Specifications, Pricing and Availability
Offered in three capacity sizes and two form factors, the Kingfast F8 Series 2.5" drives use the new SATA III JMicron JMF667H controller, and pair it with 128MB DRAM. From the ground up, this product is built to deliver high value and performance, and at least on paper, appears unimpressive. Kingfast quotes sequential read performance at just 427 MB/s, and sequential write performance at 241 MB/s; hardly the performance you would expect TweakTown to get excited about. I think Kingfast quoted performance from the 64GB or 128GB model, because in our testing we topped out at just over 510MB/s sequential read, and 370 MB/s sequential write.
Looking at the specifications sheet, we had other concerns as well. The random read performance looks solid for a budget drive, 74K read IOPS, but the specifications sheet shows just 1,555 IOPS for random writes. Although that is higher than a 10K spinner on its best day, it's not very SSD like, and thankfully in our tests we achieved over 30K at queue depth 1, and just under 60K at QD32. I'm not sure who put together the specifications sheet I found, but I'm sure their foot is still bandaged, and someone needs to keep them away from firearms.
Specification mismanagement doesn't stop there. The specific model number for the drive we're testing today is KF2510MCJ09, and if you go to Kingfast's website, it's nowhere to be found. The 7mm z-height variant of the same drive is available, and for just a few dollars more. Google turned up a number of Chinese Amazon type wholesale outlets where Kingfast lists the drives for sale; that doesn't do much for consumer confidence. I have heard of Ali Express before, but I haven't purchased anything from the site before. Alexa shows it as the 78th most trafficked website in the world at the time of writing, so the site is popular globally, just not by me I guess.
There's little reason to look at the specification sheet any further since we don't know what's accurate and what's not. We'll pull the performance numbers ourselves anyhow. The drive ships in a blister pack without accessories, software, adapter bracket, or any of the pieces we expect to come with a premium product. It does carry a three-year warranty.
