128gb flash drive filesystem best partition

Total data being written and read from the disk for each run was 2GB. I ran the tests with block-size as 4K initially, but then discovered that changing it to 4M was giving me better throughput. The results are summarized in a table at the end. Sharing the screenshots of the Netdata dashboard highlighting the disk I/O for tests run on my laptop (the control).įor tests run on the Raspberry-Pi I was also looking at CPU, Temp and Disk I/O. ext4Only, ext4Luks, btrfsOnly, btrfsLuks). I wrote a script that would perform a write test, followed by a read test on each of the 4 partitions going serially (i.e. # sudo fio -bs=4k -rw=read -direct=1 -ioengine=libaio -size=2G -name=test -iodepth=64 -filename=` I already know that btrfs is going to be slower that ext4, I just want to know by how much. I want to test full disk encryption using Luks along with these file-systems. I want to test two file-systems btrfs and ext4. Then filesystems are built on these partitons. One is a 128GB SanDisk USB pen-drive, the other is a Seagate 5TB Backup Plus external 2.5 inch HDD.Įach drive is partitioned into 4 partition of equal size. I will also use a SanDisk 128GB USB drive and measure its performance just for fun.

The test will be done on my laptop which will be the control, and then on the Pi I will be running an entire set of different tests which will look at CPU and temperature as well. I want to run btrfs as it makes adding new drives to your setup very very easy. My main concern is that the Raspberry is too low powered to run an encrypted btrfs setup. I want to run an encrypted setup and I also need a way in which I can just add new drives later on and not have to repartition the entire thing. In this Benchmark I will be comparing the performance of the HDD in various filesystem configurations on the Raspberry Pi. What is Block Size? Why is it so important ?.Before installing it on my server I wanted to run some benchmarks on it. The computer will the the Raspberry-Pi which I already have. I am going to use this for my home-server build. I bought myself a 5TB external Hard-drive from Seagate.
