REVIEWS / Internal Hard Drive Reviews
Our test set-up:
- Intel Core 2 Duo E4300
- MSI P35 Diamond Motherboard
- 2 GB OCZ Platinum EB DDR3-1600 RAM
- Antec Sonata Designer Case
- 2x Western Digital Raptor 74 GB RAID 0
Once the disk's in place, we test data transfer speeds, plus noise and temperature management. We then check our results by running a series of benchmark tests for comparison.
We'd like to thank BeHardware.com for helping us put together our internal HDD buyer's guide. Full reviews of the SDDs and HDDs featured in our guide can be found at:

What to look for
Ideally, we'd recommend using a mix of the two types of technology—a decent-sized SSD (128 GB, for example) for your system and most frequently used applications, alongside a 'Green' edition HDD with low noise levels for storing multimedia files (photos, videos, etc.)
Here are a few things to look out for when shopping for an internal storage solution.
- Performances. This can be quite confusing. You can obviously look at the read speeds and write speeds (in Megabytes per second, MBps), but access times are important too. For hard drives, this is usually given in milliseconds (ms), while for SSDs, which are much faster in this field (up to 150 times, in fact!), it's more common to see the number of operations per second in read or write mode (input and output operations per second). The thing to bear in mind is that for most general users, 'read speeds' are more important. Plus, most SSDs will be pretty much equivalent for day-to-day use.
- Storage capacity. Storage capacities are given in Gigabytes (GB) or Terabytes (1 TB = 1000 GB) and are generally the first thing people look for. These numbers tell you the amount of data that can be stored on the drive. Hard disks do better than SSDs on this front, with up to 3 TB of memory compared with a maximum of 512 GB for SSDs. An SSD will also be more expensive than an HDD of equivalent size.
- Noise. SSDs are very quiet. Noise output from HDDs varies but, generally, the higher a drive's performances, the noisier it'll be. For a system drive, we'd look for a 7200 RPM spin speed, while for a secondary HDD for storage, we'd go for a 5400/5900 RPM model. The spin speed determines a drive's basic noise level, which will then get louder when the drive accesses data.
- Reliability. Unfortunately, there's no way of telling how reliable a drive will be. Some people say that SSDs aren't as reliable as regular hard drives, but as far as we're concerned, SSDs are perfectly reliable, and often more so than HDDs! They can resist drops and falls too. Whichever drive you pick though, make sure you back up any important files!
