I won't buy spinning disk for anything other than archival/backup storage now. SSD price/GB is relatively high compared to spinning disk, but for many use cases, you don't need multiple TBs of storage on a PC. On the server side, SSD makes a lot of sense today too. Although cost can be a larger concern because the scale is so much larger, I'm not sure that the cost is a huge concern compared to the other costs in a large enterprise environment. For performance-sensitive applications that are I/O-bound, it makes a lot of sense. As for completely replacing spinning disk, I suspect that transition will kind of be like the transition of disk replacing tape. Tape still has some characteristics that spinning disks can't quite match for particular use cases. It's just that the use cases are becoming more niche as disk storage prices continue to decline. Now if they can reduce flash price/GB 10x, then sure, *maybe* it will replace everything. I'm sure that sort of price decline will happen in time, just because flash is being used in so many more places than spinning disk. But that time frame is not going to be next year. Disk storage will undoubtedly get cheaper over that time frame as well. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
