slowing ssd speeds

[dling]

What is the best way to regain speeds of slowing ssd? I did a speed test of my Crucial RealSSD C300 this morning and noticed that the speed were alot slower

then when I first got it. Its only 4 mths old. Very disappointing.

Were you working your SSD a lot during those 4 months? I guess I'll check when I get home to see how my C300's are doing. You can always back up your data or make an image, do a firmware update, and see how that goes... though I'd wait on a more stable firmware with better motherboard compatibility.

 

Some good reading material:

Here's the firmware:

I dont believe that I have done any thing other then regular use. I have already read that article and did the firmware up date the day I got the drive. Im running crystal disk mark. I will re-run and post results.

That's not good. I didn't update the firmware on any of mine. I won't until it's been properly tested and people stop complaining about the firmware update causing problems for them.

 

I'll run crystal disk mark on mine when I get home and we can compare. I've had mine for about 5 months, and use it slightly more than regular usage.

Here is what I got.

Your reads look good, but your writes look slow. I don't have crystal disk mark to test write speeds (not sure if I'd want to). You have to have the full license for cyrstal disk mark to test writes?

 

I could just do a sequential write test from my RAID 10 array, which has around 300 MB/s reads and see what the write speed gets to on my SSD.

I sure I got this as free ware as it is with read /write . I would be interested in seeing someone Else's to compare to.

Thanks.

Is TRIM enabled? You can check with the following at the command line:

 

fsutil behavior query disabledeletenotify

 

If it returns 0, it is enabled. If it returns 1, you'll want to hit up google and see how to enable it.

Ok so i dont have this problem(dont have a SSD) but i decided to run that cmd line test. It tells me i need adim privileges to run fsutil....... This is the only acc on the PC, it is the administrator. Whats with that?

Well, this sucks. My 5 month old Crucial RealSSD C300 128GB is this (no firmware update):

 

My 2 week old Crucial RealSSD C300 128GB is this (no firmware updat):

 

Trim is enabled on both.

 

Just as a reference, here's my scores with my Corsair P128:

 

And on my 8 disk Samsung Spinpoint F3 1TB RAID 10 on a SATA II controller with BBU during verification (may be skewed since array is in use):

 

And on my 8 disk Samsung Spinpoint F3 1TB RAID 10 on a SATA II controller with BBU after verification (may be skewed since array is in use):

 

And on my 4 disk Samsung Spinpoint F3 1TB RAID 10:

 

And on my 2 disk Samsung Spinpoint F3 1TB RAID 0:

 

There's definitely degradation going on, but yours seems to be holding up better than mine.

Start, type cmd, right click on app, run as administrator. Windows is picky.

I looked and got 0. Thanks, I did not know that I could even check for that. It seem to be going down fast. I may try to do a format

and re-clone back on to the drive this weekend to see if it helps. I am not willing to do a complete format and fresh install just to find out it did not help.
