A question about usb 3.0 keys
January 28th, 2014
And I’m wondering after searching a while, why are usb 3.0 keys… Such scams ?
I mean c’mon, usb 3 can handle in theory 400 mob/s, but the keys can only write at 20mo/s and read at 70mo/s therefore, being useless as a usb 3 product. 2 would have been fine, and prolly cheaper of course :p
Then again, maybe I just didn’t find the good ones, I got tired after a few hours or searching and laughing really hard.
So, d’you know any worthwhile usb 3 keys which serves my purpose, with at least 16go storage ?
I’m getting so annoyed at transporting my old external HD usb 1.1, considering it’s weight and transfer speed :p

The flash memory itself that they use is too slow, so there is no benefit from using USB3.
Also hard disks are limited by the hard disk themselves which only work around 100mb/s. Only an external USB3 SSD disk would be faster.

Yeah, I know all that :p
And that’s why I’m looking for an actual USB3 ssd thingy
Thanks flamingsword too for the try.
But on your links, I can only open the 4th one, (first three are a blank page for me), and well, it’s still a scam.
“Fully compliant usb3 key” isn’t some crap that can’t write more than 70mo/s and read 120mo/s according to their details :p
Guess i’ll be forced to get an usb 3.0 ssd drive, I prefered a key, it’s smaller, but well :p
But note that even a USB3 SSD will not perform near the “400mb/s” that USB3 supposedly does.
Even if the internal SATA speed of them is around 500mb/s, the fastest I have heard of in USB3 version is still just a bit over 200mb/s
Moving.
@Elrad135 – do you even have a USB 3.0 card on your puter or notebook ?
My Mushkin Ventura Pro can read at 125MB/sec and write at around 70MB/sec.
Ive got a couple of Kingston DataTraveler Ultimate 3.0 G2 flash drives (a bit on the chunky side though)
According to USBDeview, the average read speed is about 100 MB/s and write speed around 70 MB/s.
I certainly notice the speed difference from USB 2.0 esp with multiple image files, it’s not as fast as claimed, probably 4-5 times faster than USB 2.0 (but as I mentioned in my post above, that is if you have a USB 3.0 card in your puter)
Oh sorry, I only look at the “off topics” subforum here, therefore I posted there :p
Took me a while, thinking my topic had been deleted when I couldn’t find it there ^^
So to answer, in order :
(thanks for moving it to the right section :p )
To squirrelman : Damn… Then again 200mo/s would already be better than the what… 20 mo/s i’m getting from my very old external usb hard drive (must be a 1.1 I’m guessing).
So considering I’m using that external drive at the moment, at the main mean of transfering files from a temporary laptop (loaned till I actually get a working good internet line for the desktop), and my brand new desktop, I’d really like to start NOT taking 20 minutes to transfer the tv series of the day I dl’ed during the night on the laptop.
Yeah I know, 20 minutes isn’t death… But well, Time spent transfering, isn’t really time spent making both computers do funny stuff
To gilly : I could simply answer “Yes” But I never brag enough about a brand new computer… Most of my friends don’t have the slightest clue about what a “less than 20 year old computer with something better than windows 3.1 installed” is :p
Motherboard : GA-Z68X-UD3P
Processor : Intel Core i7 2600K (at 3.40 factory setting, but oc’ed to 4.88 thanks to the free utility from the motherboard makers)
Ram : 16go, PC 12800
Hard DriveS : Crucial M4 128 go, for the OS / A good old (well yeah, only part of my previous computer I kept…) 2 to Hard drive. Caviar Black I think was the brand… / 3 times Seagate Barracuda 7000.12 SATA 3 – 1000 Go too. (so yeah, about 5 To storage :p )
Graphic Card : A little GTX 580 at 1.5 Go.
And of course appropriate custom powersource, tower and cooling
(First time that I’m averaging 30° Celsius while runing a bunch of stuff :p )
Oh almost forgot the only answer you asked for : 3 USB 3.0 ports (amongst a ton of other ones ;p )
And regarding your other post, I don’t see how a 100 mo/s and 70 mo/s hard drive, would be faster with usb 3 than 2… considering that usb 2 can actually handle the maximum reading and writing speed of your hard drive
Making the usb 3… Gimmicky at best.
Are you sure it wasn’t an usb 1.1 before ? you know, the one at 20mo/s max
Sorry about the braging try here… I’m sure quite a few people have better computers than this… I’m just so happy to have, I believe for the first time in my life, such an up to date computer, rather than the 2 year old model I used to buy, which worked very fine even for very recent and demanding games, but not as well as that one :p
Anyway, I’ve been reading tests about SSD hard drives, and I’ve seen a few which reading and writing speeds who would actually push an usb 3 at it’s limits. Only problem is, they were internal drives… With no USB port of any sort obviously
So I was, and still am, hoping there exists, somewhere, external harddrives who are just as good, but with usb 3.
My initial question (before I posted here though) was just a curious one actually, I was just wondering, why they invented usb 3 in the first place…
Since apparently, most harddrives, the affordable ones anyway, barely even use usb 2 at full capacity as far as I can see.
I know, progress and all… But why make people think that the new norm with connections is a must have, considering, it won’t even be needed before years or at least months ?
Am I that naive about capitalism ? ^^
I just don’t see how you could really sell a product, when it’s first target audience, must know (or they really haven’t looked anywhere), that it’s not really something usefull
And regarding your other post, I don't see how a 100 mo/s and 70 mo/s hard drive, would be faster with usb 3 than 2... considering that usb 2 can actually handle the maximum reading and writing speed of your hard drive SmileMaximum speed for USB 2.0 is 480Mbps NOT 480MBps. There is also some overhead. This results in around a max transfer speed of 35MB/sec for USB 2.0.
Making the usb 3... Gimmicky at best.
Isn’t 480Mbps like 80 MBps ?

I wasn’t asking for your puter specs, just if you had a USB 3.0 card in your puter – from your OP you don’t even state that.

Fine Although USB 3.0 cards do have bandwidth limitations, especially if they are eg. only pci-e x1

You obviously don’t know what you are talking about . If you had bothered to Google the item, you will see I posted stats for a USB 3.0 flash drive. USB 2.0 goes nowhere near those speeds.
If you are looking for an external USB 3.0 drive, I have had a couple of these for some time, and they have been reliable.
Seagate FreeAgent GoFlex 3TB Desktop USB 2.0/3.0 External Hard Drive with Capacity Gauge
http://www.amazon.co.uk/Seagate-FreeAgent-Desktop-External-Capacity/dp/B004C0YXH0/ref=sr_1_2?ie=UTF8&qid=1317289773&sr=8-2
You can get them much cheaper than this, I just used that for the pictures for you. It comes with a USB 2.0 adapter (detachable at the bottom), so to use with USB 3.0 or Firewire 800 you need to buy an extra adapter (about £12)
I would point out that the capacity gauge on them doesn’t work though
(You can also get different capacities and NAS versions)
When you get your MBps and mbps differences figured out – you will see that USB 3.0 is faster than USB 2.0
*Edit – If you want super fast transfer speeds with USB 3.0, then just get a USB 3.0 2.5 inch hdd enclosure, and just stick a SSD in it (rather expensive option though) :p
oops – hit quote instead of edit, sorry
Elrad135 replied: Isn't 480Mbps like 80 MBps ?Theoretically. USB requires both ends of the cable to have a “brain”. There is processing involved and therefore (a fairly large) overhead when using it. For example, your USB devices isn’t just NAND flash memory. It will have a small ARM based processor/controller which communicates with the controller on our computers. The total maximum possible link speed is 480Mbps.
oooh, interesting
And Gilly, Of course I have no idea what I’m talking about… If I did, would I be asking the question here ? Well no, I don’t ask questions I have the answer to :p
And you guys explain computer stuff way better than google does, that so called friend only makes me ask myself more questions :p
So, if I understand you correctly paroxysM, an usb 3.0 can only handle like 250mo/s anyway ? (500 split in two ?) and a usb 2, like 40 ? Humm… So I do have an old external HD usb 2 then… Hum hum… I really need 3 then :p
Oh and Gilly, yes I know you didn’t ask for my specs, it was humor, humor Then again, if my comp couldn’t handle usb3, I wouldn’t be asking for stuff to plug in those :p Then again, I fully understand that some people do ask those kind of stupid questions… And I’m sorry for the lenghty braging you didn’t ask
And I never said usb 3 wasn’t faster than 2, I just guessed (not knowing the truth obviously, I now know, thanks ParoxysM :p ) that the hd wasn’t going to write or read fast enough :p
It was dumb, stupid too, yeah, those can coexist in a sentence

asks
Isn't 480Mbps like 80 MBps ?
actually no not the same at all
Mbps – mega BITs per second, as opposed to MB/s, which is mega BYTES per second. usually refered to in internet speed ect.
bits vs bytes, binary ex.00011111 like 8 bits make a byte, 8 bytes make a character, 64 bit, or 32 bit windows, 64 bit reads 8 char at a time 32 bit reads 4 char at a time, if you want to know you can search google or, anyway did not mean to get off topic, don’t mean you don’t know this already, just wanted to answer the quoted inquery, hope i said it right, if not sorry.
usb 3 is good, and will provide way more soon, with the computer you list above, you should be flying speed, usb 2 should be fine for now, usb3 is on it’s way to being great, like the change from usb1 to usb2, it took a while to get it all working
Hum, I do know the conversion rate between Bits and Bytes… Hence why I divided by 8 in that quote
480 divided by 8 = 80 after all ^^
I just didn’t know that as far as usb was concerned, you needed to split it
But even that was answered to me about 3 posts ago
Thanks though ^^

Well your OP was suggesting USB 3.0 is a scam, which is isn’t, because there is irrefutable proof it is at least 4-5 times faster than USB 3.0 (I’ve never seen actual proof it is up to 10x faster as claimed).
Well hopefully, your USB 3.0 card isn’t in a PCIe v2.0/2.1 x1 slot, as you will only get up to 500MB/s each way anyway due to bandwidth limitations
(That’s also humour)
USB 3.0 cards currently aren’t that great anyway and they’re all a bit slower than their integrated brethren.
