Ce SATA am ?!

[ESA1899]

Bună ziua! Dacă nu vă supărați.. dețin un laptop Dell E5430. Aș dori să îmi spuneți ce inferfață dețin (SATA I,II sau III). Unde pot să văd ce interfață dețin? M-am uitat în BIOS, dar nimic. Sper să mă ajutați voi. Cum influențează interfața un SSD ? Se poate schimba interfața? Vă mulțumesc frumos si aștept răspunsurile voastre!

Pe scurt si daca nu intelegi engleza: viteza e diferenta. Toate sunt compatibile intre ele, dar vor functiona la capacitatea maxima a portului. Daca ai un port SATA1, vei avea SATA 1 max speed. Daca ai SATA, poti pune orice hdd cu interfata SATA.

 

PS: Teoretic ai SATA II. Asa zice pe net (Serial ATA-300, up to 300MB/s).

Difference between SATA I, SATA II and SATA III

What is the difference between SATA I, SATA II and SATA III?

SATA I (revision 1.x) interface, formally known as SATA 1.5Gb/s, is the first generation SATA interface running at 1.5 Gb/s. The bandwidth throughput, which is supported by the interface, is up to 150MB/s.

SATA II (revision 2.x) interface, formally known as SATA 3Gb/s, is a second generation SATA interface running at 3.0 Gb/s. The bandwidth throughput, which is supported by the interface, is up to 300MB/s.

SATA III (revision 3.x) interface, formally known as SATA 6Gb/s, is a third generation SATA interface running at 6.0Gb/s. The bandwidth throughput, which is supported by the interface, is up to 600MB/s. This interface is backwards compatible with SATA 3 Gb/s interface.

SATA II specifications provide backward compatibility to function on SATA I ports. SATA III specifications provide backward compatibility to function on SATA I and SATA II ports. However, the maximum speed of the drive will be slower due to the lower speed limitations of the port.

Example: SanDisk Extreme SSD, which supports SATA 6Gb/s interface and when connected to SATA 6Gb/s port, can reach up to 550/520MB/s sequential read and sequential write speed rates respectively. However, when the drive is connected to SATA 3 Gb/s port, it can reach up to 285/275MB/s sequential read and sequential write speed rates respectively.
