This is a great forum which I liked the nice answers too.

I really believed my mobo had sata 3 i seriously believed that the box said it too,but the box is gone .and it so happens that it doesnt according to the machine (unless there is a way to find out i dont know about).

And with the other SSD hard drives at the store costing about the same price and almost no way I can return this hard drive.

I have a phew questions.

If I buy a sata 3 pci-e card, Will it run at its full speed?(and run at its full potential)

How to set up the 850 Evo to its full potential to a sata 2?(I see alot of settings but would like to know more from a person that knows more about stuff than me or has more experience with this topic)

Thanks for your time.

You can't make a sata II port go any faster then sataII speeds. But sata II is still fast and a sata III drive will work in a sata II port

And yes a pci e sata III card should give you full speed

I am asking because here on the settings it says lower the speed of the read/write and boost something else, since its not gonna go at full speed anyways can I lower it and keep the read/write speed while still boosting the other thing

knowing your System Specs Might help someone help You, i recommend that You take the time to fill them, Even if it wont help with This issue, it is still a useful step to take.

wha?

Your are limited by the port. There isn't any tweaking involved.

A while ago I upgraded my dad his socket 775 system with an SSD, the motherboard only supports SATA II,
the SSD won't run at full speed, yet it's far better than before with HDD, faster response/access times.

You might not reach the theoretical maximum read/write speeds, but it should perform the same. Unless copying files from this drive to another one (or though a network faster than gigabit LAN) is a concern for you, it's not worth worrying about. The beauty of SSD drives lies in access times and random read/write speed, which will be fine even on SATA-II.

SSD's aren't fast because of their throughput, they are fast because of nonexistant seek times and IOPS out of the wazoo.

MB/s is all nice and dandy, but every time the head of your platter disk has to move to look for a file and wait for the disk itself to complete a spin, your CPU is doing an infinity of nothing.

To put in perspective: a 12ms seek time on a platter disk translates to 192.000.000 wasted cycles on a 4Ghz quadcore cpu.

I am not aware of any way how a SATAII interface would inhibit an SSD when it comes to seek times. The only difference would be throughput and burst speeds. Load times might be slightly higher than a SATAIII interface, but general snappiness and responsivity of the system will be (nearly) identical.

Either way, a huge upgrade for any system.

I should really have bought stock in Crucial or something, at least that way I wouldn't be an unpaid shill :rolleyes:

Benchmark Scores Don't know any benchmark. It runs good enough for me.
Even a sata 2 with an ssd is huge performance boost. I use an ssd with a 2007 core duo laptop. Not even a core 2 duo. The boot time for that old laptop is 15 seconds on a sata 2. Programs open very quickly despite the cpu being an old one. An ssd would be a massive boost from HDD even if the sequential speed is at sata 2. Highly impressive. Sata 2 would not bottleneck the important ssd speed the random read and writes. Random read for ssd is at about 30MB/s which a sata 2 could still provide. Now compare that with a Hdd random read at 0.7MB/s, you will feel the huge speed increase

Feel I should point out that putting a PCIe SATA III controller card onto your motherboard will not automatically give you SATA III speeds.

Have to make sure said controller card is on a PCIe x4 slot to gain the "theoretical" speeds of SATA III, and also that said card is also a PCIe x4 version (they do exist).

So true, i have a old DELL 1764 ( 2010 ) and it loads like if the laptop was brought yesterday and that's even with a old sata2 ssd. Would not be much difference ( if any ) if it was a sata3 ssd.

just run it on SATA II until you replace the PC/get a new motherboard.

It wont be at its full potential, but its still going to be damned fast.

I think, if you haven't already determined, you should just go ahead and bring the EVO back. You'll lose a little money due to restocking fees or whatever, you could also E-bay it.

Just stick with the HDD for a while. That way, you won't have to worry so much. SSD's are so fast!! You don't want to constantly be wishing you weren't bottlenecking your SSD!!

I had an AM3 motherboard that had SATA II ports Bought an SATA III SSD for it and was still very impressed how fast it was. Eventually bought an AM3+ motherboard with SATA III ports and moved the SSD over to it. I couldn't tell any difference in speed while just doing task like browsing or gaming or start up or shut down. Basically OP, just go with it. You'll be happy.

most of the benefits are simply because the SSD still gives you the latency improvements, even if you were on SATA1.

Sata 2 or 3 don't matter. You won't see any difference in every day usage. It's the near zero seek time that makes SSD a wonderful thing.

Now, if you want to benchmark it and epeen it, then ... it will pose (serious) issues.

You know I got intel sata II and marvel sata III control on my mother board and the intel performed better than the marvel in raid 0 SSD evos

thats just because the secondary controllers on boards are always bandwidth starved.

Yea when I found this out I googled the marvel controller to see what the deal was and I was not alone in the countless people that said it was junk and would rather use the intel.
