Samsung MZ-7TE120BW

840 Evo 120GB

▲ 5413,088 ▼

Controller: Samsung 3 Core MEX. Memory: Samsung 19nm Toggle Mode TLC. Release date: Q3 2013.

Average Bench: 91.4% (320th of 1080)

Based on 104,444 user benchmarks.  Models: Samsung SSD 840 EVO 120GB, Samsung SSD 840 EVO 1, Samsung SSD 840 EVO 120G, Samsung SSD 840 EVO

The 120GB Evo, like its 250GB sibling, features a second level Turbowrite cache (TWC). This 3GB block of high speed SLC memory allows the Evo to write data at 370 MB/s, nearly double its normal rate. When the TWC is full write speeds drop by around 50% but since consumers generally write less than 3GB in a typical write operation, the performance drop will rarely be noticed. On the other hand, in a server environment this sort of performance degradation would be unacceptable. Comparing the 120GB and 250GB Evos shows that they have similar performance profiles. The performance equivalence between the different capacities, coupled with the fact that their prices are almost linear, implies that both capacities represent roughly the same value for money. Within its TWC, the 120GB Evo is capable of chart topping burst IO rates and it sits squarely amongst the best performing 120GB drives. [Aug '14 SSDrivePro]

Good for general purpose use - best compromise between Price and performance. I have bought over 20 of these to retrofit into Laptops and desktop pc's to give a performance boost especially with a clean Windows 8.1 install. Makes a cheap Celeron Laptop fly like a new core i5 laptop with a standard electro-mechanical Hdd. PC World will not sell computers with SSD's in because if people savvy the huge performance boot you get with an SSD they will just buy a cheap sub £200 laptop and clone the disk to an SSD. Dell hike their prices to fit a 250GB SSD when you buy a new PC by £350 - WHAT A RIP OFF, No wonder they are going out of business. The 250GB and 500GB Samsung SSD's are equally good - recommended in fact. I have bought all of these in some quantity.—Oct '14

Works really great. I've had it for 3 months already and had no troubles with it. It's fast and cheap. My 4 year old HP DV7-3180us feels like new with it.

Top of the pack back in the day: I purchased this baby at nearly 1€/GB possibly as far back as 2014. This workhorse was my Windows and Linux boot drive, and code compilation drive for several years. It absorbed everything I could throw at it through the SATA 3 bus, but given its capacity, at its peak and end-of-use, it didn't run very many of my programs beyond Windows, Steam, Firefox, and similar relatively small software you'd launch and use often. Could I have lived without it? No doubt. Would I say it was a good purchase way back when? Absolutely. Only downside were abysmal read speeds with the old firmware -- After a few months (years?) of data sitting there untouched, the read speeds would plummet to HDD levels. Thankfully a firmware update fixed this, possibly at the cost of endurance, but, even after abusing the drive much more than the average consumer would, I never even got close to Samsung's rated endurance.

Had this in my system for 5 years now. It didnt lose any performance or gave me any errors. Its still a fast little OS SSD and is still supported via software from samsungs side.

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
