Will performing a secure wipe (zeros) on my entire SSD increase its performance?

I have had this SSD (in sig) for 1 and a half years now... I didn't benchmark it when I first got it but now Im thinking, will a secure erase (as in, writing 0s to all clusters of the SSD) improve its performance?

Shall I do it or no need to waste my time?

AS SSD Benchmark with IRST 11.7.0.1013:

Probably not much improvement at all. TRIM/garbage collection takes care of that issue (having to secure erase to get performance back up).

No, and no.

A secure erase erases, on SSDs. The only writing that is done is is the firmware updating its tables to reflect unprogrammed flash. Writing zeroes is not the same thing.

Technically, it would improve performance, until you wrote another 240GB to the drive. But, that's what TRIM and idle time are for. With a SF controller (the Kingston), TRIM is necessary, and idle time helps. With most others (like this Plextor), TRIM and idle time both help, but idle time tends to be more important (just set your PC to not go to sleep until after at least 20 minutes, and you should be set).

All in all, (a) don't buy a SF-based drive with a controller older than the SF2281, (b) make sure TRIM is passed (Win7, with a +AHCI, or iastor in general, and you're fine), and (c) don't beat it to death with torrents or stuff like that.

thanks a lot for this informed post man!

PS: my SSD is not sand force based ()🙂
