Hi there,

I replaced my hard drive with SSD for faster load time and power saving, I did exactly the same I did with standard hard drive to the SSD in partitioning and installation, but I read that most Linux distro handles SSD and HD differently. As far as I know reducing the write cycle to the SSD will protect it from premature failure, the same way to protect USB thumb drive in portable boot etc., but how actually the OS handle the two media during installation and use, say for example on Debian ?

you can easily search for related info on the net (for example):

It is not the OS, but the kernel itself (which is more or less independent from the OS). And especially it depends on the mount options mainly.

joboy,

As of Ubuntu 14.04, scheduled TRIM is enabled by default for Intel, Samsung, OCZ, Patriot and Sandisk SSDs, so there is no need to use discard.
NB For some Linux distros and other SSD manufacturers it may be necessary to manually run fstrim occasionally.

Here are three articles about using fstrim, which may be useful:

Just to add to beachboy2's reply above:-

For those of you (like me) who are running IDE/PATA spec SSD's on really old hardware - (without SATA interfacing), the fstrim command often isn't supported by the older standard.

There isn't much you can do about optimization, but you can implement a form of 'rubbish collection' manually. When setting-up one of this type of SSD from scratch, leave around 8-12 % of the total capacity unformatted.

By doing so, this gives the drive controller room to manoeuvre; it has somewhere to place 'full' blocks as they're rotated out of service, deleted, then marked as 'ready for re-use' again by the system.

This can also be done to an 'in-use' drive; merely giving the drive a percentage of 'blank canvas' to play with will work wonders for its lifespan. It must be remembered, however, that all SSDs today have vastly extended life-spans compared to their older counterparts.

For IDE/PATA SSDs, I have no hesitation whatsoever in recommending Transcend drives. Fairly new to the domestic sector, they formerly supplied rugged, all-weather drives to industry for use 'on-site', often for mobile, 'go-anywhere' machinery.

The reliability is awesome.....and the build quality is a thing of beauty.

Thanks for the tips guys, I always think solid state drives are not as reliable as magnetic drive, electronics failure could lead to totally lost, where magnetic drives can always partial recover. I remember the SanDisk USB stick I bought years ago, it suddenly failed one day completely disappeared from the computer, but it came back after a while, it is very unreliable, so even these days I still limit myself to 32G, SSD maybe another story.

a magnetic drive also may die without the possibility to recover anything - or just that will cost too much.
Actually I had a disk where the software on the device went into deadlock and could not be recovered. This was a bug, which was later fixed, but that did not help on my disk.

Transcend is one of the largest manufacturers of memory in the world. It has had offices in the USA since 1990. I can't remember long enough ago when Transcend didn't market to consumers.

But they might not have marketed SSDs to the US consumer market until recently.

If you just let the drive sit idle, without powering it on, the HDD type will retain data much longer than the SSD type.
