DISCLOSURE: I may not have read the preceding 2650 posts.

2010 unibody Macbook, 3GBps.

Is there any benefit to buying a SATA II SSD rather than a SATA III?

Did I read somewhere, some time, about some SATA III in some Mac with a SATA II bus only functioning at 1.5GBps, or something?

It's mainly an issue with Macs that use a certain SATA II controller (can't recall what it's called -I have it in one of my late 09' Mac Mini's), & that controller's fine with some make/model SSD's, it's usually more of an issue with Sandforce-based SSD's IIRC.

Do some research (not just here; rather some Googling) on your hw, you'll find out quickly if you're in the clear or not.

Have established that:

* SATA IIs are getting scarce, and hence are no cheaper than SATA IIIs

* Samsung isn't Sandforce

* the empty 840 Evo box sitting on the desk RIGHT UNDER MY NOSE, which I just picked up to check the part number, has SATA 6Gb/s compatible with 3Gb/s written on the side of the box.

So another 250GB 840 Evo it is, then.

See, that wasn't so hard...
If you want uber perf. above all else Samsung Evo isn't it (nor is the other Samsung iterations).*
But bang/$ it's at the top, as is Micron/Crucial's M500, & to a lesser extent (for now) M550.

*but you prolly don't want/need that if the disk won't ever be used in a newer machine/env

Nah, I value reliability/familiarity over shaving a second off my boot time, or winning at benchmark tests. When I'm done finally with the MacBook I'm sure the SSD can find a home in an enclosure, while my Mac Mini Pro (the 'Early 2018' revision) will have an 8TB SATA V SSD running at 48Gb/s.

At least one of the current perf. leaders is tier-1, there's absolute reliability/familiarity*, but, your logic sounds fine for your circumstances.

*not the blazing hot stardom/fandom Samsung enjoys, but tier-1 NAND OEM/ODM nonetheless

This all sounds a bit Ars Technica to me!

What qualifies an SSD as 'Tier 1'? It can't be much more than the warranty length and faith placed upon it by the manufacturer, surely?

I must admit it was MacRumors that pointed me in the direction of the 840 Evo, but I've read very few bad things about it elsewhere.

Micron/Crucial, Samsung, Sandisk, Intel.

Are the four tier-1 NAND fabs, they are (more-or-less) the source of all NAND tech for all the other brands.

Ah, by 'Tier 1' I thought – with the aid of Google – you meant 'suitable for use in mission-critical applications'.

That's what happens when I 'do some research', see?

So I went ahead and splurged on a Samsung EVO 840 750GB SSD for my early 2011 MBP. It was $399 on Amazon.com. I'll be upgrading from my 500GB 7200rpm HDD. Will there be a noticeable difference in speed and performance?

Yes - although the 7200rpm drives are speedy, the SSD will be even faster. If I remember correctly, at least with the Samsung drives, the higher the capacity, the higher the read/write speeds - it's not much, but I think the 500/750GB drives are a tad faster than the 250GB one. Still, it should be a nice addition to your computer!

I know both are used quite a bit on here - lots of 840 Evos in use and seem to be holding up well (I know one poster had his fail and was going to let us know about the warranty process), but I've also heard about Crucial models fail here and there - it's still a really small percentage of all sold and both are popular and arguably solid choices.

I really hope the one I just ordered does not fail on me. I don't have that kind of money to throw around. if it does I'll just go back to an HDD. But I've heard overall great reviews for the Samsung EVO so I'm trusting those to be reliable.
