Pros: Nice construction, easy to place the drives in, quiet.

Cons: Loses connection randomly and for no apparent reason especially when connected to USB 3 ports. Tried USB 2.0 and the loss of connections was far less but still would happen. Purchased a new USB 3 cable, same issue. Not 100% sure it isn't my motherboard but a USB 2 drive bay from Rosewill is attached that never lost connection ever.

Overall Review: Hoping others may chime in on their connection issues if any. Once the connection is lost a power cycle or USB plug pull and reinsert works. I am using two 3TB drives in this device and it does not feel hot.

Pros: Length, price

Cons: I bought a Vantec NextStar MX case that supports two drive up to 3TB and supports USB 2.0-3.0. It works fantastic, but the supplied cable is only 2-3 ft long. Bought this Kaybles and it seemed to work fine. However my Acronis disk images when executed at night will cause this unit to disconnect and not return unless I unplug and replug the cable. The supplied Vantec cable never has this issue.

Overall Review: Going to buy another long USB 3 cable and see what happens.

Pros: Nice features, low cost, but there are better boards in this price range with AMD-V for Virtualization (See below)

Cons: I bought this strictly for a virtual system (VMWare Server/Workstation sitting on Windows x64 or Server and Hyper V testing) Plugged in the AMD Agena 9600 and went into the BIOS. There is no BIOS options for AMD-V. I wasn't sure if this was an option but the Intel boards and CPU's do have this. Nothing in the manual or online about the option. There is no Asrock Support phone # in the manual or website. Contacted NewEgg via live support and they provided me a direct Asrock Support Phone # listed below. Asrock Tech Support # 909-590-8308 Spoke with Pablo on 6/3/09 Pablo was extremely helpful and polite. He worked with me to figure out the issue. Sure enough, there is a flaw on this mb. He even called me back twice within an hour! If you own an AM2 CPU you can enable to AMD-V virtual tech in the chip via the BIOS. However the Phenom 2 AM2+ and we assume the AM3 chips do NOT HAVE THIS OPTION even though the cpu's do feature this.

Overall Review: Pablo at Asrock confirmed this and was apologetic. He did not have an ETA on a fix or workaround and suggested returning the mb. Get another MB with the VT option as going forward Windows 7 and other OS' will be using this heavily. Don't think you are into Virtualization? You will be! Don't get stuck with an MB that doesn't support AMD-V or Intel VT! * Newegg was extremely helpful and fair. They even offered to pay for return shipping on this MB! Now that is service. I have been a long time customer and Newegg did not always do this. I am very pleased with both Newegg and Asrock over this unfortunate problem. Hope Asrock fixes the BIOS to accomodate the AM2+ and AM3 cpu's with AMD-V

Pros: Wanted this for an ESX project (Not ESXi). Read the specs on compatible Supermicro boards but found the costs too high. After some research, this mb had the same stats as the other ESX compatible mb's. Bought one, some ram, loaded ESX, used the MAtrix Raid and ESX started no probs! Both Nics worked! This is a great all in one solution for ESX! Also this MB will run XP, 2003 Server and Vista!

Cons: None, very reliable, bought 2 of them never one single problem. Most reliable MB I have ever used and I have never used Supermicro prior.

Pros: Used this unit on: Dell D630 Compaq Presario V5000 Shuttle XPC SN27p2 Two Self Built Servers using Super Micro mb Result from 7 burns: Failed on rewritable CD's - TDK and Memorex, 2x and 4x speed. Failed writing to TDK 8x DVD +R. Data was partially readable, 70% of assigned data was missing from DVD Burned Road Warrior 720p onto a disc as Data, worked! Failed 3.4 gigs of data, about 10,000 files, most corrupt. Tried again, disc unreadable. Tried burning 3 dvd of 12 gigs worth of PST files, all 3 failed with either some data present, disc destroyed. Windows XP 32 Windows XP 64 Vista x64 Windows 2003 Server This device is either utter garbage or mine was defective. Rosewill is very hit or miss. I have some of their cases and love them, but this thing blows! Not willing to try another. Will try a more reliable brand.

Cons: Read above

Overall Review: I would wait for more reviews. I could have a lemon but will not try again. Will move on to Lite On or Plextor but they are about 3X the cost!

Pros: Inexpensive, works as a true AHCI SATA connector. Works with Windows XP32/64 and Windows 2003 x32 (Not tested on x64) *The user stating that this card does not allow dynamic connection of a SATA drive is flat out WRONG. SATA drives in Windows do not use the "Safely Remove Hardware" application, that is for USB only! With this card you could also purchase something like the Vantec Kits (VANTEC MRK-200ST-BK EZ Swap 3.5) which allows you to dynamically connect or disconnect the drive from a Windows OS. If the AHCI didn't work, your system would freeze and lockup immediately. Most onboard SATA's claim AHCI but this does not necessarily mean dynamic connections. I also use the Promise Tx4 which is almost 3 times the cost, but why?

Cons: None really. It does what it says and does it well.

Overall Review: Next time you review, be sure you know what you are talking about before posting. Do some research with google, contact the maker of the product, otherwise your incorrect review will mislead people and prevent a good product from being sold to someone that could use it.
