SSD CARE AND FEEDING IN UBUNTU OR LINUX MINT

NOTES ON UPGRADING TO AN SSD:

It is tempting to use a utility like the dd command or CloneZilla to transfer all data from a HDD to a new SSD. DON’T DO IT! You should backup your personal data and re-install the OS to the new SSD. Gparted or the Ubiquity Installer will format SSD’s with the proper partition alignment and optimize the file system (ext4) for the best performance. You may get less than optimal performance if you just clone the…

  1. Joe, a neat trick I learned from the people at solus-chat on IRC, you can make your machine yet more snappy by having /home on the SSD and linking music, documents, downloads etc to corresponding folders to a hard drive. That speeds up a lot of session-specific stuff such as config and profiles

  2. After watching this, I went and checked, seems like my 250gb Samsung 840 Evo (bought in 2014) had a total of 9 terabytes written to it. Dang I need to stop distro-hopping!
    I was a bit scared when I bought it with all the TRIM maintenance and care, but it seems it's doing just fine. Maybe I was lucky? By the way joe, SSDs run NAND flash instead of EEPROM.
    eeprom reads/writes byte per byte, flash can't, it does it by block

  3. Joe, I would look in to the "relatime" mount option as an alternative to not using the "noatime" mount option.

    The Linux developers have come up with the "relatime" option as a better solution to the "noatime" mount option. I would suggest anyone using a SSD use it if it hasn't already been enabled by default. I hope I never have another computer with a primary HDD. The first time I upgraded a laptop from HDD to SSD the performance was dramatically different. Since then I always plan to use SSD on any computer system disk. Where cost vs performance is not needed I will always use HDD such as backups or ancillary data.

  4. Thanks for interesting and useful for Joe. Like you I was wondering how much longer my old drive would last in a 7 year old Samsung laptop so I fitted a Samsung SSD which supposedly are built to last with the extra 'headroom' to extend data writing. Apparently the benefits are somewhat reduced with old hardware because of data transfer via sata 2 and not 3 but is still works great. Are the optimisation features you refer to unique to Ubuntu and derivatives or are they also in Manjaro and my Fedora 27 installation I wonder?

  5. For a person to confess in 2018 that he just recently decided using SSDs instead of HDDs is quite something, Joe!
    To say that SSDs are going to "probably" outlast HDDs is like to say that planet Earth is "probably" orbiting Sun and not the other way around 🙂
    I knew you tend to kind of like the outdated but new and inexpensive "junk" hardware but doing this to such an extent is seeming truly extraordinary to me 🙂 Thumbs way up, man!

  6. You are not the only one I am using a Crucial MX100 256GIB SSD and the 3TIB for the data disc, I would like to mount the data drive permanently mounted but still able to access my data, what he is trying to say is if moving to SSD then use the SSD as your boot drive and install the OS onto the SSD using the installer. if your computer has 8-10 SATA ports you might want to use 8 of them in a RAID 10 mode with 8 100tib Data-Centre SSD's and the free SATA ports can be used for a boot disc and a Blu-Ray drive, that works for me. you can get the really large SSD drives but will cost you a bit, what about a 100TIB Data-Centre SSD and you will have plenty of room.

  7. Thank you. Very Helpful.
    A question (if you know): What about the software Samsung shipped with their drives. I installed one in my Dell Vostro laptop, (Years ago) using that software to transfer everything. Do you know how that package manages memory allocation, as compared to the process you are recommending here? I was delighted with the speed improvement, and longer battery live, at that time, and have had no problems, but now I wonder if it would have been even better had I done it differently. (That system is a Win7 system… not migrated to Linux yet).

  8. Thanks for this video Joe. I have two external SSDs (one from Samsung and one from ADATA)….

    Long story short the Samsung T3 SSD has had no issues with partition misalignment…

    the ADATA SSD, it well…said the the drive was misaligned…so I have to realign that drive to ensure better performance. And yeah it says it's gonna take an hour to 2 hours (it's connected via USB 2 though so that does make sense).

    Note to self: Stick with high quality Samsung SSDs.

    ADATA SSD cost me $69.99

    Samsung T3 SSD cost me ~$160.00

    So…you get whatcha pay for. Samsung and their owned affiliates are who I trust for my OS. Right now I'm gonna use my ADATA SSD as a screenshot storage drive for my Xbox One. Especially since within a month of getting it the health of the drive dropped from 100% to 80% (found via hard disk sentinel linux command line utility.)

    So yeah… ADATA (also known as VectoTech) is NOT a reliable vendor for SSDs.
