Hi, has anyone experiences with hp-branded ssds for journaling? Given that everything else is fixed (raid controller, cpu, etc...) and a fixed budget, would it be better to go with more of the cheaper 6G SATA Write intensive drives or should I aim for (then fewer) 12G SAS models? Here are the specs:
HP 6G SATA Write Intensive 200 GB (804639-B21): - Sequential reads / writes (MB/s): 540 / 300 - Random reads /writes (IOPS): 64,500 / 42,000 - DWPD: 10 HP 12G SAS Mainstream Endurance 200 GB (779164-B21): - Sequential reads / writes (MB/s): 1,000 / 510 - Random reads /writes (IOPS): 70,000 / 51,000 - DWPD: 10 HP 12G SAS Write Intensive 200 GB (802578-B21): - Sequential reads / writes (MB/s): 1,000 / 660 - Random reads /writes (IOPS): 106,000 / 83,000 - DWPD: 25 (Source: http://www8.hp.com/h20195/v2/GetPDF.aspx%2F4AA4-7186ENW.pdf) I know that asking does not free me from benchmarking, but maybe someone has a rough estimate? Best regards Karsten
