What speed does this card write at? (mb/s)

Bonnie, Here is what I found. http://www.kingston.com/datasheets/cf_us.pdf This doesn't answer your question directly, but these work great and are reliable. Good for the price.

Just got the 128GB version. Running Crystal Disk Mark 64bit - Sequential Read: 100.7MB/s Write: 100.8MB/s 512K read 25.2MB/s write: 57.11MBs 4K random read: 0.263MB/S write 0.943MB/s 4K random QD32 read: 0.457MB/s write: 0.694MB/s - Hope this helps everyone to decide!

It will only write at a slower speed, due to it not being USB 3.0, but it works well. If you only have USB 2.0 port, then this is a good Stick, I own several. Plus I installed a USB 3.0 in my PC, a good upgrade for less then $30. easiest way to calc speed and look at an ad, for USB 3.0, it will say how much faster then USB 2.0

From Sandisk's website for the Extreme Pro:write speeds up to 90 MB/s** (600X) and read speeds up to 95 MB/s** (633X) . The caveat and double asterisk is that the speed may be limited by your camera. They work just fine in full-frame professional DSLRs.Extreme Pro are much faster than Extreme cards. It varies by specific card by the rated speeds may be 1.5 to 2.0 times faster. You can see the specs on Sandisk's website. Their website also has a device-recommendation tool where you can get a recommendation for your camera or other device.

The maximum theoretical throughput of Tbolt is 10GBps. The overall speed of the reader depends on the device being read at USB3 or sata and that depends on the card.

I dont remember read/write speeds, but it is fast. This is msata; there isnt room for an adapter internal. Adapter would work external while cloning.

I think its the fastest CF card you can get, its 800 Mbs per second. whereas Sandisks are only a fraction of this speed

Yes. I have a Sandisk Extreme Pro 128GB UDMA7 card rated at 160MB/s. On this reader, I'm getting a whopping 50MB/s. junk.

No its 480mbps high speed 2.0. I like it as its easy to install and works with windows 7 and I have 3.0 on my motherboard and to tell the truth I copied several files from the computer hard drive to a external hard drive and several were over 1 GB and I could not see much difference in speed and the external drive is a USB 3.0. That card does everything I wanted it to do and I have no complaints, its worth the money.

A regular harddrive reads and writes about about 80 megs per second, this drive does it at around 400 mps. Its really impressive, but you need to make sure both the drive and the computer its connected to have SSDs and thunderbolt to take advantage of the speed.

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.

I use a high speed 64gig no problem. I have read that some have trouble with slower cards.

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

Yes 48mbps is pretty fast. I didn't use it for mac or S5 but I think it would probably work fine with them as memory cards work with all devices

Also note that most vendors spec there devices in MB/s instead of Mb/s. The AX100 outputs about 60 Mb/s which corresponds to 7.5 MB/s. Class 10 asserts that the card supports 10 MB/s as a minimum non-fragmented sequential write speed and uses a High-speed bus mode (from Wikipedia). So technically all class 10 cards should be able to sustain the requirements. It does require exFAT format.

The card readers are all USB 2.0. Running a benchmark on a Class 10 SD yielded typical transfer rates of 30-35 MB/s.

I have this: 30 MB/S is printed on it, pretty fast. Purchased a SanDisk Extreme 80 MB/s for my new 70D also, but cannot sense the speed difference of the two cards in the camera.
