I recently needed some more space for all our various media files. With the low cost of 2TB drives today, I was able to get my Mediasonic Pro Box 4-bay and 4 2TB drives for about $400 which is a total steal.

The construction of the Mediasonic product is surprisingly nice considering the low cost. The case is very sturdy and mostly made out of metal - it feels like it could withstand some abuse without being damaged, not that I'm in to smashing hard drives around or anything. The hard drives install with just a small plastic "handle" bolted to the end of them so it's relatively simple. I did have a little trouble getting the bottom drive lined up just right with the SATA connector inside though - you do need to fiddle a bit installing the drives until you feel the connector seat itself. I wouldn't recommend this box for someone who plans on pulling the drives out and swapping them around a lot, but most folks will probably load it once and leave it sit forever so it isn't really a problem.

While I only intend to ever use this box on eSATA, I did try it out with a USB connection to my laptop as well. Performance on USB wasn't great but I didn't really have high expectations. I would say it was about typical for a USB connected disk, I don't have any hard numbers but suffice to say simple tasks like formatting took much longer than I would normally expect connected via eSATA.

Once connected with eSATA this box is screaming fast. I am using a Sans Digital eSATA card in my computer to connect the Mediasonic box - note most on-board eSATA ports don't work with port multipliers so generally you need an add-on card which is not included with the Mediasonic Pro Box. There are several available that are quite inexpensive.

HASH(0xa616ea68) out of 5 stars Good Value, No Sleep/Idle for Drives, Not for NAS Backup Feb. 20 2011
By Pablo - Published on Amazon.com
Verified Purchase
This is a fantastic value. For under $100 (as of 2/2011) you get a solidly built, compact, 4-bay SATA enclosure that supports both eSata and USB 2.0. There are a couple of downsides to the Mediasonic 3.5-Inch USB 2.0 and eSATA Pro Box 4-Bay Enclosure HF2-SU2S2 (Black):

* Although there is a sync mode that will turn the unit off or put it to sleep it only works when the device is connected to also goes to sleep or gets turned off. That's fine if you're using it with a PC but with a NAS it means that it stays on all of the time with the disks spinning. That's a waste of disk and energy if it's being used once in a while.
* There's a *really* bright blue activity light that will easily light up a room at night and is even visible from the street!
* The power connector is on the side. Makes for messy wiring and is kinda annoying.

You should also know that your host sata interface needs to support multiplexing or you'll be able to access the first drive via sata (not a problem with USB). That's just a limitation of this product and it's clear from the documentation. Just an FYI.

HASH(0xa616ed98) out of 5 stars Quality local storage. Dec 7 2010
By W. Kiley - Published on Amazon.com
Verified Purchase
Function: Given that my computer can handle port multiplying for USB and eSATA, this has met all expectations and performed excellently. The drives stay cool, I've no complaints about function.

Construction: Solid construction. The drives never jostle (and I port this thing around multiple times per week). The power input, as mentioned by others, is shaped at a right angle and I frequently see the cable bend to undue stress because of it. The lifespan of the power supply will surely be less than the device because of this and the way I use it. The only other complaint I have is the fan. On the lowest speed, mine makes an unsteady, rather loud hum. On high, it's steady and loud as expected.

Performance: Copying data from a 5400rpm 2.5" drive on my computer to 5400rpm 3.5" drive in the enclosure, I see speeds around 60-100 MB/s on eSATA and around 25-30MB/s on USB, depending on file size and whatnot. From drive to drive within the enclosure it's usually 90+ MB/s. Please note that these speeds are highly dependent upon my drives, my SATA controller, and various other external factors.

I'm glad I bought it.

HASH(0xa607a00c) out of 5 stars Amazingly small foot print! March 7 2011
By Rbhatta - Published on Amazon.com

This thing is amazingly small for an enclosure that holds 4 SATA Hard disk drives, I am truly impressed by the build quality of materials and workmanship, Installing Hard disks is easy just attach the handle with screws that they provide (Hey they even give you a screw driver!) and presto! You are ready to use your hard drives via USB or ESATA interface.

Accessing all the 4 drive bays using USB 2.0 interface is no big issues, Most of the operating systems will directly support this without any need for additional drivers. However, if you plan on using the ESATA interface you will need to plan and attach this to an ESATA port that supports Port Multiplier w/ FIS-based switching in order to access 4 HDDs simultaneously.

Some newer motherboards easily does this, Please do some research with your motherboard documentation and or update the drivers for your onboard SATA/ESATA interfaces to support this feature.

If you motherboard does not support Port Multiplier w/ FIS-based switching in order to access multiple HDDs simultaneously, You can buy a PCIe or PCIMCIA based add-on controller card that must explicitly say that it can support Port Multiplier w/ FIS-based switching in order to access the 4 HDDs simultaneously.

Amazon sells a lot of these cards for various applications (Desktop PC or Laptops)

Desktop solution : one of them is Syba SD-SA2PEX-2E PCIe 2x e-SATA Ports with SIL3132 Chipset, if you want just RAID 0 or 1 or if you want more features you need to shell out little bit more and buy other such add-on cards.

Laptop Solution: one of them is Syba SD-PCBX-ESA2 ExpressCard SIL3132 Chipset 2x e-SATA II (SATA2) Ports, 54mm, Up to 3.0Gb/s

There are many more add-on cards offered elsewhere, but do your research and make sure that ESATA interface must support Port Multiplier w/ FIS-based switching in order to access 4 HDDs simultaneously.


[+] Very Small foot print
[+] Very reasonably priced
[+] Excellent Quality and build of materials
[+] Keeps all the drives well cooled for prolonged operation
[+] Very good transfer rates even with USB 2.0 (Averaging 25 to about max 37.5 MBytes/s)


[-] Very Bright Blue LED's that flash like crazy! (Nothing a black electrical tape cannot hide)
[-] Can be very loud if the FAN is operating at high speed
[-] Power connector port is on the side which makes it impossible to keep multiple units side by side

Despite the few cons, the Pro Box 4-Bay Enclosure HF2-SU2S2 is a very good purchase!

Highly recommended! GO buy one!

HASH(0xa607a348) out of 5 stars Great storage Solution Dec 25 2010
By Christopher Aguilar - Published on Amazon.com
I have a Mac OS X 10.5.6 pro tower and I got this as a Christmas gift (you know it's love when your wife buys you storage enclosures) and I was a little skeptical about this device at first. But I plugged in the drives, hooked it to my currently installed Esata card and it worked right away. Really easy set, so far it is reliable. I do video editing so the ability to have high capacity storage on an Esata interface is critical. So far so good. Note, it does not come with a controller card!

HASH(0xa607a594) out of 5 stars Not so great Nov. 2 2011
By Farvision Networks - Published on Amazon.com

This device works - mostly. It's not appropriate for a server environment. When the server reboots, the auto-power off shuts down the entire box. This happens on a warm reboot as well as a hard reset. This is a horrible action for a sata enclosure to exhibit. Additionally, when powering up, it resets hard drives in a very scary fashion. It hard powers down and resets four or five times before the drives 'stay on'. These are brand new, known good drives. Again, the enclosure is the issue. Combined with the strange power placement, and very odd mounting system, I have to recommend against this enclosure. It may be useful as a test bench item, where you need to do raid recovery or mount multiple drives into a file-system at once for data recovery - but I've used these types of enclosures for years, and this one is not so hot. I would use Rosewill enclosures before I would rely on this one.
