I tested the Kingston 8GB class 10 micro SD card using ATTO Disk BenchMark v2.46
Write speed was approximately 7.5 MB/sec, Read speed was approximately 12 MB/sec.
I requested an RMA from Kingston and returned it for an exchange. The new one measured:
Write speed approximately 7 MB/sec, Read speed approximately 13 MB/sec.
Compare these to a Kingston 8GB micro SD class 4 from 2 years ago, which measured:
Write speed approximately 9 MB/sec, Read speed approximately 16 MB/sec.
Or an ADATA 8GB micro SD class 6 (FWIW 1st one of these had to be exchanged too):
Write speed approximately 7 MB/sec, Read speed approximately 16 MB/sec.
Conclusion, unless an application only needs to read quickly, where cameras for instance need to write quickly, I would not buy this SD card again for class 10 performance, since I can get the same result with cheaper claas cards, or better performance with another brand. I also tested each card in my Nikon DSLR, results tracked the Benchmark testing, measured as number of pictures in a 20 second period with the shutter button held down.
Update:
I recently bought a Wintec 16GB class 10, same measurement setup indicated 12 MB/sec write, 16 MB/sec read speed. Besides the wintec actually doing what it was advertised to, these results indicate nothing in my hardware was keeping the Kingston card from achieving 10 MB/sec if it had been good enough.

SD cards have a universal standard they have to meet to get a class rating. The class number guarantees a minimum write speed. MINIMUM being the point, it is NOT an average.
This card is highly rated by numerous computer hardware websites that benchmark flash card memory. On all of those sites the benchmarks show this card exceeding it's rated write speed of 10MB/s (most by double the rated speed).
This particular card is rated as a class 10 and therefore have a minimum of 10MB a sec. After using 5 different benchmark programs on 2 computers and an Android phone my results were: Writing speed: 6-8.6 MByte/s, Reading speed: 15-18.2 MByte/s.
At this point I still trust the Kingston name so I have opted for an exchange.
UPDATE: Got the replacement, tested with the same 5 programs and pretty much got the same result (ever so slightly higher average). So I am returning it and going to try another brand (keep reading).
On a side note. I decided to test my Lexar Professional Series 8 GB 133x Class 6 SDHC Flash Memory Card SD8GB-133-381 that I bought here on Amazon back in Mar09. That class 6 card, with the same benchmark programs were: Writing speed: 16-17.8 MB/s, Reading speed: 19-21.2 MB/s.

I bought the card and it worked fine for about 3 months than completely failed. Since it has a "Lifetime Warranty", I took advantage of that, returned it to Kingston, and since have had to follow up every step of the return process.
I got delivery confirmation from the Postal Service, then had to send Kingston an e mail two days after the card was delivered to find out what the status was on the order. Their website said they'd be a little more speedy on processing warranty claims. Two days later I got a note that they'd get the mailroom to move the package through, which they seem to have done, although it should have already moved through based on what their website says. I waited a day for an update on their website as to the status of the return and checked it this morning.
They finally processed the return, but DARN THE LUCK, the replacement item is BACKORDERED. I called customer service, and the lady was very nice, but told me the item "Just went on backorder" so she had no idea as to when it would be coming in and would have to check with their engineers to find out. Engineers? She didn't offer a replacement product or any other solution other than to wait to hear back from the engineers.
The card was OK, but when it failed I lost everything on it. Now I'm waiting longer than I should have to for a replacement. What good is a warranty if you can't replace a defective product? I'm not a happy man.
