For a flash drive enthusiast, you probably already has some brands and models on your mind. When looking for a solid-state drive, what you must consider are the capacity, performance as well as the price and all of them seem to be available in both Samsung 840 EVO vs PRO models. These SSD from Samsung are a great choice for those who need a faster boots and faster program loads as well as seamless multitasking but don’t want to spend so much.
In this article, we are going to give you information about:
– What are Samsung 840 EVO and 840 PRO
– What Samsung 840 EVO and 840 PRO can offer to you
– Samsung 840 EVO vs 840 PRO
Samsung has upgraded their SSD products in few years back because their first product wasn’t meet their customers expectation. The company seems to continuously learn to give their customer what they want with the released of 840 EVO and PRO that comes not long apart. These two are rated as great and eventually has very similar performance depend on what you are going to use them for. Even though the SATA III protocol has been exhausted and significant speed increase can’t be done anymore, Samsung keeps their innovation running.
About Samsung 840 EVO
If we are talking about their difference, the most obvious one is of course the price because as it has been mentioned earlier, these two have quite similar performance values for reading and writing but somehow priced differently with Pro being the less affordable one. The fundamental difference is the memory type used and the associated service life. What’s make a distinct difference in NAND Flash memory of home users SSD are the MLC, TLC types because these two are the most common for home users.
Samsung 840 EVO Features
The Samsung 840 EVO is released as the successor of the original 840 model, which is released a year earlier and just like the naming, it is the older model evolution version. The original 840 models were the first large scale consumer SSD made with 3-bit-per cell MLC NAND or TLC NAND and over the time, the company proved that it is one of the better values on the market. Just like its predecessor, taken from anandtech, the EVO version still uses 3-bit-per-cell TLC NAND but it now upgraded to moves to a smaller process geometry.
Together with the NAND update, the EVO model also has a significant controller upgrade. Even though the MEX controller is still the same triple cortex R4 design, it cores now runs at 400MHz while the previous version runs at 300MHz, which is why this model has significant performance. This upgrade also brings update to SATA 3.1 that known to brings a number of features that the most interesting being the support for queued TRIM commands.
Samsung 840 EVO has AES-256 encryption and PSID printed on the body just like Crucial’s M500. You can use the PSID to unlock the drive in the event that you set and lose the drive’s encryption key however your data will still be lost. When it was launched, the SSD doesn’t support TCG Opal and Microsoft’s eDrive spec but the firmware update released not long after finally enabled these things.
Samsung 840 EVO Price & Warranty
The new Samsung 840 EVO is priced as low as $172.71 for the 250GB capacity, which makes it around 70 cents per GB and this model also comes with 3 years warranty.
About Samsung 840 PRO
Samsung 840 Pro is released along with the original 840 model in 2012. What’s make them different is the fact that original model uses TLC NAND while this PRO version uses MLC NAND. This model comes with the company 21nm MLC NAND and this move will also bring the NAND pricing lower even though the company was hoping to see they are in par. This improvement also combined with Toggle 2.0 NAND interface with block and pages still remain the same and maximum capacity per die still at 8 GB.
Samsung 840 EVO Features
Samsung 840 PRO uses Samsung 4th generation SSD controller, which is the MDX controller. The basic architecture of this controller is still the same like Samsung’s previous models but now it contains ARM Cortex R4s inside this new MDX controller. The MDX has AES-256 encryption engine, which is managed using a system BIOS password just like many other SSD in its class.
In this SSD, the controller is combined with 512MB of LPDDR2-1066, which doubled up the DRAM used in the previous model and also increasing the bandwidth to DRAM by around 33%. The spare area by default is set at around 7% but you can adjust it using Samsung’s SSD magician utility.
Samsung 840 PRO Price & Warranty
The price for new Samsung 840 PRO is currently at $325 for the 256GB capacity, which makes it around $1.2 per GB and unlike the original version, this one comes with longer warranty at 5 years as opposed to 3 years warranty.
Now, let’s compare the difference between Samsung 840 Evo with 840 PRO. After reading the short article above, we are sure you are already know hat set them apart from each other. Their basic difference is the type of their NAND flash because EVO uses TLC just like the original 840 model while at the other hand PRO uses MLC.
We know that commonly, NAND flash has 3 types the SLC, MLC, and TLC.
The last two types is the consumer model, which are priced pretty affordable for us to purchase. But has less data read/write life than SLC. If SLC life cycle is expected to be between 90.00 and 100.000, MLC is only at 10.000 while TLC is lower at 3000-5000. MLC is better than TLC because if you are a person who works with high-write applications or does a video production, the lifespan of your SSD will be quicker, so choosing MLC probably won’t be a good idea.
Samsung 840 EVO Vs PRO
All in all, the decision is all yours to make. In our opinion, you need to match what you are going to do with the SSD to the model you are choosing. Both of them actually has similar performance and if you are not doing heavy loads, the cost efficient EVO is the one to go. However, if you plan on using it for business or heavy write/reads, the Samsung 840 PRO is the better option.
