Say I have an Image model that stores x, y, width, height, and a thumbnail, then should I store the actual image data with a data: Data property or store a filePath: String and save the image data to disk? If storing in a Data var, from doc Data is only read when the properties are accessed so I assume the data is not loaded to memory directly; when reading the data property, is it the same underlying action as if we are reading from a filePath or would it be faster?
假设我有一个存储x，y，宽度，高度和缩略图的Image模型，那么我应该将实际图像数据与数据存储：Data属性还是存储filePath：String并将图像数据保存到磁盘？如果存储在Data var中，则只能在访问属性时读取doc Data，因此我假设数据未直接加载到内存中;在读取数据属性时，它是否与我们从filePath读取时的基本操作相同，还是更快？
Also for smaller sized thumbnail what would be the best practice?
对于较小尺寸的缩略图，最佳做法是什么？

In general (not just Realm), it is not a good practice to store binary data such as images in a database. Because binary data is not able to query or sort, So there are no advantages to use databases. It is a better practice to save the file path rather than binary data in most cases.
通常（不仅仅是Realm），将二进制数据（如图像）存储在数据库中并不是一个好习惯。由于二进制数据无法查询或排序，因此使用数据库没有任何优势。在大多数情况下，保存文件路径而不是二进制数据是更好的做法。
