Kingston V310 superb endurance for a consumer SSD?

[SSBrain]

Hi folks,

I wonder if anybody noticed Kingston's press release about their new V310 SSD.

http://www.kingston.com/us/company/press/article/7297

The real news here, besides this one being one of the very few SSDs with a Phison controller, is that the (declared) endurance specification is incredibly high for a consumer SSD :

Total Bytes Written (TBW): 2728TB 2.56DWPD

That's, in case it wasn't clear enough, 2728 terabytes written, 2.56 drive writes per day when most SSD manufacturers won't dare saying their drives will last more than 80 TBW, and apparently with standard 128Gb Micron MLC NAND!

Will this change the way other manufacturers will approach this most often artificially deflated figure? I hope it does. Time will tell.

I wouldn't care if this thing offered free booze and babes as fringe benefits. After Kingston screwed people around with the V300 (including me), they are off my list of possible sources for SSD's or memory. Won't recommend them and won't buy from them.

I had one Kingston and returned it the same day. Was years ago. I went for the Crucial C300 and later for Samsung 830 then 840 PRO and EVO.
This is all I have to say about Kingston...bait-and-switch...urgs.

TBH, they probably just left out a decimal point.

Maybe they're trying to redeem themselves from the V300 NAND change fiasco?

TBH, they probably just left out a decimal point.

If you take into account 1024 GiB of physically available NAND memory, that's 1024 GiB * 2.56 drive writes per day * 365 days * 3 years = 2,870,476.8 GiB = 2,803.2 TiB, so the calculation is consistent with the data. This is also consistent with 3000 P/E cycles MLC NAND memory being used with a sequential workload write amplification taken into account (close to 1.0x). I don't think it's a typo.

Anyway, as I've written previously here and on different venues, what matters here is how other manufacturers will respond to this since they usually keep the write endurance figure artificially low to not cannibalize their enterprise SSD line up. It looks like Kingston is going to break their "gentlemen's agreement".

Micron/Crucial, OTOH, uses a random/sequential mix, that is at ;east loosely defined in their documentation (probably others, too, but I've actually gone and read theirs ). It would be nice if they increased the value for larger drives, but the 72TB for ~120GB isn't just sequential, which would be unrealistic.
