Think 2.5-inch spinning hard disk drives are slow compared with the solid-state variety? Not always, Toshiba seems to be saying with today's announcement of drives that top 10,000rpm.

Toshiba launched four 2.5-inch HDDs, ranging up to 900GB in capacity, that boast speeds of 10,500rpm.

That's faster than the 5,400rpm and 7,200rpm 2.5-inch HDDs typically found in laptops.

The internal transfer rate for Toshiba's AL13SEB900 family of HDDs is 286 MB/s (megabytes per second), a boost of approximately 32 percent over the previous generation of drives "due to improved liner recording density," according to Toshiba.

Though slower than the fastest solid-state drives on the market, that kind of transfer rate approaches some less-expensive SSDs in speed.

Power consumption is also improved -- approximately 41 percent better than the family of drives the AL13SEB900 succeeds, Toshiba said.

Toshiba is marketing the drives to corporate "enterprise" server customers -- but that doesn't mean consumers can't get their hands on one.

Volume shipments will begin in August. No word on pricing yet.
