E já aí temos o vertical NAND no mercado. :Festa:

Those are two sequential runs after fragmentation, *without TRIM*. The low-level changes Samsung has made to this V-NAND flash make it nearly immune to typical 4k random accesses in absence of TRIM (our fragmentation efforts prior to these passes have a small amount of <4k IO sprinkled in). I have never seen any SSD so apparently resilient against fragmentation.




Update (7/1/2014 @ 2:45AM EDT): Already, Samsung has updated their MSRP listings:
128GB - $129.99 USD ($1.02/GB)
256GB - $199.99 USD ($0.78/GB)
512GB - $399.99 USD ($0.78/GB)
1TB - $699.99 USD ($0.68/GB)

Warranty and Availability:
I wasn't kidding earlier. Samsung has so much confidence in the increased endurance of their V-NAND that they've upped the warranty to 10-years, rated at 40GB of writes per day, which equates to 150TB of total writes. The drives will be available for purchase on July 21st.

Final Thoughts:
The Samsung 850 PRO delivers on one of the potential answers to ever more difficult flash memory die shrinks. Instead of shrinking, Samsung actually expanded their process back up to 30nm and chose to go vertical! They plugged this new V-NAND into their existing controller technology and really made it sing. The structure and interface improvements of this new flash also go a long way to alleviate some of the small write speed issues seen on typical 2D NAND, making it very resilient to fragmentation over time, which should help out in RAID configurations lacking TRIM support. Overall I'm extremely impressed with the 850 PRO. The only fault I can really find is that intro pricing is a tad high, but to that I say here's hoping we seen an 850 EVO soon!


Preços um pouco acima, mas é apenas o começo. Os futuros que saírem com novo controlador e a tech mais desenvolvida já deverão ser mais acessíveis. De qualquer forma, 10 anos de garantia! :O Tomara eu nos meus HDD. :[

Este ano está a ser bastante bom para os SSDs.
Entre os preços a baixarem consideravelmente e estes avanços, há cada vez mais motivos para ter um SSD.

Por enquanto ainda me fico pelo meu Intel 330, mas já começo a pensar num upgrade. Mais pelo espaço extra, do que pelo desempenho.

Boas!
Sem dúvida, este ano está a ser o ano dos SSD´s...

Já existem alternativas bem baratas e boas...
Eu para já ainda ando com o meu Samsung 840 de 512gb...

Apesar de ser TLC e mais lento e bla bla bla...

Não se nota nada no dia a dia... Alias o meu agility 3 tb era supostamente lento (em especial nos I/OPs) e nunca notei nada no dia a dia...
Tudo carrega-se extremamente rápido e sem delays...

Quando trocar é para meter um SSD de 1TB, antes disso não me vejo a trocar o SSD...

No entanto este ano vamos ver boas evoluções...

- Melhor preço por GB
- Melhores controladores e memórias
- SSD´s para M.2 e SATA-E

Cumprimentos,

LPC
