Toshiba BG4 1TB SSD Review


The 1TB BG4 is rated at up to 390,000 IOPS for 4K random reads. Unfortunately with our 4 threaded tests we couldn’t get close to this maximum figure, the best we got from the review drive was 247,013 IOPS.

4K Random Read v QD Performance

At shallow queue depths the BG4 languishes at the bottom of our results charts, but the performance improves noticeably at a QD of 32 and it moves up the chart.
