stepmback Posted August 15 Share Posted August 15 I recently upgraded my nic to a 10gb card. My server is pretty old but runs like a top. I have a 512 GB samsung SSD setup as cache. I have my workstation and server connected to 10GB switch via a DAC cable and everything seems to be working fine. However, when I try and transfer a large file, like a 60GB file, it hums along at 500 MB/s for about 40 seconds then drops to 80 MB/s. I am wondering if it is my SSD, CPU (old) or some setting I should change. Any help is appreciated.auburn-diagnostics-20240815-1115.zip Quote Link to comment
JonathanM Posted August 15 Share Posted August 15 Look up the specs on your SSD, it's probably got a "fast" section that is filling up on large transfers. Quote Link to comment
stepmback Posted August 15 Author Share Posted August 15 That may be it. It has 42GB of turbo write. I had no idea. That info is buried and not in their standard specs. Quote Link to comment
JorgeB Posted August 15 Share Posted August 15 That's fairly typical unfortunately for most SSDs today, and you have a QLC model, so it's more affected than TLC models, like the 870 EVO, which is one of the few that can still sustain a high write speed. Quote Link to comment
stepmback Posted August 15 Author Share Posted August 15 I really don't need 1TB (which is what I have now). Also there are some errors on my current cache drive. For $55 I could by the 500GB version of the EVO. Would this solve my problem of limited turbo speeds for 100GB files? https://www.amazon.com/SAMSUNG-500GB-Internal-MZ-77E500B-AM/dp/B08QBMD6P4/ref=asc_df_B08QBMD6P4/?tag=hyprod-20&linkCode=df0&hvadid=692875362841&hvpos=&hvnetw=g&hvrand=5722533018106623447&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9008123&hvtargid=pla-2281435180938&mcid=789e57033e423e47ba624b30a23301bf&hvocijid=5722533018106623447-B08QBMD6P4-&hvexpln=73&gad_source=1&th=1 Quote Link to comment
JorgeB Posted August 15 Share Posted August 15 The 500GB EVO can sustain 300MB/s after the pseudo SLC cache is exhausted, which is much better than the QVO, but you would need the 1TB model for constant 500MB/s: Quote Link to comment
stepmback Posted August 15 Author Share Posted August 15 Hmmm... do they make faster versions or is this a SATA limiation? My server is old so no NVME. Quote Link to comment
JorgeB Posted August 15 Share Posted August 15 It's not easy currently, older 500GB (and even some 250GB) MLC models could easily keep up with 500MB/s for the whole device, but those are only found used nowadays. I have some older 128GB MLC Samsung drives that I use on my test server, that can sustain 400MB/s. Quote Link to comment
stepmback Posted August 15 Author Share Posted August 15 I might just live with it for now. I have been thinking about upgrading my server for 4K transcoding. Just another advantage to upgrading. Quote Link to comment
