## Storage

Hangfire 會將所有相關資訊會被序列化後保存到儲存區，如類型、方法或參數等。

儲存模型官方預設有以下幾種

<table>
    <thead>
        <td></td>
        <td>Sql Server 2008+</td>
        <td>Redis 2.6.12+</td>
        <td>In-Memory</td>
        <td>Price</td>
    </thead>
    <tbody>
        <td>Open</td>
        <td>✔</td>
        <td></td>
        <td>✔</td>
        <td>free</td>
    </tbody>
    <tbody>
        <td>Startup</td>
        <td>✔</td>
        <td>✔</td>
        <td>✔</td>
        <td>$500 / per year</td>
    </tbody>
    <tbody>
        <td>Business</td>
        <td>✔</td>
        <td>✔</td>
        <td>✔</td>
        <td>$1,500 / per year</td>
    </tbody>
    <tbody>
        <td>Enterprise</td>
        <td>✔</td>
        <td>✔</td>
        <td>✔</td>
        <td>$4,500 / per year</td>
