Summary: It's not a true NAS, doesn't have any RAID, not fast enough to want to run as a Windows Storage Space DAS, neither USB3 or eSATA port multiplying have enough bandwidth to concurrently access all drives simultaneously, It's brilliant for what it is; a simple box to power and cool all your extra drives, *perfect* as a NAS expansion if your router supports it!
Pros: Recognized a very wide variety of HDD's and SSD's. Easy setup, nothing to configure. Actually getting the drives recognized the first time required some drive shuffling, but was a relatively painless experience. PC I plugged it into does not have a SATA controller capable of port multiplying, but no issues recognizing all bays via USB3. As it turns out, USB3 interface is faster anyway. After populating bays and using a PC to initialize and format the drives, I then pl...
Cons: While this unit is well built for what you get, and very reasonably priced compared to synology, qnap, etc - you aren't really getting alot for what you're paying. With the 4bay version of this regularly selling for under $100, there's no reason to not go that route instead unless you have to have more than 4 drives and only one port to connect them to. Neither data link to this device will allow read/writes from multiple drives concurrently; looks like they take turn...
Summary: Before placing the hard drives in this unit, format and assign drive letters for each drive. One of the drives had information on it that I did not want to loose it by formatting, so it was not formatted and worked fine in the unit. Recommend using a hard drive monitoring program to keep the drives in check like Hard Disk Sentinel.
Pros: Running Windows 7, using USB3 native from the motherboard, running 8 hard drives of different types and sizes.
Cons: Some hard drives like to "spin-down" that are in the enclosure. I have one WD "green" drive that does this. When I try to access the unit, sometimes I have to wait for the "green" drive to spin up. Only blue lights! If something "goes"...does it change to red? (Don't know!) So, always "seeing" blue lights, looks like everything is fine. Different colors would be great. Box label says that it supports Windows 8, but the enclosed "quick guide" does not say it supports W...
Summary: I'm happy to see that Mediasonic fixed the issue with the doors not closing right - the 8-day box has a nice horizontal swinging door, with a lock.
Pros: I've been using the 4-bay Mediasonic boxes without any issues for the last 2 years. Just decided to upgrade to this one, and it's great... with the USB 3.0 connection. If you're going to use this with USB, stop reading & buy it now. But for eSATA, read the "Cons".
Cons: One thing that Mediasonic is not mentioning is that this box REQUIRES AN 8-DEVICE CAPABLE CONTROLLER. In other words, cards that can only support 2 or 4 external devices will flat out NOT work. This bit of information cost me 3 days of wasted time, and 6 E-mails. If I knew about this in advance, I would have bought an 8-device PCIe card. This is the only reason I'm giving it 4 eggs instead of 5.
Summary: I needed a JBOD box for my home media server and this box is the thing!!! Easy to install, recognized all drives with data and performance is a whopping 100 to 120 mbsec transfer rate from drive to drive... You need to use it with the proper USB 3.0 card make the investment... SY-PEX20135... I did not connect it the eSata way because I am using a WHS 2011 box which has a 2TB limit and I am using 4 TB drives...
Pros: Does what it says it does Easy intallation Well built Not too noisy
Cons: *Need the right hardware to use (PCIE USB 3.0, SY-PEX20135) No indepth manual
Summary: Obviously there are things going on with USB interface cards, that are not totally standard and drives may end up not being portable from one system to another without totally reformatting and starting new. Scary, as that possibly defeats the purpose of Storage Space drives being portable across systems independent of hardware.
Pros: This is an update to my previous review: The replacement box I got works (the USB connection light is now constantly on and the box works as intended). No drop outs, cool, quiet, exactly what I wanted.
Cons: Migrating 4 harddrives from separate external USB docks into the Mediasonic box was much more difficult than I expected. All except one of the drives were not recognized at first. Through testing I realized that it was not an issue with the Mediasonic box, but was the same with any USB dock. Apparently the previously used USB docks, in combination with using Windows Server 2012 Storage Spaces, made the drives unrecognizable elsewhere. Mediasonic support was excellent ...
Summary: Their tech support is worthless. Takes them days to answer e-mails if they answer at all. There is no tech support phone number on their website. I called the sales number looking for the tech number. An informal "Hello?" on the other end. He gave me another number, which I called, and same thing. "Hello?" "Is this Mediasonic?" "Yes?" "Uhh...I have a problem with one of your enclosures." "OK...yes?" Terrible. And not fixed.
Pros: Fits 8 Bays, can run/mount them independently. Decent looking box.
Cons: Constantly have problems with drives going to sleep (not using green drives). Today, after almost exactly a year, the box stopped working and drives won't mount.
Pros: Quality build, looks nice, would be exactly what I need, if it worked. Compact. Pretty much just the drives and fans.
Cons: Does not get recognized on any of 5 PCs, Windows 8, Server 2012 Essentials, Windows 7. The USB Interface light blinks slowly, but no disks appear on any of the PCs. Tech support from Mediasonic responded via email, suggested to ensure the box was connected to a PC before powering it on. Then suggested to return. I am trying one more time.......
Pros: Easy to install the drives, just pop the plastic piece on with 2 screws and put the drive in, that's all. Fans are quiet and the build quality is great.
Cons: There are issues with this enclosure, I have a NEC Renascence USB 3.0 controller I use this with on an ACER laptop. Have been dealing with disconnect issues if I oversaturate the connection, the enclosure will drop all the drives and you have to wait for it to bring it back online. I have upgraded the firnware on the NEC USB controller and drivers, it has lessened the occurrences but I can still cause it if I try. Another thing that may annoy people are the automatic ...
Summary: Only the failure of the manufacturer to respond to my requests for warranty repair prevents me from recommending this device.
Pros: Fast enclosure when used by USB3.0 or using a separately purchased eSATA port multiplier PCI-express card (I use the Mediasonic ProBox HP1-SS3 PCI-Express 2.0 x1).
Cons: Newegg was helpful when I could not get a response from the manufacturer to repair the device under warranty when it started to shut off at random times. Fans are loud unless on low. If using eight 7200rpm drives, it is better for the drives to just put up with the noise.
Summary: Thru put from HDD to CPU is going to be determined by how fast your CPU is. However, I can transfer 50GB of data under 5min easy. So, that tells me that this machine's throughput rate is very high.
Pros: I run a digital forensics business. The locking front is nice. I process extreme amounts of data and it has to be FAST. I also need to be able to swap between servers using USB 30 and eSATA. For what I needed, (speed, security, ease of swapping HDDs) this tower gets it done. One of my better investments. :)
