What SSD for DAWs?

Ok, few friendly people gave me very important advices about choosing a CPU. But as a newbie in a world of music producing, I don't know what SSD is better for DAWs. I don't know if is better to choose one with better sequential r/w, random 4k or what. My plan is to buy ADATA SU800 512 GB. Is there better in that price for music producing? Or would that be enough? Sorry for these basic questions, but as I said, I am newbie on music producing.

What are you going  to use the SSD for?  If its for the OS/DAW program, you probably only need 256Gb.  If it is for audio, you might want to reconsider as the performance impact of using an SSD for an audio is minimal.
 
I don't know a lot about the ADATA drives, but I have had good luck with the Samsung EVO series.

If you are adding additional software that can utilize the benefits of an SSD, bigger probably is better.  For my laptop, which is not my main Sonar workstation, I have an SSD and a 1TB drive.  The 1TB drive keeps most other programs and data.  The SSD has the OS and Sonar (mainly because I want Sonar and projects on two separate drives.)

I think any reliable brand of SSD should be fine.  I have had a good experience with the Samsung EVO 850 250GB.
 
This drive is SATA 6Gb/s compatible, but is currently used on a SATA 3Gb/s port.  Windows boot in a few seconds, and Sonar opens in a snap as well.
 

 
At this speed, a few percentage points are hardly noticeable. 
 
But from the numbers I have looked at, a modern spinning HDD at 7200RPM can handle audio tracking just fine.

Thank you, now I see, that the Kingston UV400 (I have it right now) with 560/495 is usable too.

With those numbers, you must be running on a 6Gb/s SATA III port!  You should be fine with that Kingston.
 
I may have to look into that brand, as the Samsung have gone up in price, and I need to move my samples off a 7200RPM drive soon.
 
I have been running my SSD daily since Dec 2015, and it still shows a status of 100% life remaining, so the longevity of these modern SSD's also looks pretty good!  I do make monthly image backups to an external drive, just in case of a controller failure or something else eating my data.

If sequential read is very important part of SSD for Sonar, you could look into that ADATA SU800. 

This is stability of it in AS SSD compression-benchmark. SU800 is cheap and have right quality. My UV400 definitely does not achieve this result as SU800 in picture.

check out the new crucials 1tb for secondary drives for your files and data?... costing what the others cost at half the size....but read reviews...cheap for more space less performance speed, might not be the way to go ?...depends on stability and life of without issues or lost data...as it is new...beware?.
 
One for the os?....well check it out.
 
.
ADATA are just fine here.
Crucial also work fine here.
Samsung evo also working fine.
 
 
 
 I have read in past, from dependable friends, Kingston ssds were not always dependable....So I did not try them out, yet since reading into that years ago...if they had a issue back then, they surely solved it by now?...i think it was a controller issue with the firmware that I read into .
 
Intel's ssds are more expensive but, it is supposedly more solid performance,and so built with a higher level of X is said to allow the price point of higher sales pricing, for that stability in the firmware or chips or the way it divides the digits into the memory chips....some say is worth it, if you value your data being never to be corrupted under it's terms of warranty...But then again..did not try....you can read into it if you google some.
 
 
So Price per performance these days is up to you.
And manufacturing and testing or burn in, is usually done before they ship the distribution to market these days.
You may find the odd bad apple in all of all if so one gets out....and if cutting prices, they cut somewhere in that development...it could be the burn in where they cheap out some, to lower the cost....if not the cut other higher price parts, for lessor price parts....ect.
 
But again, not all things work with other things....check the MB chipset is able , and no hick ups with MB drivers and onboard devices, Bios levels, and which sata ports do what, and in what order they implement as Drive 0 and drive 1, and express ports... etc .
 
As boot device order may only be the concerns these days, and proper bios support for this type now standardized into detecting properly...and it may not matter much with a good stable MB chipset, and parts put, and the drivers and firmware established proper on the MB.
 
Do the home work, and read the reviews of the new stuff...if so interested.
 
Hope it all helps build a nice system.
 
cheers.
