Samsung EVO 840/850 safe to use in OS X?

Just wondering if the Samsung EVO 840 & 850 drives are compatible with Mavericks / Yosemite?

Thanks

Yes they work great I use it in all my Macs that have replaceable HD's. Great performance for $250.

I run a 256 gig Samsung Evo 840 in my iMac with Trim enabler. I'm staying with Mavericks for now. Works great.

Using an EVO 840 in a 2012 Mac Pro at work. So far no issues.

If I had do overs, I would do it gain in a heart beat...big improvement

You can use them, however you will need to use something like Trim Enabler (»www.cindori.org/trim-ena ··· osemite/) to prevent it from slowing down over time.

To me this is a little too hacky and won't necessarily work with new revisions of OS X. Thus, I generally recommend OWC (»eshop.macsales.com/shop/SSD/OWC) drives for upgrading older Macs to an SSD. They will not slow down like the Samsung will.

Hope this helps!

Without Trim enabled, the most slowdown you will see on an SSD is a whopping 9%. It will still be on the order of 2-3x faster than spinning rust.

Going to be honest this to me says more that its OSX that is terribly flawed. If has no ability to set trim in the OS without a third party app it has a problem.

That is by design. The third party app just changes a setting internally that OSX refuses to change unless you're using a Steve Jobs(TM) SSD. The OS can do trim just fine

What is it about OWC drives that keeps them from slowing down without Trim?

Nothing special about the OWC drives themselves. They just happen to use a SandForce controller to manage how data is written internally on the flash storage. It uses much more sophisticated algorithms and techniques to reduce and even the wear on the flash storage (which is sort of what TRIM is supposed to do).

In fact, there was actually an issue with enabling TRIM and using a SandForce-based SSD at the same time:
»www.anandtech.com/show/6 ··· b-review

I think that's long been fixed, though. But OWC still recommends not manually enabling TRIM with their SSDs (although the article is from 2011). More info on the topic here:
»blog.macsales.com/11051- ··· e-answer

There are other, cheaper SSDs that also use the SandForce controllers - those companies' marketing departments just aren't as good as OWC's. The bargain basement SSDs rarely use these more complex controllers and definitely do require TRIM to prevent slowdowns.

Sounds like OWC is a good choice for Macs and Playstations. I'd prefer not to use a hack to enable Trim. I'm thinking about replacing my Samsung SSD with a OWC SSD so I feel comfortable upgrading to Yosemite. I'm thinking about replacing the Crucial SSD in my Playstation 3 with OWC too.

You may want to look more into your particular models first. Some Samsung and Crucial SSDs use the same SandForce controllers that OWC use. So there'd be no reason to switch SSDs.

There's also some rumblings about SandForce controllers having bugs that lead to complete data loss and full-disk encryption (like FileVault) fooling their garbage collection algorithms into being useless, although I have not seen this on my SSDs that use the controllers:
»communities.intel.com/th ··· ad/33953
»blog.erratasec.com/2012/ ··· ers.html

I'm sure you could find similar post about other SSD controllers, too, so take those with a grain of salt.

I bought an 840 EVO and so far I'm just using it as a SuperDuper clone for on-the-road use. My MBP only has USB2, so I use FW800 to an OWC external FW enclosure. My first clone of my 750GB 7200rpm hybrid drive to the EVO took just over 5 hours, which is about 40% of the time it takes to clone to a FW WD Black 7200 magnetic drive.

Samsung uses their own I thought. Or maybe that is just the pro models.
