Seagate Enterprise Performance 10K.7 Review Discussion

3 posts in this topic

The Seagate Enterprise Performance 10K HDD v7 is a 15mm 2.5" form factor drive that ships in a 1.2TB capacity, interfaces over 6Gb/s SAS, and, as the name implies, spins at 10K RPM. The 10K.7 succeeds the Enterprise Performance 10K HDD v6, aka the Savvio 10K.6 that we reviewed earlier this year, and with the new 10K.7, Seagate aims to match high performance with low overall power consumption to deliver a reduced TCO to organizations deploying drives for data centers and cloud environments. On that note, Seagate quotes sequential data transfers at up to 204MB/s, which is aimed at meeting the marks of some 15K RPM legacy HDDs, and the average operating power rating is 8.02W with typical idle operation at 4.65W.

What is the point of posting a ton of analysis & graphs about drive performance at latency values over 35-50msec? Many third-party applications will start barfing if drive latency goes over 15-20 msec (e.g. Oracle). Most of these graphs are describing drive performance with latency between 300-4000 msec. The area of greatest interest in drive performance is when latency is controlled for 5-15msec, and anything over 50msec is pretty much irrelevant in the context of practical usage.

Completely understand that, our synthetic benchmarks are just there for reference to compare the very fine amount of difference each drive has. The main focus in our recent reviews with sufficient quantities of drives from the manufacturer is moving to application testing so show that interaction under normal duties.
