How fast is the writing speed?
263194
I am using an older desktop computer and with a USB 3.0 card installed into my computer. Testing speed using HD Tune Pro and a 2GB file I get a write speed 105 MB/s and a read speed of 130MB/s. You will never get maximum stated speed as this is faster than a mechanical Hard Drive you would need a SSD Drive for maximum speed. I purchased the 64GB Version late 2013 and use every day and never had a problem and love the speed.

The writing speed is said to be 190 mb/s and read to be 245mb/s. Looking at reviews this seamed to perform very well and close to the statement. I did a lot of research and found this to be the fastest at the time without spending over $150. I bought this one for my bro in law and I have the 32gb and both are really fast! I can vouch for the 32gb going up to 145 mb/s write I saw it when transferring a larger amount of pictures once. However the 64 is supposed to out perform the 32, either way tho, I doubt you will be disappointed. Evey person that has one of these that ik personally and online are more than satisfied!

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.

I am using USB 3 and performance is reasonable. Using Windows 8.1 Storage Spaces with full parity, I am getting ~20-40 MB/sec throughput on writes. I would recommend it for archive and backups. Not sure about the throughput yet for something like an active media server.

I believe it reflects the speed of the card. The higher the class the higher the write speed.

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!

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.

Much faster than our previous Canon. It seems instantaneous. I believe there is a data point within the Specifications that actually documents it.

Well, I have a test tool, that shows 233.7MB/s write and 319.0MB/s read with a SSD drive in an USB 3 enclosure via an iogear USB3 hub.Most USB sticks, or SD cards are way slower than this.The USB3 hub disconnects, when Yosemite goes to sleep. Then via eSata it copies 1.4GB in less than 5s to my backup drive, not sure, if my drive is a bottleneck, but I am happy with the speeds.

It's OK if you write slower and more deliberately. liek the rest on here said, some lines can disappear. it works OK if you don't scribble fast

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

I'd say about 2-3 seconds. It's very quick, but not instantaneous. I've never used another recorder that goes faster though.

I dont know the speed but i know it's very fast. I already have bought 2 of them

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.

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.

This particular drive is USB2. You'll get about 16 megabytes per second write, 20 to 30 read, depending on file size, fragmentation, etc.

I agree with Gilberto. No problems with speed or writing. It is a good machine.

It just means the write speed ....how fast the CD can accept info from your computer..
