Sandisk says "write speed up to 90 MB/s"I did some tests with my USB 3 Card Reader (sandisk brand) Wrote a 4gb file to it and averaged 75mb/s and even faster on smaller files.. PC: i7 2600k @ 4.2 Win 7 64bit

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.

Sony rep states 60Mbs/sec WRITE speed. Be aware that card manufacturers often state READ speed on card so do some research. I have had excelent luck with the Sandisk Extreme Pro 64GB card.

The write speed stays above 45MB/s but that will be more than ample for still photography especially. It's also plenty for HD video or still bursts coming from a DSLR if you are converting this to a full-size SD card.

Up to 90MB/s read speed, 50MB/s write speed. That's what it says in the ad and it may be right. All I know is it the fastest and smoothest card I own. I have 2 12.2 Samsung Pro Tablets and I purchased one for each device. Very fast, that's all I can say. The Samsung EVO is a good card also. I have those in our smart phones. Both cards or fast and reliable. There is also another Samsung PRO card that is black and has speeds up to 70 MB/s. DO NOT buy that one. I tried one, it failed, was sent another, it failed, and after the 3rd one failed, my money was returned.

Get Sandisk Micro SD Card HC Extreme. Regular cards has a lower writing speed

I'm getting just under 130MB/s read and write. It took under 2 hours to copy some files (around a TB) that took seven hours under USB 2.0.

The formatted capacity should be showing 29.6GB with exFAT. But I was able to measure 47MB/s read and 13MB/s write, in a USB 3.0 memory card reader. It is possible that your card reader is not UHS-1 capable.

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

Iam not sure about rewrite speeds of the card. I bought it for a HD Sony camcorder to use as a storage medium and it has worked very well. No problems. I recommend this product. Sorry can't directly answer your question, I am not so tech savvy.

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 can't remember the speed, but it is 8 gigs. 1 year later and no problems other then Windows 8 being a pos

I agree with what others have said. I own the Samsung PRO in the 16, 32, AND 64 GB sizes. The 16 GB size will have write speeds closer to the 50 MB/s because, like most flash products, the smaller sizes tend to have considerably lower write speeds than the larger sizes. (Read speeds are only slightly slower.) The 32 GB and 64 GB models give me write speeds in the 80-85 MB/s range. Amazon has not made this distinction very well, and it resulted in me initially buying the 16 GB size. So if you want the 80 MB/s write speeds, you will need either the 32 or 64 GB size.

rated speed for read/write. But Sandisk Class 4 tested among highest in lab tests.

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.

Read/Write speed, how fast you can transmit your files from/to the flash drive
