FAQs
Is 146GB enough capacity for modern enterprise workloads?
For performance-tier hot storage, 146GB drives are used in RAID arrays where IOPS, not capacity, is the priority metric.
What is the seek time of the ST9146853SS?
It has an average seek time of approximately 2.9ms, enabling very fast data access for random I/O server workloads.
Can this drive be used in IBM System x blade servers?
Yes, with an appropriate OEM carrier tray, this SFF SAS drive is compatible with IBM System x and Lenovo ThinkSystem blades.
How does 15K SFF compare to SSD for performance?
SSDs significantly outperform 15K HDDs in IOPS and latency; however, 15K HDDs offer larger capacities at lower cost.
What RAID type maximizes IOPS for 15K drive arrays?
RAID 10 maximizes random IOPS for 15K arrays, trading 50% capacity overhead for the best read and write IOPS.
