    Make sure you bring your own screw!

    Would be nice if you provided your customers with the M.2 screw to hold it in place rather than making them go about finding one. I know you've provided them in past SSD's. I'd imagine it would probably cost you a whole penny wholesale. Instead, after I spend hundreds on this product and purchase 2 day shipping I was forced to wait until the next day to drive an hour round trip to the hardware store to buy 2 for 47 cents. Thanks!

    DO NOT BUY PRODUCT UNDER ANY CIRCUMSTANCE

    I purchased this product for my Lenovo E580 and installed it with relative ease, however Crucial has rolled out a software known as Executive Storage. During the setup process they heavily imply that you need to download this software to help maintain your SSD and have it function at its full capacity. This software destroys your SSD and erases data from both your NVME SSD and current drive. I called tech support and was on the line for over 2 hours and they stated that they knew about the defect with executive storage yet Crucial has done nothing to fix it.I was on the line for 2 hours as they suggested the same solution over and over and after all that effort, they merely said that you can return it and we might be able to get a new one back to you in approximately 4-6 weeks. Absolutely horrendous product with even worse software to go along with it. Seriously, pick any other SSD, the Samsung Scorpion 970 EVO series is a far better option.

    Absolutely fantastic speeds!

    Although I have been running SSD only computers for a while, they have always been the standard SATA SSDs, limited to about 550MB/sec transfer rate, which is already very fast when compared to even the fastest SATA HDs. However after researching and watching many review videos, I decided to give the Crucial P5 a shot, and I am extremely glad I did! As you can see in the two uploaded screenshots I have provided, my SATA SSD, (a Crucial MX500 1TB) reads at about 562 MB/sec and writes at about 517 MB/sec. However when running that same test on the Crucial P5 NVME SSD, the read speeds are around 3500 MB/sec and write speed is around 3200 MB/sec! The speed increase is off the charts! I am very happy with my purchase!

    Great upgrade for a Dell G3 3779

    I upgraded my Dell G3 3779 laptop by replacing the original C: drive, a SK hynix 128 GB SSD, with this Crucial P5 1TB. Higher performance and much greater capacity. I used a USB 3.1 NVMe PCIe enclosure (amazon # B07MNFH1PX) to clone the SSD to the P5. I used the clone function from a free copy of Macrium Reflect rather than the Crucial version of Acronis True Image because Acronis requires installation of the new SSD before doing a clone & Macrium allowed me to do the clone prior to opening the laptop. Macrium also allowed for an easy resize of the main ssd partition to allow full use of the larger space. The install was pretty painless and the machine booted from the new drive immediately following the install. No problems & very happy with the result. I had verified compatibility via the Crucial configuration tool on their web site before ordering via Amazon. Crystal disk mark verified the drive met it's published specs.

    Excellent

    Works as expected. Write speeds are as advertised. Trades blows with 970 evo, but falls behind at smaller reads/writes. Peek write speeds beat 970 evo hands down. See Crystal disk mark for details. Fresh install of windows

    If you’ve never replaced your SSD, study up first

    Installation goes easily if you are prepared. Do your homework, look for the best videos (lots of junk out there). Recognize what even the best videos gloss over and research those vague areas. Have a safe place to put all screws, neat workspace, good lighting. Get a caddy for copying over your old drive to the new one, so when you replace the old one you can use it in the caddy as an external SSD. Study how the copying process must be adapted to partitioning the old drive to its full available size.I love having a huge C drive, ended all my anxieties about the steady decrease in available space. Several computations now go much faster when they use the C drive for application data. Worth the investment and cheaper than buying a new laptop.

    You Do Not Know What You Are Missing UNTIL You Add This To Your Computer

    The Crucial P5 500GB HD (3400/3000MB/s) did what was asked and more. It definitely made our office HP 15-cs3073cl laptops all around better performing. It is a really decent laptop, but the hard drives (1TB 5400rpms are garbage). It was an easy way (cost efficient as well) to upgrade a our laptops (that supports NVME M.2 with a M Key - the little slit on its end. There are B keys, M Keys and B/M Keys on different M.2s) so you are way ahead of most admin/staff laptops in school districts. Now, I have this super fast Crucial HD as my main hard drive and the old 1Tb 5400rpm HD as by back up. This is great because I have speed and still space to store pictures and videos, etc.. So, if you have a laptop and it can use a MVME M.2 HD w/ a M-Key, do not hesitate to purchase this one. A+ Product. UserBenchmarks: Crucial's P5 500gb M.2 got a score = 258% (exceptional.) My WD Black SN750 NVMe PCIe M.2 1TB got a 283% (exceptional.) My Samsung 860 Evo 500GB got a 118% (Outstanding). My WD Blue 1TB (2012 - 102% Outstanding. The original HP15 WD WD10SPZX-00HKTT0 (5400rpm) got a 61.7% (Good...BUT IT IS SO SLOW next to a SSD or M.2.) If this was a grading scale...a 61.7% is not good it is barely passing in education. Plus, it is really easy to see the difference. Startups, downloads, and updates take FOREVER on the the 5400rpm HD. If you have never updated your drive...then you do not know what you are missing. Just saying....Side note: This is the easiest area to cut costs when purchasing a laptop/computer and EASIEST way to update it on a budget and still save money in laptops and computers. Ram is another area. Crucial makes both.Latops - you typically can't upgrade much other than the HD and RAM. Most higher end laptops have some wiggle room, but not in all cases. When you buy it...if they give you "upgrade options"...then you know where you can add or subtract down the road. Keep in mind that in some cases they even solder the RAM to the board - which makes it difficult to do much there.To Clone: Crucial makes it easy. All you have to do is... (You must have a M.2 connection and a SATA connection. At least one of each to do the following. Otherwise, you will need to search online on how to clone your hard drive with what your present setup looks like.) Most laptops and computers have at least 2 connections. One may be M.2. If it is not, then do not but this hard drive. You can use my directions below, but not with this hard drive.1.Download the Software and Install it: Acronis True Image for Crucial (other brands have the same thing also) - do a search Crucial Clone Software.2. Install the new hard drive. DO NOT REMOVE your old hard drive at this time. Please leave your old one in as your MAIN still. Let it boot up.3. Find your NEW HD. It can be found by running DISK MANAGEMENT on your computer and formatting your new drive to add it to your computer. (It should be found under "THIS PC" shortcut on Win10.4. Make sure your new hard drive is the same size or larger than your old one. (Remove some programs that are easily reinstalled - like video games if you need a little space.) You want to CLONE everything over to the new one. I went from 500gb to 500gb...the amount moving over was smaller than the new empty hard drive. I deleted a couple of video games too - off the record of course. :)5. Start Acronis software and Clone (under tools) your old one onto the new one. If the old one is a 5400rpm HD...go eat lunch or dinner. You will have some time. Our 500gb - 5400rpm HDs took about 30-45mins. A 500bg 2.5 SSD - 10 minutes max from start to finish.6. Once it is cloned, turn off your computer and either disconnect the SATA connection or take out your old hard drive. Start up your computer and it will find the new hard drive. If the process results in a corrupt set of files on boot, I did not mess with it. I reinstalled my old one and booted from it and formatted the new drive and started over. (I was not wasting time "fixing" a fresh CLONE. Who was to say other errors might not show up later?) I wanted to be safe versus sorry. Shortcuts get me in trouble sometimes.7. Once you are ready to boot form the new drive, disconnect the old one again. If it boots, then it should be your main one now for booting.8. You can shut it down and reconnect or install the old one and it should be your backup drive now. Go to "THIS PC" and see which one is your "C" and which is your "D". If it is not correct, you should have noticed the load up time in the beginning was ridiculous if using the 5400rpm and/or it is labeled as "C". How do know which is which? Well, once I clone my original drive, I delete something off of it to make it smaller. Secondly, I look at the total sizes. Typically those are not identical. In my case, one is 464gb and the other is 931gb. Pretty easy for me to tell them apart.)9. If everything worked out and the M.2 is now your main drive, then you are good to go! Enjoy.10. If it did not work, then you will need to shut your computer down and go into your bios. If you do not know how to get into it...look it up. Some are f2, others are f8 or F12 and mine was F10.11. Hold the specific F-key down when you restart it and enter the bios. You will need to change the HD boot order. It needs to be your M.2 first and then the other drive. Save your progress and restart.12. Check how fast it starts up. Then check "This PC" if it is correct, then all is well.13. If it is not...then you probably did not save your work when you entered the bios. Try that again.14. Most of this can be found on the internet as well. Best of luck.THANK YOU, CRUCIAL for making my upgrade EASY.

    Ziemlich gut aber nur mit zusätzlicher Kühlung

    Nachdem sie jetzt endlich auf dem Markt ist, habe ich mir die Crucial P5 in der 500 GB Version gekauft. Zum direkten Vergleich besitze ich auch eine Samsung 970 EVO Plus mit 500 GB im gleichen PC.Unter Windows 10 liegen beide SSDs im CrystalDiskMark in Summe fast auf Augenhöhe (mit dem Samsung NVMe-Treiber v3.3), siehe Bilder.Im AS-SSD Benchmark liegen die Werte der P5 sogar etwas höher als bei der EVO Plus:Crucial P5 read = 2530, write = 2520EVO Plus read = 2510, write = 2330Wer die P5 unter Windows 7 betreiben will, benötigt zwingend den aktuellen x64_Legacy NVMe-Treiber von 'Micron' (Crucial=Micron), da die P5 mit dem Microsoft NVMe Treiber KB2990941 extrem schlecht performt (bestenfalls nur noch halbe Geschwindigkeit!). Außerdem stürzt der Microsoft Treiber auf vielen W7-Systemen mit einen 007E BSOD ab, wofür man dann auch noch den Hotfix KB3087873 benötigt.Um den aktuellen 'Micron'-Treiber v2.1.15.56 (enthält W10 und W7 Treiber) zu erhalten, muss man bei Micron einen Customer-Account anlegen. Bei 'Crucial' selbst findet man keine NVMe Treiber, außer der Crucial-Storage-Executive SSD-Software, die zwar fehlende Treiber anmahnt, aber selbst nicht downloaden und installieren kann.Wenn im Betrieb der Cache der P5 voll ist bricht die Schreibgeschwindigkeit kurz ein und stabilisiert sich dann aber bei rund 2000 MB/s Steady State (siehe Bild), sofern sie noch 'reichlich' leere Zellen hat. Allerdings geht es mit der Schreibrate steil bergab wenn sie zu heiß wird. Die P5 wird ebenso wie die 970 EVO Plus sehr schnell sehr heiß! Aber immerhin erreicht sie eine Steady State Geschwindigkeit von sehr guten 2000 MB/s und deswegen habe ich sie mir gekauft, denn ich benötige sie zum Cachen in einem 10 GBit/s Netzwerk. Die EVO Plus kann ich dafür nicht brauchen, denn die bricht schnell auf eine Steady State Phase von 800 MB/s ein.Im Standby bei offenem PC-Aufbau (Raumtemperatur 20°C, keine Kühl- oder Wärmequellen in der Nähe) erreicht die Crucial P5 bei mir nach kurzer Zeit rund 47°C, nahezu identisch mit der EVO Plus. Bereits wenige größere Schreibvorgänge oder Benchmark-Tests lassen die Temperatur rapide ansteigen und bei finalen 75°C bremst die Crucial dann auf SATA-III Geschwindigkeit herunter. Die 500 GB 970 EVO Plus kann unter allen Konditionen inclusive Thermal Throttling immer noch knapp 750 MB/s halten, die Crucial P5 fällt da aber deutlich unter 500 MB/s ab. Bei guter Kühlung mittels Cryorig Frostbit oder Sabrent Rocket Cooler gibt es aber bei beiden überhaupt keine thermische Drosselung.Mein Fazit: die 500 GB Crucial P5 performt in manchen Punkten sogar besser als die 500 GB 970 EVO Plus und ist aktuell rund 15% billiger. Aber ohne vernünftige zusätzliche Kühlung wird sie ebenso wie die EVO Plus ziemlich schnell zur Spaßbremse.

    Faster than the Flash versus Superman in the 100m sprint!!!!

    How can something SO SMALL be so dang quick??? Windows is booted up before I can blink, and no waiting around for start-up programs to load, nope, not with this bad boy! Once you hit the Desktop (8-10 seconds flat) you can be playing a game 4 seconds later.I never knew playing my games on an old Western Digital HDD was wasting so much of my life waiting for windows to boot, and sitting at loading screens with a disgruntled sigh, whilst picking my nose.... waiting, and waiting.This tiny magical stick has changed my life. It's the shape of a ram stick, but around 4 times smaller, and about 2-3mm thick.Benchmarking it shocked me. over 3000mb/s. I thought my 2.5" SATA SSD was speedy at 400mb/s. As long as you have a relatively new Motherboard which has a Gen 3 M.2 SSD port you are going to thank me for reccomending such a piece of hardware. This is INSANE!It seems like every time they make something smaller it gets faster/better by an order of magnitudeI only got the 500GB one, my trusty Kingston 240gb SATA SSD, and a 7200rpm 2TB BarraCuda with a 256 cache SATA HDD.I think nearly 3TB of storage space should be enough for now, yet one can never be sure with some games taking up over 100GB of disk space now. Maybe I'll grab another of these (a 1TB one....just to be sure).Honestly, I think our governments are in contact with aliens and jacking their technology. I remember buying a Crucial MX100 256GB around 6-7 years back, and being in awe of the speeds......read speed of 415, write speed of 319, and a mixed speed of 288, Now we have something 90% smaller, well under a decade later my read speed is 2673, write speed is 2350, and mixed speed of 1524! 10 times smaller and 6 times faster.We need to get into Area 51 and steal that alien technology, QUICK!!!! LOL

    PROBLEMA CON ACRONIS....RISOLTO...ECCO COME.

    Avete già un nvme ed un solo slot? Avete seguito il consiglio del tutorial di procurarvi un lettore usb-nvme? Acronis non parte perchè dice che non avete un ssd Crucial? Bene ....leggi il mio consiglio perchè è stato veloce ed indolore. Premessa....acronis è moooolto lento a reagire ai comandi in questo caso ma funziona bene. - Preparate la penna usb con windows 10 da installare. - Scaricate Acronis per Crucial dal sito e mettetelo in una penna usb, anche la stessa di installazione di win10. - Installate tranquillamente il vostro nuovo nvme sulla scheda madre. - Il vostro vecchio ssd nvme inseritelo nell'unità esterna usb. - A questo punto avviate una nuova installazione di windows 10 nel pc, tanto ci vogliono 10 min. - Collegate il vostro vecchio ssd inserito nell'unità esterna usb e attendete che il sistema lo riconosca. - Non perdete tempo ad installare driver o quant'altro, dalla penna usb installate Acronis. - Il vostro nvme viene riconosciuto da Acronis come Crucial e quindi si avvia. - Ora è il momento di clonare il vs vecchio nvme su quello nuovo ed il gioco è fatto, lasciate pure tutto in automatico che è perfetto. - Acronis vi chiede solo un riavvio, al termine del riavvio inizia la clonazione. Una volta finita il pc si spegne ed è già pronto a ripartire con il nuovo ssd nvme.Speri di esservi stato utile.

    SSD NVMe estremamente veloce

    L'ho acquistato per installarlo dentro il mio laptop MSI GE75 Raider 9SE. E' arrivato con tutta la memoria non allocata, come avviene per la maggior parte delle memorie secondarie appena acquistate, ma con una rapida formattazione dal tool Gestione Disco di Windows diventa subito operativo.Per quanto riguarda le velocità di lettura e scrittura, esse si aggirano su quelle nominali specificate da Crucial. Avendo io un laptop con batteria tampone, ho potuto subito attivare la Momentum Cache dal software Crucial Storage Executive, che ha permesso di ottenere un incremento delle velocità, in alcuni casi anche a più del doppio di quelle specificate. Questo è possibile perchè Windows può essere istruito per usare una parte della memoria RAM del computer come cache per mantenere una parte dei file che sono scritti o letti dal SSD. Nelle immagini con CrystalDiskMark si vede perfettamente la differenza tra Momentum cache attiva e non attiva. In effetti, le misure eseguite con Momentum Cache attiva sono date per lo più dalla velocità della RAM del laptop, piuttosto che del SSD, per cui perdono rilevanza nella valutazione del SSD.Per quanto riguarda le temperature, c'è da dire che la casa produttrice specifica un esercizio tra un minimo di 0° Celsius e un massimo di 70° Celsius, ma accedendo con HWINFO alle proprietà del P5, si notano subito una temperatura di Warning pari a 78° Celsius (quella a cui avviene il Thermal Throttling con conseguente riduzione temporanea delle performance al fine di raffreddare l'unità) e una temperatura Critica pari a 81° Celsius (quella che l'SSD potrebbe raggiungere nel caso in cui qualcosa, come il Thermal Throttling, non funzioni a dovere). La temperatura media si aggira comunque tra i 52 e i 57 gradi a regime, rimanendo comunque nell'intervallo di esercizio. Trasferendo grossi file, soprattuto in scrittura, la temperatura sale tranquillamente oltre i 60° Celsius, come è normale per un SSD NVMe. In rari casi può raggiungere temperature oltre i 70° Celsius. In particolare, io ho provato a spingerlo il più possibile con un grosso trasferimento sequenziale (64 Gigabyte con CrystalDiskMark), e dopo circa un minuto, ha raggiunto anche i 75° Celsius, come si può vedere dall'immagine con CrystalDiskInfo. Il Thermal Throttling funziona perfettamente, perchè i 77° Celsius non sono mai stati superati, come si nota dall'immagine su HWINFO (Time Above Warning Temperature Threshold), neppure durante il grosso trasferimento che ho dovuto eseguire per copiare i miei file dal vecchio SSD SATA (durato circa 20 minuti su 400 Gigabyte), e ogni volta che i 77° Celsius venivano raggiunti, diminuivano le performance per brevi istanti e la temperatura scendeva subito sui 72/73° Celsius. Questi valori di temperatura sono perfettamente normali, perchè rientrano nelle specifiche interne dell'unità, sebbene non in quelle pubblicamente dichiarate da Crucial sull'etichetta. L'unità pur trovandosi nello spazio ristretto di un laptop, funziona comunque con temperature sotto i 70° Celsius, soprattuto durante le sessioni di gioco. Questo è da aspettarselo, per tutti quegli ovvi motivi dovuti al modo in cui i videogiochi gestiscono il caricamento della grafica. L'attivazione della Momentum Cache ha permesso temperature di esercizio anche molto inferiori, durante il normale utilizzo.Devo segnalare solo un particolare fenomeno che ho riscontrato: utilizzando CrystalDiskInfo per misurare la temperatura, eseguendo aggiornamenti continui in brevi periodi di tempo (per esempio tenendo premuto il tasto F5), la temperatura del SSD sale, anche sopra i 70° Celsius. In poche parole, sembra che richiedere ripetutamente le proprietà dell'unità e le letture dei sensori al Controller Micron del P5, faccia in qualche modo aumentare la richiesta di performance e quindi la temperatura complessiva del SSD. Questo è uno di quei rari casi in cui lo strumento di misurazione interferisce con la misura stessa. Perciò consiglio vivamente di misurare la temperatura del SSD con un periodo di campionamento di circa 2-3 secondi. Questo è un particolare fenomeno che ho riscontrato solo sul P5 e su nessun'altro dei miei SSD NVMe.In conclusione, il Crucial P5 è un SSD estremamente veloce, ben progettato sia a livello architetturale che funzionale, che rispetta comunque le proprie specifiche interne, sebbene non sempre quelle dichiarate sull'etichetta. Quindi sento di dover dare 5 stelle a quest'ottima unità di memoria, che dovrebbe soddisfare sia l'utente medio che il gamer professionista.
