Seagate Momentus 5400.2 100GB Notebook Hard Drive Review
5 Star Review   By member praetorian - Jan 8, 2007   

Strengths: Very quiet, 8MB cache, long 5 year warranty, sweet spot for size and price (less than $1/GB)

Weakness: Ultra ATA/PATA is becoming outdated to Serial ATA/SATA, doesn’t use new perpendicular recording (so not the fastest or largest drive out there)

The Seagate Momentus 5400.2 is a 2.5 inch hard drive, a great upgrade for laptops. This 100GB drive uses two 50GB platters and has a good-sized 8MB cache (the standard on most laptop drives). The 5400 RPM spindle speed is a good balance between performance and power consumption, though power-hungry users may want to consider a 7200 RPM drive like the Momentus 7200.1. The 5400.2 is a very quiet drive (rated at 2.4/2.9 bels at idle/seek) which in reality was similar in noise-level to a 40GB Hitachi drive that came standard with a ThinkPad. Performance was good; however there are faster drives available like the Momentus 5400.3 since they use new perpendicular recording technology. Furthermore, this drive is Ultra ATA—good if your current laptop or enclosure uses this type of drive, but it will soon be obsolete (new laptops are already using the newer serial ATA drives). So while the Momentus 5400.2 is a very good drive on its own, unfortunately it will soon be eclipsed by models like the 5400.3 that use perpendicular recording. Drive manufacturers will be switching over to this new recording method, since it allows for faster drives with larger capacities (up to 160GB for now) and more shock resistance. Even further down the line, drives will be combined with flash memory for even better performance with lower power consumption. However for now, the 5400.2 remains the best value and is a very cost-effective upgrade for most laptop users. The 5-year warranty that Seagate includes is the industry’s best and no coincidence, Seagate drives are among the most reliable. Just be sure that your laptop uses the older Ultra ATA interface.

Momentus 5400.2 ST9100823A 100GB Hard Drive 5400RPM 8MB Cache
5 Star Review   By member Houston2007 - Dec 23, 2005   

Strengths: This hard drive is quiet, low power usage,faster access files because of 5400rpm with 8MB Cache vs my old Seagate 4200.2 that was 4200rpm with 2MB Cache.

Weakness: None I found

This hard drive is quiet, low power usage,faster access files because of 5400rpm with 8MB Cache vs my old Seagate 4200.2 that was 4200rpm with 2MB Cache. I accessed a lot of large files lot faster like Windows Media Video High Definition 1080p and 720p files. Installation was easy like plugging in a Nintendo cartridge into a Ninteno System. I looked into this drive because of it's specs 5,400 RPM and 8MB Cache and finally I chose this drive because of it's reliability anda Manufaturer. 5 year warranty. The original hard drive that came in the notebook was a Seagate 4200.2 that's a 40GB 4200RPM with 2MB Cache. It was fine but I wanted larger and more speed for large file handling. I brought a 2.5" USB External closure for the old hard drive. I have no problem out of it as a external. Seagate is trully reliable.

Review for Momentus 100GB 5400RPM
5 Star Review   By member sgitz - Sep 17, 2005   

Strengths: Fast (5400rpm), Quiet, Low Power Consumption, 5 year warranty, Fair price

Weakness: None found so far

When my old 80GB hard disk failed (in warranty), the manufacturer would take an indefinite time to replace (it actually did more than 3 weeks). Therefore, I had to get a new one, and I was definitely going to change manufacturer - 3 weeks without laptop? My first preference was Seagate, for the reputation of manufacturing the most silent drives. The second reason going with Seagate was the 5-year warranty (in contrast to the 3-year one of my failed drive, and 1-year of other manufacturers). After all, the price was competitive (for a 5400rpm drive), the numbers at the spec. sheets looked ok, so why not? After using the drive for two months, I can say that it is quiet (somewhat more quiet than my failed drive), and generates less heat than my previous drive (the fan of the laptop powers on less frequently). As a piece of advice to users that replace their internal laptop drives, I believe that the heat emission is important for system stability, something that most users probably ignore.

SEAGATE HARD DRIVE.
4 Star Review   By member marcin12 - Apr 17, 2005   

Strengths: 100gb of space, quiet, 5 year warranty,

Weakness: Kinda pricy, in my opinion doesn't appear much faster than 4200rpm hard drive

It's a big hard drive for a laptop, this hard drive is quiet, I tried hitachi 7k60 not sure about the model but it was the one with 7200 rpms and it was loud. The temperature for the hard is about 40c as i am typing this which isn't bad since hard drive doesn't come across air movement. Installation was easy, computer recognized hard drive right away no issues. In performance, I really can't tell if it's better than my old hitachi 40gb 4200rpm, I bought this hard drive purely for the space that it offers. I had 7200rpm(hitachi) 5400rpm(this drive) and 4200rpm (hitachi) all three drives performed about the same, accessing internet, typig, I couldn't tell diffence between them maybe because I am not playing any hardcore games or use hard drive intensive programs. Well there was one difference between hitachi 7200rpm and seagate 100gb 5400rmp, hitachi drive was louder and even louder when it was writing data into a hard drive. this hard drive is good, I give it 4 stars because of the price, good price for any hard drive is for $1 at least 1Gb UPDATE: WARNING POOR WARRANTY. MINE BROKE AFTER A YEAR. WELL, THIGS HAPPEN LIKE THIS SO THIS IS NOT A BAD THING. AFTER SEND THAT HARD DRIVE FOR RMA TO SEAGATE, WELL I HAD TO REPEAT THAT CYCLE THREE TIMES BEFORE I GOT A HARD DRIVE THAT WOULD WORK LONGER THAN A MONTH. SEAGATE SEND ME TWO HARD DRIVE THAT FAILED IN A PERIOD SHORTER THAN THREE WEEKS. THE THIRD ONE SO FAR IS WORKING.
