Summary: I must admit for the longest time I was a holdout when it came to solid state drives. While all of my friends and even co-workers were building super PCs with SSD's, I was chugging along on my dual 7200.11 RAID 0 setup thinking those SSD's couldn't be that much faster. Now that I've converted all of my personal computers over to solid state, the one thing I really miss is the capacity I had previously.
Excerpt: The Seagate Laptop Thin SSHD is aimed at laptop owners who want the low cost and high capacity of a hard disk as well as the fast performance of a SSD. The SSHD is a 5,400rpm 2.5in hard disk that uses 8GB of NAND flash as a giant cache in order to increase performance. It’s the successor to the older Momentus XT range of flash-augmented laptop hard disks. We reviewed the 500GB version of the SSHD. It’s just 7.5mm thick, so it’ll fit within some ultra-portable laptops.
Conclusion: The idea of combining the best of the SSD and hard drive worlds into a single product is a novel one, but few products have truly taken advantage of the possibilities this approach offers. Seagate’s approach has thus far been the closest to absolute success and their SSHD Thin is unique in its direction but that doesn’t necessarily make it an outstanding storage solution for everyone.
