[SOLVED] SSD not in FULL SPEED

[autoblogart]

I just got a KINGSTON A400 240GB SSD Yesterday and installed windows on it , but im surprised that im not getting the full speed , only half speed wich is 235mb/s reading and 220mb/s writing , It's Supposed to be 450mb/s - 500mb/s as mentioned from the company

- SPACE USED OF THE SSD : 31Gb out of 240gb


My SPECS :

DELL OPTIPLEX 390 DT Motherboard
Intel core i5-2500K 3.3Ghz ( NOT overclocked )
4GB x 2 Slots = 8GB RAM DDR3 1066Mhz
Nvidia GTX 650 1GB GDDR5 ( With Latest Drivers )
WINDOWS 10 PRO Version 1803 OS Build 17134.1



Do You have any idea please ?

I hope that everything is clear , if not please don't hesitate to ask me i will reply asap

Thank you in Advance .

Uhm......you're pretty-much right in the expected performance zone for a Kingston SSD:

Actually i have just did a benchmark and i did find out that its much more lower than the values i did provide

I don't think your motherboard's chipset support SATA III. It is probably mitigated to SATA II speed

The specs I see on your mainboard shows SATA2 specs, which will be half speed compared to SATA3.....

Half of 550 MB/sec peak sequential SATA3 spec, best case, is....about 275 MB/sec?

Yes if that's in fact working as SATA II you can expect half the bandwidth.

Also that SSD also being the system drive (where Windows lives) doesn't help benchmarking speeds either.

Yep - NOT Sata 3
