Average Bench: 91.7% (243rd of 1003)

Based on 48,744 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]

Fast and Cheap SSD for a great price

Comment 

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.
