Do it! Post benchmark numbers pls.

sorry just to check samsung 850 msata still no news when will come in malaysia?

Major issue!
I've encountered some problem with my 2 year old Plextor M5S SSD.
The Sequential Read/Write speed I used to have a few weeks ago was 512/268MB/s

And these few days I've realized that my PC was a little lagging and I couldn't found the source.. So I just whip out the trusty Samsung Magician to check the performance, and to my surprise.. THE SEQUENTIAL READ SPEED DROPPED BY 50%!! THE HORROR!! even the official Plextools was showing me the same result.

Are my ol'SSD dying?! Can it be fix? or I have to RMA it? :'(
Any help is pretty much appreciated.

Oh btw, what do you guys recommend for a 120/128GB SSD? Hope it's not a Plextor, because I can't take another jump scare.

I think if formatted it performance will be back as usual

or sell it and get lite on 256gb instead

Using Samsung test on competition drive can be biased. Use Crystaldiskmark or AS SSD.

Of course I dint test it with just one benchmark tools, I did also tested it using Plextool as well, same results. :\

Update:
Just look at it man.. I can't bear to watch :'(

That is definitely low. Try looking for updated firmware or reformat or RMA it.

what kind of issue with SSD that we can RMA it?
speed degradation also include?

Did you ever enable TRIM command after you install Windows?

*By default it should be enabled, but there are times it can be disabled due to other components.

Plextool shows that the TRIM is enabled.
I've even check it using cmd using command:


By the way, I've updated the firmware to 1.05 (previously 1.03) and the results are still the same.

Now im just wondering that will speed degradation issue can be accept for RMA.

Ssd performance will degrade over time, especially the used capacity is over 50%. Over provisioning and sufficient time for garbage collection can help but eventually you will need to do a secure erase once in a while to get back the speed.

this is mine..im using plextor m5p 128gb..
just updated my firmware from ver 1.05 to 1.08..

my transcend SSD340 256GB (left) and SSD370 512GB (right)

not bad for a budget ssd.. hand so itchy to try raid0

I thought those issues only affect SandForce Controller..

no. all ssds have this because this is about how nand flash works.

when a file is deleted, the process doesn't delete all the file data. there will be partially filled blocks that are not cleaned. note that the trim command only ask ssd to remove file data when it's deleted, but it doesn't force the cleanup operation to these partially filled blocks. to mitigate the issue, garbage collection is used to do this, by looking for partially filled blocks in the ssd, and clearing them to make free space. over provisioning is also important i this case to prevent performance degradation, by giving free space to the controller to do gc.

usually secure erase will reset everything to the factory state. (well, close to i should say)

I hope you're right, I wish you're right. I've just erase everything and did a fresh install, and the results is the same.

all hope is lost, in the hospital you go~

Now then, could you guys recommend me a good price/performance SSD please?

can anyone tell me how to do over provisioning on plextor SSD..
i owned samsung and its easy to do that..using samsung magician..
how about plextor?

Hey guys, I've made some research on my own and I made a list.
1. Samsung 840 EVO 120GB
2. Crucial M550 128GB
3. Intel 530 Series 120GB

For these three items above, which are the best? Or you guys have any other better options please let me know.

If I were to buy it would be 1, 3, 2.

If i have money then samsung 850 evo the reviews online are fantastic. Some new tech, 3d chip or something like that.

Intel is well establish company and offer good warranty.
