PROS: Really can't give this a rating, ordered it for my DVR to external HD, the port on the back of the DVR said SATA, tuned out to be eSata. Kept the cord in case I ever need it. See caveat below.
CONS: When I orderd the eSATA to eSATA cord it looked like it was manufactured by the same company Monoprice got the other one from, it didn't work, I RMA'd it and the replacement worked, although I only tried it I am not using it, I got the more expensive one from them, was about $5 that works great. So I do not have great confidence in this cord ever working, being it is the ONLY SATA to eSATA Monoprice has, I will get a replacement from someone else. This and another SATA cable is the only cables I have gotten from Monoprice that weren't superior to all others, My HDMI cables are rock solid, but I think they better look into another supplier for these SATA cables, I notice other people are having problems with them. Also it took 8 days from the time I ordered it till I got it, I think that is too long, especially when I pay for the shipping. As bad as USPS is, it should still only take 2 or 3 days to reach me, with a day for processing. When I get free shipping from Newegg which is also in California and they use USPS I get my order in 3 or 4 days, 1 or 2 days if they ship from their NJ site.
This thing works perfectly. There isn't much to say as it a straight forward cable. Exactly what I needed to test my new hdds without having to open up my computer. Previously I was using a sata to usb thing but that is limited to 2tb, so I needed another solution to test my brand new 4tb hdds. This cable fit the bill perfectly. One end plugs into your esata port and the other end is regular sata to plug into the hard drive. You'll still need to power the hdd tho so keep that in mind when ordering. Maybe Monoprice could look into supplying an external sata power adaptor as well. Locally a cable such as this sells for $10-$17! And nobody has stock so it sill needs to be ordered and shipped. I'm extremely happy.
It used to be that when you purchased a PC, it had plenty of room for adding cards and drives. Nowadays, while the motherboards typically have 6 SATA ports, there is no room in the box to add extra drives. Solution, use these cables to connect External SATA disks and optical drives.
The transfer speeds achieved using this cable were faster than when I used USB 3.0 however, shortly afterwards I discovered that the eSATA function of my external HDD is faulty and inconsistent. It was excellent while I had the chance to use it! Highly recommend!
PROS: - Excellent transfer speeds - Lightweight and flexible
I'd been meaning to try out the eSATA port on my new motherboard for a while and finally picked up this cable. I already have a hard drive dock for day-to-day use in backups, however if you have a large, non-incremental volume of data to get off a bare drive, this is much faster than USB 2.0 speeds. I get ~127 MB/s via eSATA vs about 22 on my dock.
PROS: eSATA speeds, nice length.
CONS: It's a cable... it simply works. Pehaps just a bit thick and stiff but that is incredibly nitpicky.
