Yeah, one's my 3TB. It's died once already but was just out of warranty and WD never got back to me on an RMA. Somehow it came back to life long enough for me to grab pretty much everything off of it; it's only plugged in for the odd stuff I couldn't back up (since it's my most massive drive); it could die right now and I wouldn't care. That other one, Disk 4? I didn't know about that one, though. Better start backing up...I wonder how much a 4TB costs these days?

From what I was reading on overclockers, the problem with the EVOs are specifically limited to the 128/250 GB models. They have found that a secure erase, meaning using a specialized app to totally zero out the drive, will restore performance to brand-new-drive levels.

Most people who are experiencing the issue are taking an image of the drive, using another program to secure erase the drive which zeros it out, then they reapply the image back to the drive making sure that the alignment is correct. This seems to fix the problem.

However, it has not been determined whether or not this is a short-term or long-term fix. People don't know if the drive will eventually go back to being slow. Well, "slow" for an SSD.

Well, I'm glad I bought a 1tb drive if this is true. Nice to have a bit of extra piece of mind.

This is my 1tb EVO, with rapid disabled:



It's been in use since march. I've never noticed a problem (I guess keeping rapid on helps to mitigate the issue?).

If this turns out not to be fixable via firmware update, what are the chances of samsung issuing a recall? Have they given any indication that they are aware of the issue and are investigating?

The performance difference to me is huge. How badly will disk refresh affect the life span of the drive?

Do you have rapid mode on? that significantly masks the issue, I had no idea I was even suffering from it till I read about it here and decided to test it out. even without the issue it's a massive performance bump and it should always be on. The symptoms you describe sound kinda weird though. Are you sure it isn't some other issue?

I'm hoping they hurry up and bring out an 850EVO so we don't have to keep telling people about it. It doesn't give the best impression when you're talking people into buying an EVO, when you say, 'oh yeah, make sure you download the performance repair tool to fix this teeny issue the drive had'.

Did Samsung genuinely release a firmware update that can't be installed for many people with Evo drives? That doesn't make much sense, somebody tell me I'm misreading the situation.

They released a firmware update that isn't installed via samsung magician, nor is there any kind of prompt in magician - and there is no sign of any notification about the issue on the samsung website. Instead, you have to engage in an invigorating session of website spelunking, in order to dive into the bowels of the samsung support website, to find a download for a 'performance restoration tool' which installs the new firmware, followed by a once off correction of the existing problem by rewriting all the data on the drive. This tool is strictly windows only, and the standalone firmware available on the site is the previous one, so literally the only way of installing this bug fixing update is to use a piece of windows only software. There is no linux download for firmware available period, so I'm not sure if linux users can ever update samsung firmware.

Even windows users would need to be sufficiently interested in technology to be reading sites like this or anandtech, and be directed to samsung's website for a fix, otherwise they may not even know the issue exists.

That being said, this is one of the best reviews detailing what exactly "RAPID Mode" does on the EVOs: http://techreport.com/review/25282/a-closer-look-at-rapid-dram-caching-on-the-samsung-840-evo-ssd

Does wonders for random access speed (if the files it's caching are <1GB as that's the max it'll take from your system RAM), but unless you're bragging about CrystalDiskMark scores, it won't do wonders for boot time or level loading. The delta between enabled and disabled are so small that they're practically a null-set margin of error.

RAPID mode was improved a fair bit in a firmware update a while back, it can use a lot more than 1gb of RAM if you have RAM to spare now. On my PC with 16gb I can confirm it using up to 4gb.

At that point you'd RMA to the manufacturer, not the vendor that sold you the drive. So a vendor wouldn't have much useful data beyond whatever their return period is.

If you were in the states you would. Australia, the UK, and I suspect much of Europe has much stricter consumer protection laws though. In Australia you would never deal with the manufacturer, because retailers have a legal obligation to give you a refund for goods that don't last a reasonable period of time, and that time period often exceeds the manufacturers' warranty.

I got a full refund for a 2.5 year old 5970 because the fans weren't spinning properly.

This is why extended warranties are basically a scam in Australia because they don't give you any rights you don't already have.

I know the UK has similar laws and I'm betting France does too.

So I'm going to do a clean Windows install this weekend and had a few questions relating to my 840 EVO. The OP says to over provision by only partitioning 80% of the drive, but I also read a few pages back that someone posted saying this isn't needed anymore if TRIM is enabled. So what's the deal then? And if I do need to over provision, do I do it on the advertised 500 GB or the actual ~477 GB? Also where did this 20% come from? Why not 10%, or 15%, etc?

Don't over provision, but don't fill the drive past 80%.

In what way is the 850 EVO a really expensive option, making little difference? Samsung and Intel SSDs are pretty much the only SSDs anyone should be buying, and the latter only for people with special needs. Rapid mode on the Samsung makes a huge performance difference. The only reason the OP doesn't say 'Go buy an 850 EVO' is because Alereon appears to have abandoned the thread and it hasn't been updated since September.

Have SSD prices cratered in the last six months? I was just shown a purchase order from late April/early May, and a 500GB 850 EVO was listed as bought for ¥60,000, or roughly $500.

That seems at least a factor of two too high, so now I'm wondering if someone screwed up.

It seems way too high by US pricing standards but judging from the people who've asked for advice in the PCPartpicking thread and been in japan, it's hard to find decent PC parts over there and stuff tends to be more expensive. I'd suggest using the links in the OP of the PCPartpicking thread to find a japanese PC hardware store and just checking what they sell for.
