Closer Look

Samsung SpinPoint M60 120GB and 100GB (HM120JC and HM100JC)

Our major heroes today are the two new 2.5” hard disk drives from Samsung’s second generation of products. Their major distinguishing feature is the use of larger 60GB platters, as you may have guessed from their family name. These platters are designed with the TMR effect (tunnel magneto resistance). The HDDs are 120GB and 100GB respectively (however there are also 60GB and 80GB models in this product family) and feature an 8MB buffer. The spindle rotation speed is 5,400rpm.

The drives provide average seek time of 12ms, and track-to-track of 2ms. The average latency is 5.6ms. UltraATA interface ensures maximum theoretical data transfer rate of 100MB/s. the hard drives are highly shock resistant. They can withstand up to 300G of operational shock and up to 1000G of non-operational shock. The HDDs are 9.5 x 100 x 70mm big and weigh about 100g.

These hard disk drive family uses hydro-dynamic bearing motors. They are also built with Wireless Suspension heads. Among other supported technologies we can certainly name such things as SilentSeek, Silentec Hybrid latch and Load/Unload.

The HM120JC HDD sells at about $145, while the smaller mode, the HM100JC – for $125.

Western Digital Scorpio 120GB and 100GB (WD1200VE and WD1000VE)

Another two hard disk drives that we decided to include into our today’s test session are the two solutions from the Scorpio family from Western Digital. Two HDDs with 120GB and 100GB storage capacity are the biggest ones in the Scorpio family. They feature an 8MB buffer and their spindles rotate at 5,400rpm. The average seek time equals 12ms, and track-to-track seek – 2ms. The claimed average latency is 5.5ms. UltraATA interface boasts the theoretical data transfer rate of 100MB/s. These hard drives can withstand the operational shock of 300G, and non-operational shock of 900G. The size of these drives is also the same as that of the previous two models: 9.5 x 100 x 70mm, but these babies are heavier: they weigh 117g.

The hard drives support WhisperDrive technology using SoftSeek algorithm that reduces the level of generated noise during work. WD’s brand name ShockGuard technology protects the HDD mechanics and platter surface against physical damage caused by external shock. Another innovation from Western Digital is DuraStep Ramp that locks the HDD heads in a safe position when the drive is idle. The hard disk drive case is made of highly robust stainless steel.

WD1200VE is currently selling for around $180, while the smaller model, WD1000VE – for $135.

Testbed and Methods

The following testing utilities were used:

  • WinBench 99 2.0
  • FC-Test 1.0
  • IOMeter 2003.02.15

Testbed was configured as follows:

  • Albatron PX865PE Pro mainboard
  • Intel Pentium 4 2.4GHz CPU
  • IBM DTLA-307015 hard disk drive, 15GB
  • Radeon 7000 32MB graphics card
  • Microsoft Windows XP with Service Pack 2

The tests were performed with the generic OS drivers. The drives were formatted in FAT32 and NTFS as one partition with the default cluster size. In some cases mentioned specifically we used 32GB partitions formatted in FAT32 and NTFS with the default cluster size, too. During the tests the hard drives were connected to the Promise SATA150 TX controller with enabled Write Through mode.
