P256 SSD “Performance Recovery” feature minimum firmware?


Recommended Posts



Quick question. I have a P256 SSD that has hit the wall. Write speeds are SLOOOOW. I tried following the instructions for the “Performance Recovery” feature (idle garbage collection), but it did not help.


What firmware was this feature added on? Is it only the latest firmware? I have VBM1801Q.


I guess I am going to have to wipe, upgrade the firmware and reload my backup to get my write speeds back? I am running Windows XP.

Copied from the P Series sticky post, just above this one in the sticky section:


Q: Will the performance of my P-Series SSD reduce over time?


A: P-Series SSDs with firmware VBM18C1Q offers a “Performance Recovery” feature, which allows the controller to maintain optimal performance over time. For this feature to function the SSD must have at least 15% free space available and be formatted using the NTFS file system. The PC or laptop must then be cold-booted (i.e. turned on from a full power-off state, not a ‘reset’) and left in an idle state for one hour, after which time full performance will be restored.

Yup. Saw that. I was just wondering if that feature appeared earlier. The language doesn't say that that feature was NEW in VBM18C1Q, just that it exists in VBM18C1Q.


Anyway, I guess I'll flash the device and find out.


Just to confirm, the “Performance Recovery” feature will allow my drive to continue to perform well over time while I am running Windows XP. I don't have to upgrade to Win7 to make use of it. Right?

Results... I ended up not being able to re-image my XP drive back after the firmware upgrade, so I gave up and installed Win7.




Good stuff!
