New Intel 520 Series SSD Taps SandForce Controller
crookedvulture writes "Intel continues to partner with third-party controller makers for high-end SSDs. Its new 520 Series drives pair the latest SandForce controller with Intel's own firmware and 25-nm NAND. HotHardware, Tech Report, and PC Perspective all have reviews of the drive, and the verdict is pretty consistent. While the Intel 520 Series offers slightly better performance than competing SandForce solutions, it also costs 30-40% more. That's a steep margin even considering the Intel SSD's five-year warranty."
Congratulations, you win 1 (one) ASCII boner.

Ad yet my X25M, which came at a steep price, is still performing well 1.5 years later while several others I know have gone through several competing drives in the same period. Anecdotal, I know, but when I decided on a drive, the only one without the kind of failure stories my colleagues went through was the Intel drive. Sometimes you do get what you pay for.
The cesspool just got a check and balance.

I get really worried when the warranty is so short, I would be extremely frustrated if the thing conked out the day after. Whereas after 5 years, I would probably be ready to move on.
I noticed the price comparisons with other SF drives differ GREATLY depending on the capacity of the SSD you're looking at. When checking the 120GB version, the price difference isn't that bad, and if you're using it as a boot drive (as I hope you are), then the peace of mind seems well worth the extra money. Amazon has the 120GB version for around $230 or so.
I just returned an OCZ Agility 3 due to it dying after 2 weeks of light use as my Linux root partition running XFS. Since their office was local I drove it there to save shipping charges and had to laugh in their lobby since they're touting reliability. Sadly Sandforce has gained a reputation for not being the most reliable controller out there. I have never had a hard drive fail except after years of use until this one died. Fortunately it's being replaced under warranty.
Also, unlike other drives I've had fail, this one died suddenly and completely. Suddenly Linux couldn't access the root filesystem and after rebooting the drive could not be found by the SATA controller. Fortunately I had my old Western Digital Velociraptor drive I had replaced so I swapped that back in.
I have another Sandforce SSD that would often not show up when my computer woke up from standby until after a firmware update. Intel might be better, having written their own firmware, but at this point I think SSDs have a way to go in terms of reliability. There's no excuse for the issues that have been reported with the various Sandforce drives. The problem is either insufficient Q/A testing of the firmware or management pushing out the firmware before it's ready. It's also possible that there might be some hardware glitch causing these drives to fail.

When I bought my 2nd SSD a few weeks ago (first was an M4 for my laptop, this being for my desktop), I opted for a 128GB Samsung SSD 830. It's a great little drive, and was ~30% cheaper than Intel SSD 510.
I went for the 830 over a Sandforce-based drive because of their reliability. There's a reason why Apple use Samsung SSDs in their laptops.
The Sandforce controllers use compression to increase speeds and reduce write amplifications. Thus, they choke on encrypted (incompressible) data. They also have a horrible record of reliability. No thanks.
Unfortunately the Intel 320 series (really the X25-M G3) has had its own reliability issues with a nasty firmware bug that causes it to suddenly report its capacity as 8MB (causing complete data loss).
http://www.pcworld.com/businesscenter/article/236468/intel_acknowledges_ssd_320_bug_working_on_firmware_upgrade.html
Intel on Sunday acknowledged that a bug could cause its SSD 320 solid-state drives to fail, and said a firmware upgrade is on its way to address the problem.
In some instances, a power loss may cause Intel's SSD 320 drives to crash and lose data. On rebooting the system, the system BIOS could report the SSD as having only 8MB of storage capacity. Intel two weeks ago said the error was possibly a bug, and that the issue was being investigated.
"Intel has reproduced 'Bad Context 13x Error' utilizing strenuous testing methods. This 'Bad Context 13x Error' can be addressed via a firmware update and Intel is in the process of validating the firmware update. A future update will define the schedule to deliver the firmware fix," an Intel spokeswoman said in an e-mail statement.
It's ironic that a power failure triggers this problem, since Intel had marketed the 320 as especially resilient to them:
http://www.anandtech.com/show/4244/intel-ssd-320-review
Intel always prided itself on not storing any user data in its DRAM cache. The external DRAM is only used to cache mapping tables and serve as the controller's scratchpad. In the event of a sudden loss of power, Intel only has to commit whatever data it has in its SRAM to NAND. To minimize the amount of data loss in the event of a sudden power failure, Intel outfitted the SSD 320 with an array of six 470F capacitors in parallel.
Some posters say it can happen without a power failure:

Intel said they found the cause and released a firmware update, but applying it seems to have actually triggered the bug in previously problem-free drives for many posters:
http://communities.intel.com/thread/24121?start=0&tstart=0
Intel has not acknowledged any problems with the fix, nor told anyone which serial numbers were affected. Nobody has reported on the bug since Intel said they fixed it, including Anand.
This issue was enough to convince me to buy something else (even though the 320 series would otherwise have been my first choice) when I had to shop for an SSD last month. I found a used "like new" (according to the SMART data, at least) X25-M G2 on amazon instead.
Interestingly, X25-M G2 prices have held steady ($2/GB or so) and only gone up over the last year. Yeah it's probably because of dwindling supply, but I can't help but suspect that lack of confidence in the 320 series may have contributed to an increase in demand for the G2.
3 extra years warranty 2/5. So you would expect to pay 40% more.
2 extra years warranty 3/5. So you would expect to pay 60% more.
So if you were just buying a warranty alone the price would be worth it especially since the summary states you're only paying 30%-40% more.
Add the fact that your buying from a top quality manufacturer is just icing on the cake.
Note the fact that HDD manfs have cut their standard warranty to 1 year, should show you what crap they are producing these days. Swapping hardware takes minutes, restoring data takes lots of hours.
The reason I always bought Intel SSDs was because they always had Intel controllers, and Intel controllers were always stellar. Intel for years prioritized random access and did it better than anyone else. The 510 series, the first to be released with a non-Intel (Marvell) controller, seemed like such a pointless drive, with worse random performance than the 2 year old X25-M.
The problem is that sequential numbers are always faster and therefore easier to market to people who don't know any better. The 510 served a marketing need, not an engineering one.
I don't follow the market as closely anymore so I don't know if the 520 series makes any more sense, but if we know that Intel was willing to sacrifice random access performance to use a Marvell controller. What will they sacrifice for a Sandforce controller? Reliability?
Besides, the well known reliably issues with SF controllers, i wonder if they fixed the resume problems that seem to crop up on a regular basis. The forums are full of people (including one of my machines) reporting their machines simply blue screen with some fairly high frequency when resuming with these drives. The problems seem to cross vendors too...
'Same bug' happened to my 16G Toshiba - generic - no fancy name. After 3 weeks of 12/24 usage, fail, no data, no files, says 8MB.

Liberty freedom are no1, not dicks in suits.
Had a Vertex 2. After 3 months it died overnight without warning, No PC I hooked it up to would even recognise the drive. Data was totally inaccessible, first time I've ever had this with a drive. Didn't appreciate having to RMA a drive with all my data left on it, appreciated even less that I had to send it recorded delivery to the Netherlands out of my own pocket.
I love how they state on their website that the mean time for failure is something like 130 years.
ie the 120G is really a 115G as reported by windows
formated its down to 106 Gb
yeah 100% false fake advertising.
How can they get away with it, a 120 is really a 115, if its 120 in hardware, but appears as 115, its still 115.
Im sure real 128G SSDs have a few hidden Gig as reserve, but its not advertised as a 135G.
Lucky I only used 60 out of the 120 (115) ((106))

One reason to buy Intel SSDs is the Intel controller and more-reliable 34nm Flash.
Now that it's sub-2k PEC 25nm Flash and the same buggy controller running buggy firmware everyone else is using, there is absolutely no reason to pay one red cent more for an Intel SSD.
Question - Intel had spun of their flash memory unit to merge w/ STM's flash memory unit (Intel's unit had only NOR flash, while STM had both NOR & NAND) into a company called Numonyx. That company was later acquired by Micron, which now makes all types of flash memory.
So I understand Intel making SSD controllers, but Intel makes NAND flash and SSD as well? Those things are commodity to begin w/, even more so than Numonyx's StrataFlash was, so if Intel had spun them off, why are they playing in this market? Sooner or later, the various manufacturers of SSD - be it WD, Seagate, Micron, Samsung, Toshiba, et al would make the price so low that it just doesn't make sense for Intel to compete there. And it's not like Intel's fabs would see more utilization, since they are processor i.e. logic fabs, and less optimized for memory than memory fabs are.
Also, is Intel's NAND MLC NAND, or SLC?
