This is great value.As per other reviews here, I am astounded at the build quality and inclusions with this product. It comes with a couple of dozen little drive screws, which you would only need if you are installing 2.5 inch drives. And it comes with cables for both eSATA and USB 3.0, and they are not the usual short cables that come with drives - there is a little room to play here. I did not measure them but they are good. The POWER cord is only a couple of feet long, but it is a standard 3-prong IEC power cable! You can get one cheap anyplace you are, if you don't already have a couple of spares lying around.The RAID app is fun! I spent the day changing modes and testing speed. I've had RAID appliances before, but I'd never ever built a RAID, and it was pretty easy with the included software. I have to not that I used the software to set up my drives in it. I had an old Promise 6400 4-Bay enclosure from 2009 I think, and bay 4 was crapping out, so I took a chance on this Syba box to replace the failing Promise. I had the most recent 4x 5TB hard drives from that box, and a fifth 5TB drive I had as a spare, so in they went, and it's running fine on my Mac Mini 2012 running El Capitan. I am going in through eSATA into a Thunderbolt-to-eSATA dongle I had used with the Promise RAID. I'm currently running in RAID5. In every mode I was getting about 200MB/s up and down from this thing. It's a great box so far. If anything changes I will update this here review. Have a great day everyone!Update: a week into running this. The unit is fine, but the HW RAID Manager software for Mac now cannot see the enclosure, although the RAID volume does still mount perfectly on my desktop. I switched from eSATA to the USB connection to see if it helps, but it didn't change anything. I deleted the software management app as well as all of it's prefs and did a clean reinstall, and it still doesn't see the unit. It turned out that if I launch the application from my DOCK it won't see the drives, but if I launch the application from inside the Applications Folder the app operates correctly!! So do it that way, and all will be fine. The RAID Hardware is exceptionally well constructed, accessible, and runs very cool temperature-wise. I'm loving this thing!
