Dell COMPELLENT 600 GB SAS drive
This Dell COMPELLENT 7149N-CML drive provides 600 GB of storage on a 2.5 inch SAS 6Gb/s interface. It spins at 10000 RPM with a 64 MB cache and ships new with the COMPELLENT caddy included. It is suited for servers or storage arrays that require a 2.5 inch SAS hard drive.
SAS 6Gb/s interface limits
The SAS 6Gb/s link caps sustained throughput at the interface rate, so sequential performance cannot exceed that ceiling. Random I/O will also be bounded by the 10000 RPM rotational speed and 64 MB buffer. Systems limited to 3Gb/s SAS will operate at the lower speed.
600 GB capacity constraint
The single specification that decides fit is the 600 GB capacity; buyers who need more storage per drive must choose a higher-capacity model. This drive will not meet requirements for larger single-volume deployments.

คำถามเกี่ยวกับสินค้านี้
Should I pick the 600GB 10000RPM SAS drive or a larger capacity model?
This drive provides 600GB capacity at 10000RPM with a 64MB cache. If your workload needs more space than 600GB, choose a higher-capacity SAS drive; if speed matters more than space, the 10000RPM spindle keeps latency low.
What does the 10000RPM figure mean for real-world performance?
The 10000RPM spindle reduces rotational latency, so random read and write operations complete faster than on slower-spinning drives, improving transaction-heavy workloads.
How does the 6Gb/s SAS interface limit transfer speed in practice?
The SAS 6Gb/s link caps the maximum interface throughput at 6Gb/s, so sustained sequential transfers cannot exceed that bandwidth regardless of the drive's internal speed.
