Be wary using with Mac OS X

Wayne B., Newegg
23 November 2013
  • Pros: It's an inexpensive way to get lots of external storage. The case while plastic isn't too bad.
  • Cons: Is spotty working with Mac OS X.

Weak power supply

Jonathan S., Newegg
18 November 2013
  • Summary: I purchased a more powerful power brick and have no problems since. The replacement power brick is 7 amps.
  • Pros: Inexpensive unit. Works well. Shuts down drives when USB power is turned off. It's USB 3 and very quick. Seen data rates of over 40 MB/s with mechanical spinning platters.
  • Cons: The unit comes with an under powered power supply. The original power brick is 5.42 amps. While using the default power supply, I experienced the unit resetting or cutting out, like many users have complained about.

Anonymous, Newegg
7 May 2013
  • Summary: I was about to send both units I bought back until I figured this out. Using them with 8 drives to serve media to my 2012 Mac Mini media center running Plex, Sabnzbd+, Sickbeard, and Couchpotato
  • Pros: Nice little enclosure once you get it working.
  • Cons: ALL MAC USERES (and Windows 7 apparently). You NEED to upgrade the firmware for the drives to work without DISCONNECTING.

Vantec HX4

Chad D., Newegg
29 January 2013
  • Summary: **Tech support took 4 days and 2 emails to start conversing. Once they started I was able to get multiple replies from them in a single day. So not really a con. They more than made up for it.
  • Pros: USB 3.0. Cheapest 4 bay USB 3.0 I could find. Device doesn't feel cheap. Easy to use. Straight forward. Simple to setup. Good speeds to 70MB/s from what I've seen. Hotswappable*. Tech support was very responsive once they started replying.**
  • Cons: *Don't swap during read/writes while one drive is reading/writing it'll interrupt the operation but it is recoverable.

I like it

Brandon L., Newegg
23 January 2013
  • Summary: HD Tune Pro can't read SMART data from the top drive at all.
  • Pros: I got four 3TB drives (TOSHIBA PH3300U-1I72) in this thing hooked up to the stock esata port on an Asus Sabertooth P67 motherboard.
  • Cons: SMART monitoring doesn't completely work on the top drive. It works fine on the bottom three.

Best value there is

chad h., Newegg
12 November 2012
  • Summary: The fan can get loud, but the plus is it works quite well. It's adjustable to a reasonable level that still cools better than the SANS in my opinion.
  • Pros: I have this and the SANS DIGITAL TR4UTBPN. I got the SANS because of the hardware raid. However, I found the hardware raid isn't really needed, and the vantec has a sort of hardware raid already.
  • Cons: It is hot swappable, but it's kind of a pain. A tool less soloution would be great. But, I don't really use this feature.

Interesting Quad Enclosure!

Raymond V., Newegg
25 April 2012
  • Pros: This enclosure has an elaborate cooling system using plastic ductwork and a top mounted exhaust fan. The rear-loading drive mount system is interesting. The fan seems fairly quiet, although mine does not merely have an on/off switch, but rather an adjustable speed thumb-wheel. Supports eSATA (w/port multiplier) and USB 3.0. This enclosure is extremely lightweight.
  • Cons: It uses the JMicron JMS539 USB 3.0 chipset, of which I'm not a fan. Depending on the host controller used in your computer, you may or may not have trouble with the JMS539. This doesn't effect eSATA at all. I'm not sure how they can claim "Up to 5 Gbps w/USB 3.0", when the JMS539 chip bridges USB 3.0 to 3 Gbps SATA II. The eSATA chipset is JMicron JMB391, which is an ok chipset when used primarily for its port multiplier functon, as it is in this enclosure. I'm rating...
