Edde · *Last edited by Edde; 04-13-2012 at 03:16. Reason: ading more information*

Hello everyone. I am with a terrible doubt.
I am building and setting up a workstation for me and I need reliability and durability. I want to buy intel SSD. Is available At the store in my townthe 510 series and 520-series. I read some reviews on the Internet about both ones ,and some of the speak well about the 510 series and speak the other reviews speak very well about 520 series. I'm not interested in 3-10% difference in speed. The 510 was I had in mind last year. Now I have the 520 series as another option. I was wondering the possibility to buy the 520 series. What does the forum think about this? which the experiences and stories here? It is better even SandForce insted the Marvell controller? Please help me. I want to buy intel ssd which is less susceptible to errors.

Thank in advance

Edde

PS: By the way, my profile here at Guru3d is my old computer, the new one works with sata III 6gigas.

What is the price difference between the two?

Hello Automaticman, thank you for your reply.

almost the same price here, the 510 is just slightly more expensive.
The price does not matter, what I want is quality and reliability between these two. Wich one is the best? I am not talking about speed and etc. I am talking about a good hardware and no bugs.

Thank you

in our currency cost:

510 series 120 gigas R$ 849,00
520 series ( the new series) 120 gigas R$ 769,00

The 520 series is the replacement for the 510, and is faster and maintains the 510's reliability. Since its also cheaper, it would definitely be the way to go!

As thatguy said, go with the 520 – newer, faster, cheaper and also has 5 year warranty.

I ordered some 520's myself, but theoretical the 510 should be the more reliable series out of those 2.
I wouldn't be scared for the 520's to be unreliable in a workstation thou.
If you want something very reliable under very heavy I/O load conditions you would chose enterprise SSD's anyway, those are very expensive and are supposed to sit in servers.

Hello Mineria,

Thank you for your reply.

Why the 510 should be more reliable?
The enterprise I don't have money for this.

The 520 uses the infamous SandForce controller while 510 uses Marvell.
The SandForce controller had serious firmware issues to begin with, check OCZ Vertex 3 and others who where the first on the market with it.

Intel did put a lot of work into fixing and modding the controller (about a year) and surely wouldn't give the same 5 years warranty if it wasn't reliable, so go for the 520.

Just look at the difference between the 510 and 520 in this Intel 520 review
There is more than 3-10% performance difference, specially when you look at writes.

Thank you for your reply.

but I've not heard of any problems with the 510 series, 520 series already I've seen people complaining on the forum link in the review, people also saying is too early to make a conclusion. And the models considered professional has the Marvell controller. Forgetting speed, which one is the most reliable of the two?

Marvell controller best safe bet sandforce does not have a great track record thats why i switched to crucial M4 i wanted reliability

Thank you both. Well, I think I am going to get Marvell one. Everybody says is more stable.

I appreciate the kindness and all the attention people here gave me in your answers, thank you. I think I'll get even with Marvell and synchronous memories.
The model 510 has synchronous memories?

Mineria · *Last edited by Mineria; 04-19-2012 at 18:11.*

510 and 520 come with Intel’s own ‘hand picked’ 25nm synchronous NAND flash memory.

Note that the 520 comes with a newer Sandforce Controller (LSI SandForce SF-2281)

No serious issues as far as I can see: http://communities.intel.com/communi...ew=discussions
