    SATA roadmap for laptop drives

    Thanks. Given that M.2 does both SATA and PCIe busses, I'm also concerned that it will gradually gravitate towards the faster PCIe bus. My application is SATA only, so I'm also trying to avoid running into a situation where there are no M.2 devices that speak SATA anymore in 5-10 years. What are the chances of this?

    SATA roadmap for laptop drives

    Good point. I'm however more concerned with the availability of mSATA drives, rather than whether they'll be widely used in the PC/laptop market. I'm developing a system that will ultimately make use of a small form factor SATA device, and I'm trying to figure out whether to use mSATA or M.2, hence I wish to know if mSATA drives will still be available in the next 5-10 years. Performance isn't a big issue here, mSATA SSDs are fast enough.

    SATA roadmap for laptop drives

    Hmm, I still see mSATA in many SSD manufacturer's product card. For example, Samsung 840/850 series still have mSATA versions. I still see mSATA in some companies roadmaps all the way up to 2017. Hence, I'm curious as to when availability of mSATA products will be close to nil, much like the case for the 1.8" microSATA form factor now. I have an application that uses SSD, and I have a choice right now to support a tried and tested mSATA, or an untested and fragmented M.2, so I'm weighing the pros and cons.

    SATA roadmap for laptop drives

    Thanks. In terms of availability, how long do you think mSATA has before it reaches EOL status? Also, it seems that M.2 is currently quite fragmented in terms of the the various types available. I see differing physical sizes, and different protocol standards (SATA/AHCI vs NVMe). Is NVMe even compatible with SATA controllers? Will M.2 continue supporting both SATA and NVMe or will it move towards NVMe in the future?
  5. Hi, I'm trying to get a sense of the current and future landscape for laptop SATA drives. AFAIK, currently the standard is 2.5" SATA, along with mSATA and sometimes M.2 drives. It also used to be 1.8" microSATA, but that standard has largely died out. Does anyone have any figures on the different percentages of these standards among various PC laptops (excluding Macs)? Will M.2 drives replace mSATA in the near future like mSATA replaced microSATA? Thanks!
  6. Hi, I have a requirement for a large capacity 1.8" microSATA SSD (~512GB). However, the largest I can find nowadays are 256GB. mSATA SSDs seem to go larger, but I need it to be in a 1.8" microSATA form factor, which tops out at 5mm height. There is an abundance of mSATA to microSATA adapters out there, but everything I've seen is thicker than 5mm. So, are there any 1.8" microSATA SSDs out there that are larger than 256GB? Or, alternatively, are there mSATA to microSATA adapters out there that are 5mm thick or less together with the mSATA SSD? Thanks!
  7. Hi, Wondering if anyone knows of any single chip SSD controllers (doesn't require any DRAM), other than Sandforce and TDK GBDriver RS2?

    Fast drives on SATA-I controllers

    Thanks. Do you have the STR charts? Would like to take a look if possible.

  11. Hi, I'm wondering if there are any issues running fast drives on SATA-I controller(1.5Gbps). I didn't think it'd be a problem since even with 8/10 encoding, it should still deliver 150MB/s, which is faster than the sustained throughput of any single drive HDD out there(no RAID/SSD). However I've read that actual real world throughput is more like 90MB/s. I'm kinda skeptical of this claim since that would put its efficiency lower than even the very inefficient USB. So, what's the actual real world throughput of SATA-I?

    eSATA questions...

    Awesome! Thanks AmenophisIII

    eSATA questions...

    Can I find out what bridge chip it's using? I'm guessing the chip is there to bridge from USB->SATA rather than eSATA->SATA, since I don't believe any actual logic "bridging" is needed for eSATA and SATA, correct me if I'm wrong... So you're saying if the motherboard doesn't support eSATA in the BIOS, it won't be able to boot of it?

    eSATA questions...

    Hi, I'm wondering if it's possible to connect an eSATA enclosure directly to a motherboard's SATA connector and using it as a boot drive? The eSATA enclosure that I'm using has a bridge chip that converts from eSATA to SATA, and does some other logic on the data, so it's not your run off the mill eSATA enclosure that's simply a mechanical adapter. I want to be using it as a boot drive internally, so wondering if this was possible.
