Pros: Compact, lots of features

Cons: None.

Overall Review: This is my third of these front panel solutions, all three of them installed faultlessly and all three are attached to internal USB 3.0 interfaces with faultless performance. I've only setup hot swap on one of these installations and after a bit of messing around it works well. On my messing about rig I use the 2.5" drive to swap in and out different boot drives with various OSes I mess around with. A lot easier than constantly changing boot order in the BIOS.

Pros: This is the single most useful computer accessory I've purchased in a long time. I've been using eSATA docks for years, both to retrieve data from drives of other computers and for my own emergency preparation. This is a great improvement on the concept of a dock. I have a three disk ZFS mirror on my system; one disk is now in this dock instead of sitting on an external dock. In the event of an emergency (such as an earthquake), I can just pop out the drive & off I go. This is nicer than an external dusty dock & drive, plus there's no external power supply or cable necessary. Both the 2.5" & 3.5" slots have their own SATA connector & they share a power cable. Each supports SATA III and can be used simultaneously, along with the USB ports (of course). Each bay has its own ice blue LED to indicate a drive is inserted, plus the LEDs flash purple when the drive has any activity. The blue LEDs are a bit bright, but are small & nicely integrated. The USB 3.0 connector is only for a USB 3.0 motherboard header, which is obvious from the photos & web pages. I'm surprised people give it bad marks because of this, because it's clear before you make the purchase. This is something I wanted, because my Intel dq77mk motherboard has the appropriate header and I of course had to plug something into it.(!) I have found at least three versions of this product, each with a different face plate but the same guts. There are no drivers necessary for this--just plug it in. Even if I ran Windows, this device requires no drivers and no special software. The three versions of this product that I have found are below, and the prices can vary quite a bit. It depends on your aesthetic preference, and if you want one, two, or zero locking bays: Kingwin KF-253-BK Thermaltake ST0026Z Syba SY-MRA55006

Cons: None to report

Pros: Solid build quality Mainboard USB 3.0 connector and 2 USB 3.0 ports Power button for Hard Drives. Great for hot swap capable Motherboards

Cons: A tad high in price. I bought the second on sale plus a 10% off bitcoin code. Dollar cost averaged to be a decent price for both units.

Overall Review: Very please with the purchase. I have always had removable hard drive bays in all my main PC's ... now I have that bay "Plus" one for a 2.5" drive so I have swapables between desktop and the DVD-HD-tray Laptops I use. Considering you get a motherboard USB 3.0 connector with 2 USB 3.0 ports ... in the right situation this is a very good deal. My case was an older case with a newer Mobo ... so it worked out well for me.

Pros: One bay take care of Hot Swap 2.5" and 3.5" HDD and USB 3.0 socket.

Cons: No fans to cool the 3.5" HDD. I put in WD Green 3TB for backup files, the file copy process could make the HDD getting hot. There is a hole that could permit to install a 40mm fans at the back to pull out hot air. Would like a lockable bay for both 2.5" and 3.5" bay to prevent accidental take out the HDD.

Pros: -accepts both sizes of sata drives -dual usb 3.0 ports -easy install -aesthetically looks good in a black case -makes inserting and removing sata drives for a system really easy. great for doing stuff like backups when you don't need to keep the drive permanently installed.

Cons: -the locking mechanism for both drives take a little bit of pressure to close all the way when a drive is being inserted. hardly worth mentioning. -the LED for when a drive is being used is like a purplish color. Why not red like most other HDD activity lights?

Overall Review: Would probably work fine for all motherboards, but if you need the ability to hotswap (keep computer on and insert/remove drives) then make sure the motherboard supports sata hot plug. I use an MSI x370 Gaming plus mobo that supports this feature.

Pros: After a few years, I can now confirm how reliable this drive is to read modern HDD as well as laptop HDD. Fantastic add-on for USB3 connections on my Asus z97 wifi. Great features like on/off switch. Hot swap, etc Perfect mechanism for inserting/reading drives

Cons: - None

Pros: easy to install, works as expected, looks nice, extra usb 3.0 ports, sata cables included

Cons: not really a con, my fault for assuming this but i thought that both bays would work on one sata cable, they don't you will need 2 sata ports available

Overall Review: make sure you have an empty usb 3.0 header on your motherboard, would buy again but hope i won't have to

Pros: use these to clone drives they work well

Cons: none
