![]() ![]() There appears to be a direct correlation between a latency nearly twice as high as any other drive and calculated bandwidth that's half as fast as the rest. Once again, much higher latencies are the Swordfish and Falcon's Achilles' Heel. Here, we used the Quick System Drive storage benchmark, which puts the drive through its paces in a scripted 20-minute run of several different disk-oriented tasks. PCMark offers a trace-based measurement of system response times under various scripted workloads of traditional client / desktop system operation. We like PCMark 10's new quick storage benchmark module for its real-world application measurement approach to testing. Even when all of the drives are handicapped by a low queue depth, the ADATA drives fall behind. It's disappointing for the Falcon, however, since its more premium pricing should exclude it from this kind of uneven performance. Whatever the cause, we feel we can somewhat forgive the Swordfish considering its budget-level price and the relative performance of similarly-priced SATA drives, which is much lower still. This could be a result of the higher seek times we saw in HDTune Pro. In that test, the ADATA drives not only took a performance hit compared to their rated specifications, but could only muster performance of roughly one-third of their competition. The Q1 test is much closer to the behavior of a typical client desktop scenario, though, and the drives still performed pretty much up to expectations. Both the Falcon and the Swordfish performed up to their theoretical maximum performance on the heavily threaded Q32 test. The sequential tests went quite nicely for all of the drives involved, including our ADATA test subjects. It provides a quick look at best and worst case scenarios with regard to SSD performance, best case being larger sequential transfers and worse case being small, random transfers. ADATA told us that a firmware update for both drives would appear soon in the SSD Toolkit to address some performance oddities we've seen, but as of this publication, that hasn't happened yet.ĬrystalDiskMark is a synthetic benchmark that tests both sequential and random small and mid-sized file transfers using incompressible data. HD Tune uses the full capacity of a drive and requires the drive not be partitioned to run, so it's not a file system problem. We're not sure what the Falcon is doing, but it kept this kind of sawtooth performance throughout multiple runs, even after a Secure Erase in the ADATA SSD Toolbox and letting the system sit idle for 90 minutes. Left: ADATA Falcon, Right: ADATA Swordfishīoth the Swordfish and the Falcon advertise SLC caching for improved write performance.
