What is the smallest SSD I can get away with?

I'm planning on eventually buying an ssd for my laptop. I run Ubuntu and mostly just download a few pictures, and occasionally a Linux distro for other people. What is the smallest ssd I can use and not feel like I'm running out of space? 32gb, 64gb, 128gb?

 

Edited to ad, it is a Lenovo N585

Go for either 64Gb, or 128gb. Or you may wait, since the SSD market is still pretty new in the private hardware world; they're gonna get a lot cheaper in the future. You can get some pretty decent 64/128Gb SSD's for a reasonable price though.

I'm planning on waiting for a few months anyway. Just upgraded the RAM in my laptop. 

I do plan on keeping the hdd from my laptop and buying a case for it for extra storage if I ever need it. 

for the OS, I would use 64, but only in a desktop. for a laptop, I would go with 120. They fill up fast.

if you don't download much of anything you could get away with a 32gb on ubuntu, but i would still reccomend atleast a 64gb

personally i'd need 128 MINIMUM, 480 for gaming

It's a good thing I didn't buy one yet. I think I will get a 128 in the future. For now I guess I keep running with my 5400rpm hdd.

For OS system's I would go for a 64GB or a 120GB, The best SSD I have ever had in a price range is the Samsung 840 Series it is around £80-90 I highly recommend it if you do not want to spend a lot of money. I hope this helps.

Well, windows can run just fine on 64Gb, especially if you don't have a lot of heavyweight software suites.

I'm not sure but I think that even 32 will be more than enough for linux.

See, I had thought about that and I just wasn't sure. Don't Chromebooks have 16gb hard drives?

cromebooks also don't store anything locally. If you will always be on a network, and dont want to have any linux games or anything, that would be a good option.

The plan is to spend as little money as possible. If I can run my whole operating system on a 32gb ssd, then that would be awesome. I will probably buy a case to use my current HDD as an external hard drive. If I needed to store a bunch of large files I would have the room for it.

To answer your question definitively, For a linux distro (Ubuntu, in your case) With a few pictures and an external storage drive, 32 GB would be plenty.

You COULD run on a 16GB, but I would go 32, just in case.

Really cheap, decent speed, very nice reviews.

I'm not sure how you define "fine", but my Lenovo with a 64GB SSD has practically nothing installed on it and I still have to keep an eye on it not to fill up. Sure, it runs and all, but it's definitely an unnecessary annoyance.

I ran Linux on a 20gb hard drive for a long time. It was fine. It didn't fill up at all. Especially if you use an external drive.

I'm going to take a shot in the dark and assume that you are running Windows.

Seeing as I was replying to Dissentient's comment "Well, windows can run just fine on 64Gb", I don't think it's fair to call that a shot in the dark.

I was replying to Dissentient's comment "Well, windows can run just fine on 64Gb." I'm not saying a linux distro can't (my Kali is on a 30gb VM)

Back in the XP times, I had an 8GB HDD for years... it was horrible, but I even managed to have GTA SA installed, full install, nothing cut out of it, which is close to 6 gb...
But right now, on Windows 7/8 I need 40gb minimum and 60gb to be comfortable with my OS partition. You seem to be talking about 64gb as your only HDD/SSD in the computer though, in which case I have to agree, that is way under the comfort zone for Windows.
