Armor for Your Data

Protection Against the Elements

These drives are called "Armor" for a reason--they're protected against nearly anything you can dish out, even the unexpected. The Armor A80 is compliant with IPX7 waterproof standards, meaning it can be under a meter of water for 30 minutes and still function fully. It's also dust- and pressure-proof. That means your data is safe from unexpected spills, rain, dustier spaces, or most any other environmental concern.

Military Drop-Test Compliant

The Armor A80 is also compliant with MIL-STD-810F 516.5 procedure IV, aka the "transit drop test." What does that mean? It means the A80 was tested for direct drops onto concrete floors or harder surfaces, and (on a drop-test machine) freefalls from a height of about 48 inches. 26 contact points in all are tested (8 corners, 12 cut surfaces, and 6 major surfaces).

Ultra-Fast Transfer Speeds

Armor A80's outstanding read/write speed is coupled with the latest USB 3.0 interface (backwards compatible with USB 2.0). The USB 3.0 interface features a 5 Gbps/sec bandwidth, ten times that of a USB 2.0 interface. It saves users precious time backing up to (and from) the hard drive, and makes transferring giant files a snap.

Easy to Use

The Armor A80 design makes it a breeze to use. Easily take it wherevery you go with a convenient cable carry design. Plug and Play operation means it's recognized as storage by your computer with no additional drivers required. No "wall-wart" adapter is required, either, since the drive is powered via the USB bus.

I work as a Karaoke DJ and tend to keep all of my music on an external hard drive. The problem with that is people spill drinks and get clumsy around equipment when they're drunk. So, I decided to do some research and look for an external HDD that would be able to support the large volume of music and at the same time present me with the comfort and confidence in knowing I have an external HDD that will withstand "torture".

I ordered my A80 1TB HDD on February 13th and it arrived February 16th. So, right off the back their was a prompt and quick delivery of the product. When I opened the package I was very pleased to see the sleek, clean, ergonomic design but at the same time I could tell that this unit holds a solid quality feel. It comes with 2 USB 3.0 Super speed cables. 1 of which rests beautifully inside the side of the HDD case. Not only does the Silicon-Power A80 use the Asmedia AS1051 processor they are also one of the first USB 3.0 chipset certified manufacturers. Silicon-Power promises that this unit meets the water resistant standard and the U.S. military drop-test standards. I will run both the drop test and water test on video for this review.(COMING SOON)

Before I run the drop and water tests I wanted to run a Benchmarking test. So, I used HD Tach. Now remember, anyone running any benchmark tests must understand that the mileage depends on hardware configuration. Basically, what type of computer hardware and software setup you're running.

I'm running:

Windows 7 Ultimate Service pack 1 32Bit OS
2.67 GHz Intel Core2 Duo

First thing I tried to do with this drive was copy over 27.6 Gigs worth of movies. Average write speed was ~70MB/sec. To my surprise, some files were "too large" to copy to the drive. As it turns out, those files were each over 4 Gigs..meaning I needed to convert the drive's format (from FAT32) to NTFS to handle my >4Gig files. I did so simply by going to the command prompt and giving the command "convert d: /fs:ntfs" (I converted d: because that's the drive letter associated with my Silicon Power drive) After I converted to NTFS and did the same copy, I saw average write speed of just over 100MB/sec. Very nice. FYI: The system I did the copy from is Windows 7, 64 bit.

This drive is a bit bigger and heavier than the Seagate FreeAgent GoFlex portable drive, which for some reason was a surprise to me. I haven't had a chance to test its durability, but it looks/seems pretty tough, the casing is metal, not plastic. I bought this drive together with this Case Logic case:
Unfortunately, the case is just a little too small for the drive..still the case is quite nice, so I will keep it.

Overall, so far, I am really liking this drive.

I've been wanting to get one of these Armor A80 for awhile, finally got around to it. First off I really like the design of this hard drive, it is looks extremely simple but looks good and feels very sturdy. The small cable enclosed on the side is extremely handy.
Just got it the other day and already unintentionally tested the ruggedness of this hard drive, I went rock climbing and the A80 was sitting in a little pocket in my backpack when it fell out. It was about a 80-100 feet drop and at that time I didn't even know it was the A80 that fell out, I thought it might been my bottle or something else. When I went back down I saw the A80 on the ground and I was like "crap"... I usually take out everything from my backpack before I go rock climbing but in this case I forgot.
I brought it back home thinking it's most likely not going to be working anymore after a 100 feet drop onto solid ground. To my surprise it ran like nothing at all happened to it, all my files were still there and no weird sounds or anything. I'm amazed, I haven't tested if it submerge in water but I assume it can, this is one heck of a rugged hard drive.
Also another amazing perk is that Silicon Power is doing a promotion on their face book page, you get a $15 Amazon gift card if you buy it now until early February I believe. I just sent in my invoice so I should be getting a response soon. If you buy one I recommend you searching for silicon power usa on facebook, you have to be a fan and then you can send in your invoice for a free Amazon gift card.
Forgot to mention that the case did get a few dents from the drop but not as bad as you would expect from a 80-100 feet drop onto solid ground. I will try to see if there are any cases for this hard drive, keep you guys updated.

Well...I dont know if I can officially call it an upgrade, being that I own a few Seagate drives and have never had a problem with any of them. But this drive is neck and neck with my Seagates.

I love the color. It's the same color as my old motorcycle. Looks great along side a Macbook (which also was the same color of my bike....ok....ill stop now.)

I was worried this drive would be a bit too heft because of the added real estate for the additional hidden wire, but it really is not a problem. And it's also not as thick as I thought it was going to be. It is still bigger than my GoFlex, but since it has about 650 more GB than my GoFlex, I wont complain.

Also, the 'hidden wire' seems to stick out a little bit. I can never seem to get it fully hidden in the wire storage area, but its not enough to be annoying.

I am very careful with my electronics, so I dont plan on dropping or spilling anything on it, so I didn't really care so much for the military specs. More so than anything, I needed a 1TB drive that was small, and I loved the fact that it had the integrated wire that can be stored. I was going to go with the BUFFALO MiniStation Extreme 1 TB USB 3.0 Portable Hard Drive - HD-PZ1U3R Red but after watching some YouTube videos, I didn't like how loose the wiring looked.

Which brings me to reason 2.

I have never owned a USB 3 drive, but I have worked with house wide networking and audio / video installations for many years and for some reason, the new USB 3 connector just do not look that sturdy to me.
