I have Debian Gnu/Linux as My current Desktop Operating System for many years now. this will be My first SSD experience.
I am confused to choose between sf-2281(Sandforce) Intel 330 series 120GB SSD drive and Crucial M4 drive.
I hope performance can be restored to pristine condition(~100%) by TRIM,Garbage collection in Sandforce based SSDs? I read a claim in a review and shown this(below pic) as how TRIM fails to improve performance.
* I use a Debian repository which have daily updates like 30-50MB or sometimes more. even if I delay the updates for a week, it will add to some amount. These packages are downloaded,extracted and installed. Will it wear the system more than Windows 7/8? Is it better, if I choose a Linux distro with lesser updates?
* I've read about SSD alignment is needed. How to achieve this? I plan to keep "/"(root),"/boot" partitions in SSD and "/home"(Home directory) in Sata HDD. is this the correct strategy?
* I've read that wear levelling with TRIM enabling in Operating Systems. Since I may be using ext4 file system, will adding some paramaters to /etc/fstab enough(like "discard" option). I read that a cron job running weekly for garbage collection is better recommended(elsewhere).
* For Gnu/Linux- Which one is more recommended SSD's based on controller chipset: Sandforce or Marvell? Note that Currently, I chose "Crucial M4 64GB" drive for reliability. I need the most reliable, yet vfm( ) drive since RMA/Warranty is a issue sitting in India.
* I am using a primitive Zebronics 450W PSU for many years now. Will I need to replace it? Mind this is a C2D E4600 system with 2 GB ram.
* I am buying from USA to India, since Crucial or most of the SSD brands are damn expensive here. So, If I buy from USA, is there any brands like Intel which will honour warranty on SSDs Internationally(means in India)?
I think that you have gotten some bad advice. Unless I am wrong, and I am frequently wrong,
- You have to be careful to get a distro that will support the TRIM command. If I read correctly, here's an old post on how to do a practical test: http://duopetalflower.blogspot.com/2010/11/enterprise-k...
- Go ahead and do updates to the drive. You bought it to work for you. Make it work.
- Alignment is either supported by the distro's installation process or is not there.
- You don't run garbage collection on the drive, it runs it itself when it has idle time, or when it runs out of writeable space.
- An SSD will only add a few watts to your draw, so power should not be an issue.
- I don't know about international warranties.
Unfortunately, this is a forum mostly for Windows users. Your questions are specific to Debian. Any Debian users with SSDs out there?
