Back in the early days of SSDs, I bought an Intel SSD and wrote a program I called "brick" that continually wrote 1024-byte blocks to the same location as fast as possible to the physical SDD device ( bypassing the system write cache). The program recorded the time it took to write every single block. After about 13 hours the device "bricked" and no longer responded to I/O requests. I graphed the timing data and the resulting graph was amazing. The write operations were very fast until it reached nearly 100% capacity of the device then decreased to about half the speed for a while then degraded to about 10% speed until it died. I contacted Intel and told them my shiny new SSD mysteriously stopped working so they sent me a new one.

i still have a very old Samsung 830 after 10 years and it barely reached 20TBs written, lol! Still performing strong

I use Samsung SSDs exclusively for my personal builds as they have proven to be reliable time and time again :)

Evo is TLC (SLC cache), pro is MLC (no SLC cache so performance consistent across all writes and data reliability is higher) longer warranty as well

If you secure erase the 840 using the Samsung magician (I assume that is not the evo or even if it is works for that as well) it restore write perform back to stock I believe the Samsung magician can also restore the performance on the 840 none evo as well as there is a optimize button in the software (not had a 840 before only 840/850 evo) can take Some Time If its Never been run before, the firmware on the 840 is an issue as Samsung never released the fix that the 840/850 evo got so background optimization is missing on the older 840 drive, (pro drives don't suffer from data slowing down)

I bet if you do a secure erase on the drive, its performance will return to like brand-new. In my experience SSDs get some kind of internal fragmentation that affects performance and does not get resolved by just issuing TRIM to the entire drive. Doing a secure erase though gets the performance back to a fresh state.

Bought the 850 EVO in 2015 (June), and it's currently 29.9 T.B. (June 14, 2018) of data written, I was worried as it was writing T.B. fast out of nowhere, but I guess it was just arranging stuff since that scenario stopped happening. Long story long, I was worrying if the 75 T.B. rating was the end for it.

I had bought a used F80 800 GB drive a couple months ago for $50 on eBay with 7.2 years powered on hours that has of now only 13.65TB written to it. I think I got a good deal as it's lifetime endurance is 22 PB (22000 TB) and for being old it is still faster than my new SSD drives thought half the speed of my NVMe which is ok. I wanted the F80 to use as a cache drive and for encoding music and movies so the other drives will last longer in theory anyway. all my other drives are between 200 and 600 TBW

how can u see how much gb has been writing?

[Darkhalo]

My 240GB PNY SSD has failed after using it since 2014. Didn't hit the TBW limit, but it isn't working anymore

[gheckopoint]

I chucked a cheap second hand SSD in the digital TV recorder (think freeview TiVo type device)

[Limeayy]

I've only had 5TB's on my Samsung 840 Pro 120Gb. I bought it on june 6 2013 i believe.

[kheo]

do you know what type of data was written on it? e.g pictures or games or movies etc.

[AnthonyJordanWairoaboyNZ]

Bro keep bringing them on! New Zealand needs it

[markusTegelane]

That's 700TBW for those keeping track at home

[varunsharma]

Crystal disk mark shows my host writes as 300gb but i have written only 55gb on my SSD (newly bought laptop)? Is it ok or is there a problem? SSD is samsung MZALQ512HALU

[beefybeef]

How do you check the amount written over the lifetime?

[Limeayy]

I'm hoping to use my old Samsung 840 Pro 120Gb as a video scratch disk or something like that only if i get a 500Gb Samsung 970 Pro NVME m.2 SSD for my Z87 board. Would be friggin AWESOME. It's do-able, harder is to try and enable PCI-E Bifurcation too enable 2x SSD's on the G1 Sniper M5 2nd PCIe slot for 8x lanes. My 16x 1st slot is occupied by a gtx 780 :D

[dimagass]

My laptop is a joke but I got a 970 evo plus and upgraded from the 258 gb edition to the 1tb edition

[uncrunch]

If you write and erase non stop on a new high endurance SSD at SATA 3 speed you'll kill it in 1 to 3 months. Going by their TBW rating.

i have evo 860. 250gb. bought since 2017. now its already 15TBW out of 75TBW claimed by samsung official website, and has 2 year, 6 month of power on.
its been 4 years i think. with simple calculation, my yearly usage is 3.75TBW per year. with 60TBW remaining left, i still have 16-20 years left before it reaches its peak. lol
