TL; DR: Does Primocache application really work?
Yes it does.
Disclaimer: I'm a happy registered user of PrimoCache. 45 years old, I've had my share of both smartdrv and Host Memory Buffer NVMe SSDs.
I have a HDD which has read/write speeds around 100MB/S
I'm expecting a peak speed here, ie sequential, no multi-threaded.
But in actual test of copy a file from windows explorer (from internal SDD) to this HDD read/write values remained same as around 100MB/s.
Let me sum it up, to be sure not to miss the point. You did not set up a cache on your SSD, you set up a cache on your HDD, and you copied a file from your SSD to your cached HDD.
Two things to consider here:
- what is the speed of your SSD? Have you tested copying a file from SSD to a RAM Disk?
- when you're writing the file, as long as the cache is not full, the data is copied to the cache. Once the cache is full, the file will be copied to the physical disk, getting you back to slow speeds.
I want to see if anyone have tested this software successfully or this software somehow fools the disk benchmarking tools to show huge numbers.
I have tested this software extensively before buying it. I quickly gave up on CrytalMark that only shows irrelevant values. What matters to me is actual file operations. And I can testify that, as long as you keep in the limits of your cache, this software does what it tells it does.
But to answer completely to your questions, let me write a bit more about how I use this software.
I have a SATA cacheless SSD, 16GB of RAM. Software engineering has been my main job for 20+ years.
I have set up a 1.25GB of L1 Write Cache, with defer mode, buffer strategy, flush on sleep.
I don't care that much on prefetching data. My main reads are loading the OS (un-cached), loading Eclipse (once a day, always-on then), launching and closing several Firefox/Chrome windows and tabs (could be cached, but Windows keeps the programs in memory, so irrelevant).
I care a LOT about writing data.
- you mentionned speed, and speed IS relevant. Gone are the days where I could stand the hourglass.
- looking at the PrimoCache stats, it becomes astounding how much your system writes to your disk, without needing it. It writes data, that wouldn't need to be written, or that would be rewritten later.
- by writing less, I make my SSD last longer. I'm not sure the PrimoCache fee is cheaper than a new SSD, but I'll be the one wearing it off. Not an other process.
- I've also setup a 512MB RAM disk, for %TEMP% folder, for good measure.
Does Primocache application really work?
Yes Sir, yes it does.
I'm not the only one to say it. See Dave's video, retired Microsoft engineer, and author of an Amiga cache software Supercharging Windows Disk Speeds
Is it the product for you? Well, try the demo. 30 days is a good amount of time to make up your mind. Run your computer as usual (ie, no CrystalMark), and see.
Then you could add your answer here ^^
