Zenbook Prime SSD Tests: EXT4 Discard, Schedulers

Linux Kernel

The latest benchmarks to share from the ASUS Zenbook Prime are some quick tests performed looking at the performance of the Intel Ivy Bridge Ultrabook when its solid-state drive is tested on Ubuntu 13.10 with the Linux 3.12 kernel, then with the EXT4 TRIM/Discard option, and then running different I/O schedulers.

The ASUS Zenbook Prime UX32 features dual 128GB SanDisk SSDs. By default these SSDs are in a RAID array on this ultrabook but this testing was done of a single SSD outside of the array. The ASUS UX32VDA has an Intel Core i7 3517U Ivy Bridge low-power processor and 4GB of RAM.

Earlier this month I did some weekend disk benchmarks of this Zenbook Prime when looking at the Ubuntu 13.10 + Linux 3.12 kernel configuration with its defaults, then mounting EXT4 with the "discard" option, and then comparing the Deadline, Noop, and CFQ schedulers

These benchmark results from the quick comparison for you to analyze as you wish can be found on OpenBenchmarking.org via the 1312071-SO-SSDTESTIN58 result file. You can reproduce the Linux tests yourself using the Phoronix Test Suite.
