Samsung 850 PRO SSD anyone?

I wonder what the 512GB figures would be. The store didn't have the 1TB in stock, I decided to get the 512 which was actually pretty close in price with the 840 Pro. I'm super excited to get this in my machine.
The normal location for the OEM HDD is the lower position (lower when the mini is upright). So to install an SSD and keep the HD you have to take the main board and power supply out to get to the drive mounting bracket.
If your mini has the HD in the upper position I would just leave it there and install the SSD in the lower position. Much easier installation. Well, easier if you have the correct cable. OWC has the right cable to do that so you don't need to take everything apart just because of the cable.

It's cheaper on amazon.de, but macupgrade is the EU distributor for OWC I think.
Every source I have consulted with, including talking to an Apple 'genius' at the apple store confirmed you should ideally never clone a HDD to an SSD. Simply use time machine, format and install OSX from scratch on the new SSD and then load the time machine backup onto it.
Sorry for the ignorance, not sure but I'll check into how to make a clean install on a new empty SSD. But once I do that, and if I just load a time machine backup onto the drive, won't all the system files be copied too? Not sure if you know what I mean. But won't they over write everything I had just installed in my clean install?
Even if I install to the same type of drive I still use the method qcmacmini mentioned , cloning should really be used as a DR scenario. What I'm meaning is you regularly clone your setup in case of failure in addition to backups , then you restore the clone to the exact same setup. ( Preferably including hardware )
Once you are ready with the new machine with fresh OS you migrate the user account including data to the fresh setup.
Just finished my install and it flies!
480MBps write and 520MBps read with Blackmagic.
Was never prompted to restore as a fusion drive, simply booted it, formatted the drive, restarted and did an internet restore for OS X and then loaded the time machine backup from the spinner backup partition.
Took 40 mins thanks to the 95MBps read on the spinner and 200GB backup size, would have otherwise been much faster.
OWC kit is great, no problems whatsoever. Worked first go.

I ordered an 840 Evo and cancelled the order when I heard of the firmware issues, and I wanted a 1TB drive which the Crucial MX100 can't offer.
The pricing is a bit different here in Europe, but the difference between the 850 PRO and 840 Evo isn't the sequential read/write, they will be similar in that regard.
Tell me this, are the 2012 mini's are they 6GB SATA?
I have Samsung 840's in my 2010 Macbook pro and 2008 Macpro and the performance is great but they are only 3GB SATA in both cases afaik.
I have not read this whole thread but one OWC dead drive later I'll never touch anything but Samsung SSD, they make great electronics (Apple needs these guys both as supplier and competitor to be where they are ironically) and I have a trade supplier who has not had one single return on a Samsung SSD and they supply to multiple locations and the SSD's find themselves installed in a variety of computers.

I installed mine last weekend to my 2012 2.3 i7. Still got the stock drive running in there also, its my second mini, the first I used the OWC kit for the mini, this one I used the iFixit kit. the tools are better in the iFixit kit FYI.
So far so good TBH, I've got an 830 in a 2011 i5 an 840 Pro in my work laptop and now the 850 Pro , no complaints at all.
I've gone with Yosemite but if you really have to have TRIM, Mavericks might be better option. TBH I'm going to see how it runs for a while before I decide whether to reinstall 10.9.
Hope this helps and go for it!
I'm hearing so many mixed comments about this TRIM crap issue
. I've heard it's blown out of proportion and I can do without it on my 850Pro using Yosemite.I'm hearing so many mixed comments about this TRIM crap issue
Same here. I've got two Crucial M500s in a 2012 mini running Yosemite. I am going just let them run without TRIM. That way I do not have to worry about additional, user caused OS X issues.
The one running Yosemite has about 500GB used out of 960GB. The other 960GB SSD has about about 300GB filled. I am not going to worry about it.
Shouldn't be a factor in the 850 Pro. AFAIK the performance bug is specific to TLC NAND which the 840 Evo uses and not MLC which the Pro series use.

I thought this was a firmware bug, not a problem with TLC memory!?

The 850 Pro uses 32-layer 2-bit MLC 3D V-NAND and needs/uses therefore other firmware and algorithms.
Well you answered your own question. It's firmware relating to the TLC nand that's affected.
I may be wrong but I think all the models of drive also have different warranties.
The 850 Pro has 10 years as far as I am aware which for me was kind of a sweetener.

For me too. There is no such thing as 'future proofing' but my 850 PRO will eventually make it's way into my Thunderbolt SATA III enclosure, and will be my backup drive with warranty for many years to come

Agreed, I'm too cautious for my own good some times! When the larger model prices take a dip, I'll be picking up number 2 I think.
Also the warranties compared across models for those who are interested:

OK, we've got a deal for you. Bring back the down thumbs and we'll stop bickering. A deal?
