USB 3.0 drive to be available early next month

Super Talent Technology has been making a name for itself in the Solid State Drive market with speedy SSDs and its PCIe based RAIDDrive solutions. The company is now announcing that it plans to be the first in the world to ship USB 3.0 flash drives, with first availability at the beginning of December.
The SuperSpeed USB 3.0 interface supports transfer speeds up to ten times faster than regular USB 2.0. Although it has a theoretical throughput of 5 Gbps, USB 3.0 still uses 8b10 encoding. That overhead means that real world applications will top out at around 400 MB/s, still much faster than the typical 35-40 MB/s with USB 2.0.

"This product underscores Super Talent’s continued leadership in USB drives.” said Super Talent's COO, Mr. C.H. Lee. “We’ve developed the world’s first mobile USB 3.0 flash drive. It delivers phenomenal performance and it incorporates our own patented technology”.

Super Talent's new RAIDDrive USB 3.0 series uses patented “multiple pairs of differential serial data lines technology” for optimal NAND flash performance. It will transfer data at 200 MB/s using a USB 3.0 port,  but it can reach up to 320MB/s using a UAS Protocol driver.

The USB Attached SCSI (UAS) protocol runs over the USB 3.0 interface. The specifications were developed by the USB-IF to enhance the efficiency of USB storage devices. This is supposed to result in higher speeds and more consistent performance, as well as lower CPU utilization for both Hi-Speed USB 2.0 and SuperSpeed USB 3.0 devices.

The new drive uses USB 3.0 hardware from NEC, and will be available in 32GB, 64GB and 128GB capacities. It will be fully backward compatible with all USB ports, but operates at much slower speeds. It measures a 95 x 37 x13 mm, and comes with a limited lifetime warranty. Super Talent states that the new drive will have more than 10 years of data retention.

"SuperSpeed allows USB to meet the transfer demands of modern mass storage devices," said Yoshiyuki Yamada, Senior Engineering Manager, Custom SOC Solutions Strategic Business Unit, at NEC Electronics America, Inc.

The new drive comes at a good time, as the first motherboards supporting USB 3.0 have just hit the market. Pricing information is not yet available.

"SuperSpeed" is NOT 4.8 Gbps

"SuperSpeed" is 5.0 Gbps, NOT 4.8 Gbps (and as a result your 8b/10b math yields incorrect numbers). Read the specification at last.

What is 8b/10b encoding?

What if you dont want your data encoded?

8b/10b encoding is required to send data serially. In serial communications, it takes 10bits to send 8bits of data with the first and the last being used to synchronize each packet with the transmitter/receiver.

8b/10b is used for error detection (frequency is quite high and cabling is not ideal), not for synchronization. RTFM.

You are also mixing up bytes with packets.

It's not actually used for error detection. 8b/10b is a form of line coding and is used to achieve DC-balance and bounded disparity

Even if you use 8b/10b for DC-balance and bounded disparity though, you get some amount of free error detection, because only a small (25%, by definition) subset of 10b codes have 8b counterparts. If you get an invalid 10b code, you know there was an error in the transmission of that byte.

I think I read last year it was 4.8Gbps, and now it change to 5? So either rounding or they increased the speed.
