That's what I would expect ... I don't have one, so I can't say much about them. Is it a good choice for your application? Considering their cost, SSDs don't seem worthwhile to me unless you have an application that does make use of them. They probably make quite some sense in laptops unless you need storage capacity because their power consumption is low and because they aren't affected by vibrations. A hybrid doesn't (fully) have these advantages. With a hybrid, you get two different devices combined into a single device, each of them having their own weaknesses. That probably doubles the overall chance of failure of the device like the chance of failure of one disk doubles when you use two disks instead of one. Considering cost, you can get like a 32GB SSD plus a 500GB disk for about the same money as you'd pay for the hybrid. That still doubles the chance of failure (assuming SSDs have about the same failure rate spinning disks have, which they probably don't). You could get two 500 or 750GB or 1TB disks instead and use RAID-1: still double chance of disk failure, much less chance of overall failure, easy to fix. If you don't need much disk space and think you can get away without redundancy, you could get a single 32, 64 or 128GB SSD and, if needed, an external USB disk. Or you can have redundancy with two 32GB SSDs and the USB disk carefully backed up to your desktop, though backups aren't a replacement for RAID > 0 ... You have many choices :) Having that said, the only case that comes to mind in which a hybrid currently could make sense is when you don't have a choice. In practise, they might work fine. The product must be as cheap to manufacture as possible, and the majority of them needs to survive the warranty period.
