Installing Ubuntu on a SSD


Before beginning I downloaded an iso for RedoBackup and created a bootable CD. I booted that my system with that CD and backed up my two Ubuntu partitions to a USB drive.

Then I opened up my case and added my new SSD as a second drive on my system and formatted it with Gparted. To get the alignment right I did two things:

Unchecked the box that says “align to cylinders” Left 1MB of free space *before* the new partition. This results in an offset of exactly 2^20 bytes or 2048 512B disk sectors, which is excellent alignment for virtually all applications, SSD types, RAID array stripe sizes, etc.

Then I created two partitions one for the root file system and the second for home. I made both just slightly larger than the corresponding partitions on my current system disk. Note I did not create a swap partition, I put that on a spare hard disk to minimize wear on the SSD. Finally I set the boot flag on the root partition.

Next I rebooted to a Clonezilla cd and...

So I have this 128 GB SSD and a 1 TB HDD. And I plan to install Ubuntu on this system that uses them.

Now all the info that I have found in here about similar problems, are usually with limited SSD space, but mine is pretty big. It is a Samsung 840 Pro 128 GB.

So my question is, what would be the intelligent way of partitioning my system in this case?

Obviously the / will go on SSD. Then /home and /swap will go on HDD. But what else? Should I care about "/tmp" and "/var" also and move them on my HDD? How much size would it be smart to allocate for them then?

I'm running a similar system at home. I've got a 256 GB SSD with ~ 90 GB allocated to linux. Even with a 15 GB game on the SSD, I've still got a lot of space left over. So basically, you probably don't need /home to be on a separate HDD.

/tmp you can likely just leave on your SSD without giving it its own partition. /tmp is cleared on every reboot. Giving it its own partition with a fixed size...

This article explains the steps for the installation of an SSD device on an existing Ubuntu desktop PC.

Disk Performances

First of all, let's have a look at the disk read performance with the hdparm utility. The desktop PC has three disks, /dev/sda being the new SSD device (an OCZ Vertex 2 SATA II 3.5" SSD).

$ sudo -i hdparm -t /dev/sda /dev/sdb /dev/sdc

The three disks have the following performance:

sda: OCZ-VERTEX2 3.5 229.47 MB/sec sdb: WDC WD3000GLFS-01F8U0 122.29 MB/sec sdc: ST3200822A 59.23 MB/sec

The SSD device appears to be 2 times faster than a 10000 rpm disk.

Plan for the move

The first step is to plan for the move and define what files should be located on the SSD device.

Identify files used frequently

To benefit of the high read performance, files used frequently could be moved to the SSD device. To identify them, you can use the find command and the -amin option. This option will not work if...

I purchased a computer a while back and installed Ubuntu on the HDD. Everything was cool until I noticed a Slickdeal on SSDs and had to purchase a ~460gb drive.

This was last year. I’d been meaning to switch my booting to the SSD, but never got around to it. After all, I leave the PC on pretty much 24/7.

Then I started playing with some stuff and decided I wanted to decrease disk IOs, so tonight I moved my installation from HDD to SSD. It was a little involved so I figured it might be nice to document it here for future reference.

A general outline is as follows:

Erase the SSD, and ensure it is large enough to fit your entire ubuntu installation. Partition the SSD so as to mirror the HDD. In my case, I had to create a GPT partition table using GParted, add an ext4 partition for my actual files, and a swap partition. Boot into a live linux install, mount the drives, rsync the necessary files. Restore grub bootloader using a series of arcane commands. ...

The idea of splitting your Ubuntu installation between two hard drives is a concept that isn’t new. The idea often comes up from those that are looking to spread out one Linux installation onto different hard drives, for many reasons. One of the main reasons users split Ubuntu is to compensate for the small sizes of solid state drives, For example: when you have an SSD and a large 1TB 7200 RPM drive. You want to benefit from the break-neck speeds of an SSD, but you realize it’s small. That’s when you realize that you’ve also got a large second hard drive. With this method, it’s possible to split half of the Linux installation onto the SSD, and the other onto the RPM one.

In this tutorial, we’ll focus on Ubuntu, as the installation tool is the most straight forward, and easiest to understand when it comes to splitting up an installation. That said, the basic concept is easily repeatable on many types of Linux distributions (both complex and beginner ones).

Yes, absolutely. And UEFI makes it even simpler. When booting the Ubuntu boot disk, select UEFI instead of MBR. Also, in the bios, you might have to disable "enable secure boot", or something like that. If you already have Windows 10 on in, from Windows 10, open the disk manager, and shrink the partition that windows 10 is on. And when installing ubuntu, install on that free space. With windows 10, you probably have 2-3 partitions already. A UEFI boot partition that's about 500 MB, a primary partition, and maybe a recovery one. Shrink the primary one, largest one, maybe called C:.

The Ubuntu installer will detect (it will tell you it did, if not DANGER), and write on the UEFI boot partition to let it know you have more then 1 OS. After install of both, when you boot, you will have a few seconds to choose which OS to choose. And if not, go back to the BIOS, and you will have the option there.

Windows 10 tries to stop the installation of any other OS, that's why they...

An SSD (solid-state drive) is one of the best investments you can get to speed up your system. If you already have a quad core processor and four or more gigabytes of RAM, this is the next step for upgrading your system for maximum performance. Your system can only run at the fastest speed of it’s slowest component, and for most computers these days that’s the speed that the hard drive can read and write data. An SSD can really crank this up. How much improvement can you get? Well, my system went from a boot up time of 116 seconds to just eight seconds. So without further ado, here’s how to get the best bang for your buck tuning Linux for SSD performance and long life.

First off, don’t throw out your old HD! Or if you don’t have one already, you should get one for file storage; external or internal, it really doesn’t matter. You’ll need it because (1) SSDs work best in conjunction with a regular platter-based hard drive for various technical reasons and (2) for file storage....
