Solid State Hard Drives (SSD) in the 722 and 744T
Solid state hard drives, or SSD drives, are becoming a feasible storage medium for portable recorders and computers. Like CompactFlash cards, SSD drives have no moving parts and greatly extend the environmental operating conditions of the recorders. SSDs can operate in more severe temperature and vibration environments compared to traditional, spinning-disk hard drives. Additionally, they draw much less power than a traditional hard disk.
Compared to other solid state storage mediums such as CompactFlash, SD cards, P2 cards, and Express Card storage, SSDs have much higher storage capacities. Their larger physical size can accommodate more memory chips.
Sound Devices tested the Transcend SSD drive model TS32GSSD25-M. This drive performed properly, as expected, and can support up to four tracks of WAV audio recorded at 24 bit/96 kHz. We anticipate that other PATA (parallel ATA drives) SSDs to perform similarly.
