Is this SSD properly support SATA II?

This SSD came with a Latitude D630 which was super cheap, and I honestly only got it for the SSD since the drive is worth about as much if not more then the computer - it’s a common spec D630, so the SSD made up for that. However, my concern is if the SSD it came with is SATA II ready, as the D630 is notoriously known for not supporting SATA III support due to the chipset (i965GM or 965PM). It seems to be fine, but I also didn’t run it much because I need to find a keyboard.

Is this SSD support SATA II, or should I just put this in a more suited machine and buy a SSD that’s better for the D630? It is an SDSDSA-240G as far as I can tell. It doesn’t look like it does, but I also can’t find any positive proof either.

@nick - Sadly it won’t play nice in your SATA II (3.0 Gb/s) system as its a fixed SATA III (6.0 Gb/s). You’ll need to find an older drive (Fixed) or get one of the Auto Sense drives.

Yeah that's what I was afraid of :(. Dell didn't support SATA III with a solid yes on the Latitude until the E6X20 - same point on the E5. The E6X10 remains a question to this day as well, but I work under the SATA II assumption pre Sandy (5/6X20) there.

Now combine that issue with this being a D series and this is new enough to shed the SATA I question mark, it's a matter of checking for SATA II support - I don't need SATA I since I run in AHCI. Like come on... The seller knew this is old enough to KNOW it's a bit of a question, yet put it in.

The reason I was making sure is because I wanted to try and avoid the unreliability issue these Fixed III drives are known for knowing this SATA I/II only.

SATA 3 drives will work on SATA 2 but will you will lose a lot of the drive’s performance. You should still see an improvement over a traditional hard drive though :)

Ah! The old issue of upper or downwardly compatible!

SATA I (1.5 Gb/s) drives will work in any system which offers a SATA I (1.5 Gb/s), SATA II (3.0 Gb/s) or SATA III (6.0 Gb/s) connection. Likewise, a SATA II drive will also work in either a SATA I (1.5 Gb/s) or SATA II (3.0 Gb/s) system. Lastly, a SATA III (6.0 Gb/s) drive will only work correctly in a SATA III (6.0 Gb/s) based system.

Here we are only talking about drives which are fixed. Think of it like a bike which doesn't offer any gears just the direct drive of one gear. This is how the standard is written. Back in the day the cost of the drives where quite expensive besides wanting the data on them! So it was assumed people would bring their expensive drives to their newer system as the standards improved.

There is another type of drive! We call it an Auto Sensing Drive these drives have additional logic which allow it to sense the systems SATA Port's I/O data rate and then match it! So with these drives you can slide them into any system!

Now the rub! You need to review the given drives spec sheet to discover if its Fixed or Auto Sense type of drive. If the spec sheet for the drive lists one SATA speed then it's Fixed! If it states clearly multiple SATA speeds its Auto Sense As an example this SSD is Auto Sense Samsung 870 EVO Note the Interface states "SATA 6 Gb/s Interface, compatible with SATA 3 Gb/s & 1.5 interfaces" Many drive makers have dropped Auto Sense technology to be more competitive as most systems are now SATA III based as an example this drive used to be Auto Sense now its Fixed!

Seagate FireCuda - Auto Sense Before they renamed it.

Seagate FireCuda - Fixed

For both 2.5" and 3.5" drives! So you need to make sure the drive you get the correct rev now as well.


Perfect Explanation @danj great detail too...
