Hey folks,

I've been leaning towards the Samsung 840 Pro 256GB, but I just wanted to ask everyone - In your opinion, what's the "best" and most reliable (don't want it burning out like my last OCZ) SSD for the money.

Thanks,
R

What's the fundamental difference between the EVO and the PRO? Will I notice the difference in speed? I'm leaning towards the PRO because of the inherent 5 year warranty - as opposed to the 3.

Yes,
In SSD's you have a lot of memory chips, (bundles of 256kb) that are laid out onto larger ships, and then onto the boards. Since you are changing the state of the little pieces, eventually they will wear out.

So, in regards to longevity, the pro's are better by about a factor of two.

If I remember correctly the pro was rated for atleast 500 rewrite cycle which is a lot more than SSD's used to be.

For a 120gb SSD, it would last for 60tb of rewritten data. At that point I figure that most modern SSD's will become technologically aged before they wear out.

However I would suggest the 840 pro, I have one in my laptop and I love it for the speed it boots in

Flash memory can be read many times without any detrimental effects. Unfortunately the same cant be said for writes.
The Evo uses triple level memory cells and can be erased* and written to 1000 times (roughly)
The Pro uses MLC cells (dual layer) and can be written to about 3000 times.

* flash memory must be erased before it can be written to unlike an HDD which can simply overwrite existing data.

I had a Samsung 840 fail on me, and replaced it with a Plextor M5 Pro.

It's working fine, and I'd buy another one if given the choice again.

I'm not sure that "most reliable" is the same as fastest or most popular. One thing that I always wonder about is how thoroughly the firmware gets tested before shipping.

Unless they have similar failure rates as others, but can take the warranty hit (from those rare people who keep the receipts for up to 5 years and can be bothered to claim) because they sell a lot more by giving them a 5 year warranty and hence make more money. Or it could be a marketing scheme to get a strong foothold in the market. They are a big company, so can afford schemes like this, that initially might hurt, but give returns in the long run.

Korean car makers do a similar thing with their warranties, and it's paying massive dividends as sales shoot up as people think they must be ultra reliable.

All I'm saying is, there can be other factors involved.

Get the PRO version. the EVO has problems with older programs taking longer and longer to load.
