SSD write speeds have reduced by half.

As the title suggests, my SSD writes speeds have reduced by half.

I initially got the SSD 2 months ago and ran Crystal Disk. I just ran it again today, and my write speeds for everything except sequential writes have dropped by 50%.

I have an Intel 310 mSATA. I have the newest RST drivers. 10.6.0.1002 (I was running 10.1.0.1022 but upgraded today).

When I initially ran the test, it was soon after I did a fresh install. Today my drive is 67% full (50GB out of 75GB used).

I have run fsutil to see if TRIM is enabled. I did that 2 months ago and it returned a 0 and I did it again today with the same result. So that shouldn't be the issue.

Can anyone shed some light here? Or give me an idea of how I can narrow down the problem?

Thanks in advance.

 

Wow dropped by half, so you're like getting about 40mb seq writes; here I thought the speed throttle issue was only a SandForce thing.

Are you sure you didn't change something in Windows or some setting in the SATA driver?

Can you run a CrystalMark bench and post up your snapshot results?

 

can you try to manual TRIM using the toolbox first ? A 67% full disk should not experience such a drop.

 

Here are the CDM Scores. First is from July 23, second is from Sept. 2.

I ran it a couple of time as well to double check, and this set of scores is actually the slightly better of the 2 (second time was 23 for 4K and 40 for 4K QD32).

I haven't changed any of the setting. How can I run a manual TRIM?

 

Install the Intel SSD toolbox, in there is an option to optimize or something like that, it is basically a manual TRIM.

 

Yeah, I had tried that. I assumed that's what it did (the description isn't too informative).

 

well, not much you can do then. So accept it as a 'deficiency' then.

 

Odd that the 320 is doing this, I thought only Sandforce degraded that badly at ~50%. My Vertex 2 certainly has slowed after 9 months, I'm pondering a reformat for it...but with all the trouble it gave me getting it working the first time, idk...

 

The 310 is not like the 320, it is basically a repackaged G2...haven't seen reports of those having severe degradation problems and they've been around awhile.

 

Though even at the reduced speed, it is still very fast. This applies to SF as well. The Q=32 is a scenario that is very unlikely to be seen in consumer oriented usage.

 

@ chimpanzee

Maybe the mSATA counter are actually a bit different from their full form brothers, different firmwares maybe?

At least I'm hoping for Paint Creek's sake.

 

Here is my 310 bought in May.

 

Wow, these results are quite shocking.

I was incredibly interested in getting an SSD but the price and issues that people are having deterred me from doing so.

I am sorry for your misfortunes with the declining write times. However, I do hope down the road the prices come down and these things become more stable.

 

Wait till the newer Intel mSATA's are released then contact Intel for RMA with the hopes they'll send you the newer revision. If not, you'll still get a new 310 that should not have the same problem.
