Just a few first impressions of this enclosure which I've filled with a 4TB Toshiba N300 (7200rpm) and a 2,5" Samsung 860 EVO (using an OWC Multi-Mount).

Build quality is good, rock solid actually. The design is nice too, very Cheesegraterish. There are great little rubber feet underneath. I like that both eSATA and USB cables are included. The internal power and SATA cables are stiff though. With an HDD and an SSD there was barely enough space for them, but with two HDDs I'd imagine it could be tight.

Transfer speeds over eSATA from my cMP 3,1 via a CalDigit FASTA 6GU3 Pro are better than expected. I realise there are lightning fast drives these days but for me it's quick when a 2GB video file transfers in 13 secs.

Oddly (perhaps?) I had the same transfer speed of that 2GB file to the HDD and to the SSD. I only have Blackmagic Speed Test on my machine and it reports write 270-300 MB/s, read 470MB/s for the EVO. For the Toshiba read and write are both around 170MB/s. Sys Info reports Link Speed at 6 Gigabit for both controllers. No idea what's going on there, but still 13 secs is fine by me.

It's a rather noisy enclosure. I hadn't expected to hear the HDD so much but it's as if the drive heads are attached to my desk, ticking clearly (but only) when the drive is active. I actually don't mind that too much because I'm too much of a geek. But the fan noise is more annoying because it is a constant companion to my cMP's fans. My cMP runs cool with fans at about base rpm all the time; they almost never rev up. But the slightly higher pitch of the enclosure's whirr makes it stand out against the cMP's fans.

I have read of people switching out the fan for a Noctua model. Could anyone share if that improves the situation?

I considered other options before buying this model. The reason I bought it was to have the ability to boot off eSATA and have a bit of that Mac aesthetic (it's ok, call me vain). For someone with an older machine I'd say it's a good enclosure overall. That said, I must admit that I am in two minds about whether to keep it. There are 4-bay enclosures from Icy Box and Fantec which have eSATA and cost perhaps only 30-40% more. While they don't have the Mac Pro look alike design, they do offer more for the money. They are perhaps also quieter — does anyone know?

Cheers

I have a similar OWC dual drive unit and I found the fan noise to be too loud. I solved it by purchasing a 140mm quiet computer fan, fashioning a cardboard box around it, and placing the OWC enclosure inside with the case off and its internal fan disconnected. The 140mm fan sucks air in and air is discharged out the back of the box after it passes over the OWC drives.

I recommend a fan that connects directly to USB power. I bought this one:

Thank you for replying. That's a creative solution :) Ideally I'd like to be able to have the box out in the open so I'll look into switching the fan. But I'll also get an Icy Box (the IB-3640SU3) to compare noise levels side by side. I'll report back. One thing I like about the Icy Box is that the manual actually explicitly suggests replacing the fan (see page 17 under point 19).

So I got the Icy Box today and have tried it side-by-side with the OWC. The Icy Box is not an ugly enclosure, but design-wise it stands out more than the OWC next to a Mac Pro. Build quality is however only OK, not more. It's not at all as solid as the all aluminium OWC. Its main part – the compartment housing the disks – is made of thin metal but the rest is plastic, that is the front door and the rear fan assembly. The front door looks (and feels) flimsy. Petty details, perhaps.

Speaking of design, the Icy Box comes with both USB 3.0 and eSATA cables, and of course a power brick. But the two cables of the power brick are very short, each one just under 1m in length. For my setup this means the power brick will either hang from the desk (which puts strain on the the Icy Box's DC power jack and plug) or need to be put on the desk itself which I dislike as it's rather large (12x6,5x3,5cm). I find it odd to supply such short the power cables.

I like that it's possible to select the fan speed. At the lowest setting it is about as noisy as the OWC as a matter of decibel, but the pitch is lower, more akin to that of the Mac Pro's fans which makes it less noticeable than the OWC. The second setting on the Icy Box is considerably more audible. And the highest setting is very loud, like when a Macbook fan runs at max speed. I haven't pushed the enclosure enough to know how much load is necessary for the automatic setting to switch between the three levels, but the manual says that the cut-off temperatures between the three settings are 35C and 45C. I imagine that on a warm day ambient temps will push the internal temps above 35 and expect the fans to rev up to at least the mid setting.

Initially, I had trouble to get the Icy Box to notice that it was connected via eSATA. It took a few times of inserting the cable for the eSATA light to burn. Unfortunately the Icy Box doesn't work reliably with the Mac's sleep function, regardless of which of the Sync settings I try. When the computer wakes up there will almost always be messages of disks that were improperly removed. I have so far not had that with the OWC, which rather just integrates into macOS (and even fades the lights similar to the Mac Pro when sleeping; a nice touch).

Not being able to rely on the disks being available is a red line for me. If I can't rely on the disks being recognised when the computer wakes the enclosure doesn't meet my requirements.

I have therefore decided to return it and to keep the OWC. I'll wait and see if I'll replace the OWC's fan.

cheers
