I have an SSD, but many of my tasks are still significantly slowed by the storage read and write times? Is there any software that can somehow optimize it? I already switched to SSD so I can't improve hardware anymore.

I tried to search or ask around but couldn't find any good answer.

Please read this, then provide more information, such as the make/model of the machine, the distro/version you are using, and anything else that may seem relevant.

Oh, and welcome to LQ.

What data gives you the confidence to make this statement ?.

Load to ram, (if you can), will speed up your computing, but takes considerably longer to load.

yes, in general we can't suggest anything, there is no global solution. Would be nice to know more details, like:
how do you know it is slow (did you make any measurement or comparison)?
what is it all about (is it a database, a lot of small files or huge files or how is this storage used)?
what kind of OS and app is it?
what hardware do you have (storage, ram, cpu, swap, .... how is it configured)?

The very first step would be to find the real bottleneck, but without any usable information hard to tell anything.

I have seen several tools for speeding up storage access, the one I am most familiar with for linux systems is fstrim.

There is a tutorial for optimizing ssd access with fstrim, and a more general tutorial for optimizing ssd.

There are plenty of resources, but remember that none of them compare to the good old hardware upgrades.

You're barking up the wrong tree. Buy parts - that's how you do it. Spend money.

You get a go-faster stripe with fstrim. You get real speed with an NVME or two on a very decent motherboard. Watch your specs carefully, as my board has pcie-4.x on one nvme, but only pcie-3.x on the other. Anyhow, there's faster stuff about. Probably best to buy a server M/B.

Also an option is Raid 0, using 3 disks. Disks 1 & 2 stripe your data in turn, while disk #3 keeps track. Backups are essential.

Don't waste your time seeking some tweak that will magically multiply your access times or bandwidth.
