That it doesn't disappear under heavy load like the 850Pro does.
yes really :(
It was only a matter of time before Samsung dropped its 32-layer 3D V-NAND (3D Vertical NAND) technology further down the food chain, following its début in the high-end 850 PRO. The result is now with us in the shape of the 850 EVO, which, just like its 840 EVO predecessor, differs from the standard 850 PRO in the type of NAND …
It will if it writes jumbo frames faster than it reads them. According to that test software, it does. I don't know much about the inner workings of disk drives, but if you verify slower than you write, you have to slow everyone down.
Considering everyone uses jumbo frames today, this shouldn't be a problem *if* everyone uses them, suggesting the 64thrd test is correct. However, if 1 person spills the punch by writing 512... Of course using 512 might be faster (didn't read that info in the article).
Curious what is heavy load for you? I've been running 850 pro on my 4 year old laptop(SATA 2 only) since September and no issues. 99% of the time in linux, though I have booted to windows a few times. I wouldn't consider my workload heavy though I did notice that I was writing about 1TB/mo to the drive according to the samsung tools. Haven't checked in a month or so.
Too expensive for me really, I agree, but it's about £6 per month over the guaranteed lifespan - I guess there are some people who think they will get that much benefit.
It might potentially save 30 seconds on the daily boot time of a PC which would be 10 hours over that period if you are cold booting every week day.
Yes, I might be looking for justifications, however flimsy, for buying something that I want way more than I need.
Showing two machines.
Both identical except for the SSD in them.
One has say a Crucial M100 (a decent standard SSD) in it and the other whatever high flying top of the range SSD is out at the moment.
Then trigger the same tests/scenarios on both machines to see what the real world user experience is.
An SSD has got to be the single best upgrade spend I have ever made. Look out for deals though. I doubt most people need higher performance SSDs like the Samsung Pros. The biggest benefit to me is just eliminating the thrashing you invariably get under Windows and even the cheapest SSD improves that massively.
I had a OCZ refurb 100GB which I picked up for £40 a year or so ago. It was SATA II but made such a huge difference, I doubt I was ever near the max of the SATA II interface. Bought a new machine which came with a newer Kingston so the OCZ went into my lab.
Just buy one, any one.
"... If any more proof of the endurance of V-NAND is needed then a quick glance at the TBW (Total Bytes Written) for the 840 and 850 EVO’s is all you need. The 1TB 850 EVO has a TBW figure of 150TB (works out at 82GB/day), which eclipses the 72TB of the 1TB 840 EVO."
With 24GB or RAM and a laptop that hibernates at least 6-8 times per day, 82GB per day is not really a lot...
