The main difference is that HyperX is with 5K P/E cycle version whereas HyperX 3K comes with 3K P/E cycle like how Force GT does. For an end-user, unless you’re workload has a lot more workload compared to gamers, enthusiasts and such users, it doesn’t matter. What matters is the price and performance. This should also explain why Kingston HyperX 120gigs retails for approximately Rs. 1,000/- more than Force GT.
If this was a 120gig version, it would have mirrored most of the benchmarks with HyperX and Force GT easily. Still, for a 90gig drive, this is a very good drive to shortlist. You still get 3 years warranty that Kingston gives on the 5K counterpart.
So now, it comes to cost.
Kingston HyperX 3K 90GB Standalone Kit
Do note that the official pricing for 90GB HyperX 3K Standalone kit is Rs. 8,500/- so the street pricing, once its listed on online stores, should most likely be significantly lesser than Force GT counterpart.
The conclusion is clear: This a 90gig version drive that gives you a formatted space of 83.8GB with 3 years warranty support which can somewhat stand between Corsair Force GT and HyperX with 5K P/E Cycle, both being 120gig version- and one of the best SSDs to shortlist.
