Final Thoughts




Even though the Intel SSD 5 545s doesn't show us the true potential of Intel's second generation 64-layer 3D flash, it does give us a taste of what is to come; and it tastes good. The Intel SSD 5 545s is one of the best performing SATA SSDs we've ever tested. The reason we are of this opinion comes down to the most important performance metric - random read performance at low queue depths. In this regard, the SSD 545s is a cut above the competition as shown by our Anvil's testing. Whenever a SATA based SSD delivers random performance of over 10,000 IOPS at 4K QD1 read, it is indeed something special. The 545s cranked out an earth shattering 13,800 IOPS at QD1 and additionally delivered the best random read performance we've ever seen from a SATA SSD at QD1-4 when testing with Anvil's.



Of course, this stellar low QD random read performance translates to awesome workload performance. The 545s delivered the goods in our Vantage testing and again in our PCMark 7 testing with massive performance improvements over the drives in our test pool that are running on first-generation IMFT 3D flash.


With the introduction of 64-layer TLC flash, the days of planar flash and MLC flash are quickly coming to an end. 64-layer TLC flash is set to dominate the consumer SSD landscape for the foreseeable future because it promises lower cost, higher capacity, higher endurance and yes, better performance than anything to date.


The SSD 5 545s doesn't have Samsung running for the hills just yet, but the SSD 5 545s wasn't intended to be an EVO killer; just better than most and more affordable. In this regard, the SSD 5 545s hit its intended target. With an opening MSRP of $179.00 and legendary Intel quality, we see the potential that it may give Samsung something to worry about in the near future.


User Experience: In the end, it all comes down to user experience. The SSD 5 545s boots like lightning, launches programs in the blink of an eye and most of all provides consistent performance that is seemingly unaffected by normal consumer workloads that can bring lesser TLC SSDs to their knees. The SSD 5 545s delivers a true tier-one SSD experience that is sure to please, which is why it is TweakTown recommended.
