The Samsung 840 Pro SSD


Just as a chain is only as strong as its weakest link, a computer is only as fast as its slowest component. Although magnetic hard disk drives have come forward leaps and bounds in terms of storage density, reliability and size their performance improvement over the years has come nowhere close to matching that of other computer technologies such as CPUs.

You might have some of the most powerful CPUs and GPUs on the planet in your workstation, but they’re nothing but expensive paperweights if all they do is wait to be fed with data. For many high-end computing applications mechanical hard drives are just not up to the task of keeping the pipes fed and this is where SSD technology comes in.

SSDs or Solid State Drives have no moving parts and consist entirely of electronic memory similar to RAM or thumb-drive flash memory. Because it’s completely electronic it isn’t hampered by the same laws of physics that hold back mechanical hard drives, such how fast a platter can spin or a read-write arm can move. Since SSDs are a relatively new technology, they are still more expensive and don’t offer as much storage when compared to mechanical hard drives. They are however catching up fast.

At TitanUS we recommend the Samsung 840 Pro SSD to most of our clients as an exceptional mix of performance and value.

Starting at 64GB, the 840 Pro is available in capacities up to 512GB. With a current price-per-GB ratio that ranges from $0.70 to about $1 the 840 Pro is not unreasonably priced. The SSD uses the SATA 6Gbps interface. Sequential read speeds have been measured at 540 Mbps and sequential writing at 450 Mbps. These are top-tier figures and ideal for sequential tasks where data is fed in a predictable way.

In addition to this the 840 Pro is very light and thin, measuring at only 7mm thickness, which also makes it a great option for one of our high-end Mobile Workstation Laptops. It’s low power consumption and heat generation extends battery life and for desktop workstation computers decreases strains on PSUs while saving on the electrical bill.

Because of the great value for money the 840 Pro drives represent, you can get over the issue of relatively small capacities by installing multiple drives or configure these already phenomenally fast drives into a RAID configuration that will see truly amazing sequential read figures.
