Crucial MX300 275GB 3D NAND SATA M.2 (2280) Internal SSD - CT275MX300SSD4

An M.2 SSD with fast read performance, and notably slower writes. The important specs are it's SATA (not NVMe), and it's 22x80mm (there's various lengths of M.2). You'll need a matching M.2 interface.I put two of these drives in a  StarTech.com PEX2M2 Adapter , on a PCIe 2.0 board (x16 slot but running at x4 or x1), which worked like a champ.Raw read speed (sequential) per drive was about 460MB/s in this configuration (well below SATA3's theoretical max, but much faster than SATA2 could deliver). Both drives reading at once capped each drive at ~370MB/s. I'm not sure if I was maxing out the card or the PCIe configuration, but the numbers should be better under PCIe 3.x-- Crucial claims a ceiling upwards of 500MB/s.Write speeds were harder to calculate; the drive uses a caching mechanism which greatly speeds up short writes, but the cache fills up in 15-20 seconds, so extended writes then fall back to speeds comparable to older SATA2 drives until the cache flushes out. This design will work very well for bursty writes (think web browser on-disk history) but will feel slow for moving large data. I got ~250MB/s on sequential write while the SSD's cache was working, and 150MB/s when the cache filled up.Note these were raw reads / writes. A filesystem, RAID, or other intermediate layers will add some overhead (in my tests FreeBSD GEOM mirror costs about 4-5% in performance). OS caching will also throw off results, writing through the GEOM mirror was far more variable than my raw writes.On FreeBSD 10.3, this SSD shows up thusly in dmesg:ada0: <Crucial CT275MX300SSD4 M0CR031> ACS-3 ATA SATA 3.x deviceada0: 600.000MB/s transfers (SATA 3.x, UDMA6, PIO 8192bytes)M.2 aka NGFF are superior to traditional drives for several reasons:* simpler design: no separate power or SATA data cables (and no needing to be sure your data cables are in spec for SATA3)* lower heat dissipation / power draw than 2.5" SSD.* the small size fits in diminutive or non-traditional cases. No casing, brackets, or cables makes for better airflow in large cases.* attaches to PCIe bus, bypassing potential SATA controller bottlenecks. Models like this one still speak SATA so the protocol is still a limit.Possible negatives:* Poor heat dissipation (no heatsink, no metal case to draw off heat)* Still bound by SATA3 performance bottlenecks and overhead* A couple of these can max out PCIe 2.0 lanes, needs PCIe 3.x for max performanceWith most SSD, as you move to larger capacity (more chips), the price is a little better per GB, and performance should also improve. But the next real performance enhancement moving up from this M.2 would be an NVMe interface.The MX300 offers good performance at a price barely higher than traditional 2.5" SSD, from a trusted US-based brand (Crucial has long been my go-to for DRAM). Recommended for space-saving performance.

After many many hours spent over two months trying to make the Oculus Rift CV1 work consistently, I've found the best possible combination and I think this info will really help those looking for a hassle free experience. My experience will be especially relevant to folks who need their other USB ports to work for things like Joysticks and any pilots looking to use Flyinside.In short the two absoulute must haves for a good VR experience are:1) The MSI Z270A Xpower Titanium Motherboard because it has a supplemental VR Boost power 6 pin connector on the board that ensures no drops or judders even when I'm using three sensors, the Xbox one controller, wireless USB Keybord/Mouse. The overclocking function within BIOS OR with the included physical switch is a one click wonder with OC levels from 1-11. I set mine to a maximum setting of 11 and the I5-7600K bumped up from 3.8 to 4.9 GHZ with temps at 40 deg Celcius idle/60 deg playing any Oculus games/80 deg for CPU intensive FSX at Max settings with Flyinside.2) A Sata III or M.2 SSD because Windows 10 just doesn't work well with a mechanical HDD as these always show at 99-100% disk usage even after fresh windows installs with nothing else on the HDD!Here is my perfect VR Rig for the OculusMB: MSI Z270A Xpower Titanium Motherboard (Amazon Warehouse deals $290)CPU: Kaby Lake I5 7600K one click OC to 4.9 GHz (Amazon new $240)GPU: ASUS GTX 1080 Rog Strix BC 1835 MHz (Amazon Warehouse deals $485)RAM: Corsair Vengeance DDR 4 LPX 8 GB 3000 MHz (Amazon new $70)HD: Crucial MX300 1TB M.2 (2280) SSD (Amazon new $270)PS: EVGA G3 850W (Amazon new $120)CASE: Corsair Graphite 780T (Amazon Warehouse Deals $150)USB: On Board Intel eXtensible ports ($0)DEVICES: Logitech USB Wireless Keyboard & Mouse / Saitek CyborgX / 3 Oculus Sensors on USB 3.0 / Oculus RIft on USB 3.0OS: Windows 10 Education (Free for anyone with a college email address)PROGRAMS: Oculus Home, EA Origin, Steam, VorpX, FlyinsideIf I want I can even have a gazillion programs and overlays running without problems in the background, such as all the Motherboard utlities, GPU utilities, CPU-Z, EA Origin & Steam and still play Oculus/Unspoken/EVE Valkerie at Ultra settings. Spec'ing a similar ALienware Aurora config with slower RAM/slower GTX 1080 was ~ $300 more at $1900 while mine cost $1600 after I convinced my wife to let me go all out in the end :)Here are the combinations that DID NOT work without USB disconnects (eg. mouse/keyboard/Xbox controller stops working when running Oculus). This is after I followed the Oculus team's advice on USB cards and their Windows 10 USB power management disabling guide.1) Dear wife, I only have to get a graphics and Inateck card because my 7 yr old OC I7-920 is still powerful. Promise to spend less than $1000 with Oculus Rift and Touch included!MB: Asus P6X58e-WS / CPU: Core I7-920 OC 3.8 GHz / GPU: ASUS GTX 1060 6 GB / RAM: OCZ 8 GB DDR 3 1600 MHz / HD: Hitachi 1 TB 5400 RPM / PS: OCZ 700W / USB: Inateck 4 port CardDidn't work due to constant USB disconnects.2) Dear wife, I only have to get this additional $100 USB card that Oculus is recommending and I need to spend an extra $100 on a GTX 1070.MB: Asus P6X58e-WS / CPU: Core I7-920 OC 3.8 GHz / GPU: EVGA GTX 1070 8 GB / RAM: OCZ 8 GB DDR 3 1600 MHz / HD: Hitachi 1 TB 5400 RPM / PS: OCZ 700W / USB: Highpoint 4 Port USB 3.0 RocketU 1144DDidn't work due to BSOD's "System Thread Exception Not Handled" and then "Clock Watchdog Timeout".3) Dear wife, I only have to go back to the Inateck card again and use USB 2.0 for one of the two sensors and the headset.MB: Asus P6X58e-WS / CPU: Core I7-920 OC 3.8 GHz / GPU: EVGA GTX 1070 8 GB / RAM: OCZ 8 GB DDR 3 1600 MHz / HD: Hitachi 1 TB 5400 RPM / PS: OCZ 700W / USB: Inateck 4 port CardDidn't work due to USB disconnects.4) Dear wife, this wont cost us anything. Can you tell me where you put my old MSI X58 pro MB? Dear God, please help me:)MB: MSI X58-Pro / CPU: Core I7-920 Stock 2.66 GHz / GPU: EVGA GTX 1070 8 GB / RAM: OCZ 8 GB DDR 3 1600 MHz / HD: Hitachi 1 TB 5400 RPM / PS: OCZ 700W / USB: Inateck 4 port CardIT WORKS!!! Was working great with one sensor/headset on USB 3.0 card one on USB 2.0. No USB disconnects at all.5) Dear God, I must have room scale and really need a 3rd sensor. Dear wife, only one more $20 Inateck card and $60 Oculus sensor plus I asked God almighty upstairs and I'm sure he'll come through like last time? I even gave $20 in charity!MB: MSI X58-Pro / CPU: Core I7-920 Stock 2.66 GHz / GPU: EVGA GTX 1070 8 GB / RAM: OCZ 8 GB DDR 3 1600 MHz / HD: Hitachi 1 TB 5400 RPM / PS: OCZ 700W / USB: 2 Inateck 4 port CardsCrap! The power went off after a split second. Lets try with only one card. Nope, system wont post.6) Dear wife, I only have to spend $60 more to get a new relatively inexpensive XEON CPUMB: MSI X58-Pro / CPU: Xeon x5687 3.6 GHz stock / GPU: EVGA GTX 1070 8 GB / RAM: OCZ 8 GB DDR 3 1600 MHz / HD: Hitachi 1 TB 5400 RPM / PS: OCZ 700W / USB: Inateck 4 port CardDidn't work due to system still wouldn't post7) Dear wife, I'm sure the ASUS will work with only a new power supply. I need $120.MB: Asus P6X58e-WS / CPU: Xeon x5687 3.6 GHz stock / GPU: EVGA GTX 1070 8 GB / RAM: OCZ 8 GB DDR 3 1600 MHz / HD: Hitachi 1 TB 5400 RPM / PS: EVGA G3 850W / USB: Inateck 4 port CardDidn't work, system wouldn't recognize either Inateck card.8) Dear God, I know you love me more than my mother does and I want a great computer so I can play VR and FSX with Flyinside since my dream of flying real planes is dead; I hear you have infinite treasures and I beg you help me out pleeeease Lord. Dear Wife, I can totally explain today's orders from Amazon... Lets eat out tonight :0MB: Asus Z270e Rog Strix (Amazon Warehouse Deals $200)/ CPU: Kaby Lake I5 7600K Stock 3.8 GHz / GPU: ASUS GTX 1080 Rog Strix BC 1835 MHz / RAM: Corsair Vengeance DDR 4 LPX 8 GB 3000 MHz / HD: Hitachi 1 TB 5400 RPM / PS: EVGA G3 850WDidn't work! Just like the old Asus X-58, constant USB drops. Hard disk always at 99%. Crap, is the Oculus returnable?9) Dear Amazon, either Asus lied when they said VR Ready or I think you sent me a bad board so I will buy a cheaper ASUS from you.MB: Asus Z270A Prime (Amazon Warehouse Deals $160)/ CPU: Kaby Lake I5 7600K Stock 3.8 GHz / GPU: ASUS GTX 1080 Rog Strix BC 1835 MHz / RAM: Corsair Vengeance DDR 4 LPX 8 GB 3000 MHz / HD: Hitachi 1 TB 5400 RPM / PS: EVGA G3 850WDidn't work. Windows 10 would not install and I figured its time to call it quits on ASUS since the Z270e was better than this Z270A.10) Dear wife, whats another $100 for the sake of my happiness? Its not like we can afford a vacation during your college spring break anymore anyways. $500 left in the bank will hold us to next payday I'm sure :)MB: MSI Z270A Xpower Titanium Motherboard/ CPU: Kaby Lake I5 7600K OC 4.9 GHz / GPU: ASUS GTX 1080 Rog Strix BC 1835 MHz / RAM: Corsair Vengeance DDR 4 LPX 8 GB 3000 MHz / HD: Crucial MX300 1TB M.2 (2280) SSD / PS: EVGA G3 850WIt works flawlessly! Dear God, thank you! You've rewarded my faith, prayers and patience with the ultimate in gaming happiness. Dear Wife, you've got to try this! WIFE: "Oh wow this is so realistic"!Hopefully my rant above will save some of you folks some time, headaches, frustration and ultimately some money. The Oculus Rift CV1 is AMAZING but don't expect the in store demo experience if you cheap out on either the Motherboard or the SSD. The MSI Titanium Z270a Xpower and any SSD for at least the OS are a MUST HAVE. Everything else you can compromise on and build a system at 1/3rd to 1/2 the cost of mine. To be honest because of ASW the GTX 1060 6 GB was really good even with Dubug Tool Pixels set to 1.5 but I decided to futureproof. My original 17-920 system was built for FSX but the boxed edition caused way too many DLL errors. 7 years later, combined with the Steam edition of FSX ($5 for code on Amazon) I basically have 20 different airplanes in my house and a flight experience almost identical to the real thing (Thank you Flyinside)

Muito poderoso. Estou muito satisfeito com o produto! O produto eu recomendo. Único problema foi com a entrega que ultrapassou o tempo limite, quanto ao produto, excelente!

Crucial delivers again with another great SSD product! My latest purchase from them is in the M.2 flavour and it makes the perfect storage drive for my OS and system files. Not to mention Crucial makes a quality product and this will be my 4th SSD I have purchased from Crucial. Two of which are M.2 drives. I have not had a single issue with any of them and I love the price they come at.This 275GB M.2 is currently the best priced $/GB M.2 available between the 100-300GB range and is a fantastic choice as a OS/boot and system files drive. I am using this for exactly that in my latest ITX build that I use for work and can’t think of one thing to complain about with this M.2. Also, the 275GB of storage is more than enough for all the basics you would need, if you have a hard drive for all you mass storage then you will never need more storage than this for a boot drive.Spec wise it’s also good too and has better reads and writes over even more expensive options.Sequential Reads up to 530MB/s, Writes up to 510MB/s, MTBF* of 1,500,000 million hours, Price at time of purchase on Amazon $125.71MTBF* Mean Time Between Failure, is the predicted elapsed time between inherent failures of the hardware during operation.The install of an m.2 is as easy as it gets, there’s no sata cables needed like regular SSD’s, you just need to make sure your motherboard has an m.2 slot for the size of m.2 stick you buy. This particular stick is the most common size M.2-2280. You slide it into the slot and fasten it down with a screw that your motherboard manufacturer provides, and that’s all there is to it!So Crucial’s product performs exactly as expected and I have incredibly quick boot times. I am very happy with this purchase and recommend this product to anyone interested!

He comprado la versión M.2 con capacidad de 1 TB para un portátil Alienware 13 R3 como segunda unidad de almacenamiento. El paquete incluye: la tarjeta SSD tipo M.2, dos tornillos para sujeción (en mi caso no fueron necesarios debido a que mi portátil incluía el tornillo en la segunda ranura libre de expansión) y una hoja con instrucciones para descargar y registrar el programa de clonado de discos Acronis True Image HD. En mi caso la instalación fue muy sencilla. Importante: acordaros de retirar la batería de vuestro portátil antes de instalar la tarjeta SSD. Una vez instalado Windows 10 lo detecta en el primer inicio pero hay que formatearlo con el programa “administrador de discos” de Windows para que podamos utilizarlo, asignarle una letra de disco o ponerle una etiqueta (nombre), esto último es opcional. Una vez formateado, el disco presenta un tamaño útil de almacenamiento de 975 gb aproximadamente. La experiencia de uso es muy satisfactoria, siendo un disco muy rápido con mucha capacidad de almacenamiento con el mejor precio de compra.

I was in dilemma-- what to opt; this one or Samsung 850EVO. Samsung is a slightly better performer having a longer warranty for 5 years, while Crucial offers larger storage capacity at a slightly lower price. Since, my purpose is to use it as an external storage I opted Crucial (available storage 488 gb vs 465 gb of Samsung). I do have a Samsung and I compared them and the difference is hardly detectable. After all crucial is a good ssd, but the price appears to be a bit higher than I expected. Amazon should think about its price (particularly considering the fact that Samsung is a popular brand in India) so that more and more people can opt it,

Wie immer ein dickes Dankeschön an Amazon für die rasante Lieferung.Crucial MX300 SSD 525GB M.2 2280SSBestellt habe ich mir diese SSD um die interne SSD meines ASUS Zenbook Prime UX31A aufzurüsten. Die dort verbaute Sandisk SSD war mit 120GB letztendlich zu klein bemessen und auch zu langsam. Um die SSD allerdings zu tauschen musste ich etwas basteln, da die von ASUS verbaute SSD sehr fest verschraubt war. Des Weiteren musste ich mir über eBay einen kleinen 18 auf 16 Pin Adapter bestellen, da ASUS nur zwei spezielle SSD’s in seinen Zenbooks verbaut. Mit dem Adapter war der Einbau kinderleicht und ging schnell von der Hand. Auf den Bildern sind die ASUS SSD und die Crucial mit Adapter im Vergleich.Mit Hilfe des AS SSD Benchmark Programms habe ich die Transferraten der beiden SSD’s verglichen und das Ergebnis fällt mehr als eindeutig aus. Die Crucial ist um Längen schneller. Die Schreibraten sind um ein Vielfaches schneller und besser und auch die Zugriffszeiten sind der Wahnsinn. Auf den Bildern habe ich ebenfalls beide SSD’s verglichen. Natürlich bremst der interne Controller in dem ASUS Zenbook die SSD aus. Theoretisch wär noch mehr Speed drin.Da ich mein Zenbook primär für Photoshop und Lightroom etc. verwende, merke ich den Geschwindigkeits-Boost deutlich. Lediglich meine 4GB RAM sind ein Flaschenhals und leider nicht erweiterbar.FAZITIch bin mit dieser SSD mehr als zufrieden. Einen halben TB mit solch guten Geschwindigkeiten in einem Notebook ist sehr angenehm. Und das alles für einen fairen Preis (ca. 145€ beim Kauf). Von mir eine klare Kaufempfehlung.PS: Der Adapter hat mich bei eBay knapp 10€ gekostet, also absolut in Ordnung.
