Hello
again guys, hello performance lovers and welcome to this new "All in one
Review", on this post I want to share with you some valuable
information comparing the all new USB 3.0 standard Vs the previous
generation USB 2.0 in term of performance, of course the new USB 3.0 is
faster but do you have any idea how much its faster ?
Lets have a small briefing, features and specifications about the new generation of USB, Then some selection of best reviewers.
On
September 18, 2007, Pat Gelsinger demonstrated USB 3.0 at the Intel
Developer Forum. The USB 3.0 Promoter Group announced on November 17,
2008, that version 3.0 of the specification had been completed and was
transitioned to the USB Implementers Forum (USB-IF), the managing body
of USB specifications. This move effectively opened the spec to hardware
developers for implementation in future products. The first USB 3.0
ports were featured on the Asus P6X58 motherboard; however this board
was canceled before production.
Why USB 3.0 is only around 150MB/s speed:
Because of the CRC check on the two ends, the final performance result of the USB 3.0 is not as we expect, take look at the Theoretical table bellow:

Features:
* A new major feature is the SuperSpeed
bus, which provides a fourth transfer mode at 4.8 Gbit/s. The raw
throughput is 4 Gbit/s, and the specification considers it reasonable to
achieve 3.2 Gbit/s (0.4 GByte/s or 400 MByte/s) or more after protocol
overhead.

USB 3.0 vs USB 2.0 Super Talent Benchmarks Test :
MacBook USB performance:
On the new Retina MacBook pro USB 3.0Vs the old 2011 MacBook pro USB2.0, performance diference is huge (by anandtech).
USB 2.0 Vs USB 3.0 ATTO Benchmark result :
Using ASUS TUF X58 SABERTOOTH motherboard and 7,200 RPM internal drive, (by bjorn3d)
Why USB 3.0 is only around 150MB/s speed:
Because of the CRC check on the two ends, the final performance result of the USB 3.0 is not as we expect, take look at the Theoretical table bellow:
| Interface | Data Rate (Bits/s) | Theoretical Bandwidth (Bytes/s) | Theoretical Bandwidth After 8b/10b Encoding (Bytes/s) |
|---|---|---|---|
| USB 2.0 | 480Mb/s | 60MB/s | 48MB/s |
| USB 3.0 | 5Gb/s | 625MB/s | 500MB/s |

ReplyDeleteI don't know why bloggers jealous from other bloggers if they are getting success Like GuruHt.com :D
ReplyDeleteif you want me to put your linkback to your site i will do this for you but not for reporting lolx :D
