I just installed Elementary OS (Ubuntu 12.04 based) on my Samsung 840 Pro (128GB) using GPT and aligned all the partitions. After installing Ubuntu, I modified the Fstab to add noatime and discard.
The strange thing that i'm noticing when I run hdparm -Tt is how slow the cached read and disk reads:
/dev/sda:
Timing cached reads: 6290 MB in 2.00 seconds = 3145.90 MB/sec
Timing buffered disk reads: 754 MB in 3.01 seconds = 250.81 MB/sec
Which is odd since I saw hdparm results for the Samsung 830 on archlinux:
https://wiki.archlinux.org/index.php...SUNG_830_128GB
# hdparm -Tt /dev/sda
Timing cached reads: 22130 MB in 2.00 seconds = 11080.54 MB/sec
Timing buffered disk reads: 1500 MB in 3.00 seconds = 499.38 MB/sec
Anyone know what could be causing this?
