Yes and no. You will lose some Transfer rate speed. However the data rate will still be better and the access time is a huge benefit.
I have them hooked up to SATA 2 ports.
Here is a older Intel 320 Series SATA 2 SSD
And here is a 1Tb Seagate 7200 RPM drive
Notice the access time is 140 times worse in the regular drive vs the SSD. Then notice the transfer rate curve for the Seagate vs the Intel. The Intel is more or less flat.
The Access time and flat data curve are some of the Big advantages of a SSD along with the average data rate. And You do not ever need to defrag a SSD either.
To put it another way so what if You don't get the complete speed You still get a big boost in performance.
If I compare a Hyundai to a Ferrari on the roads of NJ. Would you not enjoy the Acceleration and handling of the Ferrari compared to the Hyundai even if they will both be capable of going the Speed Limit?
Think Hyundai = Regular Hard drive
vs SSD = the Ferrari
This may not apply to You but most SSD drives are SATA.
I hope this helps
