Backwards compatible with USB 2.0; External (Plug Powered) Hard Drive.

Here's a review from an Amazon customer:


4.0 out of 5 stars Useful capacity now matched with a useful speed, 9 Dec 2010
By Dr. D. M. Hunt - See all my reviews
(REAL NAME)
This review is from: Verbatim 47659 USB 3.0 External 3.5 Inch 2TB HDD (Personal Computers)
I have a multitude of external USB2 and a few eSATA drives, on the lookout for a couple more drives, I thought I'd give this new fangled USB3 a go.

The drive is fast, I compared it to a USB2 drive, the data rate starts at around 130Mbyte/s and declines to around 80Mbyte/s at the end of the disc.

A Western Digital MyBook on USB2 started at 22Mbyte/s and ended at 22Mbyte/s.

This drive takes about five hours to format, vs. nearly two days for a USB2 drive of the same capacity.

Another interesting point, the CPU utilisation for the USB2 was around 10% and it was 0% for the USB3.

My only gripe with this product is that the cable is very short, a one metre cable should be standard, but it comes with what looks to be a 50cm cable, so it gets four stars.

Nice price for a usb 3.0 2tb.

I'm still waiting for the price to drop a bit more before moving onto usb 3.0

Still hot from me though :)
#2
would it be 100% compatible with all my USB 2 ports?

Yes, backwards compatible with USB 2.0

Higher transfer rates (up to 4.8Gbps)
Increased maximum bus power and increased device current draw to better accommodate power-hungry devices
New power management features
Full-duplex data transfers and support for new transfer types
New connectors and cables for higher speed data transfer...although they are backwards compatible with USB 2.0 devices and computers (see further detail in article below)


Here is a useful article that excerpt was taken from:

Good price I paid £110.46 for the same one a fortnight ago, very fast, I also purchased a USB 3 expansion card at the same time, it makes transferring video much much faster.

Loving this part of the Amazon review:

2 days!!!!!! something wrong with that guy's computer!!!!!!!!
#7
I've seen PCI-E USB 3.0 cards around if anyone wanted an upgrade without a new motherboard...

how fast? I've heard many people have complained that they cannot get anywhere near the speed it should do.

I'm not putting this down at all just nice to get another opinion..
#9
results are same as previous usb standards, no where near the max, usb 3.0 =4.8gbs but about 4-5x faster than usb 2.0 so still very much worth the upgrade for a 2tb drive.

Aren't those simply full format times as opposed to quick format that most people would use?

That's a good price for a 2Tb drive let alone a USB3 one! Hot.
#12
! see they also do it with the USB3 card for £113.
#13
yep, a proper format would take a loooong time.

cold on these as they dont power down with the computer....for the cost of a relay tut
#14
Good price, but for desktop units I'll stick with esata for now.

This is a good price for a 2TB External HDD so voted hot BUT

Usb 2.0 interface is NOT a real bottleneck for standard HDDs !!! - write/read time is the problem.
Do not listen the marketing trash - USB 3.0 alone is not making the HDD FAST, it's just newer generation of disks that makes you feel the difference.In standard, Usb 2.0 enclosure, the same disk would perform similarly fast ...or even slower :)

The same hard dive with difference interface :

USB 2 only supports upto 480 Mbit/s (60 MB/s) and even the 5400rpm Sammy F3 will hit nearly twice that on sequential reads.
#17
You are right Gavin and I am wrong, at least to some degree.Many other tests show that the differences can be bigger than the article suggests, however they are nowhere near the declared '10X faster than standard HDD' speed .I do not think any would notice a massive speed increase, especially that the disk will be noticeable quicker in some tasks only, most of us use the external drives as storage space and the internal Sata hdds will still be faster

So if i got one of these and the PCI-E USB 3.0 card would i get the faster transfer speeds or would my Internal HDD have to be USB 3.0 ? because the one ive got is USB 2.0

Yes what the standard supports and what is achieved is a totally different thing. In theory if you had a fast enough SSD then there is a small possibility you could hit 10X as fast on a sequential read. But how often will people use it for large sequential reads, very rarely if ever.

USB3 will be big when it's on mainstream laptops and external notebook drives.

You internal drive will be SATA not USB2. If your using desktop and want an external drive then get a esata backplate and a esata caddy and then buy a drive. At this point in time it is a cheaper and faster option. :)

They come with a program on the hard drive called "Green Button" which powers the drive down after 10 mins non use. Also has an on/off switch on it
#21
cheers for the heads-up - been looking at upgrading from the single Verbatim 1.5TB external I have now - this was too good a deal to pass up and got 2 of them

Neither of which are much use when it's hooked up to a media player or wii and hidden away like I had it. I use an internal drive on my pc which is cheaper and makes more sense, for portability I use a 2.5. Pointless product IMO
