Dell 745GC 300GB SAS Drive

The Dell 745GC is a 300GB enterprise hard drive with a 10,000 RPM spindle speed and a 2.5-inch small form factor. It connects via a Serial Attached SCSI interface rated at 600 MB/s data transfer rate. This new drive is built for server environments requiring hot-swap capability. It suits administrators needing reliable storage for non-mission-critical workloads.

600 MB/s SAS Interface Limit

The SAS interface on this drive delivers a maximum data transfer rate of 600 MB/s. This bandwidth ceiling is set by the 6G SAS standard the drive uses. Workloads demanding sustained throughput beyond this limit will saturate the connection. Buyers who need higher interface bandwidth must select a drive supporting a faster SAS generation.

300GB Capacity Decides Fit

The 300GB capacity is the primary specification determining whether this drive fits the storage requirement. Arrays needing larger individual drive sizes cannot use this model. Buyers who want more storage per drive bay must choose a higher-capacity unit. The 10,000 RPM speed and 4.5ms average seek time support performance within this fixed capacity.

Perguntas sobre este artigo

Should I pick the 300GB or the 146GB capacity?

The 300GB model stores twice as much data as the 146GB version while keeping the same 10000 RPM spindle speed and 600 MB/s transfer rate, so choose it when you need more space per drive bay.

What does the 600 MB/s transfer rate mean once the drive is installed?

It is the peak SAS interface throughput; real-world sustained reads and writes will be lower and depend on the RAID controller, queue depth and workload mix.

The drive uses a 6 Gb/s SAS link — what does that cap in practice?

The 6 Gb/s SAS connection limits maximum burst speed to 600 MB/s; actual I/O performance is governed by the 10000 RPM mechanics and 4.5 ms average seek time.
