SSD or USB Key?


  • The thing is: why should I spend 40€ without knowing if I'll have TRIM, if I can spend 25 for a 16GB SD card and a good usb3 adapter?If I was certain to have TRIM them 15€ can be worth, otherwise is just complicate things


    You have an Asrock H170M Pro4S logic board so you have a free M.2 PCIe slot don't you ?


    If you want something cheap and reliable why don't you buy a 16 GB Intel Optane SSD ?
    Those SSD were expensive but can be found new for ~20€ and have both an excellent endurance and reliability.


    A 16 GB Optane M10 SSD has a 395TBW lifespan while cheap 120GB SSD only have 40TBW lifespan...
    I can testify that a 16GB boot drive for OMV is a good choice : those devices are fast and ultra reliable, they make a perfect choice for OMV.


    Also I like a lot the fact that, once selected as a boot device, any NVMe device (as the octane) will always stay the first boot device.
    If you manage many SATA drive and have one as your boot device you can be annoyed with the wrong drive being selected as boot device and your OMV machine not booting...

    Those SSD were once expensive but can now be found new for ~20€. And Optanes drives have an incomparable endurance and reliability.

    I can testify that a small 16GB optane SSD as the boot drive for OMV is a good choice : those devices are fast and ultra reliable.

    This never occurs with NVMe boot drives... :thumbup:

  • when I created this topic cheap NVME weren't a thing. Also I would suggestagains a 16GB SSD since thing like plex will take a lot of space. 60GB or 120 are the best size since they come at nearly the same price.

  • 16GB is more than adequate for the OMV system. You don't want to put the Plex metadatabase or Dockers on the system drive anyway because you can never predict their growth.


    I started with OMV 2.x five years ago on a 16GB SSD. Even after upgrading it to 3.x, 4.x, and now to 5.x it still only uses 8.5GB.


    I will admit buying a few 32GB SSDs just in case things do grow to be more than 16GB, but this isn't going to happen anytime soon.

    RAID - Its ability to disappoint is inversely proportional to the user's understanding of it.

  • Not sure where you live, but I can't find a 16GB SSD anymore. On my build I have a 60GB because it was the cheapest one I could find at that time. Right now you can buy a 120 or 240GB SSD for 20/30€. Why going for the trouble to find a 16GB when you can just buy a 120GB?

  • I am in the US. I have been buying 16GB Samsung SSDS on ebay for many years. The last batch I got was a lot of three pieces for $18.00 shipped on November 30, 2019. There are still some to be had, but not at the price I paid.


    The reason I use 16GB drives is that I backup using dd which copies the entire disk, not just the used space. Backups are automated and daily and I keep the most recent seven days. At 16GB each the space needed to store them is reasonable. If they were 120GB each, it would not be reasonable to me.

    Maybe you didn't read my post and maybe you can't compare apples to oranges...


    Yes you can find 16 GB SSD and those are Intel Optane SSD, we don't quite speak about any low cost TLC SSD (or worse, QLC with a bad controller).
    Instead I am talking about intel Optane memory which is far more robust than QLC/TLC/MLC flash memory, even better than SLC flash in terms of life expectancy.


    I don't say that 120 GB SSDs are all bad..some have a pretty good lifespan like the Adata SU800 which has a 100 TBW capacity.
    But many low cost 120 GB SSD are cheap models which don't have a very good controller and they have "only" a 40 TBW lifespan, which may be too few in some cases with OMV.


    When you look for a reliable SSD, you may look at many parameters : its brand, its controller, and its "lifespan" given in TBW (TerraBytes Written).


    And I only say that if you can find brand new, Intel 16 GB Optane drives that have a 395 TBW lifespan for 25€ new in box with a 5 year intel warranty, well you may think about it, don't you ?


    You can even get new "system pulled" 16 GB optane drives for 10$ on ebay.


    I have build ~20 OMV systems in my life, some with low cost 30/60 GB SSDs which have run for 5 years and are dead because they have already worn out.


    If anyone ask me to choose between a SLC USB drive, a TLC 120 GB Sata SSD, or a 16 GB optane, I go for the optane..

  • 40TB for an OS are a lot. You shouldn't ever reach that limit in a normal lifespan of an SSD. Even in that case, you should recieve some SMART alert and be able to change the SSD in time.
