I've had this eSata/USB 3 case for a 9 year old Bought an old Dell laptop. This Dell N5010 (8GB RAM - a cheap $20 upgrade from 4G) was very productive but held back due to slow USB 2 for backup. Since I like to drive my computers completely into the ground until it's time to move on, $48 for more functionality seemed like a good idea. With eSata (USB 3 cannot be used simultaneously and I don't have a USB 3 port anyway) I tried speed tests with "Crystal Disk Mark" on different drives. My main laptop drive is a Kingston 250G SSD (another cheap $50 upgrade that REALLY improved program load speed - booted WIN 10 in 5 seconds. Win 10 Pro 64-bit upgrade was free from MS and is still)). A short history of plate reaction with two different plates. The new WD Black 500G 7400RPM CMR drive was decent at about 60% read/write speeds of the Kingston SSD. The 128GB Samsung 850 PRO 4-Year-Old SSD absolutely outperformed the Kingston SSD by 20-1000% in every read/write measurement when connected to eSATA! Blow me away I've tested other hard drives/flash drives/flashdrives but WD and Samsung PRO were the most revealing as I expected the others to be slow. If you have an old box and want to expand it a bit, this is an option. with the other items mentioned. When upgrading to Win 10, first check the BIOS to ensure your eSATA connection is enabled. Otherwise working with WIN 10 (blue shit screen) and eSATA working is a royal pain. Another reason I bought it is that I can then use it as a fast USB 3 drive when I connect it to other computers with USB 3 ports. This element allows for a bit of future proofing, if you buy an old system like mine then eventually upgrade it.
