Played with this on/off for a couple of years 3/7/2018 12:05:39 PM

Pros: Now it's been deployed in my Windows XP machine which has never run faster before this. I don't need a lot of local space as we use a central NAS for all of our data, but I have a half a dozen apps and some hardware that will not run nicely in Windows 7, hence the need to keep XP around for a while longer

Cons: None

4 years old. Random reads and writes no where near advertised speeds. 2/20/2017 8:04:31 AM

Pros: Has lasted as my work laptop drive for 4 years. 8 hours a day, 5 days a week.
Sign-in screen pops up in 18 seconds. Ready to go 5 seconds after password entry.

Cons: I just ran the Magician performance test. The random reads and writes where only at 29428/24830. The sequential read and write were a little low too at 527/280. Could be that I'm running it in a 4 year old laptop...

Overall Review: This is the first of 3 Samsung drives that I've purchased. The other 2 are both 850 EVO's. A 500 GB and a 1 TB. They are in my main home rig and are blazing fast. I've gotten so spoiled with the speed at which they operate that I sometimes get impatient with the 22 second boot time. Then I use one of the machines at work with platter drives and my joy of having fast SSDs is renewed.

Long time no use 11/19/2016 7:57:39 PM

Pros: Great product, finally getting around to using it. Speeds are as advertised in a more than last gen machine. Installed win10 on it and it has been running almost continuously since. Like the Samsung product line. May stick with them for all my ssd needs.

Cons: None,

Overall Review: In my opinion the Samsung drives are the best, though I have only owned Intel and Crucial drives, this Samsung beats them quite handily.

Good only for a limited time -not worth the money! 11/5/2016 8:12:29 AM

Pros: Then: (Great size for the price (got it on sale). works as expected of the SSD. Wished I had bought 2 during the sale.)
owned less than a year

**Revised**
now:
3yr 9 m later
Stay away from this drive . . .
-I bought this drive and it was fast and I loved it. 2 years later, it died with NO warning. I guess that's how SSDs die.
I got another one through RMA on the 3yr warranty and received a refurbished one. yeah all good and we back smoking, 1 year later it dies (of course, now we pass the 3 year warranty, now).
sent in a request for a RMA and we straight out of luck. the warranty period is gone.
-I barely use the drive on this computer. I used my cheapo PNY 250GB drive primarily and booted to this one every one in a while. I am very disappointed in this drive. It cost more than my primary drive and I never got to gain confidence in it to make it my main drive because it was not reliable.
**Samsung is great but choose another manufacture for the SSD! this was my story, others on here are similar, don't bet on being on the other percentile, it's just a lot of man hours and disappointment. they don't compensate you for that**

Cons: None

Solid performed 10/20/2016 7:14:45 PM

Pros: Running > 3 years in my rig and still no issues. Samsung utility still rates health as "Good" after 12.33 TB written. Was my boot drive, but since transitioned to my scratch drive (with OS / user temp files and video source files) after I replaced it with an 850.

Cons: is not an 850

Overall Review: Read your reviews - the 840 and 850 series sat atop TomsHardware's ranking list for quite a while - although they seem to have been displaced in recent rankings for smaller capacities. Reliability matters more to me than performance, although this has delivered both.

3 years and 2 months later FAILED! 8/9/2016 8:04:59 AM

Pros: 2 month after warranty the drive (1 of 2) just failed. This technology is old and Samsung makes much better drives. Overall SSD performance will vanish if not adequately cooled. They rate will throttle to 1/5th of its potential once thermo governor kicks in.

Cons: Failed after 3 years

Overall Review: I would not recommend this particular technology.

Great SSD 7/31/2016 4:30:12 PM

Pros: Great performance

Cons: none (maybe price when I purchased it a long time ago)

Overall Review: I have to say that never had any issues with Samsung SSDs they are up there with a few other manufactures. I have a number of brands of SSD's and most have been doing good, only failed SSD I ever found was from my family member who did not take care of it.

It was one of the first gen 60gb (OCZ Agility), that I had set up for boot only, and specifically had stated to use HD for storage, later came after few years, to find them complain system is slow and not working at times. The drive was completely full, sadly that drive did not make it. If it was any longer it would have been completely dead, performance was horrible and I tried after transferring data to revive the drive, formatting, flashing firmware etc... nothing helped.

FYI word of caution for those who think of flashing firmware on SSDs, always read what is required and what will happen. Also try to research others who flashed if there were any issues.

Running like a champ 6/22/2016 11:18:16 AM

Pros: This hard drive has performed perfectly for 3 years, no problems.

Cons: I didn't actually have a place to mount the hard drive in my case, and it doesn't come with any mounting hardware, so it's just kind of dangling in there...

Overall Review: I'm probably a low to average disk user - a couple of OS upgrades, 50+ steam games written and removed, but not a ton of frequent read/write operations to the OS disk. The bulk work goes to my storage disk.
