Question about MBA storage

[3lite]

I have a 2012 MBA Air 13 128Gb storage.

I am fine with 128 storage as I mainly use a laptop for school purposes and what not.

But if somewhere down the line I may need more memory...

1. Are the OWC SSD for MBA as good as the ones that Apple uses?

2. Would a external HD suffice and what are its disadvantages (besides having to carry it) since it isn't SSD?

3. Do you guys know of any good external HD for MBA? I'm looking to mainly store music, photos, etc.

Also, how much Gb storage should I leave free at all times to have optimum performance? About 30Gb right?

Thanks.

Yes.

You can buy an external SSD or HDD.

Any external drive will work, as long as you can connect it.

Generally speaking, it's good to leave at least 10% of your internal drive free. More is better.

I read on here the owc gave a MBA owner issues on the actual size and fitting of the drive.

Might want to check for that thread OP. I have the 512 apple drive so I cannot speak with any knowledge on the matter.

Man it's so crazy to me how little space is actually usable when you think about it

128 GB SSD is what is on the box

120 GB is the actual size of the drive

20 GB is used upon first set up of Mac

You have to leave about 20-30 GB to keep SSD running smoothly

So essentially you are given about 75 GB of space that you can actually USE. You get a bit more than half of what you think you are buying. Insane

it's long been known that both Apple and PC makers state the unformatted capacity of their drives - formatted capacity is always a few % less

20 to 30gb of free space for an SSD drive to run smoothly? - I don't think that part of your statement is correct.
and actually initial setup of the OS X - the installed Applications, System and Library Folder should total less than 15gb - plus how many additional apps you want to install of course.
you can always delete the stock ones you are never likely to use.

and if one still ain't happy, then pick up a 500gb external HDD for $80 for the excess data.
the basic 13" Air with 128gb SSD is still fantastic value for money when compared with anything the opposition has to offer when everything's weighed up

Multiple people have stated it's true. That you should leave somewhere around that area free at all times or your SSD will experience undesirable results

No. When I first bought my 128 GB MBA the first thing I did upon set up was check how much space I had left. It said something like 99.XX out of 120.47. My MBA came with 10.8.2 so it's possible it uses more space than previous versions.

Yeah I saw that. I think they definitely made a mistake on his...

Is there a difference? I've heard SSD is quicker but I'm not sure what they exactly mean by that.

Yeah, I know! I just hope with each future update to the OS it's still 20 GB and not more.

Yes, a SSD is much quicker, makes no sound and has no moving parts. A HDD has a spinning disk which makes noise and has much slower read/write performance, by comparison.

Since it's external would it really be that big of a difference? Since it's going to be limited by the USB and all.

Thanks.

I'd aim for about 20-30GB free most of the time also.

Why?

- temporary storage space for patches
- space for OS X to use temporarily for on-the-fly file defragmentation
- space for hibernation file, swap, etc.
- some space to keep local time machine backups of files in between your regular time machine backups


Yeah, sure - you CAN fill up your disk. But you lose functionality (time machine local backups), cause problems with upgrades, etc.


This is why i believe the 64GB MBA is a total waste of time and shouldn't be sold (IMHO it only exists as a cheap entry price to up-sell to a higher model once the user is interested). 128GB is limiting enough, and for a machine that "just works" the user shouldn't be constantly paranoid about free space...


IMHO - serious use with a 128GB air (or hell, any machine with an SSD really - they're all too small for the price) means you "need" some sort of home storage (NAS) that you can keep your long term storage on so you're not constantly scrimping for storage or considering what to delete - and use the 128GB flash as short term storage for "current" data.

I agree with your values. Anything less than those amounts impacts real world performance which gets annoying fast. Based on my first hand experience 256GB is optimum on the minimum end of things, and I believe Apple does too. It's just a shame they charge a huge premium for it.

[throAU]

Yup.

256GB is enough to compromise a bit and have some music, movies, data, etc on your machine without constantly needing to store on external disks.

128 can be done, but it is a bit painful.

64gb is a joke

Can anyone explain this to me?

Look at the finder available storage.

WTH is this backup under system storage pane?

What you are seeing these is space taken up by Time Machine's local backups. You can ignore it and OS X will manage the space and shrink it if the space is needed. If it is bothering you, you can turn Time Machine off then back on and the space will be wiped.
