SanDisk Ultra II 240GB SSD (SDSSDHII-240G) SATA 2.5 (Bulk Packaging)

Amazing ssd.I am very pleased I bought this SSD.The price was great 85$ !!!! And it works amazing. It makes my computer runs very very fast.I am using old dual pentium cpu 2ghz with gigabyte mother board of 800hz and 2gb memory. The computer worked very slow and even Internet surfing was imberrsing performance. The HD I had was 7200 rpm on sata2 but was 6 years old and the time didn't do well on it.The computer was a wrack.So first thing I upgrade the network infrastructure to be 40mb them I upgrade the network card to support 1gb later on I bought video card (Azuz ATI HD6450 1g) but surfing the Internet and performing trivial tasks such as Microsoft office programs was awful.I am glad to say that this SSD solved all my problems!!!!!Again - due to the low price and that it is the same performance as his competitors products, I must say I am very pleased.It is very small and have almost no weight. Just love it!!!!Took me 2 hours to install windows 7 office 2010 and all my other programs ~20 including photoshop and autocad.

Replaced the HDD in my 6 year old HP G60-530us Notebook computer with the SanDisk Ultra II 240GB. I was not sure there would be much improvement in speed with such an old computer. My computer has the intel ich9m/m-e family 4 port sata ahci controller and I could not find any information on the speed of this controller. The HDD is a Toshiba MK3263GSX SATA 2.6 specified with a 3 G bit/sec transfer rate.Replacement Process:First I cloned the HDD in my notebook using the Apriom notebook upgrade kit. Plug the cable in the kit into the SSD then into the USB port on the computer. Then I ran the EZ Gig IV cloning software that came with the kit. Selected the source drive (HDD in my computer) and the target drive ( the new SSD) and followed the prompts. It took 1 hour and 11 minutes to clone the 320GB HDD in my computer. After cloning I shut off my computer and removed the battery. Took the screws out and removed the panel covering the HDD on the bottom of the notebook. Removed the screws on the bracket holding the HDD in place. Slid the bracket and HDD out and removed the screw holding the HDD to the bracket. Performed all of the steps in reverse. Turned on the computer and voila ... it works!. .The Results:Using a program call HD Tune here are the results. OLD HDD SDDTransfer Rate Maximum 72.6 MB/sec 200.9 MB/sec ( 2.75 x improvement)Transfer Rate Average 48.2 MB/sec 186.4 MB/sec (3.86 x improvement)Disk Access Time 18.9 ms 0.252 ms ( 75 x improvement)Random Seek 4KB 0.203 MB/s 24.528 MB/s ( 121 x improvement)Random Seek 64KB 0.814 MB/s 70.325 MB/s ( 86 x improvement)Random Seek 8 MB 38.67 MB/s 243.85 MB/s ( 6 x improvement)Conclusion:Even though the computer is six years old it was worth upgrading to the SSD. For large file transfer the speed improvement was about 3 to 4 times. It would have been more if the computer hardware had been SATA III instead of SATA II.Where this upgrade really shines is with getting small file access and transfers. Since the disk access time is close to 100 x faster (0.2 ms for the SSD as compared to 18 for the HDD) a huge speed improvement is achieved when the computer is trying to access a bunch of small files.In my case the performance improvement was very significant. With the old hard drive the task manager would show high disk usage 80% plus with low read and write speeds a significant portion of the time. Now that is all gone and I am rarely if ever waiting on the hard drive.P.S. When I did a full system scan with Norton with the HDD installed I could not do anything else because the HDD access was maxed out. Now I can't do anything else because the CPU is maxed out ... the SDD can feed my feeble CPU all it can consume.

I can't comment on long-term reliability yet (but that's NEVER been an issue with the numerous SanDisk SD cards I've owned, so I hope it will remain true here, too) but so far, this drive is EXCELLENT.With my MacBook Pro and a bargain USB 3.0 enclosure, the performance is AWESOME! The Blackmagic speed test clocks transfers to and from this enclosure/drive at 392MB/second write and 430MB/second read. I copied a 20GB Lightroom folder with 1,000+ files from one external SSD drive to this one in about a minute-and-a-half.And of course it needs only the power from the USB port, and runs absolutely silent and cool.And it looks like it's come down another ten bucks... unless I have any future failures, I would SO buy this again.P.S. While not the most rugged enclosure you can get, I'm using this drive with an EasyAcc USB 3.0 enclosure that Amazon sells for around 13 bucks. Works great. Never again will I buy a spinning hard drive (this is my 5th SSD drive I've put into use in the last few years and none have failed.)This combo is a performance storage bargain!

Works good. C-drive in desktop for over a year. Still quick to boot up; about 10-15 seconds (Windows Vista). Quick enough. Never bothered with SanDisk updates and still reliable with no problems.A year later; shows 97% life remaining and about 3,900 Gb written. Used mainly for Windows Media Center and Internet. Had Team Fortress 2 for a few months. Always quick to boot with no problems.Took Steam off later only to be cautious of SSD's write life.Only problem had was the TRIM. Sandisk marketed the Ultra II to Vista users (don't remember about XP) that TRIM feature would work manually; then backed out of the claim it works at all.Over time it started sounding like a marketing gimmick; there's no real proof TRIM was working on windows 7 or newer OS. Moved on, today it don't bother me if it works or not when enabled because the eyes tell me its still quick.Vista user

Da ich generell klassische HD's favorisiere und bis jetzt nie eine SSD hatte, wurde es jetzt doch mal Zeit zumindest die Systemplatte zu aktualisieren. Mir ist nämlich Zuverlässigkeit und insbesondere viele GB's fürs Geld wichtiger als Geschwindigkeit.Natürlich waren die üblichen Verdächtigen wie die Samsung Evo's in der engeren Wahl. Jedoch hat mich bei der Sandisk dann doch der günstigere Preis überzeugt (und es muss nicht immer Samsung sein).Bei der Platte gibt es bis jetzt absolut nichts zu meckern. Funktioniert anstandslos und schnell. Die Zuverlässigkeit muss sich allerdings noch zeigen, da bin ich nach wie vor noch etwas skeptisch. Wenn nach 3 Jahren noch nichts war dann hat sie schonmal gute Karten :-)Die Umsiedlung von meinem Win 7 64 von der alten 160 GB Samsung HD (übrigens noch mit IDE Anschluss) ging ohne Probleme vonstatten. Hier die Schritte die ich dazu getätigt habe, falls jemand diesbez. Hilfe braucht:1. Die 2 Partitions von der HD (C: und E:) mit Acronis True Image 2013 auf ne andere interne Platte gesichert.2. Die alte HD abgehängt, SSD an nem freien SATA angeschlossen.3. Von der Acronis Boot CD gestartet und mit Acronis Disk Direktor die neue partitioniert.4. Nochmals von CD gestartet und mit True Image die gesicherten Images zurückgespielt auf die neue Platte5. Im BIOS die Bootprioritäten bzw. "Hard Disk Priorities" entsprechend geändert.6. Der 1. normale Start schlug allerdings fehl da der MBR nicht stimmte.7. Von der Win 7 Install-CD gebootet und die Startumgebung repariert.8. 2. Normaler Start war jetzt erfolgreich, allerdings war noch ein Kuddelmuddel bei den Laufwerksbuchstaben.9. Durcheinandergewirbelte Laufwerksbuchstaben in der Datenträgerverwaltung korrigiert10. 3. Start ging nun ohne Probleme wie gewöhnlich wie bei der alten, jedoch um ca. 50 % schneller.Zuletzt noch das Sandisk Dashboard installiert, liefert doch nützliche Informationen, insbesondere was die Lebensdauer betrifft.Bis jetzt völlig zufrieden mit der Platte und kann sie uneingeschränkt weiterempfehlen!

インテルのSSDからの乗り換え起動ディスク＆プログラムで使用　ドライブにゆとりができて早くもなりました

Installing this was a no-brainer. Very easy set-up and installation, product exactly as advertised. Had it installed for about a year now and have had no drops in performance since i put it in. This is VASTLY better than a standard HDD.

Questo è il terzo SSD sandisk che compro: 1 extreme e 2 ultra II,Sono prodotti ottimi per rapporto prezzo prestazioni. Anche l'affidabilità sembra essere buona e la garanzia è di 3 anni. Le prestazioni si avvicinano molto ai dati di targa e la velocità di scrittura decade (fino ad oltre la metà) solo se i file superano le dimensioni della cache denominata nCache 2. Ma quanto è grande la cache? 5GB ogni 120 GB nominali,quindi 10GB per questo modello. Inoltre solo i modelli da 480 e 960 GB hanno un controller Marvell a 8 canali mentre i tagli inferiori usano un controller Marvell a 4 canali.La cache è implementata non usando una memoria RAM,ma gestendo una porzione delle celle TLC in modalità SLC. Terminata la scrittura, i dati saranno spostati on-chip nelle più lente TLC nei momenti di non utilizzo, senza bloccare o rallentare l'accesso al SSD da parte del sistema operativo.Va da se che la cache funziona se c'è abbastanza spazio libero. Tenetene conto per usi AUDIO/VIDEO.Anche SanDisk non ha dotato i suoi SSD di un condensatore per evitare perdite di dati in caso venisse a mancare l'alimentazione dell'SSD, ma grazie al fatto che la cache sfrutta una memoria persistente, la sua coerenza interna è garantita, evitando così danni ben peggiori della perdita dell'ultima operazione.Per la sicurezza dei dati registrati, sandisk, usa internamente una modalità simile al RAID-5 dei dischi, il che garantisce una buona ridondanza.Nei confronti del Samsung Evo 850, appare un po' più lento in molti test, ma nell'uso generale le differenze velocistiche non si apprezzano mentre si apprezzano i 20 e passa euro di prezzo in meno.Tutti i modelli sono SATA III 6Gb.Uno l'ho installato su un portatile SATA II e funziona senza problemi anche se è un po' sprecato.Tanto per dare un metro di paragone da portatile spento al desktop usabile di windows 10 passano 10 secondi scarsi...Nella confezione è presente SSD, una cornice per portare lo spessore a 9mm, e del materiale informativo. NESSUN SOFTWARE per la migrazione/clonazione del disco è fornito o suggerito, ma per fortuna ne esistono di molto validi e gratuiti (Usatene uno che allinei le partizioni correttamente).La dashboard della Sandisk (solo x windows da scaricare da internet) consente di controllare in maniera semplice e veloce lo stato di salute dello SSD, di verificare la presenza di nuovi firmware, e controllare lo stato di occupazione dello spazio.In definitiva un prodotto consigliato.

I would recommend to anyone looking for a cost effective upgrade and speed increase (particularly if you have an older computer). To take full advantage, image/migrate or reinstall your operating system to the SSD and use you old drive as storage.
