Mediasonic Probox 8-bay 3.5" USB 3.0 / eSATA DAS Review
by Ganesh T S on August 4, 2012 7:55 AM ESTFinal Words:
As we come to the business end of the review, we will summarize the pros and cons of the Mediasonic Probox 8-bay JBOD unit first.
Pros:
- Provides quick access to upto eight 3.5" SATA HDDs
- Fulfills basic functionality without flaws and has decent performance
- Dual interface (eSATA and USB 3.0) support
- Automatic fan control and ability to turn on and off along with the PC
Cons:
- eSATA is unusable for configurations with more than one drive unless SATA controllers with port multiplier support are used. Even in that case, only add-on cards using the Silicon Image 3132 / 3124 controller can access all the eight drives using the port multiplier feature (standard specifications seem to call for support of upto 5 SATA devices only through a port multiplied link)
- For the pricing of the device (more than $250), an add-on card with the appropriate Silicon Image controller must be bundled
- The unit forsakes support for 2.5" HDDs / SSDs, and the latter don't work even with 3.5" adapters. The only way to solve this issue would be for Mediasonic to bundle a tray capable ot supporting both 2.5" and 3.5" HDDs and slotting in perfectly with the fixed SATA connectors inside the unit.
- The bridge chips conform to the SATA 3 Gbps specification only, and USB 3.0 port is unable to deliver full performance. With eight drives being accessed simultaneously, it is quite easy to saturate a 3 Gbps link. Bridge chips capable of 6 Gbps support would definitely become necessary when DAS units with SSD support come to the market.
Motherboard vendors should also make sure that their eSATA ports conform to the port multiplier specifications. However, the rise in popularity of USB 3.0 probably means that vendors don't want to spend too much effort on this. Thanks to its dual interface, the Mediasonic Probox enclosure is compliant with a wide range of systems. It should be able to satisfy the needs of most consumers looking for a 8-bay JBOD enclosure.

Er, heh sorry TuxRoller. I mistook you for another person. My mistake.tuxRoller - Sunday, August 5, 2012 - link
Heh, no problem:)heron_kusanagi - Saturday, August 4, 2012 - link
And using a eSATA PCI-e card that supports port multiplier. I say that this HDD enclosure will really do well with a bundled eSATA PCI-e card. At least saves some hassle from the consumer side. Although USB 3.0 will solve that issue somewhat, I suppose. Still, this is a nice way to expand the HDD storage of local systems.sheh - Saturday, August 4, 2012 - link
What do people do with these things, I wonder. If it had a network interface in addition, then alright. But even then, for the price these things sell, you might just as well get a PC. More flexible, too.ganeshts - Saturday, August 4, 2012 - link
Try getting a 8-bay NAS for around $300 :) And try assembling a PC with this low power footprint when 8 drives are added. In addition, it is not straightforward to have the drives attached to a PC be visible as a set of drives for another PC (which is the point of this gadget - a direct attached storage unit)bigboxes - Saturday, August 4, 2012 - link
Straightforward for who? AnandTech readers? I have a 9 drive file server (one for the os and 8 for the files to be shared). It's hooked up to the a gigabit switch and then shared with all my home's PCs. I map all of the drives I wish to share on a particular pc. Not too complicated. It's my old A64 box. It's got 2gb of ram and more than enough horsepower to serve up files. I use a Seasonic psu that is not stressed in the least. Quiet and quite flexible. I use a couple of SATA2 pci cards to hook up all the drives. When I have trouble it's easy to troubleshoot the issue.Lonyo - Saturday, August 4, 2012 - link
I'll get back to you hopefully next week when my Celeron G530 (to be underclocked) on an mATX mobo with 8 SATA ports is ready and set up.Rather than challenging the readers to do this, shouldn't you as the reviewer be considering it, and actually exploring the possibilities?

Oh, and total cost for an 8 bay mATX case ($25), G530 ($50), motherboard ($80), RAM ($20), and then $50 for a low wattage 80+ PSU gives you a total of around $225 for an 8-bay box that can also have even more storage added through PCI/PCIe controller cards, as well as USB drives being connected to it.ganeshts - Saturday, August 4, 2012 - link
Guys,Everyone is talking about a NAS here, while I was talking about a DAS. Do you have a 8-bay PC which can be connected to another PC and have all the 8 bays visible over a eSATA or USB port?
The whole intent is to have storage which can be taken from PC to PC without disassembling, and operating at the max. bandwidth provided by USB 3 or eSATA. With all your solutions, you can either access the drives at full bandwidth only on that host PC or on another PC through a GbE link limited by many other factors.

People use these things to have potentially flexible, fast and economical storage.Sure it can be more complex to setup. But power consumption wise. It will almost certainly win over a NAS. Which in turn relates to the never ending cost of the device running over time. It will almost always be faster, and can be just as bit as flexible as a NAS. Although, a network not withstanding. Can only connect to one system at a time.
It all really boils down to taste, and thought process put into your final objective.
