Inside the Intel SSD 335

Similar to the SSD 330, the SSD 335 has a single thermal pad covering the controller. The whole case is made out of metal, so heat dissipation in general should not be an issue. There doesn't seem to be any visible differences between the PCBs of SSD 335 and 330, other than the fact that the SSD 335 loses the "BIN 2" sticker and is manufactured in fab 4 instead of fab 3 (although it's completely possible that SSD 335s are manufactured in fab 3 as well). 

The SF-2281

As usual, there are a total of sixteen NAND packages, eight on each side of the PCB. Each NAND package consists of two 8GB 20nm MLC NAND dies, making each NAND package 16GB in capacity. The new 20nm process node is indicated by the 12th character, which is an F. Process nodes follow the alphabet, meaning that F is 20nm, E is 25nm, D is 34nm and so on.

    Do you have any hard data to back up this these assertions? Or are they just your unfounded opinions?

    I ask because the SSD 830 has a terrific reputation for being reliable. It has even demonstrated an exceptionally impressive lifespan over at XtremeSystems Forums.

    Yeah, where's your data on that? I'm not aware of any data that suggests the 830 is less reliable in any way than Crucial or Intel. And my perception from experience and reviews are that Samsung has a significantly better reliability record than Sandforce. All vendors have had firmware issues to some degree, and Intel has had some pretty significant ones. The 8 MB issue on the 320 that caused data loss comes to mind. Reply

    Honestly the first Intel SSD I've come across dead was an SSD520 120GB, just wont detect by the system, clearly a Sandforce controller problem.

    I'd never seen an Intel SSD fail until now that (August 2012) and Intel has made a big mistake joining the likes of OCZ quality with its Sandforce marriage.

    You must forget about all the issues that plague hard drives. Reply

    To what "Samsung drivers" are you referring? You don't need to load any drivers for this or any other SSD (at least in Windows 7, 8 and Server 2012). The driver is provided by Microsoft and has a date of 2006.

    And I'll note that Samsung SSDs are not plagued by the infamous "Sandforce controller bug." And that Samsung makes the controller the NAND and everything else in the SSD.

    So how again, is it less reliable than other SSDs?

    I don't think you know what you are talking about. I have two Samsung 830's and use them everyday and push they quite hard. Haven't had 1 single issue. I haven't heard of any problems with them either. Reply

    It all depends about the market Samsung 830 128GB is here 170USD while 256GB version is 400USD so they aint affordable at all. While Intel 520 series 240GB costs 350USD and 120GB 180USD respectively Reply
  • seapeople - Friday, November 02, 2012 - link

    So $170 and 128GB is less affordable than $180 and 120GB? You live in strange world. Reply

    I dont see the need for all these various models. Make a value drive and a high end one. You either buy cheapest or best. Reply
  • Kristian Vättö - Monday, October 29, 2012 - link

    That's essentially what Intel offers. SSD 335 is the value drive, whereas the successor of SSD 520 will be the high-end one. SSD 335 and 330 are basically the same and 335 will replace the 330 sooner than later (I'm hearing Q1'13 for the other capacities). Reply
