Not sure what to believe because I'm no expert, but this test seems to be rather backed up.

One of the benefits of the EVO is reliability. They're all going to be ridiculously better than what you're capable of using though. I think the calculated lifetime of the EVO was like 52 years or something. You can find that in the Guru review or the Anantech review, forgot which one.

A bigger drive with spare space (beyond what is pre-allocated by OEM) is a better choice. TLC will last plenty as long you don't fill the thing beyond 80-90% and you are not writing 50+GB daily. The NAND will likely last longer than the controller which is the main issue the last I had a discussion with the SSD/Storage guys on these forums and others. So, considering the small price difference but big space difference why would you want a 840Pro 128 when you could get the 250GB EVO?

I won't be using the drive for super crazy transfers all day every day. Just the OS and a single game will be on it.

Won't need a 250GB SSD as a 120GB EVO is plenty enough for me.

Thanks for input, though.

Samsung 840 PRO 128GB is better but Samsung 840 EVO 120GB is already good enough (gets pretty close to PRO actually which is pretty impressive).

I'd like to reiterate though, as others have mentioned the EVO uses TLC NAND (same as 840 Basic) so no, it's not going to be longer lasting than the PRO. The TLC as SLC thing is more of a trick to increase performance (at least for the first 3/6/9/12GB) as TLC NAND is inherently slower than MLC NAND. It's not meant to increase drive life. If Samsung were to treat the NAND in the EVO 120GB as all SLC, it would only have an effective storage space of around 40GB. That said, even a 120GB TLC NAND already has fairly good longevity so SSD life isn't something I'd worry about unless you have abnormally high usage and/or workloads with high random small-block writes.

for a normal user, no difference.
if buying today 250gb seems like the size to buy.
