5 out of 5 eggsGood SSD

This review is from: SAMSUNG 840 EVO MZ-7TE1T0BW 2.5" 1TB SATA III MLC Internal Solid State Drive (SSD)

Pros: Fast
No Noise
Speed/Reliability is pretty high for all Samsung SSD's

Cons: None, Works as advertised

Other Thoughts: Bought 2 on Sale for 380 in late 2014 when the sales were on going. The 850's came out so I might wait to buy these until they are on sale

1 out of 5 eggsDO NOT BUY

This review is from: SAMSUNG 840 EVO MZ-7TE1T0BW 2.5" 1TB SATA III MLC Internal Solid State Drive (SSD)

Pros: Cheap.

Cons: There is a bug with all 840 EVO SSD's from Samsung. Read performance on this drive slows to less than 50mb per second after a few months. Samsung released a "Fix" in October 2014 but it isn't a fix and only restores drive performance for a couple of months at best before needing to re run their "fix".

The fix works by rewriting the entire contents of the disk which can't be good for the SSD lifespan. In addition, the fix cannot be applied if your controller is in RAID mode or the disk is configured as Dynamic disk. The fix process also takes 6+ hours on a 1tb drive.

Overall a complete waste of money.

5 out of 5 eggsFast and reliable, once it was working

This review is from: SAMSUNG 840 EVO MZ-7TE1T0BW 2.5" 1TB SATA III MLC Internal Solid State Drive (SSD)

Pros: This SSD is fast and reliable. I have not had the aged-file read slowdown problem that plagued many users.

It's been in service for six months now.

The Samsung Magician software makes it easier to sort out the Windows OS settings to optimize operation.

Cons: When I heard about the aged-file read slowdown, the device was about four months old. I had to spend (waste?) an hour or so to make sure it wasn't affecting me.

Other Thoughts: This is in an old workhorse 3gbps SATA laptop. I had some early problems with bootup, which were solved by cleaning the SATA pins.

DON'T FORGET TO ENABLE the overprovisioning (use the Magician). You'll extend the lifetime of the device at the cost of some capacity.

5 out of 5 eggsAMAAAAAAAZING!

This review is from: SAMSUNG 840 EVO MZ-7TE1T0BW 2.5" 1TB SATA III MLC Internal Solid State Drive (SSD)

Pros: Made my 2011 Macbook Pro just as good, if not quicker, than a new Macbook Pro, and for way cheaper.

Cons: I bought the 1TB. Guess there not in as much demand so anything above 750gb is a lot steeper of price.

5 out of 5 eggsAmazing!

This review is from: SAMSUNG 840 EVO MZ-7TE1T0BW 2.5" 1TB SATA III MLC Internal Solid State Drive (SSD)

Pros: I think this drive is very fast, and with its 1TB capacity, it holds lots of stuff.

I use this drive to store pics, videos, and music to share with multiple devices in my home. I perceived a noticeable increase in speed when transferring files around the network with this drive.

I ordered one when they were on sale for $350, which I think was a good deal.

Cons: None.

4 out of 5 eggsGreat speed bump

This review is from: SAMSUNG 840 EVO MZ-7TE1T0BW 2.5" 1TB SATA III MLC Internal Solid State Drive (SSD)

Pros: Reduced laptop boot time by 90% and extended battery life.

Cons: Not as much of a speed boost as I had hoped. Not really a con, I guess.

Other Thoughts: I had hoped the SSD would speed up general operations more. I don't really notice a change except for boot time.

1 out of 5 eggsVery slow read speed over time

This review is from: SAMSUNG 840 EVO MZ-7TE1T0BW 2.5" 1TB SATA III MLC Internal Solid State Drive (SSD)

Pros: Price

Cons: Read speed on older file degrade very much. Samsung released a fix + firmware update but that did not fixed the problem.

Read speed can go as low as 50MB/s or less. Unacceptable.

DO NOT BUY

1 out of 5 eggsDo NOT buy. You will regret it.

This review is from: SAMSUNG 840 EVO MZ-7TE1T0BW 2.5" 1TB SATA III MLC Internal Solid State Drive (SSD)

Pros: When I originally bought this back in 2013, it was the most affordable large SSD on the market.

Fast (at first).

Cons: Data reads get exponentially slower as data ages. After 14 months running mine, I was getting 3-5 MB/s (worse than USB1.0!) reads on old data. I thought my drives were dying and then I discovered that there is a bug with the firmware algorithm that would slow reads on old data.

Other Thoughts: Glad I waited over a year to review this as I would have been glowing about them when I first installed them.

There is definitely something wrong with these drives that I am not sure can be fixed with firmware. I think it is best if you avoid SSDs that use Triple Layered Cells (TLC). Unless you want your system to slowly degrade in performance, and then forcibly rewrite all your data once every 3-6 months (thereby reducing the life of your SSD).

Go MLC on your SSDs! Don't make the same mistake as the rest of us. Samsung has one last chance to make this right via software, but then I fear they will need to recall these drives or a class action lawsuit will probably be following.
