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.

EVO is plenty fast. We've got both EVOs and 840 Pros in an z820 and I can definitely say the Pro's are not worth the 2x the price upgrade. Just get a 1TB EVO adn it will be smoking fast.

^ Concur, I just put a 500 Gig EVO in my new laptop - The higher end ones are just not cost effective. The Laptop only has space for one drive, hence the 500 gig.

Only cavet is longevity. They will not last as long as the higher end ones and TRUE reliability/lifespan as tested by users is another couple of years. Manuf test are NOT real life.

I have about 13 SSDs and Not one failure. Oldest SSD is a Intel G1 and G2.
Newer ones, Have Crucial M4's 128 gig/256 gig, Samsung 830's both 128 & 256 gig, and Samsung pro 128 gig/256 gig.

As to performance, there is only a nickels worth of difference. Might look at the crucial M500 (newer 550 priced closer to the 840 pro.

Recommend you not fill drive past the 75% mark to maximize longevity.

I recently purchased a new Samsung 840 Evo 500GB, (Newegg for $234. On a ‘special sale), to replace my Plextor PX-256 M5Pro. My computer now contains 4 internal drives.

The Samsung SSD carries the O/S and several other ‘key’ programs such as Adobe Acrobat X Pro, CS 6 Extended, MS Office 2010 and a few others, (via Junction Points), which in total, take up about 140GB of the usable 465GB.

The Plextor carries one massive program; MS FSX and only the Root folder at that. At 154GB, FSX takes up two thirds of the drive’s usable space, which is 238GB.

Then I have two Seagate Barracuda, 1TB HDDs of which one that plays a direct support role to the Samsung O/S drive.

The other HDD handles remaining flight sim add-on programs that perform better when they’re not loaded on the same drive as the main FSX program, (i.e. MegasceneryEarth programs and the like).

(I thought I’d detail my drive layout just in case the info was comparable and played a part in your own usage).

I used HD Tune Pro, (just a few weeks ago, when I bought/installed the Samsung), and found that the Samsung 840 Evo was considerably slower by over 55% than the Plextor for any read/write/transfer operations of 512bytes to 64kb.

(I couldn't seem to get the info to space out correctly in this editor but it's not too hard to see the line-up)
Random Access test result Examples:
The Plextor:
Transfer size ops/sec avg access time max access time avg speed
512 bytes: 21443 IOPS 0.046 ms 0.165 ms 10.470 MB/s
4 KB 16879 IOPS 0.059 ms 0.497 ms 65.934 MB/s
64 KB 3430 IOPS 0.291 ms 0.717 ms 214.413 MB/s

The Samsung:
512 bytes 7935 IOPS 0.126 ms 0.268 ms 3.875 MB/s
4 KB 7839 IOPS 0.127 ms 0.578 ms 30.624 MB/s
64 KB 3569 IOPS 0.280 ms 0.661 ms 223.068 MB/s


However, when the transfer sizes get to 1 MB or bigger and in Random transfer sizes, the tide changes drastically and it’s the Samsung that begins blowing the Plextor out of the water.

I’ll only list the results for the Random Transfer here but take my word for it when I say that the Samsung was twice as fast as the Plextor from the 1 MB transfer size on up.

The Plextor:
Random 503 IOPS 1.986 ms 4.378 ms 255.365 MB/s

The Samsung:
Random 784 IOPS 1.274 ms 2.534 ms 398.222 MB/s

If I understand “Retiredchief’s” post correctly, it would seem that I might not have the Samsung playing the best part in my present drive setup. But unless he, or someone else knows what the average size is in the data FSX deals with in comparison to the average size of the data the O/S is dealing with at the same time, I can’t be sure I have the two SSD’s in their best roles.

Of course, I ran Benchmark and File Benchmark tests as well as others and the results were similar. I’m guessing that you’ve already decided and bought the drive you wanted. I don’t know if the difference in the capacity between the Plextor and the Samsung had anything to do with the test results I got. Maybe someone else can shed some light on that.

It would be interesting to see what the same HD Tune Pro, “Random Test”, test results for the 840 Pro are to compare them to the Evo tests I did. If you do happen to get the Pro version, maybe you can run that test with the freeware version of HD Tune and post it here. I’d be interested in seeing what the results showed.
Thanks, Rich

I have both Samsung 840 EVO and 840 PRO. Could say no perceptive difference in real life.
After saw Tom'sHardware bechmarks I think 840 PRO is faster. I would suggest 840 PRO.
Just because Samsung 840 PRO has more GigaBytes for the money! Both are really fast!

[]'s!

Thread dig, well sort of..
seems this is the place to ask as you guys seem to know more than me...
The difference between a PRO 256GB, an EVO 250GB and a 1TB 5400RPM old school HDD?

Yes I'm using a 5400RPM old school HDD...lols

Cheers..

Samsung evo and pro are both ssd, solid-state drives, no spindle like in the 1tb 5400 rpm. Ssd's are generally faster. Pro i think has power loss protection and longer warranty than evo.

Power loss protection? Should I consider this as I'll be using it in a laptop with limited power supplied?

I've had the 840 Pro 256GB in my desktop since before the EVO came out. I love it. I suspect it will long outlast my desktop.

I just bought an 840 EVO 250GB for my son's desktop yesterday... but waiting for the 6GB SATAIII cord to arrive today to finalize installation.

It was ~$70 price difference with the EVO being cheaper. My son is still 12. I just need to get his [6 month old] computer to last 4-5 more years to get him to college where I know he will need whatever the latest and greatest is (tablets? Google Glasses?).

I've got faith the EVO can get him/me there.
He also has a 1TB HDD for data (I have a 2TB HDD for data)

If the price difference is just a few bucks i would go with the pro. I have been using evo for almost a year now and i can say it's yet to disappoint me. No hang up, no bsod, nothing.

Cool. Either of them is an excellent choice anyways. Enjoy

So the EVO is in fact, faster, given that you have a surplus of RAM to burn?

I've seen new Samsung 840 Evo 500GB SSDs on sale for $200. I have three and also two OCZ 480s. The OCZs cost more but do not seem as mase as the Samsung 840 Evo 500GB.

When I got my 750GB EVO on Amazon, it was at around $380, maybe $390. It was right around Christmas time (a gift for myself....) and I was in the middle of upgrading my machine to a more enthusiast build.

Anyway, alongside with that I spent $210 at the beginning of that month for a 250GB PRO SSD. So, I put my OS on the PRO SSD and I put all my Steam games on the EVO.

However, I believe you could only use the RAPID technology thingo on one of the SSD's at a time. I think it was also like a recent update at the time that made that feature work on the PRO as well, so it seemed rather sexy, so that's what I did.

Honestly, after months of use, I haven't noticed a difference between either. My logic for putting RAPID mode on the PRO (with my OS on it) was to possibly improve boot time.


Right now, there is a sale on newegg that puts the 1TB EVO SSD at $460, but if you are subscribed to the site you can get a promo code today only that puts that down another 70 dollars, which makes it worth exactly as much as the 750 GB EVO SSD that I bought last year. (Also sort of makes me jealous, hehe)

Didn't notice any problems at all, but just used the update to make sure none arise :)

I ordered a new SSD drive for a computer I am building. It is the Crucial 960 GB. At the bottom of this page from this link http://www.crucial.com/usa/en/storage-ssd-m500 you will see a chart for the different SSD drive specs that they offer. The MTBF is 1.2 million hours. This is a lot of years! As for writing lifespan, these drives are 72TB. This means if the PC wrote 40GB per day it would take 5 years to wear out the drive. I don't see the average user even for an office or regular business type working job 24/7 would meet this quantity of file writes in a 5 year period.

For someone who will be downloading a lot of movies every day and doing a lot of writes, it is suggested to use an SSD for holding the OS, program files, and operations that require moderate disk writing. For large scale disk writing and high traffic volumes that will use a lot of writing a regular fast hard drive would be the right choice. There are now the new hybrid drives. These are interesting for speed, use SSD caching, and use magnetic media for the large bulk writing.
