Samsung Evo 840 SSD

Is the Samsung Evo 840 SSD a worthy purchase or should not be considered because of the firmware bug or is the fix by Samsung ok? God a good price on this. Want to hit purchase price today at latest 🙂
 
Before the latest firmware version, EXT0CBQ6, I did notice performance drops when running HD Tune, to where it dropped as low as 60 MB/sec on my 240 GB EVO. After running the performance restoration, the lowest is 398 MB/sec with a max of 400.1 MB/sec.

It seems any brand has potential issues if you look around enough and I've generally preferred SSDs with Marvell controllers, but I gave Samsung a try and it's doing well.

Never noticed the performance drop with my 840 evo. Ran the fix in last week though. It is very fast with the samsung magician ram cache.
 
The "fix" though, is only for the EVO drives, and not the vanilla 840. I haven't heard if Samsung has addressed whether the plain 840 will get a fix.
 
Yeah its the evo guys...
One last thing guys. Which one of the 2?
240GB Kingston SSDnow V300 for $88
or
250GB Samsung SSD 840 EVO for $108
 
Thanks Blastman. This has been a real eye opener. Now the thing is whether I buy the Samsung Evo 840 and slap it in my C2D E6600 or wait for another bargain. 🙂
 
Well my view of this...Windows as it is, is a 20GB or so install. Your usual office apps, other softwares should take about 5-10GB on average. Then you have games which, nowadays, are anywhere between 5-40GB PER game. Being given that you have to leave about 30% of the SSD free for optimum use, I personally think that a 240GB is the minimum unless you will only install OS/Apps on the SSD.
 
After owning 3 840 EVO 1TB SSDs, I would never buy a TLC again...like EVER!

Stick to any MLC SSD slike the Crucial MX100 or SandDisk Extreme II or SanDisk Extreme PRO or Samsung 850 PRO

The Samsung FIX is just a temporary fix, then give it some time, and performance drops again, these drive suck plain and simple and only shine in benchmarks, in real world performance, I would take an 840 PRO which is cheap now any day over the EVO
 
Thank you berry. This is the kind of first hand user experience I was looking for. I'll look for a deal on a 840 Pro or 850 and snap one. This SSD will be re used in a future build next year.

Temporary? Mine still works fine and I applied the fix the day it came out...
 
He's just anticipating that performance will drop again over time because the fix essentially refreshed all the data so it's new on the drive again and thus doesn't suffer from performance degradation on old data.

I'm willing to give Samsung the benefit of the doubt, but I also have an OEM Samsung 840 SSD in a relatively new workstation laptop and it has performance issues as well, but since it's end of life, Samsung probably won't ever fix it.

Interestingly enough, HD Tune is the only benchmark tool that showed performance issues on my EVO prior to the fix.

Hmm well it was also a firmware update to fix and also prevent it from happening in the future.
 
bought an evo 840 once, and will never buy it again unless it's extremely cheap. 'cuz it's extremely fast, without the 840 "PRO" guarantee.
don't get me wrong though, someone I knew had an 840 "PRO" line that failed within days of NIB purchase, and had to return it for a swap.
recommend intel 730 to save money on reliability, or 850 pro if you want performance/10yr warranty.
 
OK so I just bought an 840 EVO SSD. As it's currently unformatted and empty I assume that I only need to connect it and update its firmware, is that correct?
 
The Samsung was $25 cheaper so I went for it...If I was quicker, I would have saved $33...But then again, I needed to wait for more opinions 🙂
Thanks all.

Please back up your allegations with fact and sources.

As expected, the problem appeared again. After 2.5 months the performance in some areas dropped to 200 Megs/s. Both HDtune pro and HDtach showing it.
