brentpresley Posted August 14, 2013 Author Share Posted August 14, 2013 Samsung 840 Pro 256GB. In a desktop system with SATA 3.0 I can get about a 550MB/s peak off the drive. Link to comment Share on other sites More sharing options...

Yes, the Samsung 840 Pro is a very good drive. This is what I get with a single one on a SATA III port And two Striped together in a SW RAID 0 gave me: Link to comment Share on other sites More sharing options...
cskenney Posted August 14, 2013 Share Posted August 14, 2013 Only the first 2 slots in the drive cage are SATAIII (I believe) so it's no surprise the ODD slot connection would test out as SATAII. Link to comment Share on other sites More sharing options...

Excellent point! My concern (that I should have explained earlier) had been the possibility that the ODD SATA II port in the Gen8 was "down graded" like what we had seen with the ODD SATA II port in the previous generations of MicroServer's that required a change in the BIOS in order to get the full SATA II Speeds -- as proved necessary in Performance Improvement on ODD SATA Port Contributed by BIOS-MOD -- 300MB thru-put for an OS drive on the SATA II up in the ODD space is fantastic in my book -- life is good!

ikon Posted August 14, 2013 Share Posted August 14, 2013 If I understand it correctly, the limit of 2 SATA III ports is a result of the chipset used on the B120i controller only supporting two 6Gbps ports. Link to comment Share on other sites More sharing options...
Joe_Miner Posted August 14, 2013 Share Posted August 14, 2013 If I understand it correctly, the limit of 2 SATA III ports is a result of the chipset used on the B120i controller only supporting two 6Gbps ports. Check the Quick Specs and you'll see that the Gen8 MicroServer uses the Intel ChipSet C204. The C204 supports 6 SATA ports but only a Max of two of those ports can be SATA III's (the rest are SATA II's). It is the C204 that is the driving factor.
