WD Blue series 7mm drive would be a comfortable choice for those upgrading their notebook storage. There’s really nothing much to be said, but slimmer 2.5mm drives are 7mm z-axis height. Some 7mm thick drives were reviewed in the past, and there are many uses such installing them on an Ultrabook or pretty decent alternative to installing in a cramped desktop unit.
As usual, performance is what will be observed here.
The only keyboard here the decrease of the thickness of the notebook drive from the common 9.5mm to 7mm. If its 7mm, it means its a drive one could consider for ultrabooks and certain units where you want to use slimmer drives for whatever reasons you have.
That being said, it’s a 500GB drive with a single platter. It comes with 8MB Buffer Cache.
The drive is limited to 5400RPM, as one would expect for a “Blue” branded drive.
I wasn’t able to open the PCB because of one of the Torx screws didn’t have any “edges” for some reason, but it uses the same old trusty Marvell 88i93460TFJ2 and Samsung K4T28163QP-BCE7 buffer chip.
These drives come with a usable space of 465.8GB.
It gives me great pleasure every time I put up a review. It’s always good to appreciate the support that the manufacturers give from time-to-time to review their own products and others on behalf of the readers. Thanks to companies such as Asus, Gigabyte, Kingston, WD and Coolermaster who give me hardware support by updating my test rig no strings attached. Thumbs up to these guys!
I would like to thank
- Gigabyte India for providing Gigabyte 890GPA UD3H Rev 1.0 motherboard
- Asus India for providing Asus 990FX Sabertooth motherboard
- Kingston Taiwan for providing hardware support with memory kits and SSD drive.
- WD India for providing WD 300GB HLFS Velociraptor Hard Drive.
- Coolermaster India for providing Coolermaster GX450 RS-450-ACAA-D3 Power Supply

The Benchmarks that I am using are as follows:
AS SSD– Read and Write (Pass 3)
ATTO- Test File Size= 0.5 to 8MB- Read and Write Pass 3
Aida64- Write and Read Access time File Size 64KB Pass 3
Anvil Benchmark- Compressible and Incompressible run each with 4, 16 and 32MB File Size
Boot Load Test- (Windows 7 SP1 clean installation with AMD 12.6 drivers+ AHCI drivers pre-installed with Utorrent, Avira Security Suite, Asus Xonar DX+ 22.214.171.1244 Drivers, Netgear WG111 Wireless LAN USB drive software as start-up items) Pass 1-5 (Pass 1= System start from Power Off)
CrystalDisk Mark Benchmark- with Pass 3, each with 5 re-runs 1000MB File Size
HDTune Pro- Write and Read Pass 3
PCMark 7- HDD test
PCMark Vantage- HDD Test
Anvil Benchmark- 4/16/32GB File Size in both 0% and 100% Fill test
Although this test is used for SSDs, the tests in these give a good idea of Sequential, 4K Aligned, 4K Aligned with 64Bit thread test and the Access time of the hard drive using incompressible data.
The drive’s 4K runs stand toe-to-toe with Seagate’s Momentus XT ST750XL003 and WD’s Scorpio Black WD750BPKT drive. Read access is a little bit on a higher side.
WD’s Scorpio Blue WD6400BEVT still has an impressive 4.672 MB/s write access speed, in comparison to 7mm 500GB counterpart which stands with +10MB/s.
With a transfer sizes from 0.5KB through 8192KB and a total length of 256MB, ATTO measures transfer speed throughout the drive’s storage capacity for both reads and write.
As you can see here, the drive is maxed out from file size 16MB onwards. Maybe- just maybe- if this was a 7200 RPM unit, it could have better results.
When compared to the already tested drives, WD Scorpio Blue is second to Black WD7500BPKT. Momentus XT 750 does have an upper hand over this drive from 0.5 to 8MB, but that’s about it.
But when it comes to write speeds, this drive has an advantage over previously reviewed drives all the way through!
Windows 7 SP1 clean installation with AMD 12.6 drivers+ AHCI drivers pre-installed with Utorrent, Avira Security Suite, Asus Xonar DX+ 126.96.36.1994 Drivers, Netgear WG111 Wireless LAN USB drive software as start-up items) Pass 1-5 (Pass 1= System start from Power Off
Ignoring the SSD drives, It’s only both the Momentus XT drives that have the advantage over WD Blue versions. This is where the read-only flash NAND comes in handy- Application loading and Windows boot-up. If WD does the same, it could work much better than what you see now. Still, the 7mm slim drive has over the rest of the drives.
The strongest point in this drive is the write speed.
The drive comes with 2 years warranty. It is not too expensive and it does provide good enough space for the price. As slimmer notebooks are sold for a while, you will need to have 7mm slim drives. Of course, as time passes we will see higher capacity 7mm 2.5″ drives. But this is where we are right now. The WD Blue 7mm 2.5″ HDD is recommended as a cost-effective upgrade option. It would be nice to see a spacer bundled with it for those notebooks with larger z-axis storage height.
