (and switched back to it during troubleshooting).

Switched to USB cable and it worked immediately, but when only eSATA is connected the device powers up and then shuts down after a few seconds.

This is the moronic part - there is a button to switch interface from USB to eSATA, but from the indicator lights it defaults to USB and powers itself off before you have a chance to switch it to eSATA. Possibly it's not detecting the eSATA cable,
but I've tried 2 cables, and reconnected the BlacX, so I know both cables are good, the eSATA port is good and supports Port Multiplier, and the only problem is this enclosure.

Other Thoughts: I hate devices (or software) that fail silently with no indication of the problem and no way to troubleshoot. I'm guessing that it's not detecting the eSATA port - maybe it's eSATA interface is bad? - but I can't troubleshoot it at all to confirm.
So about an hour of my time wasted, I'll be requesting a return.

1 out of 5 eggsNot too happy

Pros: Compact...has fan with variable speeds...room for four drives...USB3. I love the concept.

Cons: Doesn't work properly under load...as soon as your want to move files the USB drops out and all drives disappear from explorer. Doesn't need any more cons after that. Early retirement unless I can find a solution.

5 out of 5 eggspretty decent

Pros: Works very well and allows me to use 4 drives at once. Decent build quality. Liked it so much I bought 2 of them.

Very straightforward assembly instructions and came with a screwdriver in the box.

Cons: The auto fan control doesn't seem to work. The fan always stays at setting 3 (slowest). (@ambient 30C) I had some drives reporting SMART temperatures as high as 50C and the fan never ramps up to 2 or 1. Found that if you remove the front cover the drives drop 5C within 15 minutes in auto mode (at the cost of a small noise increase). Both my probox's have identical behavior.

4 out of 5 eggsA poor mans RAID5 solution.

Pros: Sturdy case with seemingly good electronics.
If you just want to combine several old drives into one USB-eSata connection good.
I put 3 disks – each size 3TB and used the new Windows 8.1 “Storage-Space” option to stripe the data (with parity) for a RAID5 type of resilience (fault-tolerance).

Usable resilient storage (due to the saving of parity)… 7TB.

VERY cheap compared to other RAID5 solutions.

Cons: My computer had some trouble recognizing the new disks. (But finally did.)

Very..... VERY little documentation

Although docs say use unformatted disks to initialize as storage-space, format them or you get an error.

The "Storage-Space" option is ONLY available with Windows +8.0 . Otherwise the disks just appear as individual USB connected disks.

Using the Windows 8.1 Storage Space option "Striped with Parity" (was known as RAID5) the usual poor disk write performance was noticed. (From the normal +100MB/second to around 30MB/s.) This is not the enclosure fault, but the additional activity of data striping and parity creation.

The "auto" fan setting allowed my disks to overheat and slow with constant full-time loading. Set to manual medium-high setting (a bit noisy) and the disks went at full speed. Expect the "auto fan" setting to work just fine when not running at full speed (loading data).

Other Thoughts: Considering replacing the rather noisy sleeve-bearing fan with a top-quality (quieter & more efficient) ball-bearing fan.

But considering just $100 for a RAID5-like solution... (Others run +$500 for just the enclosure) quite a good buy.

And, considering you know a bit about computers (due to the very little documentation), I can recommend this enclosure.

5 out of 5 eggsNice 4 Drive Box

Pros: Works well, 105 Mb/s write speeds with USB 3

Cons: Fan can be noisy, tools needed to change drives.

Other Thoughts: Fan has been noisy for few months, contacted Mediasonic today with complaint. They mailed me new fan out the same day. Better than expected response from manufacturer.

2 out of 5 eggsSpotty Performance

Pros: 4 Drive bays with small footprint.

Cons: Intermittent, frequent dismounts/remounts of HDDs (all drives simultaneously). Less commonly, the unit powers off completely.

Other Thoughts: Windows 7 x64P This unit houses four 3TB drives and is used for multiple daily backups of Premiere Pro scratch drives. It was purchased in 10/2014 and its behavior has been consistent from day 1. . It is connected to computer via USB 3.0. e-SATA has not been used. Connection is made to rear, on-board USB 3.0 port. Front USB 3.0 ports have also been used, but no change in behavior. Cables have also been swapped--again, no change in behavior.

Event viewer will sometimes report disconnects as "Controller Error". No errors are shown when the unit powers down.

I would not recommend this unit for anything other than temporary, trivial, backup.
