A head assembly on a Seagate disk drive by Robert Scoble (cc) (from flickr) I was reading about pythons becoming an invasive species in the Florida Everglades and that brought to mind SSDs. The current ecological niche in data storage has rotating media as the most prolific predator with tape going on the endangered species [...]

Today Seagate announced their new SSD offering, named the Pulsar SSD. It uses SLC NAND technology and comes in a 2.5″ form factor at 50, 100 or 200GB capacity. The fact that it uses a 3GB/s SATA interface seems to indicate that Seagate is going after the server market rather than the highend storage market [...]

Hard drives have been on a capacity tear lately what with perpendicular magnetic recording and tunneling magnetoresistive heads. As evidence of this, Seagate just announced their latest Barracuda XT, a 2TB hard drive with 4 platters with ~500GB/platter at 368Gb/sqin recording density. Read-head technology limits Recently, I was at a Rocky Mountain IEEE Magnetics Society [...]

The above chart shows the top 12 LRT(tm) (least response time) results for Storage Performance Council’s SPC-1 benchmark. The vertical axis is the LRT in milliseconds (msec.) for the top benchmark runs. As can be seen the two subsystems from TMS (RamSan400 and RamSan320) dominate this category with LRTs significantly less than 2.5msec. IBM DS8300 [...]

Recently, the Storage Performance Council (SPC) has introduced a new benchmark series, the SPC-1C/E, which provides detailed energy usage for storage subsystems. So far there have been only two published submissions in this category but we look forward to seeing more in the future. The two submissions are for an IBM SSD and a Seagate [...]
