Crucial is unveiling the latest addition to its Gen5 consumer NVMe SSD lineup today - the T705 PCIe 5.0 M.2 2280 NVMe SSD. It takes over flagship duties from the Crucial T700 released last year. The company has been putting focus on the high-end consumer SSD segment in the last few quarters. The T700 was one of the first to offer more than 12 GBps read speeds, and the T705 being launched today is one of the first drives available for purchase in the 14+ GBps read speeds category.

The Crucial T705 utilizes the same platform as the T700 from last year - Phison's E26 controller with Micron's B58R 232L 3D TLC NAND. The key difference is the B58R NAND operating at 2400 MT/s in the new T705 (compared to the 2000 MT/s in the T700). Micron's 232L NAND process has now matured enough for the company to put out 2400 MT/s versions with enough margins. Similar to the T700, this drive is targeted towards gamers, content creators, and professional users as well as data-heavy AI use-cases.

The move to 2400 MT/s NAND has allowed Crucial to claim an increase in the performance of the drive in all four corners - up to 20% faster random writes, and 18% higher sequential reads. Additionally, Crucial also claims more bandwidth in a similar power window for the new drive.

The T705 is launching in three capacities - 1TB, 2TB, and 4TB. Both heatsink and non-heatsink versions are available. Crucial is also offering a white heatsink limited edition for the 2TB version. This caters to users with white-themed motherboards that are increasingly gaining market presence.

Phison has been pushing DirectStorage optimizations in its high-end controllers, and it is no surprise that the T705 advertises the use of Phison's 'I/O+ Technology' to appeal to gamers. Given its high-performance nature, it is no surprise that the E26 controller needs to be equipped with DRAM for managing the flash translation layer (FTL). Crucial is using Micron LPDDR4 DRAM (1GB / TB of flash) in the T705 for this purpose.

Crucial is confident that the supplied passive heatsink is enough to keep the T705 from heavy throttling under extended use. The firmware throttling kicks in at 81C and protective shutdown at 90C. Flash pricing is not quite as low as it was last year, and the 2400 MT/s flash allows Micron / Crucial to place a premium on the product. At the 4TB capacity point, the drive can be purchased for as low as 18¢/GB, but the traditional 1TB and 2TB ones go for 20 - 26 ¢/GB depending on the heatsink option.

There are a number of Gen5 consumer SSDs slated to appear in the market over the next few months using the same 2400 MT/s B58R 3D TLC NAND and Phison's E26 controller (Sabrent's Rocket 5 is one such drive). The Crucial / Micron vertical integration on the NAND front may offer some advantage for the T705 when it comes to the pricing aspect against such SSDs. That said, the Gen5 consumer SSD market is still in its infancy with only one mass market (Phison E26) controller in the picture. The rise in consumer demand for these high-performance SSDs may coincide with other vendors such as Innogrit (with their IG5666) and Silicon Motion (with their SM2508) gaining traction. Currently, Crucial / Micron (with their Phison partnership) is the only Tier-1 vendor with a high-performance consumer Gen5 SSD portfolio, and the T705 cements their leadership position in the category further.

    You are aware that Crucial (micron) sells the entire product stack right?
    If you want one in your laptop, get a T500 or P3 plus. Problem solved.

    I'm not "uncomfortable with a computer I can carry around," I'm a person who needs compute power and storage which are not the design goals of laptops.

    Kind of makes ya wonder how the PC gaming industry is so huge and growing. Where are they sticking all those rediculously expensive graphics cards I wonder? Must be some sector of fat giant laptops that I am just not aware of.
  • PeachNCream - Sunday, February 25, 2024 - link

    It isn't huge at all and don't mistake GPU profits for a representation of the number of parental dependent adults living in basements spending all their Uber money on video cards. A lot of graphics adapter sales are not in that market segment.
  • goatfajitas - Sunday, February 25, 2024 - link

    right, neither are all the Intel and AMD desktop CPU's LOL. You know how major corporations love to spend time and money on market segments that barely exists.

    I think what is happening here is you guys are mistaking a "shrinking" market with one that barely exists. Yes, desktops are shrinking of course, but by small percentage points... They are still around, still profitable and will be for a long, long time.
  • PeachNCream - Monday, February 26, 2024 - link

    There were numbers posted about the percentage of desktop CPUs sold on Anandtech recently demonstrating the comparable smallness of the desktop market, but hey, lash out and act threatened if you feel compelled to keep the man-child gamer stereotype alive by proving its not at a stereotype.
  • goatfajitas - Tuesday, February 27, 2024 - link

    Lash out? Where did I do that? I was just making light of your assertion that the PC market isnt worth anything. Specifically you say "there are not many desktop PCs still left in the world" - which I find funny. The other thing is you say its not a good idea to make a product that cant be used in a laptop. As if every major player doesnt have a variety of products that work in different thermal scenarios. SSD's are like CPU's and Video cards, they have lower power more efficient versions for mobile and faster stuff with desktops that can better dissipate the heat. But yeah, you know more than every production planning team at all these companies know, you are internet aware! LOL

    This is so confidently wrong using wild assumptions that I had to imagine it being said by a pretentious MacBook user.

    Have you used a modern laptop for gaming or anything besides browsing the web??

    Here's a simple explainer: "Developers have a laptop Problem"

    Physics has NOT magically changed, nor will it. Packaging is ALWAYS Size vs Thermals.

    The fact this needs to be explained to you makes me wonder why you commenting on a hardware review in the first place.
  • PeachNCream - Sunday, February 25, 2024 - link

    What's wrong with browsing the web? Didn't you do that to read this article? Are you suddenly a gatekeeper for a dying tech news site that sets the criteria for who can load a URL in their browser for a public website based on how you feel about your (incorrect) guesses about what they do with a computer? Get back under your bridge you silly troll and try again after reflecting on your own thoughts.

    Where are you living? 'Not many desktops left in the world...' That is too ridiculous to even laugh at.
