Only a fool would put a SSD in a USB enclosure. Random read/write through USB interface is terrible compared to TB/SATA interface. The reason one would buy an SSD in the first place is for the amazing IOPS performance. If you're only interested in sequential performance, get two traditional HDDs and RAID them and you will get the same sequential performance as SSD, PLUS that you will have a ton of storage.
These stupid people who measures SSD performance with Blackmagic Disk Speed Test and what not are really starting to annoy me. It's the same retards who compares number of MP's in digital cameras and GHz's in CPU's.
Petsk, there is no one benchmark that will provide a user with an indication of what is best, because the benchmark has no idea how a particular user will use his computer and external storage.
You bring up one good point that few will understand - IOPS - the number of IO operations per second that can be instigated. Contrast that with thru-put which is what benchmarks like Blackmagic and AJA measure.
Some operations perform many, many transactions, each with a small amount of data transferred in each operation; web browsing or data base lookups. Other operations like streaming, which start a transaction, and access contiguous data; like streaming video or streaming audio. For streaming (whether audio or video), this is not very taxing at all, unless one is streaming uncompressed 4K HD video.
Video editing does expect fast contiguous transfers af large amounts of data. In complex editing systems, multiple HD streams may be in use. The faster the thruput, the more streams can be handled; if working with uncompressed video, even more bandwidth is required.
What is nice about a benchmark program is that it is an indicator of performance when comparing one device or interface to another. So for comparative purposes, almost any benchmark is useful. IS one benchmark the end all or be all. Of course not.
For the average user perusing the voluminous info here? Plenty to digest and to keep one occupied. But I advise everyone to look beyond the benchmarks, and look to what the benchmarks are really measuring, and to look closely at how you are actually going to use your computer.
