Full Review

The Western Digital Scorpio Blue WD7500BPVT is a 2.5-inch internal SATA II hard drive suitable for laptops, media players and other portable devices. It boasts a roomy 750GB capacity (a 1TB version is also available), a spin speed of 5400rpm and an 8MB buffer.

This internal drive is a big deal because of its high storage capacity, the maximum in the 2.5-inch space used to be only 500GB. This WD hard disk drive breaks through the barrier with its higher “areal density”. The WD Scorpio Blue WD7500BPVT wedges two 375GB platters together. Despite this, it remains a cool and impressively quiet performer. It is priced quite reasonably as well.

This WD hard disk drive breaks through the capacity barrier with its higher “areal density”.


The WD Scorpio Blue 750GB is compatible with standard 9.5mm notebook hard drive bays. This means it will fit in almost any laptop — in the past, most high-capacity drives were suitable for desktop replacement notebooks only. If you require lots of storage space while on the road and would prefer not to lug an external hard drive around, the WD7500BPVT is a compelling choice for upgrading your laptop’s storage capacity.

Compared to today’s desktop HDDs that consume at least 5 Watts on average, this laptop drive is rated to use 1.6W while active and 0.65W at idle, which is very good. Note that these numbers are averages as stated by the manufacturer, and actual power used could be as high as double the stated number at full stress. The Western Digital Scorpio Blue 750 GB HDD provides 698GB of usable space after being formatted.

We run synthetic benchmarks and real world tests using the fastest PC components on our test bench, to remove most bottlenecks that hold back performance. Read speeds averaged 88 MB/s with the speed graph peaking at the start and reaching its lowest towards the end of the chart.. Write speeds averaged 82 MB/s with a CPU utilization of 4 per cent. Random access times averaged 22 ms. In comparison, average desktop drives average 75 MB/s read, 60 MB/s write, and 12 milli-seconds random access time.

Real world write speed while copying a single large file of 6.42 GB onto this drive stood at 79.5 MB/s. Copying multiple smaller files (800 files totaling up to 6.36 GB) onto it fell to 34.4 MB/s. Copying multiple small files from one partition to another (intra-disk file transfer speed), was at 20.2 MB/s and for large files it was 32.6 MB/s. The reverse, copying large and small files from the WD drive onto our reference hard drive was at 86.9 MB/s and 60 MB/s respectively.

The WD Scorpio Blue WD7500BPVT remained quite cool during operation and it barely raised a purr. This is an important consideration for a laptop drive, as any sound emitted is usually noticeable. On the whole, we were pleased with the Scorpio Blue WD7500BPVT — it has plenty of storage, is reasonably fast and feels reliable. Western Digital offers a 3-year warranty.

Bottom Line

The Western Digital Scorpio Blue WD7500BPVT is a quiet and quick 2.5-inch hard drive for road warriors who need lots of storage on the go. Being able to store 750GB into this internal drive, is a barrier breaker of sorts, for data storage capacity.
However, the 1TB variant of this series might offer more value for your money. Also keep in mind the high access times, so if speed is of utmost importance on your laptop then you should look at an SSD instead even if drive capacity is lower on that side of the fence.
