Which won't matter on SSDs

• wongarsu 4y ago
  On all the benchmarks of SSDs I've seen they perform 1.5 to 4 times better on sequential reads than on random reads. That's a much better ratio than HDDs, but still enough to care about it. You're also likely to get less write amplification if your swap file is continuous. Of course with all the layers of indirection it's a numbers game, you don't know if your file system allocates adjacent inodes, and you don't know how your SSD will remap the blocks. But all else being equal, trying to make the file as sequential as possible seems preferable.
