Depending on how you implement it, speeds can be quite fast with a raw speed of 12.5 Mbps and using line coding techniques can go to around 33 Mbps.

It is also backward compatible with I2C target devices. Other devices can be targets or secondary controllers. It does use the usual two wires, SCL for the clock and SDA for data. I3C, created by the MIPI Alliance, aims to fix these problems. Besides that, there is poor support for adding and removing devices dynamically or discovering devices automatically. I2C can be relatively slow and SPI usually requires extra pins for each device. I2C and SPI are mature but they do have problems. But now there is I3C, a relatively new industry standard that is getting a bit of traction. Talking between chips these days tends to use I2C or SPI or some variation of these to send and receive data over a handful of pins. We’ve seen the same thing in embedded devices.

They seem to be somewhat related.Remember old hard drives with their giant ribbon cables? They went serial and now the power cables are way thicker than the data cables. Once the disk queue length dropped down to 1-2, the system was manageable again.ĭon't know if that problem will repeat with the new drive at some point, but I would care not to take chances and just get the board replaced at this point. That behavior would go on for the first 15 minutes of boot, and perfmon showed a long disk queue length during that fifteen minutes. Also, VAIO Gate, one of the programs built in that loads on startup, would cause my mouse to hang, not move for a couple seconds, and then start to move from where it should have been based on the motion I used to move it.

The system was slow: Mouse clicks did not respond immediately and sometimes took anywhere from 2-10 seconds to register, directory listings were slow to load, browser windows were the worst and just scrolling up and down a page could take 5-10 seconds for the scroll bar to even move, and when the scroll bar on the browser did move, it was often jerky. With the previous two drives, the behavior was erratic, but it was repeatable on nearly every boot. This one has been fine for over a month now.

The second drive started failing after four or five days of use. Both drives were fine when I initially used them, and the first drive started failing after months of use. In my case with the previous two drives, the hard disk drive controller seemed to be magnafoozled on both.

NEC Electronics USB 3.0 Host Controller Driver (previous BSOD issues with 2010 version) No updates are available through Sony, and I am having a difficult time finding them through Renesas Support. I believe this is a driver issue related to the blue screens that occur with the driver version installed on my system. I have a SanDisk 16 GB USB 2.0 drive that works fine. I do not have this problem if I use the one and only USB 2.0 port on the system. If I try to move files off my system onto the flash drive and then also try to move/copy files within the flash drive to a different folder, the drive disappears from the system and I get a message that the destination path does not exist anymore. Ever since I bought this system, I have had issues with an older Kingston 8 GB USB 2.0 flash drive.
