Is the 256GB flash storage enough for me? Can I install a bigger SD?

Question

Hi there, I am transferring from a Dell (which I love) to the Macbook Air 256.  However, I'm very concerned about the storage. I've had my Dell for 10 years and never gotten near the storage capacity. It has 285Gb and I've used 215GB of it. I figured the 256 would be enough, but I've only transferred 1 year of pictures over to my MAC, and the storage space is already HALF FULL!!!! I barely deleted 50 photos, and you can see the storage space free up by a couple GBs. Does flash storage not hold as much as regular hard drives? I'm a novice at mac computers and am getting really frustrated that this computer might not hold anything. Everything is also on an external drive, but I like it all on my computer for easy access.  I also heard that I can put SD cards into my Macbook air to give me more storage. Is this true and if so, where do I get that? Thank you so so much for your help!

Answer 1

firebox is only $30 at walmart, if you dont have a safe deposit box.
theft is more about HIDING IT than vaulting it, buy a fireproof SLEEVE on Ebay for $30 and hide it under etc etc something, very easy to do.
you can buy your own private website, which is what I do, I have several   Cost is roughly $120 per year unlimited storage..
(see godaddy.com or otherwise)
However safety has to be put in place to prevent others from accessing your data, also very easy.
Its all about redundancy #1  and #2 longevity (DVD professional archival) for very important information that cant degrade over short term and rated for at least 60+ years.
All these points are explained in detail in the link I posted you as User Tip.
Online archives
Drawbacks:
1. Subject to server failure or due to non-payment of your hosting account, it can be suspended.
2. Subject, due to lack of security on your part, to being attacked and hacked/erased.
Advantages:
1. In case of house fire, etc. your data is safe.
2. In travels, and propagating files to friends and likewise, a mere link by email is all that is needed and no large media needs to be sent across the net.
3. Online archives are the perfect and best-idealized 3rd platform redundancy for data protection.
4. Supremely useful in data isolation from backups and local archives in being online and offsite for long-distance security in isolation.
5. *Level-1.5 security of your vital data.
As for hard drives, dont make the HUGE mistake others make, only having ONE off computer copy on a HD, thats a tragedy in waiting,  2 copies is 1, and 1 is none, ....and the data on the computer doesnt count in the 2-copy scheme.
Hard Drive Warning (all makes and models)
Ironically but logical, new hard drives are far more fragile than one that has been working for several months or a couple years. So beware in your thinking that a new hard drive translates into “extremely reliable”!
Hard drives suffer from high rates of what has been termed "infant mortality". Essentially this means new drives have their highest likelihood of failing in the first few months of usage. This is because of very minor manufacturing defects or HD platter balancing, or head and armature geometry being less than perfect; and this is not immediately obvious and can quickly manifest itself once the drive is put to work.
Hard drives that survive the first few months of use without failing are likely to remain healthy for a number of years.
Generally HD are highly prone to death or corruption for a few months, then work fine for a few years, then spike in mortality starting at 3-4 years and certainly should be considered end-of-life at 5-7+ years even if still working well. Drives written to once and stored away have the highest risk of data corruption due to not being read/written to on a regular basis. Rotate older working HD into low-risk use.
The implication of this is that you should not trust a new hard drive completely (really never completely!) until it has been working perfectly for several months.
Given the second law of thermodynamics, any and all current mfg. HD will, under perfect storage conditions tend themselves to depolarization and a point will be reached, even if the HD mechanism is perfect, that the ferromagnetic read/write surface of the platter inside the HD will entropy to the point of no viable return for data extraction. HD life varies, but barring mechanical failure, 3-8 years typically.
Hard drive failure and handling
The air cushion of air between the platter surface and the head is microscopic, as small as 3 nanometers, meaning bumps, jarring while in operation can cause head crash, scraping off magnetic particles causing internal havoc to the write surface and throwing particles thru the hard drive.
Hard drives are fragile in general, regardless, ... in specific while running hard drives are extremely fragile.

Some of the common reasons for hard drives to fail:
Infant mortality (due to mfg. defect / build tolerances)
Bad parking   (head impact)
Sudden impact   (hard drive jarred during operation, heads can bounce)
Electrical surge   (fries the controller board, possibly also causing heads to write the wrong data)
Bearing / Motor failure   (spindle bearings or motors wear during any and all use, eventually leading to HD failure)
Board failure   (controller board failure on bottom of HD)
Bad Sectors   (magnetic areas of the platter may become faulty)
