SSD Deathmatch: Crucial's M500 Vs. Samsung's 840 EVO

Even 3bpc SSDs should last you a good ten years...

The SSD 840 is rated for 1000 P/E cycles, though it's been seen doing more like ~3000. At 10GB/day, a 240GB would last for 24,000 days, or about [strike]7[/strike]66 years, and that's using the 1K figure.

You're free to waste money if you want, but SLC now has little place outside write-heavy DB storage.

EDIT: Screwed up by an order of magnitude.

You are totally correct! You win a gold star, because I didn't even notice. Thanks for catching it, and it should be fixed now.

Not only are consumer workloads completely gentle on SSDs, but modern controllers are super awesome at expanding NAND longevity. I was able to burn through 3000+ PE cycles on the Samsung 840 last year, and it only is rated at 1,000 PE cycles or so. You'd have to put almost 1 TB a day on a 120 GB Samsung 840 TLC to kill it in a year, assuming it didn't die from something else first.

I'd like to see some sources on that - for starters, I don't think the 840 has been out for a year, and it was the first to commercialize 3bpc NAND.

You may be thinking of the controller failures some of the Sandforce drives had, which are completely unrelated to the type of NAND used.

Well, I must agree with Someone Somewhere. I would also like to see sources for this statement: "Yes, in theory they last 10 years, in practise they last a year or so.".
I would like to see, can TH use SSD put this 10GB/day and see for how long it will work.
After this I read this article, I think that Crucial's M500 hit the jackpot. Will see Samsung's response. And that's very good for end consumer.

It was sad that they did not include the samsung 830 128gb and crucial m4 128gb in the results, those were the most popular ssd last year.
 
You can also find tens of thousands of people not complaining about their SSD failing. It's called selection bias.

Show me a report with a reasonable sample size (more than a couple of dozen drives) that says they have >50% annual failures.

A couple of years ago Tom's posted this: http://www.tomshardware.com/reviews/ssd-reliability-failure-rate,2923.html

The majority of failures were firmware-caused by early Sandforce drives. That's gone now.

EDIT: Missed your post. First off, that's a perfect example of self-selection. Secondly, those who buy multiple SSDs will appear to have n times the actual failure rate, because if any fail they all appear to fail. Thirdly, that has nothing to do with whether or not it is a 1bpc or 3 bpc SSD - that's what you started off with.

This doesn't fix the problem of audience self-selection
 
You were however trying to stop other people buying them...

Sounds a bit like a sore loser argument, unfortunately.

SSDs aren't perfect, but they generally do live long enough to not be a problem. Most of the failures have been overcome by now too.

Just realised there's an error in my original post - off by a factor of ten. Should have been 66 years.

Tell that to all the people on this forum still running intel X-25M that launched all the way back in 2008 and my Samsung 830 that's been working just fine for over a year.......

See what you're paying attention too is the loudest group of ssd owners. The owners that have failed ssd's.

See it's the classic "if someone has a problem, there going to be the one that you hear and the quiet group, isn't having the problem" issue.

Those that dont have issues (such as myself) dont mention about our ssds and is probably complaining about something else that has failed.

Assuming the system has more than enough RAM to avoid needing any significant amount of swapping. If someone with 4GB RAM uses a 16GB swapfile to avoid upgrading to the 8-16GB RAM he really should have, he could end up writing over 1GB/minute.

I have ended up over-crowding my RAM many times in the past and it has a tendency to make my computers practically unusable when using mechanical HDDs at which point I had to spread my programs and swapfile across multiple HDDs to reduce the IO load on individual drives. I imagine this would burn through SSDs fairly quickly.

Anecdotal evidence is pretty useless. People with very good or very bad experiences tend to write reviews. People generally don't write reviews for random pieces of hardware that just work as expected. Provide citations with statistics to support your statements if you want anyone to take them seriously.

You are entitled to your opinion but you are making bold statements without any facts. A lot of people use forums like these to research products they are thinking about buying and you are spreading misinformation about SSD's without and evidence for your statements. I personally have 4 computers with SSD's in them that are over 2 years old and I haven't had a single issue or failure. It really pisses me off when people start spreading inaccurate statements that may turn away a potential user of a SSD. Out of all the PC upgrades I have done in the past 12 years the SSD has been the best most noticeable improvement I have done.

Disagreement among techies is inevitable, but please watch language.


Just to stick an oar into the reliability issue, my Samsung 830 has run reliably for over two years now. The only SSDs I had fail in use were a couple of Sandforce drives, but their replacements have thus far been reliable. I think InvalidError has a good point about RAM though; I tend to use at least 8GB, which probably cuts down swapping quite a bit. I also prefer to close programs completely rather than have a lot of windows open, which would also reduce swapping. With a SSD, they re-open pretty quickly anyway.

Wow, nice 180 there anti global. I have used many SSD's in both enterprise and personal use, and their reliability has been on par with enterprise level HDD's. We currently use a mix of Samsung 830/840's and crucial m400's for SSD's and with the increased capacity and incredible price drops, the m500 would be an easy drop in upgrade.

I've purchased 3 different SSDs over the last 2 years. My first purchase was an Agility 3 64gb that I used as a boot drive for my machine that I just build. About 6 months later I purchased an M4 128gb to be used for running select applications. About 6 months after the M4 purchase, I bought an 840 500gb. I moved my OS to the M4, applications to the 840 and gave my Agility 3 to my brother to be used in his machine as a boot drive. Never had a single problem with any of them. SSDs are fantastic. Pretty soon, when the price of the TB drives come further, the only mechanical storage I'll be using is for backups.

LOL, when you come onto an article about SSD's and say nonsense like you did, you have to expect to get hate buddy. MLC/TLC is very viable and lasts much longer than a year kid, some drives do fail, and if they do you get your replacement. Other peoples drives are not lemons and last a normal lifetime, common sense bro.

As stated, it was mostly sandforce drives that failed. Have bought 7 SSD's (Crucial, Samsung, Plextor) and all are working perfectly awesome (rather than just fine :p )

My wife is running an X-25M G2 and I just got an M500. The X-25M gave her at least two more years out of her system and the M500... holy cow is this thing awesome! Everything feels like it should.

Oh, I highly recommend getting the drive migration kit from Crucial for ~$20. It makes like much easier. It's a USB 3.0 SATA drive connector for your M500. Then just boot the supplied CD and run it in auto mode to copy over your drive exactly and make any sizing adjustments needed to the partitions to get it to fit. It works very nicely.

Isn't Crucial made by an American company, and isn't Samsung South Korean? Hmm...I know which one I'm buying. I'm a patriot. Sorry Samsung! (You make enough money on LCD screens anyway!)

Crucial's SSDs have always been at best middle of the pack performers. I am not sure why Tom's Hardware has been so enthralled with them.

Once again the 840 Pro is in the top three of nearly every test and is the clear performance leader IMO. While the EVO is interesting, the Pro has the chops to be the best without tricks like "turbo-cache," which is an interesting feature.

It seems like the quality of each new generation of nand memory goes down and not up. The smaller die sizes seem to be the culprit. It reminds me of the race to increase the number of pixels in cameras. Having more pixels does not guarantee better pictures and too many pixels can actually hurt the camera sensor's performance.

The never ceasing shrinking nand sizes appear to have the same types of diminishing returns.

well next gen's equivalent to 840 pro will be shrunk with similar performance im sure. They will figure out the smaller nand deficits to make up for the performance im sure. Otherwise they wouldnt be pushing it so much.

"In fact, builds 11.2 and newer support TRIM in RAID as well."

Did I read this correctly?
I chose a single SSD over a Raid 0 SSD to make sure TRIM command was supported.

Is this true about Intel RST?
