Pelo o que eu entendi, que não necessariamente vc precisará ter partição 333gb e a outra 666gb, como exemplo.
Acho que pode dividir em X tamanhos, e Y partições, mas que não seja superior a 333GB, ou 1/3 do "full-size" que é 1TB.
Mas para que o cache não fique FULL no TLC. E sim opere como MLC. Segue explicação técnica abaixo:
Modern TLC-based SSDs operate a portion of their flash in SLC mode to achieve higher rates for bursty loads, as writing in SLC mode is much faster than writing in TLC mode. While we typically see SLC caches in the 10 GB region, the SX6000 Pro takes a different route. Instead of SLC, the Realtek controller uses MLC mode, which is slower than SLC mode, but fast enough. The benefit is that MLC caching effectively doubles the size of the cache because it stores two bits per cell, while SLC stores only one bit. A somewhat surprising test result is that the SX6000 Pro will always write in MLC mode until the disk is completely full. Only then does it switch to TLC, which means it has to work extra hard then, moving existing data out of MLC into TLC to make space for incoming data while handling incoming read/write requests from the OS. As a result, when in that state, write performance is significantly reduced, down to around 200 MB/s. This can be a problem as it definitely affects the subjective user experience. Earlier TLC drives show similar speeds when flushing their SLC cache, too. Averaged, we see 500 MB/s sustained write, which is very decent—much better than QLC, better than most SATA drives, and comparable to earlier NVMe TLC SSDs.
Esse era o ponto que até levantei aqui no Adrena, DRAM ou DRAM-LESS, fazendo comparação ao preço, mas como não tive o reply, fui procurar.
Seguinte DRAM, tem o acesso/mapping mais rápido do que a memória-flash. E não ocupa RAM do Sistema.
o SX6000PRO, utiliza HMB de 64mb, que praticamente não usa RAM do sistema e usa como forma de suprir a falta da DRAM, e pelo que vi de forma bem eficiente.
Na real tanto o Crucial P1 (que acabei pagando 10% a mais) e o SX6000PRO são equivalentes. A minha decisão de compra de "pagar a mais" pelo P1. Foi por ser a marca Crucial/Micron e por
pensar no longo prazo uma "certa" assistência a Garantia e Firmware melhores, mas supondo. Hoje eu optaria pelo SX6000PRO pelo preço (seria quase R$100,00) de diferença.
O PNY CS3030 tem DRAM, é um NVME acima em performance dos citados. Mas não chega nos nível de WD BLACK e Samsungs 970. É um ótimo SSD, fique tranquilo. Acima da média.
Agora sobre o CS3030 PNY, aliás foi o que mais me agradou, quando comecei a procurar por NVME. Tenho um PNY CS2211 ainda no setup, que comprei em 2015, e achei um puta SSD.
Perdi uma baita promo do 500gb por R$370,00 no CS3030. Ai começou a inflacionar o preços dos SSD aqui, e não parou mais. Então tive que optar pelo P1 e o AData em questão.
Segue explicação sobre DRAM:
DRAM on an SSD is used as fast temporary storage for the drive's internal mapping tables, which translate between physical disk addresses (the OS sees) and the actual location of where the data is stored in the flash chips: "which chip, at which location". Using DRAM has a speed advantage as it operates much faster than flash, but it's a cost/performance trade-off. A 1 TB SSD typically uses 1 GB of DRAM, which costs a few dollars. If you can save that, you'll be able to position your drive more aggressively, leading to more sales, or you'll enjoy higher margins. Unlike most other DRAM-less drives, the ADATA SX6000 Pro uses the Host Memory Buffer feature of NVMe, which allocates a small portion of system memory for the SSD. In ADATA's case, the memory size is 64 MB, which is negligible if you consider the multi-gigabyte memory sizes of today's computers. As our testing shows, even this small amount of HMB can help with performance. Averaged over all our benchmarks, we see the SX6000 Pro compete with drives like the Crucial P1, WD Blue NVMe, Intel 760p, and Samsung 950 Pro, which are all within a few percentages of each other. More expensive NVMe drives reach around 8% higher average performance, which is not a lot, especially when you factor in how affordable the SX6000 Pro is.
Aliás vou deixar para quem quiser ver o melhor, e mais completo, review do SX6000PRO:
Priced at a stunning $110, the ADATA SX6000 Pro 1 TB is one of the most affordable NVMe drives on the market, and a heatsink is included, too, to help avoid thermal throttling. In our performance testing, we see decent performance that's within a few percentages of other, more expensive M.2 SSDs.
