AFAIK, BSOD issue still unsolved but some user have it some didn't, seems like depends on ur luck.. better choose non sf controller like intel or crucial to playsafe..

yup depends on luck. but when i was using agility 3 i had bsod before fw update. after fw update the bsod problem gone but got new problem appeared. pc became unresponsive sometimes and stuttering too.

what mobo and ssd r u using?
I heard most SF controller drives that update to latest firmware works well with intel 6 series chipset

When Intel entered the SSD market one of its declared goals was to bring the technology into the mainstream. The goal was so important to Intel that its consumer drive was branded X25-M, with the M standing for mainstream. Intel's desire for SSD ubiquity wasn't entirely altruistic however. Mechanical storage acted as a potential gate to increasing CPU performance. Eventually, without significant improvements in IO performance, CPU improvements would be less visible to most users. SSDs would help alleviate this bottleneck.

It wouldn't be untrue to say that Intel accomplished its mission. The client SSD market was in a state of disarray before Intel arrived on the scene. Although we still have problems today, there are a number of affordable options for end users and lots of competition. Samsung, Marvell, Indilinx, JMicron and even SanDisk are now vying for control of the market.

With healthy competition, significant performance improvements and (hopefully) improved reliability in the consumer SSD space, Intel will actually begin defocusing itself from this market over the coming years. Intel needs to keep margins as high as possible to appease shareholders, and the consumer SSD business is in a race to the bottom. Dollars per GB are all that matter here once you deliver a certain level of performance and reliability.

Intel won't abandon the consumer SSD market completely, it will still compete in the high end space but there's a good reason that the mainstream moniker has been dropped from Intel's product names. Intel will shift more of its attention to the enterprise space, bringing that technology to the high end desktop/workstation users where it can (e.g. Cherryville will be focused on both enterprise and enthusiast desktop users). But as you have already seen, I wouldn't expect Intel to actively compete in driving mainstream SSD pricing down further. That market now belongs to the players I mentioned above.

I hate it when such arguments make sense. Prices will come down, but it may take much longer. Here's to hoping that we can get 300GB SSDs for less than RM1,000 in a years time.

How long did it take to get to the current state where 2TB drives are priced where it is now? How many merges / takeovers? Unfortunately, companies like Quantum and Maxtor never saw the chance to produce 2TB drives.

Anyway, I digress since this is teh SSD thread...

I decided last weekend to attempt and transfer one of my smaller drives to the 64GB M4 first. I'm a little rusty as have not done this for a while and after some reading and numerous failed attempts to transfer the OS from old HD to SSD, I was almost tempted to do a fresh Windows 7 reinstall which I finally did reluctantly in the end.

My original drive is 120GB and has 2 partitions but hardly anything inside. Seems that copying it to the smaller 64GB M4 gives problems. I was a little disappointed when I found out my old Ghost 15 only supports cloning via image files. Anyway, after imaging to a file and imaging it to the new hardisk, it did not boot. I tried to repair the OS using Windows startup but turned out the same. I tried one or two other programs to transfer and was still unsuccessful.

Anyway, long story short, my Tecra M9 now has a new lease of life ! It was hard to remember all the drivers to get since officially the M9 only supports up to Vista. Will now find time to put the 128GB M4 on my Acer 1410 which I think is more difficult compared to the M9 because the Acer has full of rubbish in the 250GB drive. A little wiser from this experience but I hope it does not take too much time.

To the contrary, I have not had much problem with sandforce.
Perhaps I am from different camp.

My first ssd was Crucial C300 128GB tho. I have been using sandforce ssd ever since.

Nice but need to sacrifice that much just to test one specific model and one specific making.
Anyway one of my boss client has this SSD running SQL database and already has 7 Re-Allocated Sector Count, Media Wearout Indicator at 98(%?) and Host Writes at 3.62 TB.
Look good from the CrystalDiskInfo, did not felt any slows down so far. hmm.gif

It's 98% used up? That sounds rather unusual.

A 40GB SSD with lifespan of 3,000 writes and a write amplification of 10x should be able to write: 40GB x 3,000 / 10 = 12,000GB = 11.71TB

Or is it saying that it has already used up 2% of its life?

that indicator is not reliable. according to the test after it reaches 0 the indicator will then goes up again.. lol.. funny


Added on October 8, 2011, 12:27 amand for 40gb ssd they managed to write more than 200tb on that ssd...

Writing 200TB on a 40GB isn't impossible if it has a SandForce-controller. With data compression, its write amplification factor can actually be less than 1, perhaps approaching less than 50% for text. 40GB x 3,000 writes / 0.5 write amplification factor = 240TB.

Also, Anand has stated that most manufacturers claim it isn't unusual for NAND memory to have much more than 3,000 p/e cycles.

from this test they used a few ssd. intel, sandforce controller, all of them manage to write more than 200tb

From the first page alone, they were using the old stuff, I think with 5,000 p/e. With a write amplification of 1, that's 40 x 5,000 x 1 = 200TB. No surprise there. smile.gif

actually more than 200tb. some even reach close to 400tb!! funny.. but 1 thing we cannot rely on the wearout indicator, it seems when it reaches 0 still not at the end of ssd life yet. blink.gif hmm.gif makes us wonder how long can an ssd really last????

In fact, I've often heard from manufacturers that hitting up to 30K p/e cycles on standard MLC NAND isn't unrealistic.

Source: http://www.anandtech.com/show/4902/intel-s...-200gb-review/2

So instead of only 3,000 p/e, you can get 30,000 p/e by chance!

nice.. apparently we have not to worry loosing space in the near future...
