Samsung Starts Shipping 4TB model of 850 Evo SSD

Samsung has started rolling out their 4TB version of their 850 Evo SSD. This 2.5" model appeared in online pricewatch engines and will be selling for 1349 euro. The high capacity is possible due to vertically stacked NAND.

Samsung earlier last year already announced that the 4TB model would be released in 2016. It is very likely we'll see a 4TB PRO model soon as well, the high-end model. Though that is not confirmed and this we do not know a price on that model either.

Back in August during the flash memory summit Samsung announced their 3rd gen V-nand technology, the new revision bumped the current 32-layers towards 48 layered stacks of NAND flash memory. The SATA III based 2.5" 850 pro and 850 EVO had been announced as the first SSDs in line to receive the NAND upgrade and thus larger capacities to 4TB.

Up-to now the maximum size was 2TB (read our 850 EVO 2TB review here).

Is Samsung smoking that funny stuff? You can buy 4 of the 1tb variants for less than that.

Don't think so.
First, today's largest Evo model, with 2Tb, is slightly more expensive than 2 x 1Tb, so one should expect some loss of economy of scale as we move to 4Tb.
Second, this is a premium product (waiting for Pro version, I'll give you that) so it will always carry a premium price.
Finally, you have TRIM issues, unless it was fixed for RAIDs.

If someone needs 4TB of storage, there is at least 3TB of garbage involved. That 3TB is static and won't be touched much. You better never turn off that system so the controller can keep moving that data around. If you think that data is safe you don't understand current NAND technology.

Why aren't they making storage SSDs yet? I mean slower nand, maybe around HDD speeds, which would be cheaper. I'm so ready to move to SSD storage, no more noise, vibration and moving parts please.

Manufacturers are too fixated on speed, I think there should be 2 kinds of SSDs, ultra fast ones for boot drivers, and slower, extremely power efficient ones for storage but with good price/GB ratio.

Doesn't work like that. Manufacturers aren't fixated on speed, they are fixated on NAND density. The more dense the NAND is, the faster it is, the cheaper it is, the more efficient it is.

Currently SSDs don't make great long-term storage drives due to leakage. That's probably why they aren't heavily marketing them towards storage.

Anyone remember this from the early 80's?

1349eu for 4tb SSD doesnt sound too bad after all.
