• Wireless AC slow (and different) read/write speeds

  Hi all

  I just bought a new Mac Mini and unfortunately it is too far from my media server to run an ethernet cable (I just moved) so I use an Airport Extreme (new model with AC Protocol).  But the read speeds seem to be slow I can't broadcast some movies from high on the server bandwidth.  I tested the speed of transfer, and it seems that I get the following:

  READ: 24 MB/s (or 192 MB/s)

  WRITE: 8 MB/s (or 64 Mb/s)

  Can someone explain to me why these speeds are not the same?  And should not be a lot faster?  I get full signal and I joined technical details if this helps to explain anything. I would like to know what speeds you guys get with your Airport Extreme.

  Thank you!

  

  How far is your Mac to your server?

  There the walls or something in the line of fire?

  Have you tried the 2.4 GHz connection instead?

• SSD Ultra II read & write speed problem

  Hello world

  I'm hoping to get help please about an SSD, I just bought and do not seem to be getting anywhere near the advertised speed it is supposed to be able, I only spent by technical support yet as thought someone here might know the answer.

  I bought the Ultra II capable of up to 550 MB/s write in reading and 500 MB/s, but after doing some 480 GB testing the 3rd party software and the State of SanDisk my speed to read dashboard is about 346 MB/s and writing is about 236 MB / s, is not anywhere near the announced speeds.

  I made sure the drivers are up to date in the dashboard, checked my motherboard and confirmed he has 2 SATA2 and SATA3 2 ports, bought new cables SATA 6.0 GB of data and made sure that they are plugged on SATA3 ports using the manual of the motherboard, but I get still only these slow speeds.

  Any help anyone can offer would be great, thanks.

  What is the MB brand and model? Some MB have several SATA 6 GB ports on different controllers. Intel SATA chipsets tend to perform best. I have a MB with Intel and AS Media SATA 3 chipsets and I see the same performance you see if I connect an SSD SATA 3 ports that use the controller AS Media.

• ProBook G3 450: Time assets 100% Intermittent drive with 0 kB/s read/write speed

  Hello

  I am facing an active time for intermittent drive 100% with 0 kB/s reading or writing speed with my G3 450 ProBook running on 10 to win.

  Meanwhile, the laptop does not. This effect always lasts exactly 60 s (visible in the Task Manager), and after that, the hard drive still responds once. Looks like some kind of timeout that happens after 60 seconds before returning to normal behavior. Sometimes the 100% active time occurs every few minutes and sometimes I can work for hours without interruption. So far I was not able to trigger the effect.

  A Google search on "100% active time" returns a lot of suggestions like disable the superfetch, windows search, and the background intelligent transfer service. None of this solves the problem. The hard disk drivers (Toshiba) and the (Intel) SATA controller are up to date. I already reinstalled Win 10 who do not help either.

  I have another problem with this ProBook. I don't think that this is related to this problem. However, you never know...:

  http://h30434.www3.HP.com/T5/business-notebooks/intermittent-loss-of-WiFi-connection/m-p/5582927#M13...

  I'm out of ideas. Any input is highly appreciated.

  Thank you

  Martin

  Well, in the meantime, I found a solution... I bought a new HARD disk that is supported to win 10. It's a little embarrassing that HP sells the laptop with Win 10 and it does not work as it should. But anyway: problem solved.

• Sony ILÇE-7R - what is the speed of read/write in the camera

  I have several Sony ILÇE-7R cameras used for a given application where more than 80 panes in a row with 1 second interval occur.

  When you are taking pictures on a 1 sec shutter time / 1.2 s, then the camera tends to slow when writing the buffer on the SD card. (A suitable high-speed sdcard has been used).  When the buffer is disabled on the SD card, then the camera accepts no any command of the shutter (IR Led or cable gives the same question), so I'm missing components/images.

  What is the read/write speed in the camera?

  What are the compensation of buffer time?

  Are there settings that can improve the buffer time on the SD card, while taking still pictures of compensation?

  Is there firmware settings that have been implemented to improve the write speed camera?

  Thank you very much

  Kind regards

  
  

• How do you know the speed of read/write of a flash drive?

  Who knows a program to read/write speed?

  Hi Cristi,

  Thanks for posting in the Microsoft Community.

  An indication of the standard flash drives read/write speeds is the following:

  USB 2.0:

  Sequential write speed range = 4-10 MB/S

  Sequential read speed range = 15 to 25 MB/S

  USB 3.0:

  Sequential write speed range = upto20 MB/S

  Sequential read speed range = upto45 MB/S

  These reading and writing speeds offer a guide to the read/write Flash Drive performance and have been identified in recent tests. Please note that we are changing the components USB Flash Drive at any time based on the availability and cost. This means that the read/write speeds above cannot be guaranteed.

  You can use your favorite search engine to search for this application that measures the speed of read/write of flash drives.

  Warning: Using third-party software, including hardware drivers can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the use of third-party software can be solved. Software using third party is at your own risk.

• a speed of read/write DAQ card mode change will reach 200K

  HEY, man,

  I have a project needs to test two points I name them point A and point B, the first time, I should point A 5V DC input, voltage inductive test point B, sencodly, give point B 5V DC input and inductive point test output voltage, this means and two analog ports must read and write sharing mode , and the test speed must be 100 KB, if I have a 200 KB data acquisition card, can the speed of read/write mode change reach 100 KB for an analog port? or, please give your suggest for my this kind of situation, thank you.

  Hi API,.

  I see that you are trying to measure voltages using a single channel at a time on a data acquisition card.

  Unfortunately, you cannot change the inputs to the outputs or vice versa on a map of data acquisition, they are static.

  What I recommend is either using a switch like this: http://sine.ni.com/nips/cds/view/p/lang/en/nid/207130 where you will need a high chassis.

  Or, having four channels, 2 inputs and 2 outputs and try to measure it. You should have the necessary speed as well.

  If you have any other questions, I'd be happy to answer.

  Thank you very much

• SSD on MPB early 2011 (13 inches) slow write speed

  Hey all,.

  I installed an SSD Crucial of MX300 in my MPB 2011 (13 inches). I get that I have probably will not hit the read/write 510/510, said the player, but right now I get only a writing speed of 240 vs a reading of 470.

  Any ideas on why it's so slow?

  Thank you.

  What is it connected to internally? If we replace the optical drive, then it may be because it's a 3 Gb/s bus rather than the primary drive SATA 6 GB/s bus connects to.

  Do you have your repartition and reformat the SSD drive before using it? It is not unusual to see some write speeds slower than reading speeds. The MX300 is a new economic model that may be slower than expected in real use.

• Tecra A8 DVD don't read/write DVD-R 1-16 x.

  Using Sonic Record DLA, Tecra A8 DVD don't read/write DVD-R 1-16 x. Ok work on DVD - R 1-8 x and CD DVD - R 1-16 x has tested successfully on the two recent Toshiba Satellite Pro and HP Office. Have updated the Bios, software DVD-RAM and Sonic DLA.

  Hey,.

  What exactly do you mean? This means that you can t burn DVD-r with 16 x speed?
  In this case, you should check the specifications of your CD/DVD drive. Not all models support this speed of combustion. In addition, I recommend using 8 x only, he speed will give you a better quality of the burned data/average.

  You must also use different types of media. I believe that your other computers have different drives in order to test different mediums. I have a good experience with Verbatim DVD-R.

• A6000 SD card write speed?

  What is the write speed maximum of internal A6000s... one of my friends offered to buy my current card at almost full prices. But there is no reason to upgrade if im already at maximum speed cameras (an example would be the Canon 5 d M3, which cannot write to SD card with about 45 MB/S)

  So, what is the write speed from MAX SDcard of the Sony (Ilçe-6000) a6000? is it not able to take advantage of a 280 MB/s of sandisk card?

  You can not buy a SD card that will not work in an A6000. If the card you get is capable of speeds of reading/writing that cannot the A6000, the A6000 can still use the card, and your next camera may be able to take advantage of the extra speed.

  In other words, which are always slower, either the camera or the card, which will be the limiting factor, which is ok, and if the card can run faster than the camera can manage, they still work together. And if the device can run faster than the card, the camera will slow down until no matter what the speed, the card can handle.

  Then buy the fastest card you can get and if your A6000 cannot take advantage of the extra speed, he can still use it, and maybe your A6000M2 will be able to use the extra speed.

• F20-136: CD write speed is 24 x while it should be 52 x

  I recently bought a F20-136... the CD write speed is 24 x while it should be 52 x... can someone tell me where I could get the latest driver/firmware for my drive from DVD-RAM (Mat * a DVD - RAM UJ-years 840).

  Thank you

  Hello

  I n know where you found the information on the 52 x write speed of CD, but I checked the disc and found this properties:
  Maximum speed:
  Read
  CD-ROM 24 x
  DVD - ROM 8 x
  To write
  CD - R 24 x
  CD - RW 4 x
  HS CD - RW 10 x
  US CD - RW 10 x
  US + CD - RW-
  DVD - R 8 x
  DVD - RW 4 x
  DVD + R 8 x
  DVD + R (Double Layer) 2.4 x
  DVD + RW 4 x
  DVD - RAM 5 x

  As you can see the drive can write CD - R and 24 x CD.

• A better way to make a continuous read/write on a NOR-6008

  Hello

  I use a USB of NOR-6008 module and have a loop of the software configuration where I acquire analog signals, digital signals, then, then put a digital high or low and repeat. I use digital multiplex outside the material so that I can use 6 of the analog inputs to read 12 signals. The digital inputs that I have are connected to the buttons on a panel that are used for the entry instead of the screen of the computer of the user. My loop is also to build a buffer zone of all the signals on the analog and digital lines that I read in so I can on average and this process elsewhere in the program.

  The question that I am running is because this loop is very slow and on the final product is performed on a touch screen, XP Embedded PC and just this acquisition loop begins again as much CPU as the rest of my program. I would say that drops of loops on 4 or 5 cycles per second, which means that my update of 2 multiplex signals or longer than a second time. I would really like to better performance and does not use as much of my CPU resources.

  I use a way simple enough to make the loop of the acquisition, by setting the parameters I, reading, deleting the task, defining the parameters DI, read, erase the task and then by setting the parameters, write about it and delete the task, which gives a slight delay and repeat.

  Any thoughts on a better way to start the read/write that what I'm doing?

  I have attached the code examples in the loop of the acquisition that I use.

  Thank you!

  First of all, the best plan is to move the chain DAQmx before the loop to create and use a start DAQmx, then write in the loop, then clear once the loop ends.  This configuration must be done once, not every time you write the channel.  This should speed things up considerably.

• Help? the source volume is read-write and can not be disassembled...

  I use 10.11.5 on an iMac 21.5 ", end of 2009 and I want to restore the OS X 10.11.5 to HD on an external drive but I get this message" Source volume is read = write and cannot be disassembled, so it cannot be copied from block. "  I can find answers do not address El Capitan.  Help would be greatly appreciated.

  .. .Goldie

  You use disk utility's restore feature?

  If the HD has a recovery partition, you can make starting in place of the recovery.

  Or you can use SuperDuper! (the basic version is free and can copy the entire disk, the paid version allows "smart updates", which copies only files that are different, saving time) running on externally to perform the copy.

• DVD recorder is not read/write discs DVD-RAM on Satellite A200-1GH

  Hello!!

  I have the problem as the topic - my DVD drive is not read/write DVD-RAM discs (recorder: HL-DT-ST DVDRAM GSA-T20N). Unfortunately, there is no any drivers (more recent than I've got) for this recorder on the Toshiba, not even site on LG or Microsoft. What should I do?

  Greetings

  Hello

  To be honest, it's quite strange. If the laptop is preinstalled with recovery image, it should work. I tested it on my laptop 5 minutes ago and it works. The DVD-RAM disc is readable and different documents can be saved on the disk too.

  Do you use your own installation of OS, or you still have some factory settings?
