TLC is less reliable

TLC drive has a maximum write limit of ~1000 write per cell. MLC drive has 3000-5000 writes, and SLC drive have 100,000 write limits. This basically determines how long a drive will last(depending on how hard you work that drive), the access time, and how much power it uses.

Quote from htin : http://www.anandtech.com/print/5067 TLC is less reliable

Reliability is determined by how often you write to the drive. A Samsung 840 250GB has an estimated life of 23.4 years if you doing 10GB of data writing everyday. A 500GB would double that to 40 years. Does a drive life really matter if you switch SSD/HDD every 3-4 years?

A sensible way to look at it is that this 500GB TLC NAND drive will have a longer lifetime than the 128GB MLC NAND SSD you are probably replacing - so this "unreliability" stuff is simply FUD.

Very fast ez to install. Software and firm ware Great.
Wish I had more money to get three more.

Nice job Samsung. You keept the price down and delived a great product! Hope to see more like this. Thank you.

as has been said many times before. Samsung replaced 830 series with 840 at around same price point BUT is using different chips in the 840 series that supposedly are lower rated than the chips used in the 830 series. Do I have that right guys?

How do you know this?

Less reliable in terms of what?

It's right on this page. http://www.anandtech.com/show/645...f-tlc-nand
Chip manufacturer list their specs for their flash chip and write limit is one of it.

MLC used to have 5000 write limits where the flash chips were produced with the >35nm process. Once chip manufacturers like Intel/Samsung transition over to the <35nm process, write limit got reduced. The 25nm that current MLC drives use have around 3000 write limits. http://www.storagereview.com/ssds...ed_to_know

Yes, the 840 are slower and don't last as long as 830. You do have to ask yourself what kind of applications are you using the drive for though. It is still really fast and last pretty long for a normal user. This drive isn't meant to be used for enterprise or heavy level workload.

Great price! I am just waiting for the $260 shipped price and im in for 2 (desktop and laptop). I would of got this but my 128gb M4 drive still strong.

To people who think TLC is "less reliable" doesn't know what they are talking about. They are just as reliable but doesn't last as long based on how many times data is written on it over and over. Keep in mind that for the average person, these could last anywhere from 5-10 years easily. It's not about reliability. It's about LONGEVITY people are worried about and I am not worried about that at all. After 5 years... I am sure technology will be much different.

Average person = surfing the net and streaming videos here and there.

Unless you are working through data 12 hours a day download/encoding or whatever takes up HD space, the 2-5 year life span may be true but still far fetched.

Did Amazon ever offer this price? If not, they should now!
