from the my-first-hard-disk-had-40-MB dept.

Japanese manufacturer Fixstars is releasing a 6 terabyte 2.5" solid state drive in July. The drive uses 15nm MLC NAND. 1 TB and 3 TB models are also available, but only the pricing for the 1 TB model is known: $820. The drive is not particularly fast; it uses the 6 Gbps SATA 3 interface to achieve 540 and 520 MB/s sustained read and write speeds.

For comparison, the highest capacity 2.5" hard disk drive is currently Toshiba's 3 terabyte MQ03ABB300, which uses four 750 GB platters. The Fixstars SSD is 9.5 mm thick, while the Toshiba HDD is 15 mm thick.

It's about time to bring the HAMR down.

    Because memory sockets vary way more than S-ATA. And if you pick up random computer. Chances you find a S-ATA connection is way higher. And if you don't, there's a lot of adapters.

    Granted that just about every computer has SATA. But I would expect that by now, the storage industry would have come up with a connectivity specification that was optimized for flash.

    Consider that rotating media can only read the bits that are passing under the head. If you want to read a whole sector, you have to wait for the disk to rotate a little bit.

    Modern memory controllers can read and write data in much wider chunks then the CPU registers, for example my Core Quad Xeon e5420 access four FB-DIMMs in parallel, to load a cache line all in one go.

    There should be a connection standard that works like that for flash.

      Industry and coming up with a smart solution. No that doesn't happen particularly fast. So until that happens, expect to wait and suffer.

      (USB is an industry creation.. and it really suck when it comes to smart design)

      There were PCI-e based SSD drives, but from what I heard these were not terribly reliable. But really I don't think SATA is the problem here. I believe the current SATA spec is still faster than the fastest SSD drives.

      USB certainly isn't the solution. It is no where near reliable enough for permanent storage on a computer.

      RAM sockets are not really it either. The way the computer interacts with RAM is much more different than permanent storage.

      It's called NVMe. It can allow SSDs to read/write more than 2 GB/s.

      There's a reason I wrote that this 6 TB drive is "not particularly fast", and it's called NVMe.

        Yeah, PCI-e is probably fast enough to make a serious difference. And it's a standard to. Otoh.. perhaps not much faster than S-ATA. BUT it can be utilized with many parallel channels.

          The fastest SATA is 6 Gbps. PCIe3 is 8 Gbps per lane. An x16 slot is 128 Gbps. PCIe4 will be twice as fast as PCIe3.
