    SD or XQD

    ive searched and not really got the answer im looking for.
    Yes a XQD card would be nice but man are they pricy.
    will the camera suffer buffer issues on high speed shots just using a SD card of the correct capacity and speed or am i better biting the bullet at purchase and getting a XQD card ?

    SD or XQD
    This comes from the link that Fred posted. Lexar tested some of their own cards. I have no idea whether a different brand of SD card would perform better than a Lexar SD card.

    I don't have an XQD card in my D500 and I don't notice any buffer issues.

    The most important difference is reliabilty. SD are very old tech in the bus system and lacking error detection or correction. They are phyisiclly weak besides being electically weak.The bus they usewas designed for only floppy disk drives decades ago and was selected for cameras solely to the very low manufacturing costs.They were never intended for critical work and the only reason 2 slots were added to higher end cameas was to try to reduce the risk of bad dats getting written to storage. Cameras not intended for paid work were considered a good compomise.Some cameras sequencially write to the first then the second card is written from the first.Sony does that so they have different speed buses and different style of card so they are no bettter than single slot since if there is a write error to card one,the second card gets the same bad data.
    XQD was designed from day one to be the first pro format card system and is far more capable mechanically and electronically. They have the ability to map out dead or questionable memory addresses.They also have error detection and correction. Their protected unexpoed contacts are a design that is much more reliable and long lasting.
    Even Sony admits the XQD is far more reliable and published white paper which rated them 2 orders of magnitude longer Mean Time Between Failure better than 2 mirrored SD. They reserve XQD for their professional video ENG cameras where reliability problems could result in missing events worth millions of dollars.But those cameras start at about $25,000 and go up to$50,000 How many slots for critical work? One, and not one pro cameraman has mentioned concern. Sony stated that of the first first million sold, they only had one returned for warranty replacement..
    We have all had lost work due to bad SD cards.
    If someone is doing work for hire they will start losing out of gigs if they only have SD in one time only events.

    If you don't shoot in bursts of 20-30 images and more then you'll never notice the buffer not clearing fast enough. I've gone 315 images in Ch mode in testing with a XQD card (it stops automatically at 200 but you can immediately start again - it's a feature that prevents infinite shooting in case something lies on the button). I don't know that I ever hit 40 with my fastest SD card. That said, there are now some ultra-high speed SD's that are about 2/3 as fast as the XQD cards, but they cost about the same as the XQD card so it's really the speed you're paying for, and for the same money the XQD card gives you both better performance, reliability, and durability.

    FYI, I used a 64GB 95MB/s SanDisk Extreme Pro in the tests I mentioned. It's what I use in my D750.
