Following a recent announcement of a partnership between Seagate and LSI, LSI announced the bootable SSS6200 PCIe form factor solid state storage solution. Capacity is initially targeted at 300GB, scalable up to 1TB as flash technology evolves. The 300GB solution operates within the PCIe power envelope of 25W. In addition the front-end is PCIe 2.0 […]

SSDs – Impact on System Level Capacity and Performance

Both Facebook and MySpace are now using Fusion-io Solid State Storage to address the performance challenges of Social Networking. As James Hamilton notes in his Perspectives blog entry Scaling at MySpace social networking are difficult to implement. He calls them “hairballs” because the many-to-many relationships are difficult to partition and scale. Massive daily growth of […]

Latency – Where are we headed?

As a follow-up to “Latency – How far have we come in a decade“, I thought it would be useful to add the recent Solid State Storage data to the mix. As already discussed under SATA SSD Product Announcements, there are several SATA SSDs available, from consumer up through enterprise class. The advantage of SATA […]

SSDs – Buyer Beware?

The latest wave of product releases is revealing some interesting aspects of SSDs. You have to read beyond the headlines to find the nuggets. Let’s look at one nugget derived from various articles:

Seagate ‘Pulsar’ is spec’ing 4K random reads of 30,000 IOPs while sustained 4K random reads range from 10,500 IOPs down to 2,600 […]

More SSD Partnerships Announced – LSI and Seagate
