USB3.0 vs USB.2.0

[Updated Aug. 26 2013]

I had bought a new Seagate 2TB USB3.0 disk and gave it a spin. Here's some results that I wrote at the time; and some updates.

This was done on the Gigabyte FX990-UD7 mainboard which has an Eltron USB3.0 controller and I have it set up with two 250GB 3Gbit SATA2 disks on the Marvell RAID controller on the board, and an Intel 80 GB SSD disk.

USB2.0 is mostly limited to around 20-25MB second, depending on your controller. Remember, if you want network speeds over 10MB/sec you will have want to upgrade to a Gigabit home network. Then you can achieve speeds around 100 MB/sec.

So, it would be pretty clear that the days of 100 MBit networks are over. To accommodate these now ubiqous technologies as RAID, SSD and USB3, I expect gigabit switches to sell good the coming year.

Update:

Added one Kingston 120 GB SSD SATA3.0 drive.
From the USB3.0 to the new SATA3.0, I achieved around 310 MB per second accoring to the Resource Monitor, but the file dialog claimed substantially less.

One of the reasons I had to get the new SSD was ofcourse that the 3 year old 80 GB Intel drive was full, as it is the main system drive, so I have had no SSD to actually put stuff I use. The first thing I did was to move everything Java-related onto the new disk: JRE, JDK, Eclipse and the Android SDK. I noticed an immidiate 2x speedup, and before this, the software was located on the RAID0 drive in this test'

Also 'added' was a 4 GB ' AMD Radeon RAM disk'. This disk is used for Chrome and Windows temporary files. The disk is loaded very early in the boot sequence, and can probably host more interesting things.

Using a single test file of ~4 GB, except for when testing the 4 GB RAM disk, I used a 2.3 GB file.
These values are the observed max values under the Windows transfer dialog.

RAID0 2x3Gbit to USB3: 150MB/sec
USB to RAID0 2x3Gbit: 190MB/sec
SSD SATA2 to USB3: 180MB/sec
USB3 to SSD SATA2: 190MB/sec
SSD SATA2 to RAID0 2x3Gbit: 225MB/sec
RAID0 2x3Gbit to SSD SATA2: 135MB/sec

USB3 to SSD SATA3: 210MB/sec
SSD SATA3 to USB3: 215MB/sec

SSD SATA3 to SSD SATA 2: 266MB/sec

SSD SATA2 to SSD SATA 3: 180MB/sec

SSD SATA3 to RAMDISK: 506MB/sec <--- font="">

SSD SATA2 to RAMDISK: 220MB/sec

The Kingston SSD packaging claimed max 450 read speed, so caching probably caused those 506 :)

My new gaming rig!

CoolerMaster HAF 922 bigtower with built in glass panel side

2x 120mm fans on top. I managed to break a blade on the original 200x200x3 fan! Have a spare fan you want to donate?! :D

Specs:

• Gigabyte FXA990 UD7
• Intel 80GB SSD disk for system
• Samsung 160Gb SATA disk for data (I also moved all User directories to this drive to save space on the SSD. I can teach you how if you want!)
• 16 Gb 1600 Mhz RAM
• Phenom II X6 1100T CPU
• 2x Sapphire Radeon 6790 in Crossfire
• NXZT 5-fan controller
• Kingston dual fan RAM cooler
• Noctua SE CPU fan
• Gbit Ethernet with 9K Jumbo frames
• 24" BenQ HDMI LCD
• Manually BIOS-overclocked to 220 FSB. (So RAM goes as 1740 and CPU at 3.3Ghz I think.
• 2x 250GB Hitachi SATA 3.0Gbit in RAID0 on the Marvell ports
• 1x 320GB Hitachi SATA Deskstar 3.0Gbit
• 2x USB3 ports
• 7.1 Surround
• 6x USB2 ports with 2x power
• ESATA connector
• Corsair 750W V1 PSU

Front View

At the most, this monster draws about 500 Watts and seems to run smoothly.
One thing, the 6790 cards can be safely overclocked to 880 core speed, but do NOT mess with the Memory Speed clocks. That will get you BSODS. Also, I dont think it's completely stable on core speed 900Mhz.

A little note about the 6790 and CrossFire, it seems that you need to restart CrossFire before starting any games about half the time. Otherwise I get a flickering screen 50% of the time.

I am running Sapphire Trixx and enabled card syncing and disabled UPLS. That is supposed to do the trick. But not always it seems.

Also, if you happen to buy this motherboard and you have a Phenom II X4 960T, it will actually fit in the AM3 slot and works perfectly if your mobo has BIOS v7 or newer. (the 960T is the last of it's kind to do this. It has *both* DDR2 and DDR3 memory controllers.

I broke my 960T and had to get a new one, thats why I have a 1100T. But I fixed the broken pin on the 960T and put it back into it't proper AM2+ motherboard!

Super AMD Spider platform achieved!

AMD Spider Components:

• K9A2 Platinum
• Phenom II X4 960T factory core overclocked to of 3.4Ghz and all four cores run at 3 Ghz.
• 2x Sapphire Radeon 6770 in CrossFire
• 4x1 GB Kingston HyperX PC8500 gives me 1066 DRAM speed too!
  
  
• 1x Intel 320 SSD at 80 GB
• 2x Samsung 160GB in SATA/Windows striped RAID 0
• 2x Maxtor 320GB in SATA RAID on independent PCI controller!
• 1x Corsair TX 750 Watt
• 1x Noctua  double fanned coppercoil hybrid cooler fan

Sapphire cards are somewhat unstable at overclocking, even factory overclocked ones.   None of the 10-12 temperature sensors stays between 25 and 50!

I did a FULL overclock of both CPU and GPU (max settings CPU at 3600, GPU at 900 etc but I got artifacts in Crysis! Going to slowly overclock bit by bit until i have a stable rig!

Oh yeah did i mention i paid under $2000 (10000 NOK) for this self build project!
