1 out of 5 eggsNow it has become not dependable

Pros: Cheap price, easy setup, was dependable for the first month.

Cons: Just over one month not dependable

Other Thoughts: This worked very well for the first month. I had no problems at all. I have it setup as a JBOD with 4 drives. I keep it unplugged and powered off and only use it weekly for doing my system and media backups so I have only had it on several times. I have had this just over a month and now when I turned it on it is now telling me I have to format the drive. I have tried power cycling several times with the same result. This went from a very reliable device to one that is completely undependable and worthless. A backup device has to be reliable. I am very disgusted with the unit at this point and cannot recommend this product at all.

4 out of 5 eggsDecent little mini-array.

Pros: I used to use these at work, I missed having it, so I purchased one for myself. Use it as a mini-travel-RAID array with SSD's. "OK" support, be sure to update the firmware. Works good as a JBOD, or Internal RAID with the Windows Software. I've used it in Win7 and Windows 8 on eSATA, and USB3. With good drives it works good. When you have a flakey drive in the array, it'll make the whole array seem flakey. Decent features in the software, but not too fancy.

Cons: Be aware of the 2 buttons on the back, and to position the device in a good location so you don't accidentally grab it wrong, or bump it and push the buttons. The software isn't super fancy, but informational and has enough features.

Other Thoughts: For the price, 20% off arrays sale, it was worth it. Make sure you update the firmware, and to buy the latest model. Some other sellers are still selling the previous version or selling ones with the older firmware. Overall a decent device for the price.

1 out of 5 eggsBad description by newegg

Pros: None

Cons: Be careful, this enclosure is for 2.5" HDDs not 3.5 HDDs. There is no such thing in the description of the product. Have to pay $15 to return and for restocking fee. Can't believe that. Bad service when it's not my fault. Be aware.

2 out of 5 eggsFlaky, no support

Pros: Small, On board Raid

Cons: Unreliable, flaky, *little support. I really want to love this thing. The concept is great. A small eSata or USB external Raid Array. I had it running in Raid 10 via eSata on an Acer 8943 laptop. It ididn't work on USB 3.0 on my Sony Vaio laptop, It does work on USB 2.0. When I added a 5th Seagate Momentus XT 500Gig drive and configured it as Raid 5, I haven't gotten it to work on eSata reliably again. I think I will get it working, but I will harbor doubts about it. The documentation is useful for dip switch settings, but not much else. The AMS website has some docs, a bios file, but there is no forum or support on the web. I will try sending them an email and see what kind of support they can provide.

This is one of those tech things that really got under my skin and I kept thinking about. I wanted a tiny little RAID array using Momentus XT drives (which are great!). Hopefully it will still work out.

5 out of 5 eggsExcellent Raid Enclosure

Pros: Small, Compact, Fast, Extremely Easy to Set Up. Unsurpassed bargain for the price. Set up with 5 Crucial C300 128GB SSD's in Raid 5, typical direct back-up of hard drive files, uncompressed, 85-105MB/s, Large Video Files 155-185MB/s.
Super Portable Raid Enclosure for 2.5" drives and SSD's.

Cons: Off/On Switch in back of unit, extremely small momentary button. Easy to reset system if not paying attention to what you are doing when turning off the drive.

USB 3.0 has never worked properly, but use only as eSATA external drive. Limited Compatabilty with USB 3.0 chipsets.

Other Thoughts: Can't beat it with anything on the market for a SSD portable Raid enclosure.

1 out of 5 eggsDon't waste your money

Pros: Relatively inexpensive, supports 5 drives. No need for software to configure the RAID option.

Cons: This unit is flaky as can be. I have five perfectly good 750GB 7200 RPM Seagate disks in this thing in RAID 5 and at least twice per day the array has to rebuild itself--not sure if this is a bad RAID controller or an inadequate power supply at fault. The enclosure will also act as if it's been unplugged from the computer, which causes my applications in Linux to hang waiting on I/O requests. USB3 doesn't work well at all, nor does eSATA. USB 2.0 has been the most reliable connection for me, but even that isn't so great.

Blue lights are too bright--should be dimmer and ideally green.

Other Thoughts: If you want to attach multiple drives to your computer, get adapters that let you put two 2.5" disks in a single 3.5" bay and house the disks inside your case, and forget about hardware RAID--do software RAID. At least if your SATA controller flakes out on you, you won't lose your data because your new controller can't understand the old RAID format.

2 out of 5 eggsBE CAREFUL when shutting unit down

Pros: Small
Good software (not needed to use device)

Cons: Serious design flaw! On the back of the unit there are 2 buttons; Button 1 is for power and Button 2 is to reset the device.

Press and hold button 1 to shut down the device
Press button 2 and the device reset (like a restart)
Press and hold button 2 for longer than 2 seconds, and it deletes the array configuration - WHICH MEANS YOU LOSE ALL OF YOUR DATA.

The buttons are about 1/4" away from each other. I encourage all users to double and tipple check that they are holding down the correct button when attempting to shut the device down. There is no warning, no beeps or anything let you know you are deleting everything. Do not simply feel your way around the back of device. Look and make sure the correct button is being pressed.

The reset button should need to be held for 10 seconds, or beep after 5 seconds, or SOMETHING. It is too close and too easy to blow away everything accidentally.

Other Thoughts: Works great other than the serious design flaw. Let this serve as a warning to anyone else who purchases this a device.

5 out of 5 eggs2.5 inch drive model

Pros: small size, price.

Cons: newegg doesn't show anything about drive size, this is for 2.5 inch drives.

If looking to use 3.5 then need to buy VENUS T5C (DS-2350C) 3.5" SATA RAID Storage Enclosure.

Other Thoughts: from AMS web site:

VENUS T5C mini (DS-2250C)
2.5" SATA RAID Storage Enclosure. Powered by the JMB-393 Hardware-accelerated Engine.

5 out of 5 eggsAwesome - Stand alone RAID

Pros: Easy setup , stand alone (hardware raid) , Esata and USB 3.0, Fan is super silent. Easy dip switch selection.

Cons: These are not deal breakers, just constuctive critisism.
Lights are kind of bright and annoying, had to turn the unit around in my media center. Doesn't auto power up with attached unit, you have to physicaly turn it on each time. tray height only accomodates 9.5mm

***(wish to see a future version that would fit 12.5 and 15mm for the newer 1TB and 1.5TB drives.) ****

Other Thoughts: 5 - 500gb hard drives. Works like a champ and fast on my Windows 7 laptop. I have this unit in Raid 5 currently for use with a PS3 (FAT32). The PS3 is usb 2.0 , so not using full potential there but I needed large raid 5 for long-term storage. When attached via Esata on my laptop, I've had windows display reads around 300 MB/s and writes around 150 MB/s. Makes transfering large movies painless.

5 out of 5 eggsHow to enable eSATA

Pros: For a 5-drive array, it is TINY!!!
The price is unbelievable.
Each bay is hot-swap removable.
There's a lock so bumping an eject button won't do anything.
The internal fan is silent.

Cons: It's not the sturdiest parts/construction, but I don't plan to use it as a hockey puck, so it'll last.
The eSATA cable doesn't go in very far - doesn't need to. Visually, it looks like you need to jam it in deeper, which could break something, but it doesn't need to seat all the way in.

Other Thoughts: Dell Optiplex 980 with Windows 7 x64
I checked the BIOS but it was set to ATA. I changed it to AHCI and the computer became unbootable. Repair didn't help.
I put it back to ATA, dis-joined from domain, and ran Sysprep. Then I set the BIOS to AHCI and booted. Windows built back up and booted fine.
Motherboards only seem to allow internal RAID, or AHCI. If you have internal RAID5, then you can't enable AHCI.

Downloaded latest BIOS, chipset drivers, AHCI drivers and installed them. Previous to getting the BIOS set to AHCI, the AHCI drivers wouldn't install. The attempt only told me "computer does not meet minimum specs". But with the correct BIOS setting, the drivers went right on.
Then installed RAID management utility. When I plugged my RAID box in, it was easy to set it to RAID 5 and build the array. Use Windows Disk Manager to format.
Using five 500GB Hitachi drives.
