F.A.S.T. FACTOR TECHNOLOGY
The F.A.S.T. Factor Advantage Flash Assisted Storage Technology is what makes the melding of hybrid drive worthwhile. simply put, it is what makes the Momentus XT fast.
- FAST Boot Cold boot-ups within seconds of an SSD 24 seconds or faster on test systems, compared to 20 seconds for an SSD and 75% faster than a 7200RPM drive.
- FAST Flash Increases data integrity and reduces wear and tear on both the NAND flash and hard disk drive.
- FAST Read Produces high read speeds.
- Seagate Adaptive Memory Technology Self-learning algorithm gives users SSD-like response on their most frequently used applications and files.
What FAST is, is a term encompassing three firmware-level features: FAST Management, Adaptive Memory Technology, and FAST Boot.
- Flash Management – Momentus XT solid state hybrid drives also implement a management feature that provides seamless integration between hardware, firmware and high-speed NAND flash while maintaining data integrity under all conditions any system, any OS and with any driver.
- Adaptive Memory Technology – Adaptive Memory technology delivers SSD-like response from the applications and files you use the most. It lets the Momentus XT drive selectively tackle frequently used data, copy it to the flash, track its relevancy and keep the flash current. You get the instant response experience you need to perform at your best.
- FAST Boot -Momentus XT drives are known for incredibly fast boot-up times, and now they are even better with FAST Factor boot technology. This system boot-up technique can reduce your boot time to mere seconds for a fast cold-boot start. It can cut your system start-up time by up to 65% over a traditional HDD. FAST Factor boot technology will deliver the fastest boot possible, whether you boot your system once a day or once a week. Your OS boot-up files are always there, ready to work.
While it is unknown how exactly these features function, one thing that can be deduced is that FAST is meant to boost read performance, not write, a point clearly made using FAST Boot and Adaptive Memory Technology.
In that unlikely case, FAST management will convert the hybrid drive into a standard hard drive, keeping the data intact while only losing the SSD-like performance. The SSD bond really shows here, as traditional hard drives do not use firmware.
With all of these terms established, what about TRIM? As also mentioned previously, the Momentus XT is more of a hard drive than an SSD, with the SSD portion only making up 8Gb. Therefore, TRIM is not available, or even possible. This makes FAST Management even more valuable as it essentially acts as garbage collection for the Momentus XT, especially since files will not be copied to the SSD/NAND segment of the hybrid drive. Think of FAST Management as Seagate’s substitute for TRIM. It does not really matter how the garbage collection works, as long as it functions and prevents degradation.
Moving on, Adaptive Memory Technology deals with blocks that remain on both the hard drive and NAND. The technology monitors and adapts to how the user utilizes the Momentus XT in every-day computing. This is one of the major contributors to the overall speed of the Momentus XT drive, a fact witnessed during testing. There was a large performance gap between programs that were launched once to the same programs being executed, for say, the tenth time. Once the Adaptive Memory Technology figures out the user’s pattern of access, it stores that information on the NAND portion of the drive. Hence, for all benchmarks, the Momentus and Momentus XT’s results reflect at least ten access executions.
Those who reboot and shutdown frequently will obviously see a vast improvement in performance in a shorter period of time versus those who reboot infrequently. Theoretically however, after a broader time of usage, FAST Boot should perform equally for both crowds.
