mais uma ótima aquisição da marca KOOTION , produtos de qualidade que chegou muito bem e respondeu a altura.
Utilizei para colocar no meu XBOX ONE FAT , como armazenamento principal interno. Cumpriu sua função com qualidade e liberou desempenho para o antigo XBOX ONE FAT. Combinado com outro SSD de 2tb no USB 3.0 .
infelizmente o XBOX ONE FAT possui um barramento SATA2 o que limita a largura de banda do SSD que poderia chegar a 600mb de leitura , acaba sendo limitado a 300mb, entretanto, mesmo assim representa um desempenho MUITO superior a qualquer HDD mecânico, valendo a pena realizar a substituição.
Entretanto utilizar o SSD com um adaptador USB de forma externa , consegue utilizar mais do potencial do SSD pois a largura de banda do UBS3.0 é de até 500mb de leitura e escrita comparados ao SATA2 que é de 300mb.

Excelente SSD! Tenho só 6 da marca. Todos funcionando. Depois que conheci a Kootion, nunca mais quis saber da Kingston. Testado e aprovado.

SSD excelente! Entrega super rápida e o produto veio muito bem embalado, lacrado e em perfeito estado. Instalado no PC, ele reconheceu na hora e a velocidade de leitura e gravação é absurda — o sistema e os jogos abrem em segundos, mudou da água para o vinho. Ótimo custo-benefício para quem quer dar aquela acelerada na máquina. Recomendo demais o vendedor e o produto!

I ran tests with CrystalDiskMark and it reached 279 MB/s read speed and 257 MB/s write speed. My PC is limited to SATA II, so the SSD can't reach the speed limit of SATA III, but it still was very fast in daily use. In CrystalDiskInfo, it appeared with 100% health, only 5 power cycles and 31. ° C, showing that it is functioning normally. I transferred my Windows from the hard drive to it, and the speed difference was huge. For the small amount of 315 reais, I really liked it and I'm recommending it now to see if it will last a long time. It's another 500, but I already expected that by now. 🙏 👍

Já tô fazendo o clone da minha outra partição (HD) para o SSD. Já tenho um m.2 dessa marca a 2 anos e não decepcionou. O sata também parece bom. Nos testes que fiz, passou tudo certinho.
