mdforlifehon :
Can anyone help me with the connection standards for upgrading my 10+ YO Optiplex 755 DT for SSD's. I mean it only says SATA, not I, II or III. I assume its SATA I. Please let me know about the interface cables and or slots and width of the SSD drive. 250GB +/- 50GB is what I want my SSD to be. Any help would be supremely appreciated. Thanks. mdforlifehon at gmail dot com
SATA I, II, III are forwards and backwards compatible.
Of course, it only runs at the speed of the slowest device in the chain.
A brand new SATA III SSD connected to a SATA I port will only run at SATA I speed.
Similarly, a SATA II SSD connected to a SATA III port will only produce SATA II speed.
SO connecting a 2.5" SATA drive to that system may not bring any real benefit.
Another consideration is the OS. AN older OS (XP perhaps), does not know how to talk to an SSD. Primarily the TRIM function.
The drive will work no problem, but the older OS's don't know how to keep it functioning properly.
Why are you looking for an SSD in this old system?
