How do I check whether partitions on my SSD are properly aligned?
- by elementz
I just installed ubuntu on my new intel SSD. Now I am not sure, whether paritions are properly aligned in respect to my specific SSD.
Here's my fdisk output.
$ fdisk -l
Platte /dev/sda: 120.0 GByte, 120034123776 Byte
255 Köpfe, 63 Sektoren/Spur, 14593 Zylinder
Einheiten = Zylinder von 16065 × 512 = 8225280 Bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000a6294
Gerät boot. Anfang Ende Blöcke Id System

/dev/sda2 1913 14058 97558528 83 Linux
/dev/sda3 14058 14594 4300800 82 Linux Swap / Solaris
Also, do I still need to align my SSD at all, since I am using TRIM on the ext4 partitions by mounting them with the discard flag.
If it is the case, that my partitions are not properly aligned, what could I do to fix this without having to reinstall everything?
