SSD recommendation for older computer?

[gryffinwings]

Need a recommendations for upgrading my current SSD to larger SSD, currently running a Sandisk SSD Plus 120GB, it's a little small for my needs. I already have a 1TB WD Caviar Black hard drive.

 

I feel that the 120 GB is a bit too small. I'm currently using around 75% of my SSDs space.

 

Computer:

Dell Precision T3500 - So it's running SATA II ports, no SATA III.

 

I don't feel like I would get any benefit from something like Samsung EVO SSDs.

You'll feel benefit because it's not only read/write speed of single big file but also all other parameters like access time, multiple small files read time etc.

But I agree that EVO for old computer may be too much. Try Goodram CX400 - cheap and good enough.

it's not just speed, but latency and durability.

I'm glad I asked, because I knew there was more to it, but I was not sure what else to be concerned about, one was durability, but wasn't aware of latency, how does latency affect SSD performance?

latency = time between system requesting a file and SSD starting file transfer. Proper SSDs have DRAM cache, used to store data on where each file is located in the NAND flash modules. Cheap SSDs lack this file though, instead saving this 'map' in the NAND flash itself. DRAM is faster than NAND, which creates a higher latency. Just like using a map in paper form versus a map in an app in a smartphone with good internet connection.

So this is basically how some NAS storage systems work using tons of RAM to map HDD arrays, makes since. So the Crucial MX500 has this feature? How can you tell what other SSDs have this?

PCPP shows SSD's cache capacity for those that has cache, though not all SSDs with DRAM cache has its capacity displayed.

Thank you for the assistance, I actually ended up buying the Crucial MX500 500GB version, the price difference wasn't that much to me and having more space makes more sense to me.
