California-based Lexar on Tuesday introduced its High-Performance microSDHC UHS-I and microSDXC UHS-I memory cards for smartphones, tablets, and sports camcorders. These cards carry a Class 10 speed classification, and deliver read transfer speeds up to 300x, or rather, a speedy 45 MB per second. Lexar said the cards are design for "adventure seekers" and "adrenaline junkies".

"These cards enable outdoor enthusiasts to capture up to eight hours of their greatest moments in HD and share it with friends faster," the company said. "Users can also store up to 24,800 photos or 14,200 songs, and when paired with the included USB 3.0 reader, get fast transfer rates from their memory card to their PC or Mac computer."

As indicated, both cards come with a USB 3.0 reader that enables users to quickly play back and transfer their favorite media files. The microSDHC UHS-I card comes in a 32 GB capacity whereas the microSDXC UHS-I offers 64 GB of storage space. Both come with a limited lifetime warranty, and the USB 3.0 reader has its own one-year limited warranty.

Wes Brewer, vice president, products and technology for Lexar, said that the design of Lexar's new 64 GB microSDXC card was made possible by utilizing Micron’s newest, 64-Gbit, 20-nm process technology NAND flash memory.

"Together with creative die-stacking techniques and uniquely engineered firmware in our UHS-I capable controller, Lexar was able to design and produce this product at the 300x performance level to meet the needs of our customers," he said. "Our total High-Performance retail solution – which includes an ultra-compact USB 3.0 microSD high-speed reader – achieves an optimal blend of price and performance demanded by our retail customers that focus on video capture and quick file offloading to a PC and the Internet."

In its announcement on Tuesday, Lexar said that it works with major mobile device manufacturers to ensure that its cards are compatible with their devices. Lexar's memory designs also undergo extensive testing in the Lexar Quality Labs to ensure performance, quality, compatibility, and reliability with more than 800 digital devices.

Lexar High-Performance microSDHC UHS-I and microSDXC UHS-I memory cards will be available for purchase in November for $69.99 (32 GB) and $139.99 (64 GB) from Lexar.com and leading e-tail outlets worldwide.

    nobody cares about the write speeds? .. which have conveniently not been advertised!

    Let's hope that phones or tablets can work at that speed

    60-80% of the read speeds I'm guessing. Maybe 30-35MBps on the lower conservative end. Funny they don't mention it though since the write speed is what really limits how fast you can take pictures or record video as you wait for your device to empty it's buffer.

    why put something like that on usb 3.o ? usb 2.o is good enough .. marketing i suppose.

    USB2 is limited to around 30MB/s realistic so it would be a bottleneck in some situations.

    "14,200 songs"...

    Even at $0.99 per song this is clearly promoting illegal downloads. Let's notify the RIAA :-)

    You are joking, right ?

    Yes they never seem to post write speeds in these ads thinly disguised as articles! It is almost if no one ever needs to write to these devices, they are magical devices just read from them and get the exact information you are looking for!

    Based on what? Low speed cards? There's no way to know until they release more specs, however existing high-speed microSDHC/XC cards tend to have lower write speeds as a percentage of their read speeds.

    For high-speed cards, I've seen a bunch of SDHC/SDXC UHS memory cards with read speeds of 30-40MB/sec. For those same cards, I've seen write speeds as low as 25% of the read speed. Most are in the 33-45% range.

    My guess of write speeds of 60-80% of the read speed was based on previous experience.
    I obsessively run HDTune and h2bench on every flash drive, sd card, ssd and hard drive that comes into my shop. I have read and write test results for over 300 diffrent devices and nearly 100 just from MicroSD and SD cards.

    Having said that, most of the memory cards I test are customer equipment, meaning they're usually the cheapest available cards since they don't care or know about the varying performance differences between higher end SD cards.

    I was going to argue with your claim about how much slower write speeds are on the newest sd memory but after doing some research, you're right. In fact, higher performance NAND-flash memory has write speeds less than 20% of the stated read speeds.

    In a technology overview directly from Toshiba, they compare different types of NAND flash memory and NOR memory. In general:

    SLC NAND Chips have read rates about 3x their write speeds
    MLC NAND Chips have read rates 7-9x faster than write speeds (and support much higher capacities)
    MLC NOR Chips can read at rates of 150-200x faster than their write speeds. The read speeds aren't amazingly fast, their write speeds just suck terribly. This is why NOR-flash is rarely used for storage applications but works well for booting from flash or executing code directly from the flash memory. Think of your cell phone booting etc.
