Samsung 850 PRO SSD anyone?

I F-EN HATE OWC for those fast tutorials. I ripped out the IR sensor socket from the actual logic board. The wires are still intact, but now it's just hanging there. Anyone know exactly what that's for, other than for the remote control and the actual light on the mac?

Other than that, I got the SSD and my old HDD (not the factory one that came with the mini) into the machine, and everything looks like it's working fine. Just don't know why people said the HDD should be in the upper bay and the SSD in the lower. I accidentally did it the other way around and everything seems to work fine after I changed STARTUP disc to my SSD.

I formatted the SSD and installed Mavericks with a bootable USB. Now is the pain in the butt part when I'm copying everything over from the HDD (my HDD was using Yosemite instead and I didn't want to use that with this SSD cause of TRIM issues.)

Not sure if you're being facetious or not. Personally I love OWC's tutorials. I've used them on several Mac models. It still scares the hell out of me to open a mini. I've been in my 2.3 i7 three times and my one-month old 2.6 i6 twice, still shivering. My formula; set up MBP with OWC tutorial, rip mini apart, make sure it works when done, drink a glass of red wine.

I was also a bit paranoid, these are very delicate computers, the only thing that annoyed me about OWC tutorials is that they clearly took like 100 goes at filming each section. Putting the stock HDD back takes a bit of wrestling with the power supply cables but in the video you can see the cables are really stressed and mangled so they sit over to the side and out of the way.
 
So they run through the tutorial 100 miles per hour, then they offer you to buy a fix it kit for the IR sensor. It's as if they did it on purpose. I tore out that damn socket so easily, and I'm not ready to dish out $400 for a replacement logic board. I just wanna know once and for all what that sensor exactly does.
 
The Tech Report web site has an interesting article on the endurance of SSD drives. The Samsung 840 pro and the Kingston Hyper x drives have both survived two petabytes of writes so far. Tech Reports it would take the average user a thousand years to reach that total.

To be fair they tested several other drives that failed at 1.1 and 1.2 petabytes.
Slowdowns have been relatively minor.

From the Tech Report web site:

The results of our experiment do, however, point to some more general conclusions about SSDs as a whole. Although only two drives made it to 2PB, all six wrote hundreds of terabytes without issue, vastly exceeding their official endurance specifications. More importantly, the drives all survived far more writes than most users are likely to generate. Typical consumers shouldn't worry about exceeding the endurance of modern SSDs.
 
Can't believe I waited this long to get an SSD.

I got everything up and running, booting off the 850 with Yosemite, TRIM Enabler is on. Second drive is an 7200.. Everything is flying. I love it. :eek:

All that's left is finding out what the consequences of that IR Sensor socket I accidentally ripped out will be. :(

It's just the IR sensor and the LED power light--nothing else.

Some have had success carefully gluing the connector back in place. Others have had it soldered by someone who can do that kind of work. Still others have made it worse trying to fix it themselves, or have someone else attempt the fix.

So it might be best to just leave it. There are other solutions for remotes anyway, should you need that functionality.

I don't use a remote and I have it set up in a place where I can't even really see it, so the light was useless anyway. Glad to know it's nothing more serious than that. Thanks by the way.

Trim enabler works in Mavericks and Yosemite, I would just use that and not worry too much.

Maybe disable trim before doing an OS X update when 10.10.1 comes out to be safe, but by then we should know if this is necessary based on feedback from the beta testers.

No need for Trim on modern SSDs; they run their own garbage collection. The best defence against a slow down, irrespective of Trim or not, is to have at least 20-25% free space on the SSD.

This is not true. Enough read and write operations and your drive looks full to the controller. Every Anandtech review does a TRIM test and even the 850 Pro, the current king of SATA SSDs needs it.

This is the key point. Most people won't. [esp in SSDs over 500GB]

I really wish people would stop equating TRIM with garbage collection. They are not the same thing. It's like saying your house doesn't need to be connected to a sewer system since it has garbage collection. ;)

I understand the difference and have read extensively on the issues. Doesn't make me an expert, but I do also have 'real world' experience having used a number of SSDs since early 2009.

Bottom line is SSDs are increasingly more sophisticated out of the box. Early SSDs degraded in performance relatively quickly in a measurable way. Recent/current SSDs don't (Crucial and Samsung esp).

Technically, properly supported/implemented TRIM is best, but in real world everyday average use it is just not necessary. Performance does NOT degrade in any measurable way. [Note, this is for the average user - video editors etc are a different case.]

Something else to consider is the upgrade cycle. As SSDs become increasingly cheaper and in higher capacities, users (with upgradeable machines) will often swap out their SSDs long before theoretical ceilings are hit.;)

And tools like PartedMagic can also easily restore SSDs to essentially full performance.

I'll be picking up a 1TB SSD from Samsung within the next couple of weeks. It will be paired with my 2012 Mac mini and it's current 256GB 850 Pro that I installed last night. The thing just flies...

For my 2nd and final drive for the mac mini...I'm still deciding on whether or not to pony up and just get another 850 Pro for the 1TB or drop down to the 850 EVO (or possibly even the 840 EVO)...

The 840e should drop a bit when the 850e ships. A week ago they were on sale for 380 or so. No need for the newest as a file container when you have the system on a pro IMO.
Either way, sounds like a sweet drive setup.

Exactly, I have my system running on an 850 Pro but was waiting for the 850 Evo to come out before buying the 840 Evo for my external LaCie Rugged TB.

I did not see it mentioned in the article, but I was thinking perhaps the 840 EVO would go away shortly once the new 850 EVO gets ramped up and the price drops a bit. It doesn't make sense to me to have that many SSDs out there at the same or very close pricepoints.

If it's anything like the 30/40 transition, there will be plenty in stock for months. Many will be waiting too see if there's a huge drop in price once the 50 fills the channel but I think you're right about price. They'll be close, like 30 bucks. Remember, it took a while for the 40 to get going and drop below 550. Seems like the 1tb model was rare the first 4-5 months. I also remember people on this board and elsewhere not trusting the 40 for months. Remember all the comments about sticking with the 30?
That was then ;)

Original retail on the 1tb 840 was 649?
Starting retail on the 850 is 499

I bought direct from OWC in the US but you will probably get stung with import taxes like I did.

That's because you chose DHL as the carrier.

With DHL, UPS, Fedex, USPS Express International, you have 100% chance to pay the duties + taxes + the carrier outrageous brokerage fees in Europe.

If you choose USPS Priority or First Class International, you are more likely to dodge the bullet but then the shipping is slower.

My last package from OWC worth $36 + cheapest shipping fees $3 came home in France in 20 days during rush Christmas period without any additional duties/taxes/fees.

Learnt my lesson and picked USPS the next order and dodged the taxes! In saying that PostNL is probably more efficient at picking up taxes even through the post than the French system ;)
