![]() The write wear-out specs on SSDs and NVRAM devices generally are enough to heavily discourage patterns of usage that are not read-mostly. I would avoid your usage pattern purely for miserly reasons. However, given that spinning disks are often used in balanced read/write scenarios, a spinning disk buffering scheme might better support such a pattern than your SSD does.Ī side-note in case it is not obvious: I believe you are badly beating up that poor SSD. With a disk spinning (at 90+ revolutions/second), data fetching and data writing from/to separate tracks on the medium would likely be separated by movement of the flying head (aka "seeking") and waiting for the data to whirl around to underneath the head(s). ![]() 1 Your initial results demonstrate (to me) that the buffering system in the SSD is doing very little good for transfer speed in your balanced read/write usage.ĭoes it matter that this is an SSD and not a spinning disk? I believe that SSDs are highly optimized for lots of reading and little writing. To ship that database to users, you can include it as a flutter asset. Of course, you can also create the database programmatically by using a library like sqlite3 (or even drift itself). You can create a database with the sqlite3 CLI tool on your development machine. In the next step, find the desired SQLite location, which means it is located on the user machine. After that, cmd opens in the default folder of any machine. ![]() I want to be able to: save database entries to a text file on the device. First, we need to open the command-line interface that is the cmd from the start and type their cmd and open it. I have tried finding ways to go about that, but nothing so far that seems to fit my needs. Im now trying to figure out how I can save the entries to a Textfile. I would say the extra time was probably consumed getting data read out of the NVRAM devices when page reads within the SSD are largely going to waste because the SSD-level reads are interrupted by unrelated write operations. First, create the sqlite3 database you want to ship with your app. I working on a diary sort of app in Flutter. (Referring to execution times becoming comparable during experiment:)ĭoes this mean that when I did it originally most of the time it took was lots of separate disk reads? ![]()
