CrucialT705 4TB PCIe Gen5 NVMe M.2 SSD - Up to 14,100 MB/s - Game Ready - Internal Solid State Drive (PC) - +1mo Adobe CC - CT4000T705SSD3

You might think (as I did) that you’re doing better by getting this OEM heatsink version – paying about $30 extra. I learned the lesson in a hard way that; exactly the opposite holds true. Crucial periodically runs deals; selling heatsink version even cheaper than naked drive. Don’t fall for that and simply buy the naked drive, whatever the price. Otherwise (if you buy heatsink version); you’ll either have to do below surgery (which is not for the faint-hearted) or your drive will fail earlier (because of heat) and Crucial will blame you running it that way (and very likely not honor your warranty – more on that later).This Gen.5 T705 is an extremely fast M2 drive. I’m very happy with its unbelievable performance. I use it on my new Asrock Taichi Lite Z890 motherboard. After I assembled my PC, I noticed that the hottest temperature on my system is this M2 drive. Not CPU, not GPU, not RAM modules and not my Gen.4 Samsung 990 Pro M2. While PC is completely idle (not running anything); that Crucial M2 displayed 61C temperature. I stress-tested my GPU (which is milimeters away from this Crucial) and that 61C quickly rose close to 80C (mind you; I’m not even stressing that drive itself). I immediately decided to replace that tiny OEM heatsink, as it’s completely not up to par for a decent cooling job.I’ll number my attached pics – so you can relate to my text here.I use HWiNFO64 freeware to check all my system characteristics. When you look at its reporting for this Crucial drive (pic-1); you’ll see that the drive keeps (in it) record of how long you used it at above 87C (warning) and 89C (critical). So if you (without even being aware) barbecue your drive and send it in for warranty replacement (when it fails); you can guess who Crucial will put the blame on?Now all new MBs put both that Gen.5 M2 slot and Gen.5 GPU slot right next to CPU (distance has to be short). You can see from (pic-2) that; this M2 drive is literally sandwitched between towering wall of GPU (no heat escape that direction) and my humongous Noctua NH-D15 G2 CPU cooler (airflow is there, towards rear suction fan). But it’s absolutely clear that; this OEM Crucial heatsink is just too small to provide adequate cooling. I even didn’t try Asrock MB’s original heatsink for that slot (as it’s even smaller). So it’s not even a matter of preference; you simply got to replace that OEM heatsink. That’s why it’s much easier to buy a naked drive to begin with; so you can avoid below pain of surgery.Another point; those Gen.5 M2 drives are just going thru initial growing pains (in fact, Crucial is still the only company to offer such speed-demon drive). Why is it putting out that much heat?; that is the first question (even more heat than Z890 chipset itself – which works fine with about same size heatsink). You’ll see on one of my attached pics (when I took out the naked drive); there is metal body Phison controller there (where actual two RAM chips have plastic body). Probably that much heat is coming from that Phison controller – not the RAM chips. If those Gen.5 M2 drives are all to put out so much heat; then industry will probably evolve to a different casing – so they can be cooled like CPUs. Time will tell.After searching many M2 heatsinks (active and passive); I decided on this passive Thermalright HR-09 2280 PRO (pic-3). There are ones with active fan cooling. But such small fans always fail in short time and they are noisy. So I went with this largest passive heatsink I could find. I hope that Noctua also starts making large M2 heatsinks. My Phanteks full-tower case can even house twice the height. Width-wise (as you are seeing in pic-3) it’s literally 1 milimeter from CPU cooler. Even if it touches there; no problem, as nothing moving (it might even get better cooling that way). When I run my PC with this new heatsink; Crucial M2 fall back to 47C. Still the hottest component on that motherboard; but much better than previous 61C with OEM heatsink on it. My other Gen.4 Samsung 990 Pro M2 runs at 42C anyway (under Asrock’s large metal surface heatsink). If I ever see my usage pushing it to above 80C; I’ll simply tweak my BIOS fan curve, to run my case fans faster / earlier. So far, 14C saving is good enough for me.Now on to surgery : how to remove naked Crucial drive from it’s OEM heatsink.I repeat: this process needs only two special tools (that you have to use), but more importantly very precise hand control (I happened to make my living as field service engineer – so it’s all easy for me). If you slip your hand once; you can instantly ruin your expensive drive. If you are not sure; don’t even try, I’d humbly suggest.You’ll need an anti-static mat (see wrist connection on pic-4) and blade opener tool (pic-5). No, you can not use a knife or flat-blade screwdriver instead. You were warned.On the side of the drive, you’ll notice two dimple dots on the edges and one flat line (blue arrows on pic-6). Insert your tool firmly but very slowly till you only pass that middle-line (if you push it all the way in; you’ll instantly damage the board/components of your drive; you can throw it away at that point). Once you merely pass that middle-line apply sideways leverage to rock it out of its grasp. Also do the same on both dimple dots. You’ll feel that the bottom casing cover slightly moved (pic-7). Now switch to other side with your tool and do the same there. As you slowly and patiently repeat that left & right few times; the bottom cover will start to come out (pic-8). Attention to the blue sticker indicated by arrow on that pic. As slowly pulling out that bottom metal cover; you’ll be peeling that sticker. No hasty movements there, as you don’t want to damage anything. Now that cover completely comes out (pics 9, 10).Now you remain with your naked drive sticking to actual heatsink, by blue-stickers on the other side (pic-11). This is the step needing utmost precision: you insert your tool between that blue-sticker and heatsink (and NOT between blue-sticker and the chip!). See detail on pic-12. You very slowly push your tool deeper towards other side (so; sideways, not length-wise). You are separating that blue-tape from the heatsink. Don’t you dare to yank the board by pulling length-wise; It’s a very thin board and you’ll simply snap it in two. Just be patient and do above described on those 3 blue-stickers from side to side.After enough loosening of stickers; finally lift your naked drive sideways (never pull length-wise). Pic-13.Now you have to clean all remnants of blue-stickers from both side of your naked drive. You’ll use your fingers and nails doing that (do not use any tool, as you can damage those microscopic components on board.Now your drive is finally ready to be mounted on to new heatsink (pic-14). Follow the simple instructions which come with heatsink. Just pay attention to orientation before you stick on to it; so you don’t put upside down. You’ll also need to align screw-hole of your drive and heatsink. After you place the bottom metal cover; you first firmly push it towards heatsink (firm, but not crushing hard) > then you tighten 4 side screws. So it gets good thermal conductivity thru new stickers on both sides.The hole of that new heatsink lines up with “screw-hole” of your drive. My Asrock motherboard has such “tool-less” rotating notch for that hole. So I was able to slide that notch between heatsink and M2 board. Pay attention how your motherboard mounting is (actually even before starting all this adventure). Because if you need to use an actual screw to mount your M2 drive to your MB; now you’ll need much longer version of this very tiny mounting screw. If your MB also has such “tool-less” thingy, I hope that it’ll also slide in as described above.If you are reading this before you actually bought your drive; I presume that at this point you decided to buy the naked version and avoid that Crucial heatsink nightmare at all cost, correct?!

This is my 6th set of gskill DDR5. In the beginning with the AM5 platform ram was a constant pain point. Back then EXPO was pretty much out of the question. It took months to manually overclock a stable system. After about 2 years of BIOS upgrades AMD, Asus, and MSI finally got it to a point where the average user could set expo and be stable. During this phase everyone was blasting the ram OEMs like it was their fault. I read countless reviews on listings like this one saying the ram was trash or that it couldn't have expo on. It wasn't gskills fault. This exact same ram runs flawlessly now in those exact same systems. I stick with gskill because I want m-die or a-die, their RGB looks the best, and I and can tune the hell out of it.

I have bought several of these, no failures They are fast and reliable so far. I consistently get 12GB/s on read with Crystal Disk Mark. As I expected, they require a heat sink to prevent throttling (and they throttle under heavy write loads even with a heat sink). I didn't try active cooling, but if I were going to use these in a mainly heavy load situation, I probably would.

Fast - I use two with RAID 0 and up to maybe 2600mbps Thunderbolt 3 speed. Has held up under pretty constant use and still performing without any problems.

Absolutely love this and will be returning back for a higher capacity m.2...Super fast transfer speeds marking a noticeable difference, with a beautiful sleek heatsink to keep all of your data protected from heat variances throughout your desktop case!It was so easy to install and great value for the money! She works really well and was compatible with my m.2 slot...

Since they were introduced in 2tb and 4tb sizes for computers, we have purchased 6 of these. Five were installed and ran without a problem. However, one didn't. So, I filled out the first form online with the serial number, etc., and attached a scan of the purchase invoice. After they confirmed that it was indeed a T705 and that we bought it, we got the next email two days later. With that, there was a further list of 14 questions and tests they wanted us to perform before sending the NVMe back, along with wanting screen captures of what appeared with each test. For some reason, they had a hard time understanding that the drive couldn't be put through the tests since the computer did not see the problem with the drive. I say computers because we tried to get it initialized on all 6 computers and 3 different software we have running in the shop - MAC, PC, and Laptop. Finally, I convinced them I knew what I was talking about, and they sent a label (NOT prepaid) to send the NVMe back.Where is the logic here? Why would we, or anyone for that matter, return a perfectly good drive only to be sent another of the same? This is especially frustrating when the product is under warranty. Ours was five weeks since purchase, so it couldn't be returned to Amazon, but that is what the manufacturer's warranty is for - I think that is correct. Who would buy any electronic item without a warranty to cover defective items?The bottom line is that we will be going back to the Gigabyte 12000 drives and hope Samsung will release their Gen 5 NVMe soon. We have purchased 57 NVMe drives so far this year; in the future, none will ever again be Crucial. We had to take the time to pack, pay for the shipping, and deliver THEIR defective product for replacement.UPDATE: We got a new drive three weeks after we returned the defective drive. Of course, in the meantime, we had to buy another drive. IMO, it is not fair to keep our client waiting because of Crucial's ridiculous policy. We did have a defective Samsung 990 earlier in the year, and it was returned with a pre-paid label, and we got a replacement within 10 days. — Let's see if Crucial pays any attention!2nd UPDATE: Well now the third one died. That is 3 out of 4 we bought are all dead. Finally I have learned my lesson.

This drive is fantastic. The load times for my games are noticeably faster than my older 2TB nvme. Worth the money!
