Show us your SSD performance 2

Here's my 1TB Samsung 480 EVO with rapid mode on. There seems to be a bit of variation between times I've run the test.



...

And here's CrystalDiskMark

840Pro 256GB, 10% for Over Provisioning, with Rapid Mode.
Wrend it may not affect it much but these benchmarks do a lot of read/write cycles. ASSSD and Crystal never agree on mine. I think it's because one uses compressed data and one doesn't.

Those are likely relevant factors too, but with the 840s, RAPID Mode probably has a lot to do with it. That is a feature of the Samsung SSD software that allows for caching of the SSD on RAM.

Seems the Samsung 840's are owning the SSD department in speed.. Out of curiosity, how much different would / could the drive controller make in these cases? Or would it be a simple case of SATA2 or SATA3?

I think the controller has a lot to do with the Sammie's speeds. It is a 3 core made in-house by Samsung so they control the whole thing including making their own NAND.

You'd not notice any difference from SATAII to SATAIII but benchmarks would. Either will perform the same, faster than greased lightning.
I don't know where the caching is for Rapid Mode, looking as Resource Monitor it does not show and RAM for it.

In RAM somewhere; I would imagine in used, but it might be in standby or similar, I suppose. It uses up to 1GB of your RAM, depending how much it deems you have available to use, and it will also free it up as needed.

More info on Samsung RAPID Mode here (interesting read, in my opinion): http://www.samsung.com/pl/business-i...pid-Mode-0.pdf

I'm wrong, again, there are entries for Samsung Rapid Mode in RAM.

I remember when I tried out primocache. I guess it's similar to Rapid mode on the Samsung drives.

I liked that too Paul until the trial run out.

Is it worth it to get an 840 for a SATA2 system? It could always be moved to a newer system later, but with the way prices and advancements are going, there will be a new Top Dog then. If SATA2 will not benefit, then a lower priced/rated SSD would do just as well. A Guy
