2 out of 5 eggs50/50 so far

Pros: Around 160 MB/s over USB3.0

Cons: Bought two units... One worked fine out of the box; the other didn't follow the DIP switch setting on the back and would lose connectivity to my PC. Swapped drives and cables with first unit, it continued to fail while the first unit was fine. RMA'd the bad unit, got another bad one in return. Same issue with DIP switch setting and losing connection. Set to 'Mirror', it stripes the disks. Set to 'Combine', it sets the drives to JBOD. Set to 'Stripe', the OS can't see the drives.

RMA'd second unit again. Sending it back this week. Bought 3-year extended warranty for $14 because frankly I don't trust them now.

Other Thoughts: I probably wouldn't recommend the unit, but I see that the black version is one of the best selling RAID units at NewEgg, so who knows...

1 out of 5 eggsYour mileage may very

Pros: 2 Bay enclosure with eSATA port. Supports up to 4 TB hard drives. Has power switch and fan.

Cons: eSATA port does not work with ASUS M5A99FX PRO R2.0 motherboard using the onboard eSATA controller (AMD SB950) in Windows 7 (64bit). Motherboard has latest BIOS and drivers. Windows does not see the unit at all.

Other Thoughts: It appear that eSATA is very very finicky. How well a unit works will depend on the chipset for the eSATA controller. Be warned, you should use either Marvell or ASMedia chipsets or else do not expect your unit will work.

5 out of 5 eggsInexpensive, does what it should!

Pros: Easy to setup (I currently have two 3TB Western Digital Enterprise drives in a RAID-1 in it right now). It seems to be pretty quick (getting around 80MB to 90MB/second from USB3 to USB3). The unit is pretty quiet, solidly-built -- so far, no qualms! Well worth the money, and I'll be getting a second one when the 4TB's come back from RMA.

Cons: None as of yet.

Other Thoughts: I was amused by the inclusion of the non-US power adapters. I think one is UK and one might be... Korean? I'm not terribly sure.

4 out of 5 eggsStarTech Never Disappoints

Pros: Has a small footprint, solid construction and, when loaded with drives, has some wight to it.

Cons: Operation selection of the unit can be cumbersome.

Other Thoughts: I really have nothing bad to say...StarTech has been and will always be my "go to" company for oddball accessories. I had to knock one egg off because of the setup procedure. It should be noted that this is no fault of the product, but of the user manual; or rather lack of. It took some messing around with to get the operation selection I wanted. In short, I discovered that you need it connected to something upon power-on in order for the change to commit. Otherwise it will simply spin down the drives. I was going for a RAID-1 setup and I kept seeing only one drive (as in the actual drive model number) versus seeing it as a RAID device (using eSATA and my controller does not support port multiplication). The best way I found out (if you don't have hot swap support) is to turn on your computer, halt it at the BIOS screen to suspend boot-up. At this point, change the selection switch to the mode you want, hold the "set" button, power-on the unit and release the "set" button. After about five seconds or so, just Ctrl-Alt-Del you computer to restart it and your BIOS should detect it as the new setup. In my case, it changed from the actual hard drive model number (JBOD) to "ATA SSI H/W RAID1 Device". Port multiplier support is only required for JBOD as all other methods are transparent to the BIOS and they never need to see the actual hard drives behind the unit. All other things considered, this is by far a great product. I own two of the black units and one of the white ones. StarTech also makes the black one in a NAS version that swaps the eSATA port for a NIC. They recently released a 4-bay model of the black unit (it only supports JBOD though). I'll probably be in the market for a couple of the 4-bay units for adding attentional drives to my NAS4Free box since hardware RAID is not required. In summation, I would highly recommend this product for the price point it is at.

5 out of 5 eggsStarTech S3520WU33ER

Pros: supports UASP
works in Window 7
works in Window 8
compact design
RAID0 works well

Cons: minor nit is that the front panel LED s/b less intense and the display narrower. definitely an overkill IMHO

Other Thoughts: using TWO seagate 4TB drives in RAID0 mode i was able to get 301/297 READ/WRITE on Windows 8. on Windows 7 i was able to get 264/262 using a Desktop rig with an Asus MOBO with Asus USB3.0 boost 'ON'

i am happy with the numbers. i am happy with this StarTech enclosure and also considering it's distant cousin - the one with the NAS capability.
