Hello,
I've just received for my birthday a nice SER 5 with Ryzen 5 5560U ![](static/image/smiley/Skype/1 (55).gif) .
But I've noticed some big latency (database and other) with the intregrated nvme ssd. I've installed an other 1to SSD SATA in the PC (on mounting point /ssd) for the comparaison.
I've started several bench, on big file it's ok : Integrated SSD : dd if=/dev/zero of=/root/testfile bs=1G count=1 oflag=direct 1+0 enregistrements lus 1+0 enregistrements écrits 1073741824 octets (1,1 GB, 1,0 GiB) copiés, 1,09347 s, 982 MB/s
The other 1to SATA SSD : dd if=/dev/zero of=/ssd/testfile bs=1G count=1 oflag=direct 1+0 enregistrements lus 1+0 enregistrements écrits 1073741824 octets (1,1 GB, 1,0 GiB) copiés, 2,36882 s, 453 MB/s BUT, on small file...
Integrated SSD : time dd if=/dev/zero of=/root/datei bs=1M count=10240 oflag=direct 10240+0 enregistrements lus 10240+0 enregistrements écrits 10737418240 octets (11 GB, 10 GiB) copiés, 390,223 s, 27,5 MB/s
real 6m30,226s user 0m0,049s sys 0m3,492s
The other 1to SSD SATA installed in the PC :
time dd if=/dev/zero of=/ssd/datei bs=1M count=10240 oflag=direct 10240+0 enregistrements lus 10240+0 enregistrements écrits 10737418240 octets (11 GB, 10 GiB) copiés, 25,413 s, 423 MB/s
real 0m25,416s user 0m0,044s sys 0m2,339s
--> So more than 6 min vs 25 sec to write 1M file !
Could you help me ? Is there an issue with my integrated ssd ?
(The SMART is OK)
Thanks
