Power Consumption
We reported drive only power consumption in three scenarios: idle, during sequential writes and during high queue depth 4KB random writes. At idle the V+100 does incredibly well, but under load it is one of the most power hungry SSDs we've tested. As bad as that sounds we're still talking about half of the power usage of a 600GB VelociRaptor, but in a notebook don't expect to save any power under load - only at idle.
A big contributing factor to the high power usage is the controller's aggressive garbage collection. To be fair however, even the SandForce drives require similar power levels if faced with incompressible data.

"check the speed without compression and then compare drives "That makes no sense!
It's like saying disable branch predictions on one processor because another doesn't have it. Or disable the turbo on one car when comparing to a competing car that is naturally aspirated.

It makes all the sense because it would be a fair comparison of all the SSD's availableNot all drives have compression and not all data is compressible so why not test them all without compression?
Are you afraid that OCZ would be at the bottom of the list in a fair test like this?
Well, you may be right!
Lets test them to be sure

I'm not an expert on SSDs and RAID. So excuse me if my question is a bit stupid.I always understood that it´s impossible to use TRIM with a RAID configuration because the RAID controllers can't ´pass' the TRIM commands. So the SSD performance would drop overtime when using RAID. Now the SSD controller has "always-on garbage collection". Does this mean the performance in a RAID configuration doesn't drop?

I would think so, it would at least be better off than other drive with less aggressive garbage collection.sparky76 - Thursday, November 11, 2010 - link
Will controllers like this leave OS X with a performance advantage over Windows 7, precisely because OS X has no support for the TRIM command?It seems that Win7 will have some system overhead in running TRIM while any OS without TRIM support will not suffer this, as garbage collection will be left to the firmware in the drive.

I would love to see loading and minimum frame rate tests from actual games like what was done here a while back.http://www.anandtech.com/show/2614/14
It's just really hard to visualize real world performance even from Vantage.
I would bet a game like Fallout 3 would benefit a lot in the minimum frame rate department since it's always loading new data from the hard drive.

I second this. While the IOPS for Bench are a nice measure, I don't know how to actually translate that into real world performance differences. I.e. are the differences in IOPS between say the new Kingston drive and Sandforce drives actually noticeable, and if yes, how noticeable?I would like to see a review that shows how much faster a Sandforce drive is than my old Vertex 1 and X25-M G2.

I'd also like to see that, as I said before.Just look at this test from (german) CB as an example:

Huge differences in synthetic tests, but a normal desktop system is just too slow to actually benefit from this!
I'm also missing these kinds of tests here. I think your earlier tests were better - now you just go through synthetic tests and show us the results, this isn't the thing I expected 1 or 2 years ago from an SSD test from anandtech.com. I'd like to see more tests which actually measure performance a user really gets when doing everyday tasks.

Wouldn't it be better to have a drive-based sort function run to test how responsive the drive is? I would guess it would stress all of the corners of SSD performance. Write a bunch, shuffle in small portions when flipping values. Maybe it wouldn't test sequential erase. I still think it would show great info.Sufo - Thursday, November 11, 2010 - link
Just a quick recommendation. I have one of these, and i can confirm that with windows 7 (ie TRIM) and a 6gbps bridge the performance is pretty delicious. Grab one, if you meet these requirements.
