Romex Software Forum

You are welcome. I am glad you see merit in the idea.

I have idea for Romex to research and to possibly incorporate into PrimoCache. It might break some kind of new ground in caching. I do some independent scientific research and one of the areas that fascinates me is conservation of symmetry. This could be implemented in a way into PrimoCache. Assumin...

If I have L1 100% Read only but L2 R/W I notice that it will write to L1 if the data modified is in L1 cache and that is fine and great. My question is that if that data is also In L2, does it update L2 also or does that get evicted from L2 and only returns to L2 if that data is read again?

You are correct. I even took a drive from another system and replaced one of the drives and still have the problem. It works fine if the striped drive is a regular volume and survives the reboot but when a striped drive becomes formatted with PrimoCache it is not recognized by Windows after reboot. ...

I've disabled "Turn off Windows Write Cache buffer-flush" option.  It was creating a cache over a cache and PrimoCache is better in caching content and skipping direct writes. Let me make a quick point on this. As I understand it, you still want the Windows Write Cache Buffer turned on be...

I am not sure if this is a PrimoCache problem or a Windows problem. I had an L2 200 Mb striped drive from two SanDisk SSDs. After a power outage something was affected because now if I setup a striped L2, after a reboot it becomes disabled and disappears from the L2 Storage List. I then have to go i...

are the read times for Windows cache uncompressed not shown in the image? Or am I misunderstanding something here? There is this column for "Windows Cache Read" with values around 1,1xx - that is not what you meant? I don't realize where you read the 23% faster reads than from uncompresse...

Thx for the tests RobF99. As: Xpress4K compresses data in 4KB chunks. Xpress8K compresses data in 8KB chunks. Xpress16K compresses data in 16KB chunk https://docs.microsoft.com/en-us/windows/win32/api/wofapi/ns-wofapi-wof_file_compression_info_v1 Some questions: Did you use the std 4K cluster size ...

Yes these methods - XPRESS4K, XPRESS8K, XPRESS16K, LZX compress on the fly. Much different from the way NTFS compression compresses, which is as you described. The NTFS compression in Windows 10 still works the same classic way, but those methods are far more different and much faster too. They also...

I noticed a few users asking for a compression feature within PrimoCache. I am sure it is a difficult feature to implement and potentially introduce issues with data integrity and unnecessary overhead. Instead, just compress your data on your drive using the excellent new compression options in Wind...
