Poor write speed of Kingston DC400 SSD on G7 Server
Hello,
I am using Kingston SEDC400S37/960G Enterprise SATA SSD on HP DL 380 G7 server.
Its giving me gud read performance but the write performance is very poor.
SEQ Read - 247.96 MB/s Write - 82.21 MB/s
4K Read- 15.40 MB/s Write - 1.63 MB/s
Acc.Time Read - 0.302 ms Write - 2.431 ms
I have P410i Raid controller and firmware/drivers are updated.
SSD Firmaware is also updated.

Re: Poor write speed of Kingston DC400 SSD on G7 Server
Have you solved this issue ? Because I have DL380e Gen8 with P420/1GB FBWC, 2x Xeon E5-2450L, 128GB of RAM, DC400 960 GB in RAID-1 and my server is also horribly slow ! :o

Re: Poor write speed of Kingston DC400 SSD on G7 Server
Hello,
I think is the same problem i get with samsung 840 pro.
You need to enable the disk cache write. The DC400 have a lot of features is made by the firmware (like dataprotection is soft and not by capacitor).
did you try to send a support request to Kingston too ?
Did you try to configure the controller cache to 100% read or 100% write ? Or simply Disabled ?
Best Regards
Vincent
