I finely received my Samsung 830 SSD 256GB and I know it's been a year since AnandTech reviewed the Samsung 830 Series SSD 512GB version, has the real-time garbage collection improve much in a years time regarding firmware updates?

It's my understanding that when Anandtech reviewed the Samsung 830 SSD that real-time garbage collection needed much improvement, my decision to buy this SSD was because of the 95 percent of reviews that I did read before purchasing, Anandtech was the one that I missed.

Also would running two of these in RAID 0 improve SSD performance in real world and perhaps delay performance drops?



Performance Over Time & TRIM
Quote:
There's a significant drop in performance but the drive is still able to deliver ~100MB/s speeds. This graph is a bit deceptive however. After 20 minutes of 4KB random writes the SSD 830 will only write at a rate of around 20MB/s. By not doing much realtime garbage collection the random write speed can drop significantly over time, but at a lower write speed the 830 isn't penalized as much as other drives.
Quote:
Performance drops significantly, down to as low as 50MB/s for the earliest LBAs. Given enough idle time the 830 should correct much of this and obviously TRIMing those LBAs will restore full performance (as you'll see below) but the point is that by delaying the bulk of garbage collection the Samsung SSD 830 is able to drop in performance by a degree that I'm not super comfortable with.

I manually run TRIM now every day at midnight. I can't stand that performance loss. You can really see it on the boot time.

How do you run TRIM manually? I would like to do that too

This.

Run Samsung SSD Magician and select the Performance Optimization tab and select your SSD and run it. It automatically runs the Benchmark for it afterwards, but I normally just stop it because I don't like the excessive read/writes it does to your drive.

You will have lesser speeds and a lesser lifespan possibly as well. How are you checking if your alignment is good or not? Post screenshots of AS SSD.
