RAID With Flash Hard Drives
SanDisk was kind enough to provide two SSDs for this review, because we wanted to see how they would perform when setup in a RAID 0 array. Flash SSDs are much more robust, don’t suffer from physical impact and endure higher operation temperatures (up to 70°C, depending on the model). Given its robustness, RAID 0 is more attractive for flash SSD compared to conventional hard drives, which can crash from one day to the next. Also, a potential sweet spot for future flash drives is RAID 0 with two flash SSDs.
