Its read speed was better, at around 90MBps. When used as a secondary drive in the system, it offered just about 39MBps for write speed. On the other hand, the Laptop Thin SSHD was terrible at data transferral. Compared with SSDs, however, it was still appreciably slower. The new drive also showed improvement in overall performance and helped applications launch noticeably quicker, compared with a regular hard drive.
Right after the system was moved to the SSHD, the first boot took about 45 seconds. Note that the boot time improvement only shows starting at the second boot. The same machine generally takes about 50 seconds to boot when it runs on a very fast regular hard drive. On one hand, it did well in boot time, taking just 15 seconds for the test machine to boot up, compared with 10 seconds for most SSDs and 20 seconds for the second-generation Momentus XT. PerformanceI tested the Laptop Thin SSHD against both SSDs and the Momentus XT 750GB hard drive, and it offered mixed results. In the future, there will be SSHDs with up to 32GB of flash memory. This helps lower the drive's cost but potentially means the flash memory part might become unreliable faster due to the lower write endurance ( read more about that here), especially since the SSHD has only 8GB. The second difference is that the NAND Flash memory part of the SSHD is now made of multilevel cell (MLC) NAND - similar to the type used in most consumer-grade SSDs - as opposed to the single-level cell (SLC) NAND, used in enterprise-grade SSDs. In fact, in my trial, it was about as slow as a regular 5,400rpm drive. This means that the new drive is slower at data transferring, such as when copying a large amount of data from one drive to another, or from one place to another within itself. The first difference is the drive's spinning speed, which is now only 5,400rpm, as opposed to the Momentus drives' 7,200rpm. On the other hand, the Laptop Thin SSHD is also quite different from the previous generation of Seagate hybrid drives. This proved to be trued in my testing, the test machine's boot time only improved (taking much shorter time) starting with the second boot. For example, once you have replaced a computer's hard drive with a Seagate SSHD, the first boot time might not show any difference at all. By design, AMT has to "learn" the patterns in which someone uses a computer and improvement is only observable in the subsequent times the same task is being executed.
