AnandTech - OCZ Z-Drive R4 CM88 (1.6TB PCIe SSD) Review
We introduced the Z-Drive R4 in our Computex coverage earlier this year - it's a beast. The Z-Drive R4 is a multi-controller PCIe solution that uses either 4 or 8 SF-2000 controllers behind a SAS-to-PCIe 2.0 x8 controller. The breakdown is as follows:

| OCZ Z-Drive R4 Lineup | ||||||
| CM84 | CM88 | RM84 | RM88 | |||
| Capacities | 300/600/1200GB | 800/1600/3200GB | 300/600/1200GB | 800/1600/3200GB | ||
| NAND | MLC | MLC | MLC | MLC | ||
| Interface | PCIe Gen 2 x8 | PCIe Gen 2 x8 | PCIe Gen 2 x8 | PCIe Gen 2 x8 | ||
| Form Factor | Half Height PCIe | Full Height PCIe | Half Height PCIe | Full Height PCIe | ||
| Dimensions LxWxH | 168.55 x 68.91 x 17.14 mm | 242 x 98.4 x 17.14mm | 168.55 x 68.91 x 17.14 mm | 242 x 98.4 x 17.14mm | ||
| SSD Controllers | 4 x SF-2282 | 8 x SF-2282 | 4 x SF-2582 | 8 x SF-2582 | ||
| Power Failure Protection | N | N | Y | Y | ||
| Max Read | 2000MB/s | 2800MB/s | 2000MB/s | 2800MB/s | ||
| Max Write | 2000MB/s | 2800MB/s | 2000MB/s | 2800MB/s | ||
| Max Random Read | 250K IOPS | 410K IOPS | 250K IOPS | 410K IOPS | ||
| Max Random Write | 160K IOPS | 275K IOPS | 160K IOPS | 275K IOPS | ||
בחישוב מהיר, יוצא שכרטיס אחד כזה יהיה מסוגל להריץ 4-5 סטרימים של 4K בלי בעייה.
בשביל ~10,000 (6-7 דולר לג'יגה) דולר זה עדיין לא פתרון לכל כיס, אבל צפוי שהמחיר ירד משמעותית בעתיד הקרוב.
