I contacted Crucial's Customer support.

Here is what a level 2 guy said to do:

The behavior you are describing is consistent with deleted cells not being cleaned from your drive. This can result in reduced performance or even complete lack of response from the SSD.

There is a feature built into our SSD's called Active Garbage Collection. Letting Active Garbage Collection run on the drive for an extended period will clean these cells and restore the SSD to a healthy state.

To manually force this command in a PC, simply disconnect the SATA cable from your SSD and only leave the power cable connected. After switching your PC on, the SSD will be in an idle state but still have power so Garbage Collection can function. Leave the PC powered for the 6-8 hours.

In a laptop, power on with the SSD installed and enter your system BIOS (please refer to your system manufacturer’s documentation on how to access the BIOS.) Leave the laptop in the BIOS menu for the 6-8 hours.

Following this process, your drives functionality and performance should be restored.

To prevent the SSD performance degrading again, you can make adjustments to your power settings:

- Go to Control Panel
- Go to Hardware and Sound
- Go to Power Options
- Select Change Plan Settings
- Select Change Advanced Settings
- Make sure the 'hard disk' field is set to ‘never’ (Laptop users select 'battery and power adapter').



I was told if that did not rectify the issue they would replace it.

I am sceptical about just leaving the SSD powered on for a few hours but i will try it

I spoke to a gentleman called mark told me to run hd tune and see what the drive health was like mine had a warning on it something to do with the DMA he sent me an RMA number straight away plus I kept losing drive and getting stuttering in games windows running sluggish as well from time to time
 
This is my samsung 840 500GB (none pro)

Azza's drive is 64GB capacity so is likely to have fewer dies and/or controller channels in use meaning fewer simultaneous writes can be sustained. Being a smaller drive he might also have fewer free pages to dump data too and the drive has to start clearing and re-writing partially full blocks on the fly.
 
I used ~115gb at one point on my M4 128GB. Testing gave about the same results

Is it best to test a drive when its empty / just windows installed? I have used about half of mine at the moment
 
I dont know how big the test file is in AS SSD but I imagine you'd have to be pretty close to full for on the fly data shuffling to cause a noticable impact. I think the fewer channels/die packages are probably the main reason for the lower writes in Azza's.

If TRIM and GC (for the writes) are working it shouldn't make much of a difference, but the fewer concurrent I/O's by a fresh OS install/empty drive will boost overall bench results a little.
 
Isn't this thread due a complete overhaul? A lot of new drives since the thread was launched, it would be great to see some multi-raid 0 on say 3 or 4 new drives with the different onboard controllers :)
