Someone reviewed and wrote its writing speed max at 12 MBPS, is this True? That is TOO slow to use. Even USB 2.0 is 20-40 MBPS.

I get ~30-40 MB/s via iSCSI (NAS' CPU is maxed...) with all other services disabled, can't comment on SMB performance since I dont use it. These are definitely not the fastest units. (for anyone else reading this, that is megaBYTES per second, not megaBITS)

I will test it tonight and see. Last time I checked though it performed at good speeds. But I am only using a 4700rpm drive so I may be maxing out the read/write on it anyways. But from my experience it performs a lot better then 2.0. Also another note is that if you plug this into a 3.0 port you don't need to use the extra USB cable for power. The 3.0 port can put out enough juice to power the whole thing. I didn't know this before I bought and honestly wasn't a big deal, but helpful to know now.

I just got one of these to back up the data on my Win8 laptop. It's as slow as MUD. I connected an external hard drive to the SAME USB port, and it was FAR faster. Avoid at all cost.I'd suggest this as the best alternative (get the 64GB for $50 rather than the 32GB for $45): Mushkin Ventura Pro 64 GB Flash Drive. It is USB3 but works very well on USB2 (and it's fast there too). One Xbox 360 user said it works perfectly (read the comments). Here's the link: Mushkin Ventura Pro 64 GB Flash Drive - MKNUFDVP64GB (Black)

I'm not 100% tech savvy, but I think the major difference would be speed, if I'm not mistaken. 3.0 is the latest standard, isn't it? I think the transfer speed makes the difference, in which case I don't mind this one because I don't have any 3.0 USB items....I'm not much help in this matter, I just needed extra ports because I've downsized from a desktop to a laptop temporarily, so when I saw this I just grabbed it. It works quite well for what it's worth. I'm sorry if it this doesn't help.

Yes. It is actually rated for USB 3.0. USB 2.0 is only a data transfer rate. 2.0 can transfer 480 Mbits/sec. USB 3.0 (which is what this is rated for) transfers up to 5 Gbits/sec!

It appears that the Writing speed is about 5.60 MByte/s and the reading Speed is about 7.37 MByte/s. This is based on some of the tests I was able to run on my PNY Attache III 16 GB USB 2.0.

in theory - if you are using this flash in a usb 3.0 port you will be getting 10x the speed 625 mb/sec vs. usb 2.0 60 mb/sec.. If you are using this in a usb 2.0 port you will get no speed advantage. also in reality there are many other variables that will affect your speed. all in all though I am very happy with the speed I get in my corsair voyager 3.0 mini and its' tiny footprint is very nice also.

These drives are kind of strange. It transfers off the drive at high speed (~20 MByte/sec) but only writes at ~2 MByte. So I think it's USB 2.0 but the internal flash management chip on the drive must be pretty inefficient so it can't keep up with the comm. speed when it's doing write operations. Delete operations are also really slow. So overall I probably wouldn't recommend this product. I got them because they were cheap and I don't need high performance for what I'm using them for.

I use a 16 GB tab on a mac laptop, USB2, OSX 109.3. It's fast enough for me. I mostly store very small documents on it. i tried a 947 MB file; took 2 minutes. a file speed tester a tried yielded speeds all over the place: write 5.5 to 9.6 MB; read 16.1 to 34.9 MB.if you want large files to transfer fast, try a Patriot Magnum. Mine is USB2; it's honkin' big, but i copied the same file in 30 seconds.

From: PC: Intel Core2 CPU 6600 @ 2.4GHz (Windows 7, 64-bit) Port: USB 2.0 Card Reader/Writer: Kingston's MobileLite G3 To: SanDisk Extreme Pro 16 gb And an IMG file (2,478,505,984 bytes) I can reach 27 mb/second Note 1: maybe with a USB 3.0 port you can reach a best speed. Note 2: maybe without an adapter you can reach a best speed.

Sorry, I made a mistake. The USB 2.0 read speed is 30 megabytes/sec and the USB 3.0 read speed is 255 megabytes/sec., i.e., bytes not bits.

My benchmark using CrystalDiskMark shows its sequential write speed is 12MB/s. That means it meets class-10 requirement.

With USB 2.0, it'll move roughly 16 MB/ second. With USB 3.0, it'll move roughly 28 MB/ second.

USB 2 rated at 480Mbp/sec. I know of no way to modify a Macbook pro for USB 3.0 if it is not already configured for 3.0. Hope that helps...

I had the same question so I spoke with a Canon rep today. He recommended SanDisk but noted that the sd780is only writes up to 18-19 MB/sec. So it's essentially a waste of money to purchase a card that writes any faster than 20 MB/sec. Check this one out: Sandisk 8GB EXTREME SDHC SD Card Class 6 (SDSDX3-8192 Bulk Package) However, faster cards are likely to write and read faster through a card reader or on your computer.

Leef Surge USB 2.0 64 Write - up to 15 MB/s; Read - up to 28 MB/s. Thank you

Based on when this was introducer, I doubt it's USB 3. If your internal storage is either flash or SD, it really doesn't make much difference whether you have USB 2 or USB 3 port speed - the storage element write speed will be the gateing item.
