KingFast F3 Plus Series Specifications
The KingFast F3 Plus Series SSD features an impressive endurance specification of 6,000 TBW for the 60GB model and 12,000 TBW for the 120GB model. There is no information on how these endurance numbers were obtained, but with SLC, it is certain that the F3 Plus will offer up plenty of endurance for users.
The KingFast F3 Plus features sequential read/write speeds of 556/530 MB/s, respectively. The random read IOPS are 55,735 and random write weighs in at a higher 83,221 IOPS. These are FOB (Fresh out of Box) numbers with 100% compressible data. We will test the steady state performance with 50% compressible data in the following pages.
Power consumption is rated at .3W idle and 2W under a heavy random 4K write workload. These seem to be very optimistic power consumption figures for a heavy write load, and we will put this to the test in this evaluation.
The KingFast F3 Plus sports 55b/512 BCH ECC and enabled R.A.I.S.E functionality to protect user data. There are no capacitors for data hold up with the F3 Plus, but for LSI SandForce powered SSD's power hold-up features aren't as important as with controllers that utilize DRAM caching.
Forgoing the use of a DRAM cache simplifies the construction of the SandForce SSD's, but also helps to eliminate much of the damage with unexpected power loss. LSI SandForce SSD's have a 1 in a 1,000 risk of losing data during a power loss event. While this does not entirely negate the need for supercaps, there is less risk in operating without power hold-up due to the inherent DRAM-less design of the LSI SandForce controllers. The addition of LSI SandForce compression algorithms reduces the wear on NAND during the life of the SSD. When combined with SLC flash this should create a superior SSD in terms of endurance and durability.
Surprisingly the KingFast F3 Plus only features a three year warranty. With many MLC SSD's from the current crop of contenders warrantied for five years, we feel that this SLC SSD should have a longer warranty period.
