OCZ Summit 120GB SSD Review

Read Bandwidth

For this benchmark, HDTach was used. It shows the potential read speed which you are likely to experience with these hard drives. The long test was run to give a slightly more accurate picture.

We don’t put much stock in Burst speed readings and this goes double for SSD based hard drives. The main reason we include it is to show what under perfect conditions a given drive is capable of; but the more important number is the Average Speed number. This number will tell you what to expect from a given drive in normal, day to day operations. The higher the average the faster your entire system will seem.


Interestingly enough, the OCZ Summit with its older 1801 firmware is still faster in reads than the Corsair P64 with its more advanced 18C1 firmware. This is interesting and we have to wonder once again if 16 chips spread over the 8 channel based Sammy controller is the sweet spot for this controller vs. the smaller 64GB model with its 8 chips on 8 channels. Either that or OCZ has tweaked the basedfirmware, though judging by the lack of support from Samsung this is less likely.

Write Performance

For this benchmark HD Tune Pro was used. To run the write benchmark on a drive, you must first remove all partitions from that drive and then and only then will it allow you to run this test. Unlike some other benchmarking utilities the HD Tune Pro writes across the full area of the drive, thus it easily shows any weakness a drive may have.


If the read speeds were only mildly interesting, these writes are down right intriguing! Both the Corsair P64 and OCZ Summit use the exact same chips and the exact same controller…AND the Corsair has a more refined firmware YET it is handed a beat down by the Summit. Heck, these numbers are good enough to beat two of the three Indilinx based SSD we have reviewed in the all important minimum speed category.
