RE: OFF - Reconditioning SSD Drives
I can't speak to the reliability of TRIM on mac, but I know it works great on Windows (and automatically). It looks like you should be able to determine if the drive supports TRIM from the System Report (about my mac): https://www.cnet.com/how-to/installing-ssd-on-mac-trim-mistake/ -Tim -Original Message- From: 4D_Tech <4d_tech-boun...@lists.4d.com> On Behalf Of Dave Nasralla via 4D_Tech Sent: Thursday, August 09, 2018 5:59 AM To: 4D iNug Technical <4d_tech@lists.4d.com> Cc: Dave Nasralla Subject: Re: OFF - Reconditioning SSD Drives Thanks Tim, On the next system maintenance I'll look into the Samsung software.

Also, have you looked at the software provided by the manufacturer? https://www.samsung.com/semiconductor/minisite/ssd/download/tools/ The manufacturer software usually has some stuff to check if all the settings are correct and also benchmark the drive. -Tim ** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **
Re: OFF - Reconditioning SSD Drives
Is TRIM enabled? If not that would be my first step.

Recently I wiped the RAID and upgraded to the current OS from scratch doing a clean install of everything. Now I am seeing a fairly noticeable performance hit with write operations. I used to be able to duplicate a 400MB file in s few seconds, but not anymore. I am not running the new mac file system (APFS) on the RAID. I'm thinking the SSDs need to be reconditioned. Any one have any recommendations? (I can also connect them to a PC to do another wipe if necessary.) dave -- David Nasralla Clean Air Engineering ** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com ** ** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **
