Help requested on Installing Linux on an unformatted SSD


Hello. I am an absolute beginner with Linux and would appreciate a bit of hand holding. I am building a small computer for use with Ham radio applications and have never used Linux before.

I have downloaded a Ubuntu build onto a wintel machine and created a cd. The drive in the PC is a CCD an I have only ever used one on a windows machine and then I didn't install it.

Can someone guide me as to :

1) how I should format or in some other way prepare the SSd for the installation of Linux
2) tell me anything I should be aware of in installing Linux to the SSD
3) anything I should watch out for in using the SSd with Linux.

That last one may seem silly but I have been warned never to defrag on the Wintel machine as it will damage the SSD.

I look forward to any help / advice that you may have.

Best regards

Nick (GW6EWX)

Just partition it as you would like, though putting swap on an SSD is not recommended, format it with the ext4 filesystem, & you should be good to go.
There is no need to defrag a Linux machine.
I think what they meant about defragging on your Windows box was that it is best to keep writes to disk down, but modern SSDs have better write balancing software on board the disks.

To expand on that a little, when you boot the CD, you will be offered the option to run as a "liveCD". This runs off the CD and doesn't update the hardware - but enables you to see if everything (video, network whatever) is supported ok.
There will be an icon on the desktop to install it. The installer will automagically format the SSD (just looks like a spinning disk). Probably best to go with the default install unless you have some reason not to.

Thanks again and thanks to LQ for enabling the forum.

Unless your SSD is older than 3 or 4 years I totally disagree with this statement. Wearout from excessive writing is a non-issue with modern SSDs and in case you really hit swap you want to have it on the fastest storage device available.
I explicitly recommend to put your swap on the SSD if you have a reasonably modern SSD.

The confusion meter needle sweeps to the right!

Hi again.

The SSD is a Vertex 450 128GB Bought a year ago and being used for the first time now. I don't know when it was manufactured.

Regards

Nick

Go with the default install - it will create a swap partition, which hopefully you will rarely use.
I have several systems using SSD for everything - swap included - and I fully expect (all) the systems to be junk before the SSD fails due to (over) usage.

Don't worry, be happy ...

Hi,

I agree with Tobi that your drive will suffice for daily usage and encourage a swap on the OCZ 'SSD'. You can tweak the install to get performance to match the 'SSD' hardware. Please consider a search here at LQ for 'SSD' optimizing/tweaking.

Please note that MTBF is not considered a good mark to follow yet it does provides some insight to life expectations for usage. Your OCZ Vertex 450 128GB has a MTBF of 1.7 million hours specified by the manufacture. The SSD warranty is 3 years. This 'SSD' specs are rated for 20GB/day of host writes for 3 years under typical client workloads. Look at TomsHardware review: OCZ's Vertex SSD Family Evolves, Again

Your OCZ Vertex 450 128GB utilizes the Barefoot 3.0 controller that is considered to use some kind of SLC emulation mode to enhance performance. You really have to dig into the specifications and data to understand how one can get the max performance from their Vertex series 'SSD'.

Personally, I would think modern Gnu/Linux should be 'SSD' aware since the move to solid state is evolving. Not all users are fully aware of the needs to how to configure the new technology. You really need to do your homework when a 'SSD' is to be used for a system install so that configurations are optimized to get the full abilities of the hardware.
Hope this helps.
Have fun & enjoy!

syg00 & onebuck thanks. OK I think I know how I am going to go with this now. Not had any opportunity to fire it all up yet but one evening in the week I guess. I will let you know how I got on.

Best regards to all

Nick
