We have 3 disk options that conform with the low power requirement (< 2-3 Watts?):
To compare options amongst these drives, we need common parameters that give us a decent and standard metric. Some parameters are:
- Power Consumption (Idle and Peak)
- Read/Write Speed (Data Transfer Rate)
- Sequential Data
- Random Data
- Cost per Gigabyte
- I/O Interface Support and Bottlenecks
- PCIe
- USB 2.0/3.0
- SD/MMC
RAID
RAID gives the option to provide better read/write performance.
OCZ Vertex2 120GB SSD (Measured 230 MB/s write throughput)
RAID0 was installed on 2 disks and achieved measured 469 MB/s write throughput.
