FIO (Zipfian) trace file for testing MiDAS code

<p>This trace is an FIO (Zipfian) trace file, designed for testing MiDAS code. It consists of 54 million write operations on a 4GiB block device.</p> <p>The format of the trace file is as follows: <br><strong><em>&lt;Time Stamp (s)&gt; &lt;Request Type&gt; &lt;LBA (unit: 4KB)&gt; &lt;Request Size&gt; &lt;Stream Number&gt;</em></strong></p> <ul> <li><strong>Time Stamp (in seconds):</strong> This is the time when the request is made to a block device.</li> <li><strong>Request Type:</strong> This is categorized into four types: 0 for READ, 1 for WRITE, 2 for NOT USED, and 3 for TRIM.</li> <li><strong>LBA (Logical Block Address, unit: 4KB):</strong> This represents the logical block address on the block device, with each unit of LBA being 4KB.</li> <li><strong>Request Size:</strong> This indicates the size of the request being processed.</li> <li><strong>Stream Number:</strong> This is used for multi-stream SSDs, but is not utilized in MiDAS.</li> </ul>
