Corsair Neutron GTX 240 vs Samsung 840 Pro 256 - Twist

[derigueur]

So i'm in the market for a new SSD.

I was going to get the Samsung as everywhere i've seen has given it high ratings, until I saw the following article on AnandTech about performance consistency:

Does this mean that the Corsair will be more reliable in the long run or is the actual outcome of these tests negligible in the real world?

One thing I noticed, the test was conducted before the revised version of the Corsair was released with its new 19nm NAND whereas before it was 24nm:

I've been made to believe that a smaller NAND means a shorter lifespan of read/write:

Once again, is this negligible in the real world?

Can anyone explain this better for me if I haven't understood please?

Modern 3rd generation SATA 3 6Gb/s solid state drives form a very tight performance cluster. Consumers normally can't tell the difference in performance. Consumers would have to run synthetic benchmarks that grossly exaggerate the minor differnces in order to measure them. It has been fairly well documented by Tom's Hardware and other sites that publish technical reviews.

There are different types of memory used in solid state drives and they do have different life expectancies (p/e cycles) The shortest lifespan is associated with triple level cell (TLC) memory which is approximately 7 to 8 years if a consumer writes and deletes 10GB of data every single day of the year for the entire 7 to 8 years. I do not know of any consumer who writes and deletes 10GB of data every single day year after year after year.

TLC memory is nothing new. TLC memory has been used in numerous small electronic devices over the years. You can find TLC memory in GPS devices and cell phones. The reason TLC memory is being used in solid state drives is to help reduce the price of the ssd's.

Ok, I see, thanks. So with that, Samsung here I come lol.

Is the emboldened part theoretical or true in actuality?
Also do you have any knowledge in relation to the NAND sizes and lifecycle e.g. less nm means shorter lifecyle.

id get neither of the above SSDs. a plextor m5s 256gb is 159.99 and performs relatively great compared o the solutions above for MUCH cheaper.

Not here in Europe, difference between plextor and Samsung roughly £22.

if its the difference between a 840 pro and the m5s. you may as well go for the 840 pro. otherwise, dont bother with a regular 840
