Samsung 830 slow sequential read and write

post #1 of 27
Thread Starter 
So I just got a new Samsung 830 256GB and I transferred my OS over from my old Velociraptor RAID 0 array. Unfortunately, my speeds for sequential read and writes are slower than they should be. I used Sean's guide for settings up my OS and updated my firmware and chipset drivers, yet the performance has not changed.

What is going on?

Here are the results:

What SATA port is your SSD in? Intel 6GB? Might want to check that.

Here's my SS 830 SSD 64GB

Maybe check your power options too? uh...AHCI in bios?

I know it'd suck but if nothing else works..RMA...I'd hate to do that tho after installing everything...gosh what a pain:mad:

My motherboard only supports SATA 3GB. Sean said there wouldn't be much of a performance difference vs. SATA III.

I have AHCI enabled as I had RAID before.

When Sean said not much of a difference, he meant in the real world not in benchmarks.

Your drive is plenty fast for Sata 3gb/s.

But that is what is holding my drive back then? I mean I have definitely noticed the increase speed from my old RAID array.

More than likely the issue.

What do you mean holding you back? Sequential reads/writes are limited to the SATA 3GB/s though put limit...

In normal everyday use you will not I repeat, will not, notice the difference b/w SATA 3GB/s and SATA 6GB/s...maybe the only thing I noticed was that boot up time was 1 second faster...and games loaded slightly faster...slightly.

I´m not a practical expert in SSDs(hell, I'm nothing more than a theoretical expert...been reading SSDs test/datasheets/comparatives/posts&information for 3 years...been using a SSD for 2 weeks xD), but I think your Samsung 830 256gb is somewhat slowed down. Judging from your rig(Evga x58 with SataII conectors, ram-a-lot, cpu-a-lot, decent videocard) and the SSD you have, you are a bit below the full Sata II bandwidth specs. But something might be slowing down the Samsung SSD.

Have you tried a clean install? Maybe your OS is already configured for your "old" Velociraptor RAID array, and hasn't been tweaked to work with an SSD. From my experience, what works in one environment usually doesn't work in another different environment.
RAID enabled with something like RAID rom/drivers after Bios Post? Or just plain AHCI?Mmaybe a RAID config without two Samsung SSDs is slowing you down. From my experience with RAID0, the speed of one drive plus the speed of another doesn't equal 2x, more like 1,70x/1,80x.
Overprovisioned between 7%/11% of your SSD space?
Have you let your system idle for some hours?Samsung 830 SSDs controller uses idle time Garbage Collection/TRIM...meaning you could do a lot of reads and writes, what obviously diminishes your SSD performance, then let your system idle instead of powering it off for some hours, GC/TRIM starts...and then you have your Samsung SSD in top shape again.

PD: Samsung 470/830 SSDs, as of today, are the only high grade consumer SSDs without known firmware bugs/engineering mistakes. Intel had the 8mb bug that erased the whole SSD. Even Crucial M4's are having some sort of early death when they reach 5200 power-on hours, luckily next firmware fro Crucial is going to solve that issue. But as of today(I hope it remains the same over the time biggrin.gif), Samsung SSDs are the only SSDs without problems. Get a SATAIII 20$ pci-e card fro your rig and start kicking butts biggrin.gif

looks fine. Your never gonna get the full speed of the sata II spec but pretty close. I have the 64gb version and its pretty well on what you have, other then the slower write speed.
