Linux 3.8 File-System Testing From A SATA 3.0 HDD
Phoronix: Linux 3.8 File-System Testing From A SATA 3.0 HDD
Most often when carrying out any Linux file-system benchmarks -- or really, any benchmarks in general -- on Phoronix it's using solid-state storage. SSDs are just too great to pass up with their incredible performance. However, for those still using rotating media, here's a collection of file-system benchmarks from the new Linux 3.8 kernel when tested on a Serial ATA 3.0 Western Digital hard drive.
Yep, HDD tests are importent
I use Ext4, but...
"The EXT4 vs. Btrfs file-system comparison was more competitive with a Serial ATA 3.0 hard drive
compared to recent SSD file-system comparisons."
Comparing to the SSD (only) tests here
where on SSD Ext4 trounced BTRFS by a factor of 4 times, on the HDD BTRFS was faster than Ext4 by 14
percent. That's an enormous difference that is VERY important to people using multi TB (I was just
reading a dicsussion thhear where one of the members was managing 9TB through 130 TB systems) file
systems where SSD is not an option - especially as new research indicates spinning disk storage is
to go through yet another leap of capacity in the next few years.
"In the end the results were mixed between which Linux file-system was faster depending upon the
Are you kidding, in these tests BTRFS beat Ext4 in 9 out of 14 tests and was only significantly
behind Ext4 in the PostgresSQL test, which has historically been a problem case for COW file
systems. It's a shame that the SSD tests didn't include the PostgresSQL test, it would have made
comparison a bit more interesting.
In short, BTRFS was significiently behind Ext4 in one out of 14 tests and beat Ext4 in 64% of the
Great to see HDD benchmarks - they're truely useful, keep up the good work.
