Which SSD is the fastest (2012-2013) ?

For SSDs that have been released in 2012 or 2013, then it doesn’t really matter, almost all SSDs perform similarly in real world applications.

If you are booting windows or running games or doing some work on virtual machines, all will perform the same, and no one will notice a difference in speed, since all today’s SSD are fast enough to saturate what the processor can handle.

Why is Power-on-hours SMART attribute not increasing on Intel or Sandforce SSD ?

After running some drives for a whole day, I noticed that power-on hours (SMART attribute 09h in some drives), has only increased 2 hours, which is really strange, so, I checked a manual for an Intel SSD, to find what does the SATA SMART attributes means exactly, and found this:

09h Power-On Hours Count

The raw value reports two values: the first 4 bytes report the cumulative number of power-on hours over the life of the device, the remaining bytes report the number of milliseconds since the last hour increment.

The On/Off status of the Device Initiated Power Management (DIPM) feature will affect the number of hours reported. If DIPM is turned On, the recorded value for power-on hours does not include the time that the device is in a “slumber” state. If DIPM is turned Off, the recorded value for power-on hours should match the clock time, as all three device states are counted: active, idle and slumber.

Install Ubuntu or Linux Mint with Btrfs disk compression enabled

This is a guide for installing Ubuntu or Linux Mint with full file system compression enabled, on a BTRFS partition.

This guide is intended to be simple and not for advanced users.
For beginners, this guide will take less time than other advanced guides.

This is useful in case you have a storage device with limited space, like an SSD, or you just want few extra GBs.
