Average Bench: 81.1% (454th of 1058)


The Toshiba HG5d is a reasonable SSD. Considering that Toshiba is amongst the few manufacturers that produce both their own NAND flash and SSD controllers, the HG5d is a little disappointing. With a Real World Speed of 444 MBps the Q Series lies just above the 50th percentile. Relative performance is better for server orientated workloads where the HG5d scored an AS SSD Total score of 970 points putting it in 11th position and at the 66th percentile, additionally the HG5d demonstrated very strong mixed 4K transfer rates peaking at 51.1 MB/s, the second highest seen to date on a 256GB SSD. The Toshiba HG5d is not a bad SSD but neither is it cutting edge which given it's relative youth counts strongly against it. Overall there are both faster and cheaper deals to be had elsewhere. [Sep '13 SSDrivePro]

The only problem was I have had to reformat the drive 2 times random loss of of boot sector. I have 2 of them 1 is perfect the other needs formatted every 6 months or so. No firmware updates not much info from Toshiba at all.. Toshiba wont replace it because they cant find anything wrong with it. I even switched computers and the problem followed the drive not the pc. One pc is a laptop the other is a desktop.—Apr '15
