Kiley Function: Given that my computer can handle port multiplying for USB and eSATA, this has met all expectations and performed excellently. The drives stay cool, I've no complaints about function. Construction: Solid construction. The drives never jostle (and I port this thing around multiple times per week). The power input, as mentioned by others, is shaped at a right angle and I frequently see the cable bend to undue stress because of it. The lifespan of the power supply will surely be less than the device because of this and the way I use it. The only other complaint I have is the fan. On the lowest speed, mine makes an unsteady, rather loud hum. On high, it's steady and loud as expected. Performance: Copying data from a 5400rpm 2.5" drive on my computer to 5400rpm 3.5" drive in the enclosure, I see speeds around 60-100 MB/s on eSATA and around 25-30MB/s on USB, depending on file size and whatnot. From drive to drive within the enclosure it's usually 90+ MB/s. Please note that these speeds are highly dependent upon my drives, my SATA controller, and various other external factors. I'm glad I bought it. 20 of 21 people found the following review helpful. Good Value, No Sleep/Idle for Drives, Not for NAS Backup By Paul This is a fantastic value. For under $100 (as of 2/2011) you get a solidly built, compact, 4-bay SATA enclosure that supports both eSata and USB 2.0. There are a couple of downsides to the Mediasonic 3.5-Inch USB 2.0 and eSATA Pro Box 4-Bay Enclosure HF2-SU2S2 (Black): * Although there is a sync mode that will turn the unit off or put it to sleep it only works when the device is connected to also goes to sleep or gets turned off. That's fine if you're using it with a PC but with a NAS it means that it stays on all of the time with the disks spinning. That's a waste of disk and energy if it's being used once in a while. * There's a *really* bright blue activity light that will easily light up a room at night and is even visible from the street! * The power connector is on the side. Makes for messy wiring and is kinda annoying. You should also know that your host sata interface needs to support multiplexing or you'll be able to access the first drive via sata (not a problem with USB). That's just a limitation of this product and it's clear from the documentation. Just an FYI. 6 of 6 people found the following review helpful. Amazingly small foot print! By rbhatta This thing is amazingly small for an enclosure that holds 4 SATA Hard disk drives, I am truly impressed by the build quality of materials and workmanship, Installing Hard disks is easy just attach the handle with screws that they provide (Hey they even give you a screw driver!) and presto! You are ready to use your hard drives via USB or ESATA interface. Accessing all the 4 drive bays using USB 2.0 interface is no big issues, Most of the operating systems will directly support this without any need for additional drivers. However, if you plan on using the ESATA interface you will need to plan and attach this to an ESATA port that supports Port Multiplier w/ FIS-based switching in order to access 4 HDDs simultaneously. Some newer motherboards easily does this, Please do some research with your motherboard documentation and or update the drivers for your onboard SATA/ESATA interfaces to support this feature. If you motherboard does not support Port Multiplier w/ FIS-based switching in order to access multiple HDDs simultaneously, You can buy a PCIe or PCIMCIA based add-on controller card that must explicitly say that it can support Port Multiplier w/ FIS-based switching in order to access the 4 HDDs simultaneously. Amazon sells a lot of these cards for various applications (Desktop PC or Laptops) Desktop solution : one of them is Syba SD-SA2PEX-2E PCIe 2x e-SATA Ports with SIL3132 Chipset, if you want just RAID 0 or 1 or if you want more
