The same leading review websites typically claimed "extremely fast" speeds when speed differences between the fastest drives and the slowest drives tested for comparison were something like 5% or 10%. Most of those adjectives were added not necessarily because they were fast, but because they were 10x more expensive.
By "extremely slow", I tend to mean something like 1,000% or 1,000,000%.
New, unfragmented SSHD and HDD drives of the newest generation are able to read and write at under 1,000 IOPS.
I can quote literally thousands of examples where reviewers from each of the very popular tech websites chose to use 1,000 times bigger hyperboles of mine, but that will require hundreds of separate posts.
Here's the specification of Seagate 500GB SSHD.

â—¦DRAM Cache 64MB
â—¦Average Data Throughput 100 MB/s
â—¦PC Mark Vantage Average HDD Score: 19,838
â—¦Average Windows 8 Boot Time <10secs
â—¦Seek Average, Read <12ms
â—¦Seek Average, Write <14ms
Here's MyCE Toshiba 1TB SSHD review published two months ago.
SSHD works like HDD, not SSD, though a little faster than conventional HDD. A Toshiba 1TB SSHD for US$130 may sound cheaper when a Samsung 1TB SSD costs US$580, but a deal on MyCE mentions 3TB conventional HDD for US$100 even including a USB 3.0 case and shipping cost. Since it's easy to buy 120GB SSD for under US$100, that makes 120GB SSD plus 3TB USB 3.0 HDD for under US$200, a bit higher than Â£100 (about US$160), but a lot faster and a lot bigger.
Benchmark test speed of unfragmented sequential write speeds of 10GB video files does not really count when the user wants to have one drive only in one system for both booting and storage of data files.
