New budget SSD - Samsung 750 EVO

[Coup27]

I think Magician 4.9 has let the cat out the bag there's another drive on it's way. It lists a 750 EVO as a model number in certain tabs. A quick Google finds this:

Looks like Samsung are trying to completely take over the consumer market and the only area they're not currently competing is the entry level / cheap as chips drives. According to Magician it still supports the same encryption levels as the mainstream drives which is surprising.

Do Samsung really need this?

If they can sell it for 10-15% less than the 850 EVO, and if it matches or beats the BX200 performance-wise, they'll basically wtfpwn everybody.

Do they need it? No. But if they can turn a profit on something like that, they'll clean up.

Really hoping this turns out to be great, I've been looking for a 250GB SSD for a laptop and the current pricing is slightly too high to justify it. Suspect there's a fair number of other people out there waiting for the 250/500gb drives to drop a bit more before jumping on them. And the BX200 is such a mediocre performer that they shouldn't have any trouble beating it.

The risk would be not separating it enough from the 850 either price or performance wise. If it was BX100 levels of performance (or even a bit less) at a decently lower price it'd likely massacre the budget segment and that's exactly what we need to bring the prices down some more.

Edit: Has been out in Japan for a month already? Link

I picked up one today, Model MZ-750120BW about 25% chaeaper than a 850EVO of the same capacity

What did they skimp out on to bring price down?

Endurance/warranty appears to be the biggest sufferer

3 Year Limited Warranty or 35 TBW Limited Warranty

For the 250gb version.

From what I can see it's already out but exclusively for the Japanese market, which is a bit random. Also uses planar TLC NAND which is surprising given the 840 and 840 EVO issues with that.

Maybe Kristian can shed some light?

Well, I hope they found a way to fix the 840 series planar TLC NAND problems that popped up after time.

For the time being I'd feel better buying an 850 EVO and its much more resilient and robust 3D NAND if the choice is available.

 

[Ranulf]

If it uses TLC NAND... no thanks.

That's how I feel. Samsung doesn't have a good record with planar TLC drives. (840, 840 EVO). One drive didn't even get fixes, and the other drive got a fix, that moves data around constantly and wears it out.

Actually, yes, they need to do this, but, the main reason is so they can get OEM wins in laptops. Anything else that may come there way, they won't complain.

Right now, toshiba SSDs have been the main player.

That's probably how the 750 EVO works - they "fixed" it by having firmware that constantly rewrites old data every few weeks by default like a "patched" 840 EVO. Quite honestly, I think the new "low end" SSD's are starting to get a little bit too low end. If the purpose of these is to say "Look at these prices, HDD's will soon be dead!", LOL, I won't be using any sub 40nm TLC for anything serious let alone "replace" an external backup HDD that sits unpowered 99.8% of the time with one even if they managed parity GB/$ vs HDD's...

I'm not sure if there's much I can publicly say about it. It's based on the same MGX controller that is found inside some 850 EVO models, but uses planar TLC NAND instead of V-NAND.

Currently the 750 EVO only available in select Asian countries. The Asian market is generally more price sensitive and there are numerous Chinese manufacturers, making the price war even more fierce.

They just want more bits, don't care if it's 1 or 0

Isn't that the same inferior controller that they used for the 840 EVO? Doesn't it lack support for advanced LDPECC or whatever the new type of ECC that the newer competing controllers use with TLC due to its inherent un-reliability?

The MGX is a newer generation, 840 EVO used MEX controller. I can't share anything about the underlying ECC technology, though. What I can say is that there were no reports of data loss or corruption in the 840 EVO, which would be the result of an insufficient ECC engine.

What sizes does the 750 come in?

120GB and 250GB.

For budget SSDs, I think these Team Group Ultra L5 have great specs:

http://www.newegg.com/Product/Product.aspx?Item=N82E16820313575 (120GB, $39.99 shipped)

http://www.newegg.com/Product/Product.aspx?Item=N82E16820313576 (240GB, $59.99 shipped)

I bought the 120GB one and upon disassembly found:

SM2246EN controller
Samsung DRAM
Sk Hynix NAND (according to the Team Group website it is synchronous MLC NAND )

Do the 750s use TLC NAND?

 

[Coup27]

Yes. Answered on post 15.

 

[Puffnstuff]

It kind of smacks of a revived 840.

 

[Coup27]

Well it is. More of a refreshed 840 EVO than an 840. The f/w will likely keep moving data around to keep it fresh so to avoid the slow down. It doesn't sound great to us but it's probably still better than what it's competing against in the target markets.
