    BEWARE OF FAKES! YELLOW LOCK TAB? RETURN IT!
    ***Second Purchase (FAKE Card) - May 2018***As you can see below, I purchased the first card from this same listing on Amazon and it was real. Unfortunately a year later I purchased the same card from the same listing and now I received a fake. I noticed the box had some hard to read print on the back, but didn't think much of it. Then upon opening the card I noticed that the locking tab was yellow, not grey like my first one. Upon even closer inspection, I noticed that the new (fake) card didn't have a batch/serial number on the back, and was missing the "Made in China" engraving. Once formatting in my camera and testing, I noticed that the card easily took 10 times as long to write a photo to. Also, the camera was saying that the new card had a higher capacity. As I am using these cards in a Sony A7Riii, and the fact that it takes 100MB 43MP photos, I require high speed cards, hence why I purchased the fastest UHS-I card Sandisk makes. Amazon in the past has provided real cards, but in this case it was fake! To the untrained eye or average consumer, most will not notice this until they have VERY poor performance from the card, and may think it's their camera, device, etc. See below for test and comparison photos.***Original (Real Card) - June 2017***I used this card in my Sony A6500 for about 8 months shooting about 20,000 RAW images without a single issue. I've now upgraded to the Sony A7Riii and am getting great read/write speeds in-camera with it. As some may know, the camera has 2 card slots: one UHS-1 and the other UHS-2. UHS-2 supports triple the speeds over UHS-1, which is what this card is. I still get more than acceptable burst rates before the buffer fills. I see no reason to ugprade to the twice the price, half the size UHS-2 cards for this camera.

    【速度について】
    CrystalDiskMarkでベンチマークテストを実施しました。
    シーケンシャルの速度はスペック通りですね。
    ただwin7の環境でのベンチマークです。win8.1以降だともっと速度出るはずです。
    シーケンシャルライトは91.65MB/sですね、ビット計算だと733.2Mbpsになります。

    【品質について】
    Check Flashで全セクタをチェックしました。
    ちゃんと256GB使用でき不良セクタもありません。
    当然ですが本物ですね。
    メモリーダイレクトが販売し発送はAmazonでした。

    windowsのディスクの管理を見ると、未割り当ての領域が32MBあります。
    何それ?怖い!何て思いますが、これはSD3.0の仕様ですので気にしないでください。
    exFATのフラッシュメモリは全部こんなものです。

    【非常時にはDISKPARTで修復】
    全てのフラッシュメモリに起こり得る事ですが、ライトプロテクトが掛かり書き込みも削除も出来なくなることがあります。
    SD特有のプロテクトスイッチではありません。使用方法によりますがmicroSDでもたまに起こります。

    フォーマットソフトの相性とかドラレコのデータ保護機能とか、理由は様々ですがライトプロテクトが掛かります。
    「なにこれ不良品?」「壊れたー」と言って捨てる前にまず直せるか試しましょう。

    windowsにはコマンドラインから使える「DISKPART」という機能があります。
    DISKPARTの「clean」コマンドでライトプロテクトが解除できますので、非常時にお試しください。
    ※データは確実に消えるのでやる前にバックアップしましょう。
