Seagate Unveils New 2TB Hard Drive

More

Seagate began shipping the 2TB Barracuda XT hard drive today. The $299 drive costs more than other 2TB drives currently on the market, so there must be something special about it. The Barracuda XT operates on the next generation SATA platform, with speeds up to 6Gb/s, which translates to 768MB/s. This puts the drive much closer to the levels currently being attained by SSDs. However, users will need a motherboard that supports this new standard to take advantage of these speeds. The good news is that it is backwards compatible with the current SATA specification.

BillyBuerger on September 21, 2009 10:54AM Ummm, am I missing something here. The 6Gbps is for the interface between the drive and the motherboard. That has nothing to do with how fast the drive is able to read from the disk which doesn't appear to have changed. So this will in no way bridge the gap to SSDs which can exceed SATA speeds hence why some companies have put them directly on the PCIe bus skipping SATA altogether. reply to this

Zertz on September 21, 2009 08:41PM You are right, the 300 MB/s offered by SATA 3Gbps is enough for a HDD, but hey, they've got a world first and the bragging rights that come with it ;) reply to this

CheeseMan42 on September 22, 2009 02:27PM And yet you see people with SSD Raids that come close to or break 1 GB/s. Whatever is fast enough for you may not be for someone else. 300MB/s would be fast enough for me. reply to this
