Western Digital WD Black² 2.5-inch Dual Drive (SSD + HDD)

My older system is Serial ATA-1.5 and one of the oldest SATA standards: “First-generation SATA interfaces, now known as SATA 1.5 Gbit/s, communicate at a rate of 1.5 Gbit/s, and do not support Native Command Queuing (NCQ). Taking 8b/10b encoding overhead into account, they have an actual uncoded transfer rate of 1.2 Gbit/s (150 MB/s). The theoretical burst throughput of SATA 1.5 Gbit/s is similar to that of PATA/133, but newer SATA devices offer enhancements such as NCQ, which improve performance in a multitasking environment”.
What this proves is even with the oldest SATA standard a user can expect big improvements.
  • ATA Rev. 1 – 1.5 150MB/s (this review)
  • ATA Rev. 2.0 300MB/s
  • ATA Rev. 3.0 600MB/s
  • ATA Rev. 3.2 1969MB/s

The newer the ATA Revision the better expected performance.

HD Tune Original WD Scorpio Blue HDD shows minimum 1.2MB/sec, max speeds of 67.5MB/sec and average 47.9MB/sec. for the old HDD.

Minimum 1.2MB/sec, maximum 67.5MB/sec and average 47.9MB/sec. for the old HDD compared to 55.6MB/sec, 178.9MB/sec and 95.6MB/sec. three times the average overall increase.
Let’s compare the original WD Scorpio Blue HDD to the new WD Black HDD.

The WD Scorpio Blue provides transfer rates around 60MB / Sec read and 55MB / Sec writes.

Comparing the original 60MB / sec read and 55MB / sec writes to the new 105+MB / sec I’d say we can expect about twice the performance for HDD work.

Hidden away in a dark part of the Modders-Inc offices is a man, no a machine, that writes reviews so epic that they have been listed in the top ten best reads by the New York Times. Well that is what we tell him otherwise we have no idea what would happen if he knew the truth.

  1. 20 days now since I did this upgrade to the wifes old laptop.
    Every night she sits down, hits the power button, I look at her, she at me and I get the sweetest smile.
    As a client she’s very happy with the improvements. ALL of the complaints have stopped and replaced with :)
