The 120GB Kingston HyperX 3K is nearly two years old, several generations of SSD have passed since its original release. Better 120GB SSDs have more NAND modules than the old HyperX and are able to write faster than the peak 234 Mb/s achieved by the HyperX 3K. The HyperX 3K also has a Sandforce 2281 controller which is unable to write compressed data as well as its more recent competition. All that said the HyperX still has an effective speed of 367 MBps which is respectable and far faster than even the best mechanical drive. With peak 4K read/write speeds of 33/110 MB/s the HyperX 3K also has competent small file performance. To summarize as a current value proposition the HyperX 3K struggles, simply because the likes of Samsung and OCZ have innovated and moved forward in the two years since the HyperX 3K was released. [Feb '14 SSDrivePro]

18 months in it's still running, and seq read speeds remain decent (mid 400's) but seq write speeds have dropped to around 175 avge. It's got 9K power on hours, so fairly heavy use. It's an underwhelming drive that'll get you a year and a half of OKish speeds, then it's relegated to your girlfriends friends laptop for $20 :)
