Hi guys,
Looking for some pointers here. Installed my spare SSD on a caddy tray - meant for the DVD/ Blue Ray slot.
When running the Samsung Magician Software, it is showing as SATA 3 is available.

Interface:
SATA 2 (3GB/s)
SATA 3 is available

Seriously, royally confused.
Does that mean that the DVD/ Blue Ray slot is actually a SATA 3 slot?
But then, the caddy tray is running on SATA2?
Then, i need to replace the caddy tray to SATA 3?
Looking forward to your feedback.

Samsung 870 EVO can support all SATA 1,2 and 3 speed.

How is the ssd connected to the motherboard? is it directly via a sata cable from the SSD into one of the mobo's sata slots?
what mobo is it and check the manufacturer spec if the sata slot you connected is SATA 3.

The SSD is connected via caddy tray - meant for the original DVD / Blu Ray slot.
This is a spare SSD.

sata for optical drive usually capped at at most sata 2

if software says sata 3 available is means that motherboard controller support sata 3

but the port for optical drive is different from the port for HDD/SSD. use slimline protocol which most laptop makers will capped at sata 2 because none of optical drive can make use of that speed


the problem is that slimline port bottleneck the speed. no other workarounds sadly

Too bad and you won't be able to fully utilise the speed of your SSD as the port connected to it has been capped by the manufacturer. You can log in into BIOS and check if it capable to allow you uncapped it or not.

By the way, this topic should be posted in Hardware section.

your system is a laptop or desktop?

check the motherboard spec and see if the sata connections are sata 2 or 3.

I believe you're using Samsung 870 Evo SATA SSD 2.5". If yes, you don't have to border about SATA 2 or SATA 3 because your 2.5" Samsung 870 Evo SATA SSD is max speed of 560 MB/s and SATA 2 is capable of supporting speed up to 3 GB/s. Your Samsung 870 Evo SATA SSD is currently running around 20% of the max speed of SATA 2.

dont confused GB vs Gb
SATA II is a second generation SATA interface, and it runs at 3.0 Gb/s
that is 375MB/s in the best case scenario..
