• 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.

• 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

  
  

• Maximum speed of read/write taken supported Sony Xperia Z2 for MicroSD cards

  I am looking to buy a microSD for my Xperia Z2 phone (6503). My question is: how fast it can write data to an SD card. For all I know, these speeds are dependent on the controller of the SD card. If I'll know it approximate numbers I can acquire an adequate microSD card. Right now I'm trying to decide between: SanDisk SDSDQX - 064 G-U46A Extreme Plus 64 GB - 80 MB / s GB SanDisk SDSDQUA - 128 G-G46A 128 Ultra - 30 MB/s write for these microSD cards speeds half accelerated indicated reed are numbers. I like 128 GB Ultra card capacity, but would not hesitate to buy faster 64 GB card of more extreme.

  If you use 4K as recording features, you may need to get a high speed SD! (go to the Maximum speed you can)

  So I think that like extreme would be preferable in this case, but if your phone is what use you (like me) the maximum capacity (which has better speed as well, if not useless) I use a class 10 128 Go!

  Like many, I know, I think that same 30 MBP will be sufficient for a 4K video!

• increase speed visa read write

  Hi guys,.

  I use the visa read and write the example, but I am facing a problem when using it in a software expansion, and I can receive only date when the vi has been slown down (using the bulb).

  The program really works on her own with the defined settings.

  So, do you have any ideas/suggestions on how to significantly increase the speed of this vi (joint)? In addition, it seems to create a problem with the playback of data

  Thank you very much

  Roll bytes to the port and the delay.

  Rely on the chariot of the termination

  Use a number larger than the bytes expected.

• 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.

• I have a memory card reader/writer. You want to know what it takes to put photos on card

  I have a video photo frame that I put my memory card in to see photos. but cannot modify them. so I bought a card reader/writer, I have used before and had no problem. but didn't write what I did. now, I don't know how to recover my pictures on the computer to the memory card.

  If you insert the memory card into the reader and go to...
  Start / computer... you will find one or more removable
  Discs that represent the slots in the card reader.

  For example...

  Removable disk (e :))
  Removable drive (g)
  Removable disk (h :))

  Once you learn which represents removable disk
  the card slot is in you can copy and paste or drag and drop
  photos on the drive letter that you want to copy on the map. If
  you get to pictures in your folder images, you can
  Right-click on a group of photos or a folder and the
  menu choose... Send to / removable disk (? :))...)

  Tip: There is a limited number of files can be copied
  in the memory card root directory. You can see a
  error, something like:

  "Impossible to copy the XXXX: failed to create the directory or file.

  You can avoid this problem by placing the files in folders
  on the map.

• Cannot access the card reader/writer internal Flash

  After a few updates, I can access is no longer any SD card inserted into the card reader/writer Flash. I tried to use the convenience store but just that said there is no problem found. When I insert the SD card, it appears in the 'control Panel\Hardware and Sound\Devices and printers' as ' Flash Card Reader/Writer "but I am not able to access the card.

  Hi Tim,.

  Was there a card player offered to you via Windows update driver update?

  -You see no drive letter assigned to the flash card while you see for readers in the window 'computer '?

  -What is the error you get when you go to the map?

  I suggest you try to change the drive letter assigned to the card and see if that helps.

  1 type diskmgmt.msc in the RUN prompt or in start search to open the computer management window.

  2. right click on the indicated card device and select "paths of access and change drive letter.

  3. click on change if there is an assigned drive letter, and then change to another letter. If this is not the case, click on add and select a drive letter.

  4 restart the computer so that the changes are applied and see if you are able to access the content in the map.

  For more information: http://windows.microsoft.com/en-in/windows7/change-add-or-remove-a-drive-letter

  Alternatively, you can try to uninstall and reinstall the drivers for the card and see if that makes a difference.

  Visit the website of your computer manufacturer to download and install the latest drivers.

  Let us know the results.

• Open physical standby mode read/write to test without return of flame

  I have successfully installed a physical database standby 10 gr 2 (10.2.0.3 EA). Now I have to test my application with the database pending, so I have to
  Open (enable) in read/write mode (don't want to use FLASHBACK DATABASE), I know that I have to recreate the database pending scracth after completing the test.
  
  So far, I did these steps:
  
  1. on the PRIMARY database, I disabled the log destination archive:
  ALTER system set log_archive_dest_state_2 = 'reporter ';
  2. on the day before, I cancel managed recovery
  ALTER database recover managed standby database cancel;
  
  
  Can anyone provide the remaining steps to open the write standby database? I searched the oracle documentation and all the steps require the flashbak database.
  
  Thanks in advance.
  
  S.H.

  Ok

  You could do a failover on the eve (without doing anything at the elementary level)

  So to run these on your watch.

  SQL > alter database recover managed standby database cancel;
  Database altered.
  SQL > alter database recover managed standby database finish;
  Database altered.
  SQL > alter database validation at the transition to the primary with the stop of the session;
  Database altered.
  SQL > alter database open;
  Database altered.

  Then simply stop the day before (not primary) and rebuild as the standby again. Delete and re-create.

  Make sure that your Data Guard alter system set log_archive_dest_state_2 = delay; Are fixed on both sides.

  This can help:

  http://www.Oracle.com/technetwork/database/features/availability/MAA-WP-10gR2-faststartfailoverbestp-131997.PDF

  You want to split the day before with really nothing do in elementary school except reporter.

• How to open a physical standby database "Manual" in read/write mode

  Hello
  
  I am running Oracle Database 10g Release 10.2.0.3.0 - 64 bit Standard Edition Production on Linux version 2.6.9 - 42.0.8.ELsmp ([email protected]) (version gcc 3.4.6 20060404 (Red Hat 3.4.6 - 3))
  
  I created a physical standby database, but since I am running Standard Edition, I don't use the features in DataGuard. I use the utility rsync to copy on the data pending archivelogs, and I periodically applied to the standby database.
  
  The standby database is started in this way:
  
  startup nomount pfile='/u01/oradata/orcl/initorcl.stdby';
  ALTER database base_de_donnees eve of Mount;
  
  Everything works perfectly, I can "open database in read-only alter" and then I can make selects in the tables to confirm that everything is up-to-date.
  
  The thing is, if I stop the database and then perform the boot simply:
  
  stop immediately;
  start-up;
  
  The database opens with an error message, but it is always in read-only mode...
  
  I read that the default behavior for a database ensure must open read-only, as I am experiencing, but I would like to know what is the right way to open it in read-write mode correctly (I understand that after this, my watch will not standby more and I need to recreate my database pending).
  
  Thank you

  Try: -.

  ALTER database activate standby database;

  This should open read-write (you will not be able to recover thereafter)

• Data acquisition in LabView for other suppliers DAQ cards that NEITHER

  Hello

  I am a beginner in LabView programming. I have a 32 channels base PCI card DAQ (i.e. PCI-1602 of the manufacturer, ICPDAS) and I want it to interface with Labview 8.5.

  So how cards DAQ in Labview 8.5, which are manufactured by other suppliers that NEITHER? Should I DAQmx (or some other driver) for that?

  What are the other drivers/components required to access of data PCI-1602 (device) of LabView 8.5 acquisition card?

  (1602-PCI card driver are installed in my win XP and dispalyed in Device Manager).

  Please provide some tutorial above mentioned the problem to interface.

  Please guide me in this regard. Thank you

  Please guide me in this regard. Thank you

  According to what you do with the DAQ cards, they can do the job however, from experience, there are some functions that I could achieve with the cards NOR that I couldn't with 3rd-party maufacturers.  This does not mean that this is your case. However, it is worth noting that it took me a while to understand why the code has worked with a single data acquisition card (NOR) but not another (Non-OR).

  The drivers that you have installed may or may not include examples and code in VI.  They may be DLL.  If this is the case, you can write LabVIEW "Wrappers" around these functions, as it will simplify your life.  If the drivers are in the form of DLLs, and there are no examples of LabvIEW or available VI, you must read on node library function call.

• Read/write port DAQmx questions

  Environment

  Windows XP SP3

  LabView 7.1

  NOR-DAQmx 8.7.1

  (2) PCI-DIO-96 cards

  I'm trying to move from the level of registry TDAQ programming DAQmx and give me an "intensive" in mx.  I'm not sure about a few things.

  I need to put in place 20 channels/tasks that will run a mix of single, large port (8-bit) bed and written.  Some will be handshaking (82 c 55 mode 1) and some no handshake (82 c 55 mode 0).

  The plan is to create all tasks during an initialization routine and save the names of global tasks.  I open the task after creation and use the globals during the main part of the program execution, when I make the reads/writes on the port.  The body can run for hours at a time.  When the main is closed, the stop routiine close all tasks to exit ahead.

  Regarding the task creation/destruction - is it safe to create tasks and leave them open, or should they be created and destroyed every time that a write is performed?

  Regarding the port reads/writes, I suppose that when a port single read/write is made, there is no established buffer.  Is this correct?  Specifically, if I use the method above and leave task open, is it possible saturation of buffer or something similar to happen?

  TIA

  Charlie

  Regret - Yes, you said 7.1 - I can't keep back away, but here is a screenshot

  

  And - the task is saved outside of LabVIEW, so it's not really 'Open' or 'Closed', even when programmatically, create and destroy jobs.  Tasks exist or do not exist.  If they exist and have no errors, they can be run.

  Tampons are to move data to and from the device.  For static DIO, this isn't a problem.  You CAN run into problems with a task of acquiring buttons if it acquires data as soon as you read the data, but you can work around this by starting and stopping the task properly.

• Connect an SSI absolute encoder to a DAQ card

  Hello, everyone

  I try to connect four encoders of DAQ cards. Two of them are in quadrature encoders and the rest two absolute encoders. I'm guessing that connects the two quadrature encoders to both timers/counters on the card. But what of the SSI absolute encoders? Anyone can give a clue? Thank you very much.

  Either way, I am using PCI-6251 and xPC Target.

  Pengfei

  Hi Pengfei,

  If you do not use our driver so I don't know if this is supported, but here's how I would do it using DAQmx...

  According to the features of calendar defined page 10 specifications page, 500 ns is the minimum period for almost all relevant parameters:

  Period of the CLK line semi

  Time between the CSn and the first edge of the clock

  The CSn pulse width

  Well, it makes sense of the clock of your 2 MHz.  You need produce waveforms of the following two, each cycle would be clock to 18 bits of data (12-bit encoder and 6 status bits).  The total duration of the cycle ends up being long 38 samples and would take 19 microseconds to execute (if updated to 2 MHz).

  CSn 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

  CLK 1 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1

  The actual binary data to write to the card depends on what lines you use.  For example, if you use p0.0 to CSn and p0.1 for CLK, table you would need to write would be the following:

  3 2 0 2 0 2 0 2 0 2 0 2 0 2 0 2 0 2 0 2 0 2 0 2 0 2 0 2 0 2 0 2 0 2 0 2 0 2

  The bits of the U8 number correspond to the 8 rows on the port.

  You will need an example of clock for your task source.  I suggest to use Freq Out on the 6251.  In DAQmx, it is programmed in the same way as a meter output.  You would set this up as a continuous meter to 2 MHz output.  Indicate on your task to use ' / Dev1/FrequencyOutput "as the sample clock source (not necessarily Dev1, but regardless of the name of your device).

  You would physically signal port thread 0 CLK in PFI lines and use it to sample a DI task so that you can read back your data.  You can enjoy on the falling edge of the CLK to allow 500 ns for the value to be set (the maximum duration of your sheet is 394 ns).  The only drawback to this is that you are not sampling the parity bit, but apparently not that it is a problem unless you plan to use it.

  Once you get the bits, you must translate that into an actual position.  When you call DAQmx Read, you will have an array of values.  The first value of each cycle is a disposable (look at the waveform to see why).  The next 12 items of any cycle would be the 12 data bits, next 5 bits of State.  As I mentioned earlier, the parity bit would not be sampled because of the decision of the sample on the falling clock edge (again, you can refer to the waveform to see why this is the case).

  You'll want to convert the 12 data bits of the table in a single 12-bit integer, then multiply by (360.0 / 4096) to get the position in degrees.  I don't know what development environment you use, but this type of data manipulation must be achievable.  For example, LabVIEW has a Boolean array of numbers feature that would be very helpful here.

  I hope that helps!

  Best regards
