Random Read Performance
The 1TB Toshiba BG4 delivers over 14,000 random read IOPS at QD1. Anything over 10,000 is really good and makes for a pleasurable user experience. The 14,000 IOPS mark is higher than any other drive we've tested with Toshiba TLC memory to date.
Random Write Performance
DRAMless SSDs always struggle with random write performance, and the BG4 doesn't break that rule. The drive doesn't trail the others too far at low queue depth where consumer workloads reside. It could be better, but we're not going to complain too much because many decent SATA SSDs struggle to hit these numbers.
