SandForce TRIM Issue & Corsair Force Series GS (240GB) Review
by Kristian Vättö on November 22, 2012 1:00 PM ESTPower Consumption
Power consumption is pretty standard SandForce. Idle power consumption has always been fairly high but load power consumption is about average, unless you're writing incompressible data which increases power consumption significantly.

One question, all of the tests at Anandtech for Sandforce performance after being hammered for a period of time are always over the entire drive. Do the drives maintain their performance if the random writes are only over 50% or 75% of the LBA's on the drive? Very few people actually fill up their SSD so I wonder if it is a truely relevant test?Impulses - Wednesday, November 28, 2012 - link
You will always eventually use all of your SSD, wear leveling algorithms will spread data across all NAND packages... A certain portion will always be marked "empty" if you haven't filled it to capacity, but that space has been issued and it's subject to the performance degradation conditions AT tests for.Bullwinkle J Moose - Thursday, November 22, 2012 - link
Time for an article on Cache Analysis?It looks to me as though the 1GB Dram Cache on the Intel DC S3700 is mainly responsible for smoothing out those peaks and valleys to deliver "Consistant" performance across the drive
As for trim.....
It's time to start with a fresh perspective on SSD's

I know Intel claimed otherwise on the dram usage, but I don't buy itSounds more likely they are just sending the competition on a wild goose chase

Reread DC S3700 review again256MB of the 1GB is used for cache
OK, my bad

DohIf I read it 5 more times I'll get it right eventually

If it were that easy, don't you think other guys would have drives like the 3700 out?Kristian Vättö - Friday, November 23, 2012 - link
The problem with caching in general is that there is no good way to test how much write/read caching the drive is doing. All we got is what manufacturers tell us, which may or may not be accurate.mayankleoboy1 - Friday, November 23, 2012 - link
With each review, Samsung 840Pro looks better and better.JellyRoll - Friday, November 23, 2012 - link
This information has been already hashed over by several sites, in particular TweakTown. They have been educating the public for months about the lack of TRIM with Sandforce SSDs.Other sites have also noticed the read degradation, and commented on it ad nauseum.
