4 out of 5 eggsBasic reliable no-frills drive

Pros: Performance is not bad, it works well and seems about as fast as my Toshiba Canvio and WD Passport USB 3.0 drives. Blue light is visible, but not overly bright like many products these days. For the price I paid for this it's about what I expected. A no-frills, simple external drive.

The drive DOES in fact turn off after a period of inactivity but the light stays on so the only way to tell is to put your ear next to it and listen if it is spinning or not.

Cons: Pathetic 1 year warranty tells me HGST doesn't put much faith in this thing lasting for the long haul.. -1 EGG for that

No rubber feet on the bottom means this thing slides across smooth surfaces easily like a hockey puck, but I fixed that by attaching rubber feet I bought at the big box store's crafts section

Other Thoughts: The USB connector it uses is a typical SuperSpeed (a.k.a. USB 3.0) MicroUSB connector. It's not proprietary. Check any other USB 3.0 portable hard drive and chances are it uses the exact same connector.

1 out of 5 eggsAvoid This product

Pros: Considering most External drives are USB 3.0, there are not Pro's about this drive

Cons: Stopped working after two months of very little use. I just lost Gigs of files from my past that i will never get back again... if you use it, do not use this as a back-up device. it will fail you.

1 out of 5 eggsHorrible

Pros: fast, when it actually works.

Cons: i've tried 3 different USB 3.0 cables, but no matter which cable i try, the drive won't even activate. it won't be recognized by the computer, and i can't use it. the only fix i've found is to physically hold it up in the air while i'm transferring files. not exactly convenient.

on top of that, customer service from Newegg has been extremely lacking, and i've received no help. 1/5

2 out of 5 eggsNonstandard cable.

Pros: None, as I was unable to install.

Cons: Packaging from Newegg was a bubble envelope, resulting in damage to the manufacturer's clam shell packaging, though no visible damage to the drive. The socket is nonstandard. The unit comes with a corresponding cable which is only 6 inches long. Windows 7 does not come with a corresponding driver, and my system was not able to download one from Microsoft, probably because I have automatic updates disabled. The maker is Hitachi. Its web site requires registration, and I was not able to find a driver download there in a reasonable time.

5 out of 5 eggsJust what I needed

Pros: Great little drive. Now I can carry all my music collection around (and then some). I take this drive with me to work, plug it into a USP port and can work all day long with music in my ears and not have to worry about ticking off the network admins for using their storage space. After 8 hours of use it is hardly even warm.

Cons: None so far.

4 out of 5 eggsBackup Drive

Pros: Small, Fast, Quiet

Cons: No separate back up software with the unit or downloadable from the website. I had to use my Windows 8 internal software to create the back up. The hard ware is good just missed out on the Software link

4 out of 5 eggsWorks - but is squeaky

Pros: Inexpensive, works out of the box, blue light shows it's working

Cons: Makes little squeaky noises, doesn't seem fast for USB 3.0

Other Thoughts: I've had this drive for about six weeks. A few weeks ago, it started making little squeak noises when it reads/writes. This isn't a problem, but it is worrisome. It may be the design, but none of my other drives do this - just the Touro. It also seems slower than my WD USB 3.0 drive, but both are 7200 rpm. I don't think I would buy this again. I'm hoping it's just a fluke, but I'm getting valuable data off it soon just in case. I would give it 3.5 eggs, if the option was available.

1 out of 5 eggsDo not buy and do not use!

Pros: Cable plugs into the drive reliably.

Cons: I own, unfortunately, several 2.5" Touro USB3 external hard drives.

All misbehave, including this one - 500GB 0S03452. They may drop from the computer's visibility at any time, including during writing a file, or after some time of inactivity. A replug is required, but the newly written files, even fully written files, may disappear. The hard drive never stops spinning, which is bad for laptop on battery power.

The hard drive does not have rubber or any other feet, and slides on surfaces easily.

Other Thoughts: For now, Hitachi's (or HGST's) 2.5" external hard drives shall be avoided, until new models prove functional. The designers' team. evidently, doesn't care about users and doesn't know what they are doing. They just built something that displayed some functionality, like software in alpha stages.

There is no firmware on HGST's web site to correct the problems. There is no possibility to set the sleep time, or adjust other settings.

In short, this external hard drive is a totally failed product. One wonders how many years of professional education and how much quality control is required to produce such a product.

This is unfortunate and difficult to comprehend, since I have used Hitachi's Deskstar hard drives successfully, and Western Digital's external 2.5" hard drives aren't bad at all.

5 out of 5 eggs4 Months, still working.

Pros: The best pro would probably be that it's still working. I've had bad luck with external hard drives, SD cards and flash sticks alike.

It's USB 3.0 but I can't seem to get any speeds faster than 40-45 mb/s even when transferring data from my SSD to it. It's not really a con since it's fast enough for my needs however people say I should be getting around 200 mb/s.

Cons: The light can be a little annoying but that's not really an issue.

Other Thoughts: It's a nice drive. I took a chance when I bought this since it had no reviews at the time but I've always had good luck when it comes to Hitachi. If you need something that's going to break the speed limit this isn't it, but it is reliable.
