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.

    Go argue with the website you're reading for it's Feb 6 publication to that effect.

    Desktops is a shrinking market 🤷🏻‍♂️

    In the years to come, it will be relegated only to enthusiasts and professionals.

    Sign of the times …

    So, let me get this straight
    Are you saying that the T705 is not an enthusiast grade product?
    Or are you saying that it is, but you're disappointed that you can't somehow cram it into your consumer grade laptop?
    Because if it's the latter, there are a ton of fast Gen4 SSDs that don't run as hot.

    It's a growing market. Most datasets don't capture people buying desktop parts individually.
  • Samus - Thursday, February 22, 2024 - link

    The desktop market has its best year in nearly a decade in 2023, rebounding like 19%. There are two ways to look at this: windows 11 forced adoption of new hardware and businesses decided to cycle their infrastructure all at once (unlikely) or the "writing is in the wall" mentality that PC's are dying and everything is going mobile/cloud/tablet/etc turned out to be the joke it always was. Businesses will always demand productivity from their employees and contractors, and nothing is more productive than a full size keyboard, mouse, a few monitors and a powerful CPU. Add to that PC's continue to be the most economical adoption offering the lowest TCO when considering their 5+ year product life.

    While the gaming market drives the profits in the PC space, business drives the volume.

    All desktop, laptop and mobile become more useful and capable. Still when i sometimes look at videogames kids are currently playing on desktop i see that it's still very long way till the behavior of game characters reach human-like realism. So power and memory demands will continue to grow. NVIDIA day and night non stop cooking its bricks.

    Laptops are useless tech. Rarely a situation where a desktop isn't a better investment.
  • PeachNCream - Monday, February 26, 2024 - link

    There are, of course, situations where desktop computers still make sense, but the data do not support the assertion you've made in such a broad, unqualified manner. Sales of mobile parts are far higher and that is driven by their greater suitability as computing platforms than desktops by offering good performance at a reasonable price as shown here:

    Sure there are childlike pursuits and hobbies that people feel the compulsion to overspend on, but the business and personal consumer computing world has spoken and resoundingly so in favour of laptops and phones as primary computing devices with consoles acting as the electronic entertainment platform for the majority.

    How come SSD developers mumbling for 2 years that PCIe5 controllers overheat and continue cooking 12-14nm chips ? When you copy often data from the fastest PCIe4 SSDs you can not look at the process without cursing an swearing at these actual rates 1.5GB /s maximum, let alone 7.5 GB/s they all claim
  • goatfajitas - Sunday, February 25, 2024 - link

    im not sure where you get these #'s from, is your source and destination both equally fast?. I have 2 SSD's nowhere near the top of the heap and get double that. A Samsung 980 Pro 512gb that I bought in late 2020 and an Adata 2tb both PCIe 4 , the Adata slightly lower spec'd than the 980 Pro... I get a solid 3 GB/s when coping large files over 50gb from one to another and my stuff is 3 years old and PCIe 4.
