Which of the two is better and why?

I plan on buying a 250GB SSD off eBay

I am wondering if I should choose the Samsung 840 Pro 250GB or Samsung 840 Evo 250gb. Both are available for close to the same price.

I will be using it on my laptop. I download a lot of movies, do photoshop, play games, etc.

Thanks

1) 840 Pro has higher benchmarks - NO BIGGY as in real life You will not see a difference in day-2-day performance.

2) 840 EVO uses 19nm TLC, 840 Pro use MLC and has a higher write cycles rating - No a bigg issue as under normal usage the your still looking at 10+ years of use.

3) Power consumption very close for EVO and Pro ( about the best for SSDs)
... Power consumption really only an issue for laptops.

4) Pro = 6 gigs more space - again depending on space required probably not a biggy.

To say that I really like the EVO is an understatement. If Samsung can keep quantities of the 840 EVO flowing, and keep prices at or below its MSRP, it'll be a real winner and probably my pick for best mainstream SSD.

1. MLC = Multi-Level Cell, which, by definition, includes TLC (Triple-Level Cell). Not a big help there.
2. Price has nothing to do with quality. The mentality of "cheaper must be worse" is a prejudiced buyer's bias.
3. "Better" it depends on what is your definition of "better": For a price-conscious person, it's value (bang for buck); for a wall street broker, it has to be fanciest, braggiest, most expensive gizmo no matter if it breaks in a week or two.
4. 16, 40 years life expectancy is hogwash, given that the average user upgrades (throws) his/her whole computer setup away in 3-5 years anyways. Haven't seen a dude these days grabbing onto a 1998 computer device for any practical purposes.

My advice (aka solution): If you already narrowed it down to either 840 Evo or 840 Pro (no other brands or models of SSD to consider), just get the one that's on sale from a reputable seller. They both will fulfill your use of Photoshop and gaming.

I work in many servers and systems. I work in support for broadcast media at a major TV network. We are using Crucial, Kingston, and some Samsung. As for failures there are very few. The odds are when employing thousands of these drives in a large facility there will be a percentage of failures. I would say during the first year in would be less than 1%. I believe despite of all the reviews I read these drives are all about equal. Where I work they go for the combination of past reliability and cost. Speed with SSD drives is not an issue and is difficult to be concerned about. The ones I mentioned are all good.

At home I am building my second super micro system. I am using eight processor cores at 4 gHz. I have been using the Crucial SSD drives with excellent results. I use the 960 GB ones. For large data writes and reads I use the Seagate hybrid drives.

I tried the hybrid drive for the boot drive. It is actually about 80% as fast most of the time at the SSD for less than 1/2 the cost and have greater capacity for the cost.


This is my personal experience.

I'm really disappointed in my results… What am I doing wrong here?

The really separate benchmark program screens display the result after aftersensation to the above Magician app.

Thanks,

Have you looked at the Kingston and Crucial? I work in IT systems support. With these two we had very little failures or problems. In my personal PC at home I have the Crucial 960 GB. I spoke to dealers who sell in volume. They also had good customer response from these.

The Samsung from the reviews I've read is a top quality drive. I guess it's a matter of preference based on personal experience. Any one of these should work well. In about four years or so you'd probably be changing your PC anyways. Because of the tech advancements and age of the PC you would be buying all new anyways.

My numbers were all over the place too so I ended up using a utility called HD Tach to record my speed and stuck with that. I found the most unreliable software to measure speed was actually the samsung magician software. Each time a different reading and readings all over the scale. I uninstalled their software and just did what I have to do in windows like disable hibernation, disable indexing and disabling the page file and my 840 evo runs just fine.

I have brought an 840 EVO recently, yes they have migration software as well. Having said that, if you are using Windows, just shrink the partition, defrag and use Clonezilla. Though the software caught a few settings that Windows did not adjust (you can probably download it from Samsung as well).

If price doesnt matter, get the 850 Pro... or better yet, get 2 and set them as a Raid 0 config.

I have had the 256GB Evo for well over a year and it is fast. Make sure your laptop supports SATA 6 or you can kiss all that performance from any of them goodbye.

What about the speed of SSD drives already being faster than the sata interface? Does it make a difference that a normal user would see (eg not a video editor and not on a server).

Isn't M.2 supposed to answer the conundrum of the sata being way slower than many ssd drives rated speeds?
