Apple Is Now Using SanDisk SSDs in the Retina MacBook Pro As Well

Autore: AnandTech

There has always been some level of lottery involved when buying an SSD-equipped Mac. The first Mac to start the lottery was the 2010 MacBook Air, which initially used Toshiba’s SSDs but later it was found that some units were shipping Samsung SSD 470 based drives. Up until last year Apple kept using the same Toshiba and Samsung SSDs; the 2012 refresh finally brought SATA 6Gbps SSDs to Macs and, of course, another round of lottery too. The 2012 MacBook Air kept using drives from both Toshiba and Samsung, albeit both were newer generation (Toshiba’s is SF-2281 based, Samsung is PM830). The rMBP, however, used only SSDs from Samsung, and the 256GB and 512GB SSDs in the MacBook Air were all Samsung made as well. 

Late last year it was discovered that some rMBPs might be using SSDs from SanDisk. At that time we only had system profiler screenshots and user reports to go with, which I didn’t think was enough to go by (after all, the controller is the most interesting part of the story anyway). Today, I have some pictures to show:

In short, that’s a custom version of SanDisk’s X100 mSATA SSD. The controller is Marvell’s 88SS9174, which is also used in Crucial m4, Intel SSD 510, and Plextor M5S, each with custom firmware. That’s coupled by eight (four on each side of the PCB) 24nm Toggle-Mode MLC NAND packages from SanDisk (SanDisk has a NAND joint-operation with Toshiba). Anand actually has an X100 in the house and just finished running tests on it a few days ago, so here’s a brief comparison of the SSDs used in Macs at the moment (Corsair Force GS is the closest match to the Toshiba SSD):

Heavy Workload 2011 - Average Data Rate

Light Workload 2011 - Average Data Rate

Note that these are all retail drives; the drives Apple is using are custom and hence the performance may be slightly different (customized firmware). The X100 in the graphs is actually a newer 88SS9175 based X100 (it might be X110 as SanDisk wasn’t very specific) so performance of the 9174 based might be slightly different (we shouldn’t be anywhere close to U100 speeds, fortunately). The 9175 is essentially just a low-power version of the 9174 with only four channels, so I wouldn’t be surprised if the 9174 based X100 was even faster. However, all the drives Apple uses are good performers. The SSD 830 is the fastest of them all but the X100 and Toshiba are trading blows as you can see above. 

I’m not surprised by Apple’s move. Apple is constantly buying more and more SSDs (and flash in general) and relying on just one supplier is risky. If one manufacturer has a hiccup in production, Apple still has the channel to quickly buy SSDs from another manufacturer. There’s also a possibility that the availability of Samsung PM830 is decreasing because it’s now a discontinued product. Samsung told me they still have plenty of stock for OEM and B2B customers but the volume Apple needs is fairly significant and Samsung may not be able to supply that anymore. Samsung does have a newer SSD 840 (Pro) available but it’s possible that Samsung’s pricing made Apple choose SanDisk.

Either way, SanDisk is now the third OEM to supply SSDs to Apple. I’ve only seen the X100 appear in the rMBPs so far but it’s certainly possible that we will see SanDisk SSDs in other Macs (such as the Air) too. While I’m sure most of the buyers would prefer the Samsung SSD (including myself), the good news is that none of the drives Apple is using are exceptionally bad. Unless your workload is very IO intensive, there shouldn’t be a significant difference in real world performance (except when dealing with incompressible data and the Toshiba drive).

  1. Lunedi 17 dovrei andare a cambiare il mio iphone 3gs al apple store e mi hanno detto che probabilmente ci sarà da cambiarlo poichè non si ricarica o roba varia, mi ha dato l’ appuntamento (qualche giorno fa) e mi ha detto di tornare il 17 dicembre, ma per avere un iphone nuovo (i mio è in garanzia eh) devo pagare??

  2. Allora se io comprassi un iphone in francia a nizza e poi il telefono mi si rompesse tipo due mesi dopo quando è ancora in garanzia, posso portarlo all apple store di milano? O devo per forza andare in quello dove l’ho comprato??

  3. Per mettere le immagini nel mio ipod nano apple 8gb devo per forza sempre sincronizzare la cartella o cè un modo di trascinare semplicemente le immagini tipo quelli della playlist musica???Grazie

  4. Vorrei comprare delle applicazione per l’iphone sull’apple store ma quando la voglio scaricare mi chiede di pagare con il numero della carta di credito. Io che non ho la carta di credito come faccio a pagare le applicazioni che voglio comprare?

  5. Salve.
    Mi hanno rubato l’iPod Touch ed ho chiamato il numero verde della Apple per informazioni,cliccando vari numeri sono riuscito a parlare con un operatore,ora il problema è questo,prima di parlarci mi ha chiesto il seriale dell’iPod, ed io sfortunatamente non sono riuscito a trovare la scatola.
    Comunque,gli ho fatto,ora non ce l’ho ma volevo sapere sono un’informazione e sono stato per circa 3 minuti a chiedergli se era possibile rintracciarlo.
    Ora ho paura che abbia speso molto ma prima della telefonata non diceva niente sui costi della chiamata…
    Possibile che mi venga la bolletta del telefono alta per aver chiamato la Apple senza seriale?
    Risposte serie da persone che sanno qualcosa.
    Grazie mille!
