 Marvell 88SE9130 & HyperDuo

Marvell has just announced a new Serial ATA 6 Gbps controller, the Marvell 88SE9130. This additional chip, like its predecessors, is connected to a PCI-E 2.0 lane and offers two additional SATA 6 Gbps ports. It also supports a new technology called HyperDuo.

The concept of HyperDuo is simple: it combines an SSD with an HDD to get the best of both worlds. Both peripherals are visible as distinct volumes to the end user, with HyperDuo managing distribution of files to the SSD or the HDD according to how often they’re used. You can also chose where files go manually. Advanced users may well prefer to retain control of the distribution of their data and use the two distinct volumes as they please, bypassing HyperDuo.

HyperDuo works in two modes, with Safe Mode mirroring the same data on the SSD and the HDD. The capacity of the logical volume grouping the HDD and SSD then corresponds to the capacity of the HDD. Capacity Mode combines the capacities of the two drives into a single logical volume but without duplication of data.

HyperDuo works on the same principle as hybrid drives and extends it to two distinct peripherals. ASRock, ASUS, Gigabyte and MSI are likely to be using the 88SE9130 in forthcoming motherboards. It remains to be seen if the HyperDuo drivers will also support TRIM, something we’re still waiting to hear from Marvell on.

Note moreover that the future Intel RST 10.5 drivers are likely to integrate a similar technology, named RST SSD Caching.

 3 TB drives and the ASUS Disk Unlocker

A few weeks ago, ASUS announced the ASUS Disk Unlocker. Reserved for ASUS motherboards, this software allows you to unlock the space on a drive (depending on the manufacturer) beyond 2 TiB / 2.2 TB, at the same time as conserviting MBR type partitions. The attraction is of course being able to use drives that extend beyond this limit as your primary drive without losing the additional space and without requiring a UEFI bios and a 64-bit OS.

We tested it on a P5B Deluxe motherboard based on the P965, along with a Western Digital Caviar Green 3 TB (WD30EZRS) drive. We created an MBR partition of 2048 GiB on the drive. Disk Unlocker then allowed us to create a virtual drive of 746.52 GB, or the space unused on the drive, which it is then possible to use and format. Although an interesting feature, it remains fragile as on a PC without Disk Unlocker, the additional virtual drive won’t still be accessible. There’s nothing like native support!

 3 TB drives and Windows, practical test

As you know, the arrival of hard drives with higher than 2 TiB / 2.2 TB capacities poses a few compatibility problems, especially in Windows. You have to go from LBA type addressing to Long-LBA and MBR partitioning has to be abandonned for GPT.

To use such a drive as a secondary drive, Windows Vista and 7 are compatible, as is Windows XP 64-bit. Windows XP 32-bit doesn’t support these drives correctly.

To use such a drive as your primary drive, you’ll need to use either Windows Vista or 7 64-bit, as well as a UEFI bios.

What does this give in practice? We got our hands on a Western Digital Caviar Green 3 TB (WD30EZRS).
Secondary drive in Windows XP 32 bit
This configuration isn’t supposed to be supported… something we can confirm. Windows XP 32-bit SP3 only recognised a 746.51 GB drive in our case! Note that Paragon has announced a get around for this problem, but it won’t be free.

Secondary drive in Windows 7 32-bit
This time, Windows recognised the hard drive as having a capacity of 3 TB, or more exactly 2749.39 GiB (Windows displays in GBs but processes in GiBs). By using MBR partitions, you can create a first partition of 2048 GiB, but the remaining space isn’t usable. If you convert the drive to GPT, which requires the prior deletion of existing partitions, you can use all 2794 GiBs.

Primary drive in Windows 7 64-bit
To install and then boot on a drive using GPT, you need a UEFI bios and Windows Vista/7 64-bit. With a 32 bit installation DVD or without the UEFI BIOS, the partitioning will be in MBR and only 2048 GiBs will be usable. Although the drive is already partitioned in GPT, Windows will refuse to install anything over the top.

After activating the UEFI Boot option on the bios of our Intel DP55KG motherboard, the motherboard started in UEFI on the DVD and the installation took places in the standard way, whether in IDE or AHCI, and on a single 2794 GiB partition if desired (after having created a 2048 GiB partition then stretching it). If you deactivate the UEFI Boot on the motherboard after installation, the BIOS won’t be able to find a bootable peripheral.

 Hitachi en route to 5 TB!

Last week Hitachi announced a new 500 GB 2"1/2 hard drive running at 5400 rpm, the Z5K500. Nothing particularly new at first sight, except that this drive is just 7mm high and uses just one platter! It has a density of 636 Gb/inch², against 477 Gb/inch² for the previous generation.

Transposed to a 3"1/2 drive, such a density would allow platter capacities of 1 TB! 3 TB drives should then soon be replaced by 4 TB or even 5 TB versions from Hitachi, the only manufacturer to market 5 platter designs.

 Intel RST drivers

Intel has just updated its Intel Rapid Storage Technology drivers. In comparison to version 9.6, these drivers now support Long LBA type addressing which is required to support drives of over 2.2 TB. Up until now, the Intel drivers weren’t compatible with Long LBA addressing and we had to make do with the generic Microsoft drivers in AHCI mode. Note however that this support is currently limited to AHCI mode. We’ll have to wait for a future version for RAID support.

To recap, going beyond 2.2 TB poses compatibility problems as you have to go from LBA type addressing to Long-LBA and MBR partitioning has to be abandoned for GPT. In terms of the 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 boot on this GPT partition. 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.
