It is now down to two drives at The Tech Report, only the Samsung 840 Pro and a HyperX 3K which was brought in to replace an model with no stamina have reached the 2 petabyte mark and are still going. The 840 Pro has now used 61% of its used block reserve due to flash failures and while the Sandforce compression has allowed the HyperX to hit this mark with only 1.4 petabytes actually written it has still had 31 sectors reallocated and 2 uncorrectible errors. That puts the HyperX in a difficult spot in that while it is still writing data it is not truly trustworthy anymore. The drive speeds have remained remarkably consistent though the 840 is slowing down somewhat over time, check out the actual benchmark results in the latest update to The Tech Report's torture test.
"Our SSD Endurance Experiment has reached an astounding two petabytes of writes. Only two drives remain, and they're coping very differently. We've checked in on their health and performance to see how each one is holding up."

Freaking amazing. I’m glad I
Freaking amazing. I’m glad I bought 2x Samsung 840 Pro 256GB for my Raid 0. In about 4000h just 6TB writes, this babys will last me a loooong time. Oh and no reallocated sectors or any errors so far.
I.N.S.A.N.E.

I’m glad i bought a Kingston
I’m glad i bought a Kingston hyperX 3k 240gb SSD, which is only $140cad. An the current price of the Samsung 840 PRO 256GB is $249cad.
I still cannot believe it’s
I still cannot believe it’s the friggin’ SandForce. Just…WHAT.
I will admit the 2 PetaByte
I will admit the 2 PetaByte being exceeded sure puts things in perspective.
even with 100Mbs internet connection, and downloading non-stop at maximum speed, it would look as following (rought estimates
100Mbs = 12.5MB/s
12.5MB/s ~= 1.03TB/day
1.03TB/day ~= 375.95TB/year
375.95TB/year ~= 5 years 4 months of continous writes
That is simply IMPRESSIVE.
For PCPer with Fiber at ~ 1Gbs.. we are talking a bit faster, at about 6 months 😉 You guys should try that 🙂
… and I don’t know if we
… and I don’t know if we would have long enough to see the Samsung 850 Pro die under such a test and I’ve just seen the the 512GB 850 going for $349 at Frys. I think you’ll have a Merry Christmas with a 512GB 840 Pro at Newegg now for $289 anyhow.
All that praise for Samsung, but I will tell you that I also have not had a Kingston product disappoint me either.
Great time for a new SSD ….
i just got a 1tb 850 pro up
i just got a 1tb 850 pro up and running in my rig (switched from a 1tb 840 evo) and i can tell you first hand you won’t regret your purchase. ^_^
Isn’t the 1TB Samsung’s SSD
Isn’t the 1TB Samsung’s SSD in particular is on SLC instead of MLC? If I remember it correctly, SLC has much shorter lifespan than that of MLC or TLC. They basically compromised the lifespan and reliability in stead of providing much bigger capacity for lesser price.
In fact the situation is
In fact the situation is quite the opposite, SLC has a much longer lifespan and costs two hells worth more, which is why you mainly only see it in enterprise drives (and even less and less there as they manage to pull more out of MLC). It’s SLC > MLC > TLC from the endurance viewpoint.
