Default Samsung 840 vs Samsung 840 pro

I am considering getting a samsung 840 and am wondering if someone can clarify the diffrence between the 840 and the 840 pro? The standard 840 has a warranty 36 months for where as the 840 pro warranty is for 60 months.

What is the physical difference between the two and why has one got a longer warranty than the other? I am thinking of getting the pro because of the 5 year warranty.

840 Pro is faster but you won't notice much difference in real life usage. 840 Pro also uses more durable NAND but unless you write a lot of info to your drive, you probably won't notice the difference as they will both be obsolete in a decade anyway. So I wouldn't pay that much of a premium for the 840 Pro. Then again, I don't like TLC so I would not get the 840, either... especially because both are new drives, and I hesitate to recommend new drives simply because there could be some unknown firmware or controller issue that becomes known only with time.

The 840 is TLC and the pro is MLC. The 840 pro is the successor to the 830 whereas the 830 is a new type of drive, the only TLC SSD on the market.

I was actually researcing the same thing this weekend... I probably would go with the 840Pro.

I've also been looking at the differences between the Plextor M5S and M5Pro... I would probably take the M5S over the standard 840...

Clarification: I think he meant he does not like the lower quality TLC NAND so he would get the PRO480 instead- and not the normal 840.

Grammar is a bit wrong.

I also think he meant 840 is the new version. "830" is the older drive and "840" is the newer.

Old drive was 830. New drives are 840 and 840PRO. Pro has better Nand inside and a bit faster. Both are fast and good SSD's.

If you look at my sentence structure it's clear I meant I would NOT get the 840 due to the TLC. But thanks for pointing out the error. Fixed.

The difference is insignificant unless you're putting the drives under extreme conditions and testing. What the price difference? You should probably go for for 840pro purely because of the warranty. Warranty of 2 more years! That's a strong reason to choose it over 840.

Yep. 840 pro more durable, has notably faster writes. 830 is better than regular 840 in some ways. I went from vertex4 to 840 for the boost in reads, but will be adding at least two 840 pros for premiere and solidworks dataset drives (along with 4 wd blacks in raid, hope to add two more soon and move my last two 1tb blacks into my nas).

I wouldn't lose any sleep if I bought a normal 840. Using TLC most likely won't amount to much of a difference to the end user unless they want to use the system for two decades.

One note - if comparing read / write speed as part of this decision, keep in mind that (at least for the 840 Pro) there's a significant difference between the 128 and 256GB versions.

Hi, everyone!
Would be nice to hear your opinion, is Samsung 840 Pro good for using in iMac 27 (2011) considering it's controller and architecture? Would you choose it over Intel 520 (sandforce2281 = TRIM issue, + OS X with no TRIM by default for non-Apple SSD's).

It is not all that big of a difference:

Sequential read: 530 MB/s on 128GB, 540 on 256GB
Sequential write: 390 MB/s on 128GB, 520 on 256GB
Random read iops: 97k on 128GB, 100k on 256GB
Random write iops: 90k on 128GB, 90k on 256GB

So the only thing of significance is the sequential writes, which are 33% less on the 128GB drive,

Just picked up a 128GB today, cloning to it now

Agreed. I'm fine w/ it too, and I have the 128GB myself. Just wanted to mention it, for some people 33% is a huge deal especially when paying a premium.
