Does Your SSD's File System Affect Performance?

Benchmark Results: Iometer 4 KB Random And Streaming Read/Write

The 4 KB random write testing really serves as a poignant reminder of FAT32's age. Considering what we saw in AS SSD and CrystalDiskMark, the results don’t come as a surprise. It is obvious that the flexible cluster size of FAT32 at large drive capacities becomes an issue for write operations. The 4 KB chunks have to be accommodated into 32 KB clusters. exFAT does the job much better than FAT32, although it may also have large cluster sizes. Since its free clusters are indexed, however, finding one is a simple matter of looking up the corresponding bit in the bitmap.

Again, the results on sustained throughput resemble those seen in our earlier tests, and there are really no surprises there.

    Those SSD drives.... *drool* Wish I could afford them.

    I remember the crossing from Fat32 to NTFS. It was significant even back then. Ever since I have craved a new file system offering to rekindle a fading memory of youth and joy. *sniff*

    NTFS was heavily based on HPFS (when MS and IBM were both working on OS/2). It even shares the same MBR partition type code.

    Enjoyed the article. Sadly, I am still unable to justify spending nearly a dollar per gigabyte for an SSD when HDDs are less than a dime per gig. Maybe when that price difference is a little bit closer.

    Agree with haplo. Wanted to see ext4 at least.

Maybe when that price difference is a little bit closer.120gb for a 120$ and HUGE performance increase and you still complain? How about you get a job.
