 Seagate Barracuda LPs go Green

Seagate has just announced that it's renaming its range of 5900 rpm hard drives. The old Barracuda LPs will now be called Barracuda Green. At the same time, the manufacturer is launching two new 1.5 and 2 TB models, the ST1500DL003 and ST2000DL003.


In comparison with the previous generation, they’ve moved over from the SATA 3 Gbits interface to SATA 6 Gbits and the cache goes from 32 to 64 MB. Advanced Format 512e (4 KB physical sectors with 512 byte emulation for the system) is used and they're higher density as these two new models have 3 double-sided platters, or 500 and 667 GB per platter.

In terms of performance, the figures given by Seagate are pretty crazy, going from 95 to 144 MB/s in continuous speeds… but also with latency of 4.16ms instead of 5.1ms. The figures given for latency are directly linked to the speed of rotation and correspond to a 7200 rpm drive and not 5900 rpm, which calls the announced rotation speed into doubt, itself unusually high.



 Hitachi Deskstar 7K3000 & 5K3000

Hitachi has just announced its new generations of SATA 3"1/2 hard drives, the Deskstar 7K3000s and 5K3000s. With 7200 and 5400 rpm rotation speeds respectively, they have a maximum of 5 platters and are to be available in 1.5, 2.0 and 3.0 terabyte versions. The PC interface is SATA 6 Gbits type, with 64 MB of cache for the 7K3000 and 32 MB for the 5K3000.


To recap, beyond 2.2 TB there are compatibility issues as you have to go from LBA type addressing to Long-LBA, and MBR partitioning has to be abandoned for GPT. In terms of a system disk, this makes it necessary to have a recent 64-bit OS as well as a motherboard with an EFI type bios so that Windows can start. For a secondary disk, you don’t need a 64-bit OS or an EFI bios, but Windows XP won’t be compatible. Hitachi has published a quite thorough datasheet on the subject.



 2.5 and 3 TB from Western!

Although Seagate had already announced a 3 TB hard drive, it was designed for external use. Today, Western has launched two new internal 2.5 and 3 TB hard drives, the WD25EZRSDTL and WD30EZRSDTL. Announced at $189 and $239 respectively, these drives are not without the odd compatibility problem.


Upwards of 2.2 TB, you have to move over from LBA type addressing to Long-LBA and MBR partitioning has to be abandonned for GPT. In terms of a system disk, this means you need a recent 64-bit OS as well as a motherboard with a UEFI type bios, and this is pretty rare.

Western are also including a PCI-Express controller card that supports this type of drive in the bundle with the drives, which makes you think that the drivers of the most common chipsets don’t yet necessarily do so.



 750 GB on a 2''1/2 from Hitachi

Following Toshiba and then Western in March, it’s now over to Hitachi to launch its 2"1/2 hard drives with a 750 GB capacity, in spite of the use of two platters at the standard height of 9.5mm.


The Travelstar 5K750 and 7K750 both use 4 KB sectors (Advanced Format) and run at 5400 and 7200 rpm. Their respective caches are 8 and 16 MB. The 5K750 is currently being delivered and should be available in shops as of November in a bundle for $129.99.

The 7K750 will arrive a bit later and will be sampled at some point between now and the end of the year, for availability in the first quarter of 2011.



 Roundup: twelve 1 TB hard drives!

After publishing our report on 2 TB drives, we’re throwing ourselves back into the breach with a selection of 1 TB drives! More common, these drives have been on the market since 2007, the first manufacturer to sell a drive at this capacity being Hitachi with the 7K1000. At the time the 7K1000 1 TB used no less than five 200 GB platters. Things have changed somewhat since then and the 1 TB drives in 2010 have three 333 GB or even two 500 GB platters...
