#145575 — New iMac belated upgrade

My new iMac is two weeks old, and I ordered it without an SSD as I thought 
the iMac cost enough as it was. An SSD was an extra £200, from memory. A 
silly decision.
So now I want to enquire if it would be possible to fit an SSD now?

I see that on Amazon I can buy an external Samsung TS 500 GB USB 3.1 external 
solid state drive for £83.79, lots cheaper than the Apple installed internal 
SSD.

Would this work OK? I do need it to speed up the Mac as it is painfully slow 
in comparison with the W10 machine I’ve just ditched.

My iMac is a 3.6 GHz quad core, 1TB HD, Retina 4K

I would be grateful for any advice.
Thank you, Peter

I buy my SSDs from Crucial: https://uk.crucial.com/catalog/ssd

Historically Macs used to need custom firmware in their hard disks - I 
don't know whether that is still true ...

Others will tell you how to get the Mac apart.

Being a Mac, you should be able to install the OS onto the SSD via 
download or a restore from Time Machine, rather than the horrible "clone 
disk" process that is forced on Windows users.

that has never been true.

macs have *always* worked with industry standard hard drives.

cloning works quite well on a mac.

The discussion at 
<https://superuser.com/questions/114577/what-makes-an-apple-hard-drive-special> 
would suggest otherwise, specifically with regard to temperature sensing.

Also: <https://en.wikipedia.org/wiki/Apple_HD_SC_Setup> says "The 
version of Apple HD SC Setup that shipped with the classic Mac OS was 
only able to manipulate hard disks that featured Apple ROMs." although a 
third-party patch did allow a work-around.

My point being that getting a Windows OS on a virgin disk us usually a 
pain and requires the appropriate (set of) disks from the manufacturer, 
which will be complete with all the necessary drivers.  If the virgin 
disk is simple an upgrade (as with HDD to SSD) then the clone process 
usually works and is much simpler.

By contrast I'm told that one can download an Apple OS onto a virgin 
disk in one easy step (which might of course take several hours); so 
this obviates the need to clone.  i've no personal experience of this.

there can be an issue with the temp sensor but there are third party
solutions for that. it's also specific to certain models.

that was a limitation of that particular app, not the hard drive.

third party hard drives worked quite well and were bundled with a
formatting utility, which could also be purchased separately. fwb tools
was one of the more common formatting tools. i don't remember the
others.

that used to be the case, but it's no longer true. download windows 10
from microsoft and install, even from a usb stick.

however, migrating from an existing windows system to a new install is
going to be a pain.

apple's internet recovery is rather amazing.

Ah, but you still need a working machine with an internet connection. 
Not very helpful if your only machine has just suffered a hard disk 
failure!  And the OS is probably the least of your worries.  You then 
need the manufacturer-specific drivers for your hardware.  Without them 
you may well not have an Ethernet connection, and you certainly won't 
have the right display.  Some power management things might also be 
missing.

I'm sure this is a deliberate design decision by M$.

Years ago (about 1984) I used to tinker with RT-11 on DEC LSI-11s and 
one could write a driver for a new disk controller, use it to format the 
new disk, copy the boot block and all the files to the new disk; then 
boot from it.  Writing the driver might have taken a few days, but once 
written copying the system to a new disk was simply two commands.

I've never understood why M$ could not have done the same, right from 
MS-DOS onwards.

Presumably the trick is that all Apple hardware (perhaps at least since 
OS-X) has a functional Ethernet connection, TCP/IP stack, and simple web 
browser built-in; so works even if there is no hard disk present.

these days, most people have more than one computer. if not, they know
someone else who can download it for them.

there's a base level functionality at which point you can get
additional drivers if needed.

it's also not an issue for cloning an hd/ssd since the rest of the
hardware doesn't change.

probably not. they just never bothered to even try.

classic mac os could be copied simply by dragging the system folder to
a new hard drive. mac os x needs a clone utility.

because they don't care. 'good enough' is all that matters.

it's not a trick.

internet recovery is an intentional design decision for the situation
where the user has a non-bootable computer and no way to get the os.

it appeared about the same time when mac os was no longer available on
a dvd.

there is no web browser, however, a hd/ssd is required. otherwise there
would be nowhere to install mac os.

Is there a user interface so you can tell it where to get the OS from? 
Or is it hard-coded into the firmware?

it's currently a bit convoluted, but you can boot from internal hd/ssd,
external volume, net boot or internet recovery. the ui will change with
apple silicon.

internet recovery will download a new os from apple. downloading from
anywhere else is both illegal and an incredibly bad idea.

If Apple did something like that there would be larger problems to worry about
than you having to make a USB installer using another computer instead of
using Internet Recovery.

Eh? You're suggesting Apple would sabotage it's own 'last ditch' rescue
operating system installer.

Are you mistaking them for Sony or Google, perhaps?

Three key combos which do different things.

Yep we can add an SSD later, but we'd use SATA rather than the faster
Apple blades, however can supply & fit 1TB Crucial for eg for around
£220 (vs the £200 for the Apple PCIe 256gb SSD or £400 for the 1TB).
It's not an install I'd recommend as a DIY install. 

Being so new though, I'd echo others that I'd be tempted to return if
you can and swap for one with an Apple SSD from the get go.

Yeah, having replaced the drive in my iMac twice now (well out of 
warranty, one to upgrade to a 3TB HDD, and the currently installed 512GB 
Crucial SSD) I agree too, it's not a job for the faint hearted, or a DIY 
job on a brand new machine.

Crucial is good but not among the cheapest brand...

About the custom firmware. Yes, but I think this now is historically. 
But to be sure do use any harddisk/SSD with OHCI ver. higher than 1,8.

I was about to make a not good decision bying a new harddisk for my 
MacBook Pro 2007/08 - a 1tb HGST TravelStar 7200rpm/64mb cache, - until 
I discovered - by luck - that this disk only has OHCI v.1,6 and was made 
for some specific ThinkPad models and therefore only can be used in 
MacBooks / MacBook Pros 2006 or older...Ups!

Cheers, Erik Richard

as the saying goes, you get what you pay for.

nonsense. it will work perfectly fine, however, an ssd would be much
better.

OHCI can't the term you're thinking of, as it's only for USB (1.1 at that).
I'd have expected AHCI, which is for SATA, but that only goes to 1.3 (and
that's from 2010). What are you describing?
