Longevity of CF Cards, i.e., TRIM

[danbeaver]

Do any CF cards have TRIM capability? Is there some way to simulate this?  If not then how many R/W cycles before data is lost?  Most were designed for cameras and the like, which don't act like the hard drives in Amigas.

Thanks, glad to hear it!  I've been only using them for the past year and while I have found CF cards to be bus limited, SD cards are not; but then I've only used cheap ones. Due to the swap partition of OS 4.1, I've moved to an UW SCSI drive  for it. As SSD prices have fallen I've played with one on my PCI SATA card plus a modern DVD-RW.

Yeah but my A4000T is limited in OS 4.1 to 128MB of ram which, after loading workbench is then cut to half that. When it runs out of CSPPC memory it first hops to my 256MB ZorRam card, and when that is done to hard drive. While I can put a CF card on the IDE bus (damn slow compared to the CSPPC) to get a CF card on the SCSI bus (and only the CSPPC bus it really usable) takes 2 adapters (Acard to IDE then IDE to CF) which, when the speed is tested is much slower than CSPPC to SCSI UW hard drive.

Granted I use the CF cards for quick backups of boot partitions and such, I just wanted to know from this thread if over the next 27 years if I should archive my CF cards like I now do with my SCSI drives.

Geit:  I've checked speed between a X266 and an X600 CF card and they are bus limited on the Amiga (CSPPC Wide SCSI bus) as is a SATA III SSD drive; it just so happens at this point in time a 120GB SSD is cheaper by far than even a CF card; hence the origin of my question on longevity and TRIM technology. We can't all work with electronics and computers for a living so questions arise that can't just be Googled

I get 35 Mb/s with a 15k U320 Atlas but only 25 via ACard 7720UW (one of the 2 Mech sold me) with an IDE->CF adapter; the adapter is a generic off Amazon. Is there one that performs better? Oh same speed using an SSD via IDE->SATA. Slow as heck off the sii3114 SATA card.

[danbeaver]

Yes, that is what I thought.
