Are SSDs Finally Worth the Money?

Lucas123 writes "The price of 2.5-in solid state drives have dropped by 3X in three years, making many of the most popular models less than $1 per gigabyte or about .74 cents per gig. Hybrid drives, which include a small amount of NAND flash cache alongside spinning disk, in contrast have reached near price parity with hard drives that hover around the .23 cents per gig. While HDDs cannot compare to SSDs in terms of IOPS generated when used in a storage array or server, it's debatable whether they offer performance increases in a laptop significant enough that justify paying three times as much compared with a high-end a hard drive or a hybrid drive. For example, an Intel 520 Series SSD has a max sequential read speed of 456MB/sec compared to a WD Black's 122MB/sec. The SSD boots up in 9 seconds compared to the HDD's 21 seconds and the hybrid drive's 12-second time. So the question becomes, should you pay three times as much for an SSD for twice the performance, or almost the same speeds when compared to a hybrid drive?"
