Storage Devices Overview(存儲設備概述)
USB flash drives are commonplace today and have replaced floppy disks as the removable media of choice. They are small in physical size and large in memory capability, with the ability to store 64 GB or more of data on a single “stick.” They are popular and easy to use, since they don’t require a special card reader, because the USB device has one built-in. They are often formatted with the FAT-16, FAT-32, or exFAT file system and are ready to use straight out of the box. Simply plug the device into an available USB port, the operating system recognizes it, and you can begin copying, deleting, and modifying files.
USB閃存驅動器在當今很普遍，並且已取代軟盤作為首選的可移動介質。它們的物理尺寸很小，內存容量也很大，能夠在單個“棒”上存儲64 GB或更多的數據。它們很受歡迎且易於使用，因為它們不需要特殊的讀卡器，因為USB設備內置了一個。它們通常使用FAT-16，FAT-32或exFAT文件系統進行格式化，並且可以直接使用。只需將設備插入用的USB端口，操作系統即可識別它，然後您就可以開始復制，刪除和修改文件了。
Floppy disks dominated the removable storage arena until the late 1990s, and now they are nearly extinct in most organizations. While some removable USB thumb drives can store 64 GB or more of data, floppy disks usually only stored 1.44 MB of data. That means a single thumb drive can store the information from more than 60,000 floppy disks! Floppy disks used flexible magnetic media surrounded by a rigid plastic case. The most common floppy (shown in the bottom image) was the 3.5” floppy, which was named based on the diameter of the magnetic media inside the plastic case. It used to be commonplace to find a floppy disk drive on every computer, which was connected using a mini-molex or BERG power cable and a 34-pin internal IDE PATA cable. Contemporary machines typically do not have these drives, as they have fallen out of favor with the public. If you have a need for a floppy drive, one can be purchased for less than $20 that can connect to your computer using your USB port. Windows always reserves the A and B drives for the floppy disk drive (FDD), even if your system doesn’t have one.
直到1990年代後期，軟盤一直在可移動存儲領域佔據著主導地位，現在在大多數組織中它們幾乎已經滅絕。雖然某些可移動USB拇指驅動器可以存儲64 GB或更多的數據，但是軟盤通常僅存儲1.44 MB的數據。這意味著一個拇指驅動器可以存儲來自60,000多個軟盤的信息！軟盤使用柔性磁性介質，並由剛性塑料盒包圍。最常見的軟盤（如左圖所示）是3.5英寸的軟盤，它是根據塑料盒內部磁性介質的直徑來命名的。過去通常在每台計算機上都找到軟盤驅動器，該軟盤驅動器是使用minimolex或BERG電源電纜以及34針內部IDE PATA電纜連接的。現代機器通常不具有這些驅動器，因為它們已受到公眾的青睞。如果您需要軟盤驅動器，則可以用不到20美元的價格購買一個軟盤驅動器，它可以使用USB端口連接到計算機。 Windows始終將A 和B 驅動器保留為軟盤驅動器（FDD），即使您的系統沒有該驅動器也是如此。
